           A quasi-natural experiment from China

    • Free pre-print version: Loading...

      Authors: Xinghua Cui, Xueping Ning, Ning Xu, Wenjie Zhang
      Abstract: Energy & Environment, Ahead of Print.
      This study explores the role of social credit system construction, an informal institution, in improving corporate environmental performance. To identify the causal connections between social credit and corporate environmental performance, the progressive difference-in-differences (DID) method is adopted by introducing the social credit system construction pilots aiming to improve the social credit environment of China as a quasi-natural experiment. Empirical results imply that social credit system constructions exert a significant improvement effect on corporate environmental performance. In addition, corporate innovation, financial constraints alleviation, and the strengthening of environmental cases enforcement are three effective action mechanisms by which social credit system constructions helping improve corporate environmental performance. Moreover, this promotion effect presents heterogeneity characteristics due to enterprises ownership and the environmental pollution degree of the city where the enterprise is located. This study provides an informal institutional perspective for the green development of enterprises.

  • Have the pilot carbon markets achieved synergistic control of carbon
           abatement and pollution reduction' The quasi-experimental evidence from
           China

      Authors: Tiantian Yang, Lan Yi, Jing Li, Qingquan Liang
      Abstract: Energy & Environment, Ahead of Print.
      The Chinese government has emphasized the necessity of synergistic control for carbon abatement and pollution reduction in the protection of eco-environment, as part of the 14th Five-Year Plan and the Long-range Objectives Through the Year 2035. As an important tool to reduce CO2, the carbon market can also affect the air pollution synergistically. The study utilizes the multi-period difference-in-difference (DID) model to analyze the impact of carbon market on carbon abatement, as well as the synergistic effect on different air pollutants. The study analyzes the mechanisms for carbon market to achieve synergistic control from the perspectives of “quantity” and “category” comprehensively. The findings indicate that: (1) carbon markets can reduce CO2 significantly, with a synergistic effect mainly observed on SO2 and soot (dust). These results remain robust when focusing on the industrial sector or adopting the PSM-DID estimation, etc.; (2) the mechanisms to achieve synergistic control vary among different air pollutants. Promotion of technology can only synergistically reduce SO2. Optimization of energy consumption structure is the top priority for reducing CO2. The most effective mechanism to achieve synergistic control of air pollutants is improvement of energy utilization efficiency; (3) to achieve synergistic control goals, the Chinese national market should prioritize industries that release both CO2 and NOx in the rolling-out plan, enrich the trading tools, and formulate effective price signals.

  • Estimating the impact of fishery industry on marine pollution: New
           insights from Method of Moments Quantile Regression

    • Free pre-print version: Loading...

      Authors: Mohd Alsaleh, Xiaohui Wang, Zhang Nan
      Abstract: Energy & Environment, Ahead of Print.
      Indeed, waste from marine may have a significant negative economic impact on coastal towns, tourism, shipping, and fisheries. Given its accumulation and spread, waste from marine may be one of the most urgent dangers to the sustainability of marine life and the health of the EU's waters. By considering the role of production in fisheries, fossil fuel use, economic development, and governance from 1990 to 2022, this research seeks to explore the dynamic influence of the fisheries sector on marine hazardous waste in 27 European nations. At higher quantiles, the findings showed a strong positive association between fisheries capacity production and marine hazardous waste at a 1% statistical level using the new Method of Moments Quantile Regression with fixed effects. From the fifth through the ninth quantiles (≈0.250), fishery output considerably increases marine waste, with a more substantial influence at the highest (≈0.239) and a lower impact at the lowest quantile (≈0.056). The findings also show that affluent countries in the EU14 have more significant at a 1% statistical level beneficial effect on marine waste than developing nations in the EU13. Using fossil fuels increased marine waste across all quantiles at a 1% statistical level. Still, economic development in EU14 developed and EU13 developing countries causes marine waste to decrease, at 1% and 10% statistical levels, respectively, supporting the growth theory for nations that produce fisheries. From the first through the ninth quantiles (≈−6.677) in EU27 nations, the influence of governance was adversely significant at a 1% statistical level. The findings suggest that the developed EU14 countries are more affected negatively by governance on marine waste. Using effective and environmentally friendly technology, policymakers may reduce marine waste in the EU14 and the EU13 nations while achieving sustainable development objectives.

           technological innovation and trade openness

    • Free pre-print version: Loading...

      Authors: Qiang Wang, Xinchen Cheng, Rongrong Li
      Abstract: Energy & Environment, Ahead of Print.
      In order to better understand the digital economy on carbon emissions, the intermediary effect model based on technological innovation and the panel threshold model based on trade openness and energy intensity are used to study the relationship between the digital economy and carbon emissions in G7 countries. In addition, a quantile regression analysis on the impact of the digital economy under different carbon emission levels is also conducted. The empirical results show that: (i) the digital economy has a significant inhibitory effect on per capita carbon emissions. (ii) The mechanism analysis shows that the digital economy can indirectly affect per capita carbon emissions by affecting technological innovation. (iii) The threshold effect of trade openness and energy intensity is significant. Under high openness and low energy intensity, the digital economy has a stronger inhibitory effect on per capita carbon emissions. (iv) The quantile regression results show that the carbon emission reduction effect of the digital economy is greater at the low-carbon emission level.

      Authors: Silu Chen, Chenling Tian, Xia Jiang, Jiaxin Lai
      Abstract: Energy & Environment, Ahead of Print.
      Although environmental regulations are effective forces to conduct green innovation, the existing research has not yet reached a consensus on the relationship between environmental regulations and enterprise green innovation. The objective of this study is to explore the influence mechanism of environmental regulations (i.e., market-based and command-based) on enterprise green innovation from the perspective of social information processing theory and regulatory focus theory. A time-lagged survey based on a Chinese sample of 184 firms supports the hypothesized moderated mediation model. The results show that (a) environmental regulations positively impact enterprise green innovation; (b) top management team (TMT) harmonious environmental passion climate fully mediates the relationship between market-based environmental regulation and enterprise green innovation, while TMT environmental performance anxiety climate partially mediates the relationship between command-based environmental regulation and enterprise green innovation; (3) chief executive officer (CEO) promotion regulatory focus moderates the positive impact of TMT harmonious environmental passion climate on enterprise green innovation, and CEO prevention regulatory focus moderates the positive impact of TMT environmental performance anxiety climate on enterprise green innovation. These findings extend the green innovation literature on how and when environmental regulations affect enterprise green innovation.

  • Can industrial agglomeration affect biodiversity loss'

    • Free pre-print version: Loading...

      Authors: Lu Xing, Shuhong Wang
      Abstract: Energy & Environment, Ahead of Print.
      Reducing the rate of species extinction and protecting biodiversity are major international concerns. The loss of biodiversity is closely related to international trade as an inevitable result of industrial agglomeration and improvements in green economy efficiency. In contrast to previous studies on biodiversity loss from the perspectives of deforestation, hunting, and fire, this study examines biodiversity loss from an international trade perspective, calculates the biodiversity footprint of each country as an indicator of biodiversity loss, and innovatively elaborates on the theoretical mechanisms of industrial agglomeration, green economy efficiency, and biodiversity loss. An empirical analysis used panel data from 148 countries from 2006 to 2020. This study identifies that industrial agglomeration directly and indirectly aggravates biodiversity loss through green economy efficiency, which mediates the relationship between industrial agglomeration and biodiversity loss. The effects of industrial agglomeration and green economy efficiency on biodiversity loss driven by export trade in developed and developing countries are consistent with the benchmark test results. The effect of industrial agglomeration on green economy efficiency is positive in developed countries and vice versa in developing countries. By region, green economy efficiency can significantly mitigate the embodied biodiversity loss in the export trade in Asia, Africa, and North America, whereas its influence in Europe and North America is insignificant. This study extends the perspective of biodiversity research from the natural to economic fields, delves into the underlying economic causes of the current state of trade-driven biodiversity loss, and provides important evidence for reducing biodiversity losses caused by international trade.

  • Performance of the autoregressive integrated moving average model with
           exogenous variables statistical model on the intraday market for the
           Denmark-West bidding area

    • Free pre-print version: Loading...

      Authors: Marko Lucic, George Xydis
      Abstract: Energy & Environment, Ahead of Print.
      This article aims to investigate whether a statistical model known as Autoregressive Integrated Moving Average with Explanatory Variables can aid better predictability of volume-weighted average electricity prices compared to a commonly used forecasting method. This analysis was conducted for a specific bidding area, the Denmark-West bidding area (DK1). Autoregressive integrated moving average model with exogenous variable's performance was tested on the DK1 intraday market over a two-year period starting from 1 January 2019 until 31 December 2020. An explanatory variable used to support better the accuracy of the forecast is the day-ahead price for a corresponding intraday delivery hour. To ensure the validity of the paper, a well-known forecasting methodology was applied, and the results of the analysis show superior performance over the benchmark forecasting method. The autoregressive integrated moving average model with exogenous variables model developed was found to significantly outperform other commonly used forecasting methods, with an average mean absolute percentage error of 1.5%. The model was able to accurately predict intraday volume-weighted average prices up to 24 h in advance, using only publicly available data on day-ahead prices and historical intraday prices. Energy traders and other market players may find the developed autoregressive integrated moving average model with exogenous variables model to be a useful resource when looking to make more informed decisions in the intraday market.

  • Spatial analysis of carbon emission effect of financial development in
           Africa: The role of energy and socioeconomic factors

      Authors: Delphin K Espoir, Benjamin M Mudiangombe, Regret Sunge, Andrew A Alola
      Abstract: Energy & Environment, Ahead of Print.
      The need to mitigate global warming has led policymakers and other stakeholders to see further understanding of the driving forces behind CO2 emissions. Financial development has been identified among the most influential factors. However, its importance has not been well explored in developing countries, especially in Africa. Several studies have explored the CO2 emissions-effects of financial development in Africa but focused on the temporal aspect and overlooked the spatial dependence which has the potential to influence the estimated marginal effects. In so doing, they consider each country as an island which tends to suggest that there are no spatial spillover effects that could originate from countries’ proximity. In this study, such an inaccurate assumption is relaxed by deploying a spatial Durbin model to explore the spatial dependence in the financial development-CO2 emissions nexus for 52 African countries between 1995 and 2017. Our results reveal a significant positive direct effect (0.020) on financial development in a given country and a significant positive indirect effect (0.074). Thus, our estimated marginal effects show a positive and significant total effect (0.095), indicating that a 1% increase in financial development will result in a net increase of CO2 emissions of about 0.095%. This finding implies that financial development contributes negatively to the surge of CO2 emissions in Africa. While the environmental Kuznets curve hypothesis is validated in the continent, renewable energy utilization is found to posit significant environmental effects. This finding is crucial to policymakers as it stands as a reminder about the role of the neighbourhood in designing and implementing environmentally friendly policies that aim at reducing pollution in Africa.

           relation to environmental degradation in the five most populous countries
           in Asia

      Authors: Arshad Ali, Guo Xiangyu
      Abstract: Energy & Environment, Ahead of Print.
      This study aims to examine the impact of globalization, renewable energy generation, and agricultural value addition on the ecological footprint (EF) and carbon emissions (CO2) of selected five most populous countries in Asia during the period 1975–2020. The Westerlund cointegration test supports long-term cointegration relationships among the considered variables in selected countries. The long-term elasticity results of the mean group, augmented mean group, and common correlated effects mean group estimators clearly show that agricultural value added and globalization make significant contributions to the ecological footprint and carbon emissions of the five most populous countries in Asia. However, renewable energy generation significantly reduces the ecological footprint and carbon emissions. Moreover, the impact of gross domestic product (GDP) on ecological footprint and carbon emissions is significantly positive while the impact of GDP2 on ecological footprint and carbon emissions is significantly negative, thus validating the inverted U-shaped Environmental Kuznets Curve hypothesis for specific Asian densely populated countries. The results of the causality test indicated a two-way causality between renewable energy generation and ecological footprint, supporting the feedback hypothesis. There is also a two-way causal relationship between agricultural value added and ecological footprint. Overall, these empirical results show that renewable energy plays a prominent role in combating environmental pollution in selected densely populated Asian countries. Thus, these countries should achieve their sustainable development goals by cultivating existing renewable energy generation policies. Moreover, specific densely populated countries in Asia should encourage clean energy production and consumption in the agricultural sector, and increased investment in renewable energy can improve environmental quality and agricultural production.

      Authors: Monique Holowach, John R Parkins
      Abstract: Energy & Environment, Ahead of Print.
      Wind energy development can be polarizing with opposition coming from rural regions that are most affected by new wind farms. Local opposition can become further entrenched through political ideologies, where one's perspective on wind turbines becomes a litmus test for one's political position. With these concerns in mind, we utilize results from a survey of large-scale agricultural landowners in Alberta, Canada, to answer the following question. To what extent are self-declared political positions consistent with views on wind energy development' Results indicate that wind energy acceptance is not politically polarized nor even polarized among Alberta's rural landowners. Instead, the sample reveals fragmented, moderate, and likely malleable opinions about wind energy. Within a jurisdiction that is politically conservative and fossil fuel dependent, these results have largely positive implications for future wind energy development in the province.

      Abstract: Energy & Environment, Ahead of Print.
      The goal of this research is to address the electrical magnetohydrodynamic flow of hybridity nanoparticles through a stretched surface with the impact of the Darcy–Forchheimer permeable medium. By identifying appropriate similarity factors, the partial differential equation is converted into a set of ordinary differential equation with the help of R-K fourth-order approach based on shooting technique. The velocity, thermal, friction factor coefficient, and heat transport are investigated comprehensively for the influence of numerous blossoming parameters refer to in the present study by plots graphically. It is accomplished that due to the influence of the electric field associated with first- and second-order velocity slip impacts, the motion of liquid slows down. Moreover, the stream velocity grows for the boosting scales of mixed convection, which leads to eliminating sticking impact. The variation of important flowing variables on heat transport and the drag coefficient is also investigated. Here augmenting valuation of mixed convection parameter corresponds to boost up velocity curve. Furthermore, the influence of thermal field and heat transport are similar in view of the Biot number.

  • The impact of eco-innovation and economic growth on carbon emission:
           Evidence using novel QARDL approach

      Authors: Li Li, YunQian Zhang, Ching-Chi Hsu, Nguyen The Vinh, Ky Nguyen Tran, Thanh Quang Ngo
      Abstract: Energy & Environment, Ahead of Print.
      High economic growth in fast growing country like China is not without its environmental repercussions and eco- innovations have been promoted as a successful strategy for striking a balance between environmental performance and economic growth. However, there has not been much focus on how eco-innovation affects the performance of carbon emission in China. This study estimates the impact of eco- innovation on CO2 emission under the Environmental Kuznets Curve (EKC) hypothesis over the 1986–2022 period. To estimate the nexus empirically, we applied Quantile ARDL (QARDL) approach. The results of the research reveal that eco-innovations have significant yet negative effect on CO2 emission at all quantiles (0.05–0.90). Economic growth is linked positively with carbon emission over 0.05 to 0.70 quantiles, whereas its square impacts CO2 emission negatively and significantly at 0.60 to 0.95 quantiles. These findings confirm that EKC hypothesis exists in China. The findings in short run find that eco-innovations had negative impact on carbon emission, whereas in case of economic growth it shows positive connection, however, the GDP sq. shows negative linkage. On the basis of these results, the research recommends Chinese authorities to promote eco-innovations by providing influential incentives to households and business sectors to eliminate the negative trends of economic growth on environment. In addition, the study recommends that “renewable energy law” needs be implemented by institutions to encourage the renewable energy use in all sectors that is proved to have positive environmental impacts for China.

      Abstract: Energy & Environment, Ahead of Print.
      Among various energy storage devices, one of the emerging classes to be considered nowadays is advanced eco-friendly supercapacitors. Despite vast research regarding their electrochemical performance, there is still room for further refinement. Here, such an attempt has been made by producing nanocomposites of NiCoMn ternary transition metal-organic frameworks (MOFs) with conductive-natured carbon nanotubes (CNTs) functionalized with polyaniline (PANI). A rather different approach i.e., ultrasounds assisted solvothermal method has been employed to prepare the MOFs and their nanocomposites with varying concentrations (0, 20, 40, 60 mg) of PANI functionalized CNTs (PC). A comparison analysis suggests that NiCoMn/PC-40 (40 mg PANI-CNTs) has shown excellent electrochemical performance. In the material of worth attention, the formation of flower-like morphology and crystallinity was explored and confirmed by SEM and XRD characterizations. FT-IR analysis facilitated the exploration of compositional and functional groups of the best-performing material. The large cyclic area, highest specific capacity, excellent stability, less ion transport resistance, and excellent morphology proved NiCoMn/PC-40 as an excellent next-generation supercapacitor battery-grade material with the dominance of diffusive response (71.7%). It has been shown 1194 C/g of specific capacity with an extraordinary energy density of 82 Wh/kg and 1105 W/kg of power density by the NiCoMn/PC-40. At 20 A/g, 100% cyclic stability after 5000 charge/discharge cycles with 97.5% columbic efficiency was achieved. In essence, the excellent electrochemical performance, ease of fabrication, and affordable cost can provide a breakthrough in value addition of NiCoMn/PC-40 worth as a proficient energy storage material.

    • Free pre-print version: Loading...

      Authors: Peilun Li, Huilin Zhang, Caiting Yang, Jiafeng Zhang
      Abstract: Energy & Environment, Ahead of Print.
      Recently, a great deal of literature has discussed the effects of the carbon emissions trading scheme (CETS) and the factors that affect the corporate environmental information disclosure (CEID) level. However, no researchers have studied how CETS affects the CEID level. Based on a difference-in-difference-in-differences model, we discover that CETS can improve the CEID level. The findings are robust and persistent even after testing for time lags and leads effects, changing the measure of the dependent variable, testing for enterprise relocation, adjusting the fixed effect method, testing for concurrent policies, and performing placebo tests. The reason is that CETS can encourage corporate green technology innovation and environmental protection investment, thus improving the CEID level. Further investigation reveals that the impact of CETS on promoting the CEID level is more significant when the following conditions are met: the enterprises are in provinces and cities in the east and northeast; they are state-owned; and they have strong political connections. This paper expands on the current field of research on the influence effects of CETS, broadens the understanding of the factors influencing the CEID level, and investigates the mechanism by which CETS improves the CEID level.

      Authors: Mazyar Ghadiri Nejad, Reza Vatankhah Barenji, Güldal Güleryüz, Seyed Mahdi Shavarani
      Abstract: Energy & Environment, Ahead of Print.
      Many manufacturing companies are always looking for a way to reduce energy consumption by utilizing energy-efficient production methods. These methods can be different depending on the type of products and production technology. For instance, one of the ways to increase energy efficiency and keep the precision of production is to use robots for the transportation of the parts among the machines and loading/unloading the machines. This technology is affordable compared to the technologies used in manufacturing companies. Manufacturing companies that rely on robotics technology must have a strategy to reduce energy costs and at the same time increase production by adjusting the intensity of processing or controlling the production rate. This study presents an exact solution method for flexible robotic cells to control the production rate and minimize energy consumption, which aims to both reduce electricity prices and minimize greenhouse gas (GHG) emissions under a lead time of production. Then, considering the NP-hardens nature of the problem, a heuristic solution method based on the genetic algorithm (GA) is proposed. Using the proposed approach, manufacturing companies will be able to make more accurate decisions about processing intensity and process scheduling while ensuring sustainability.

      Authors: Victor Te Cheng Liao
      Abstract: Energy & Environment, Ahead of Print.
      Some fishery and environmental organizations criticize offshore wind farms affecting fishery livelihood and marine ecological biological environment. The problems offshore wind farm directly affect the fishing ground due to ocean currents, marine ecology, and the marine environment being changed. In addition, fishing operations may carelessly damage undersea offshore wind farm cables disrupting energy operations, many fishing activities are restricted within the offshore wind farm areas and marine ecological biological environment has been damaged by offshore wind farm. However, marine spatial planning could coordinate offshore wind farm stakeholders and conducts marine environmental impact assessments to identify suitable offshore wind farms. The purpose finds solutions for offshore wind farm in the fishery and marine ecological biological environment. The research questions are how to reduce offshore wind farm impact on fishery livelihood and marine ecological biological environment through marine spatial planning and marine environmental impact assessment in the Taiwan territorial waters. In online questionnaires of 404 respondents, 64.36% supported marine spatial planning site selection and marine environmental impact assessment could reduce offshore wind farm impact; 66.83% agreed offshore wind farm coexistence with multiple uses, increasing fishery and biodiversity; 58.17% agreed on public financial participation in offshore wind farm to increase social acceptance. The findings are consistent with previous research. However, interviewees challenged that multiple uses coexistence might affect some populations in the ecosystem and further investigations are required. Another, 50.50% agreed on updated regulations of marine spatial planning, marine environmental impact assessment, insurance, specific fund, feedback, and compensation of offshore wind farm that could improve fishery livelihood and marine ecological biological environment. Finally, based on the study results, the paper suggests that energy policy could open public financial participation in offshore wind farm increasing social acceptance, skill training influenced groups for employment, enhancing fishery livelihood, and protecting marine ecological biological environment.

      Abstract: Energy & Environment, Ahead of Print.
      This article proposes a hybrid method to design and manage the electronic vehicle payment station network in the event of power demand uncertainty. The proposed method is an integrated process with confusing virtual-anticipation and chemical reaction enhancement, hence named as chaotic quasi-oppositional chemical reaction optimization (CQOCRO) method. The key objective of the CQOCRO method is to develop a reliable model to assist in the design and management of an EVCS location, power supply line hazard and power demand entropy. The CQOCRO method creates a random nonlinear model of disruption that includes equivalent tactical outcomes and operational outcomes for designing and managing a stable EVCS network in the event of power demand uncertainty. Because of the extreme electricity flow, the power line is overheated which is handled by the proposed method. The proposed method addresses the possibility that excessive current flow-related line overheating could result in power line failure. The design of EVCS is based on the factors like type of power supply network, location and opening hours of charging stations, limited resources, potential for power supply line failure due to high load, and uncertainty of power demand. Accordingly, the performance of the CQOCRO method is done in MATLAB platform and the performance utilizes the existing techniques.

  • Unraveling the interplay between food security, agriculture, trade policy,

      Abstract: Energy & Environment, Ahead of Print.
      Food security, energy dynamics, and environmental sustainability represent some of the most critical global challenges in the contemporary world. This research undertakes the intricate task of deciphering the multidimensional impacts of food security, agricultural practices, trade policy, and energy consumption on the evolution of greenhouse gas emissions in South Korea spanning the period of 1990–2020. Employing a sophisticated autoregressive distributed lag approach, this study strives to extract both short-run and long-run interpretations. Moreover, the integration of a vector error correction model serves to illuminate the underpinnings of causal relationships. The findings reveal that nonrenewable energy consumption and food security impose a deleterious effect on environmental sustainability, predominantly via their enhancement of greenhouse gas emissions. In contrast, renewable energy consumption, agriculture, and trade policy emerge as key drivers of environmental sustainability due to their potential to mitigate greenhouse gas emissions. The vector error correction model corroborates the existence of short-term bilateral causality among food security, energy consumption, and greenhouse gas emissions. Yet, agriculture and trade policy display a unidirectional influence in the short term, effectively reducing greenhouse gas emissions. This causal nexus lends credence to the significant implications of short-term agricultural and trade policy decisions on greenhouse gas emissions. The study ultimately underscores the imperative role of government intervention in South Korea in fostering energy-efficient and environmentally responsible strategies for greenhouse gas emissions reduction and enhanced environmental sustainability.

      Abstract: Energy & Environment, Ahead of Print.
      This research employs the modified undesirable slack-based measure dynamic exogenous data envelopment analysis model to evaluate the construction industry efficiency in 30 provinces of China from 2006 to 2017. It considers the differences in urbanization levels in three (east, central, west) regions and evaluates the profitability, resource allocation, energy consumption, and carbon emission efficiency of the construction industry. The results are as follows. First, the construction industry efficiency is the best in the east, followed by the central region, and lowest in the west. Second, the changing trends in this industry's efficiency are widespread across the nation's regions. The highest point of efficiency in the east region is at the beginning of the research period, but it then declines. The efficiency value of the central region reaches its peak around 2012 and then falls. The west region experiences increasing efficiency year-by-year until peaking in 2017. Third, depending on the degree of urbanization, its effects are also diverse. Therefore, the China government must examine the degree of urbanization to avoid environmental problems brought by urbanization that can bring about a drop in efficiency of the construction industry.

  • Evaluating carbon payback time by optimizing insulation materials for
           different orientations: A cradle-to-gate life cycle assessment

      Authors: Ali Rafat Gigasari, Javier Cárcel-Carrasco, Luis Manuel Palermo Iglesias, Nima Amani
      Abstract: Energy & Environment, Ahead of Print.
      The European Union aims to reduce greenhouse gases emissions by 80–95% compared to 1990 levels by 2050. Therefore the life cycle concept has gained widespread acceptance as a model for evaluating the environmental impact of goods and services. In this study, the optimal thickness of various insulation materials for external walls, roofs, and floors using a Mediterranean climate zone's hot summers and mild winters for a hypothetical residential building for four cardinal orientations was determined. The criteria for determining the optimum thickness represent a turning point in terms of cooling energy consumption (electricity). The optimum thickness of nine different types of insulation materials was defined using the aforementioned approach. These materials included aerogel, polyisocyanurate, polyurethane, extruded polystyrene, expanded polystyrene, phenolic foam, cellulose fiber (cellulose), mineral wool, and glass wool (GW). The purpose of this paper is to calculate the carbon payback time (CPBT) using the cradle-to-gate life cycle assessment method by considering the global warming potential (GWP) of insulation materials at their optimum thickness. The CPBT is calculated as the ratio of the total building's GWP to the GWP of savings from cooling and heating (electricity and natural gas). The results indicated that when evaluating the average CPBT for four cardinal orientations (FCO), aerogel has the longest CPBT of 2.34 years, and GW has the shortest CPBT of just 0.09 years. Aside from cost payback time, the findings of this study provide a new perspective on selecting appropriate thermal insulation.

      Abstract: Energy & Environment, Ahead of Print.
      In order to explore an effective method for the effect of collaborative governance on SO2 pollution from thermal power energy consumption in the Yangtze River Delta (YRD) urban agglomeration, the spatiotemporal evolution of SO2 pollution from thermal power energy consumption was empirically studied by Moran's I first; then the revised Difference-in-Difference-in-Differences model was constructed to examine the effect of collaborative governance on SO2 emission intensity from thermal power energy consumption, and the time effect of collaborative governance was also examined; finally, the Grey System Prediction Model was used to forecast the SO2 emission intensity from thermal power energy consumption in YRD urban agglomeration from 2021 to 2025. The results show that SO2 emissions from thermal power energy consumption in YRD urban agglomeration have positive spatial autocorrelations, and high-high spatial clusters have the tendency of moving to inland cities from coastal cities. Moreover, SO2 pollution from thermal power energy consumption in YRD urban agglomeration has improved year-by-year after the implementation of collaborative governance and the predicted SO2 emission intensity from thermal power energy consumption in YRD urban agglomeration generally shows a downward trend.

      Abstract: Energy & Environment, Ahead of Print.
      This study examines the triboelectric behavior of fibers that are readily available and were obtained from the bombax ceiba tree (BOM) and the calotropis plant (CALO). A triboelectric nanogenerator (TENG) is fabricated from these fibers as charge-generating layers that produce a charge by contact electrification. The properties of these fibers which include surface morphology and crystallographic nature are examined using different characterization techniques. Scanning electron microscopy images reflect more roughness in CALO as compared to BOM whereas both materials show an almost amorphous nature in X-ray diffraction data. Further, both materials show tribopositive nature when tested against polytetrafluoroethylene (PTFE) and nylon. While examining their electrical performance, the CALO–PTFE pair produced 11.1 V while 10.7 V is generated from the BOM–PTFE pair. These combinations are capable of illuminating multiple light-emitting diodes of the green spectrum and can derive one digital calculator. Lastly, the dependency of TENG performance on the contact area of active layers is analyzed. From the results obtained, it is concluded that these materials can potentially power small electronic gadgets and can contribute to the growth of a sustainable civilization.

           New perspective on the Porter hypothesis

    • Free pre-print version: Loading...

      Authors: Godwin Olasehinde-Williams, Ajide Folorunsho
      Abstract: Energy & Environment, Ahead of Print.
      This study tests the validity of the Porter hypothesis through the examination of the joint effects of green trade and environmental policy stringency on sustainable development in the European Economic Area. To achieve the study objective, data for 14 countries within the region between 2003 and 2015 is analyzed using advanced panel estimation techniques – panel method of moments quantile and nonparametric time-varying coefficient panel models. The empirical analysis yields a number of interesting results. In confirmation of the Porter hypothesis, the interaction term is positive and significant. Specifically, a percentage increase in environmental policy stringency raises the positive impact of green trade on sustainable development by 0.005%. This interactive effect also ranges between 0.002% and 0.007% across quantiles. This indicates that the higher the level of sustainable development, the higher the moderating impact of environmental policy stringency on the relationship between green trade and sustainable development. This suggests that stringent policies are able to induce green technological shocks that cause efficiency improvements and innovation, which in turn promote sustainable development either directly or indirectly through their interactions with green trade. Moreover, the individual and synergistic impacts of environmental policy stringency and green trade are time-varying and sensitive to economic conditions. They become more pronounced in periods of major regional/global economic events. Responsible use of strict environmental policies is advocated, and the removal of green trade barriers is encouraged.

           Cross-country evidence

    • Free pre-print version: Loading...

      Authors: Muhammad Qayyum, Shijie Li, Gao Jian, Yuyuan Yu
      Abstract: Energy & Environment, Ahead of Print.
      Low attention has been paid to the environmental effects of imported cultural commodities, which serve as a medium for cultural engagement and information sharing around the globe. Using the generalized method of moment (GMM) approach, this article empirically assesses the effects of imported cultural products on carbon emissions using cross-country panel data from 2004 to 2017 for 121 countries. The empirical findings reveal that the environmental consequences of imported cultural commodities vary among income level country groups. Overall, a 1% increase in the imports of total cultural goods imports would decrease carbon emissions significantly by 0.002%. After dissecting the sample into two groups, we find that a 1% increase in total cultural goods imports would lead to a significant decrease in carbon emissions of higher-income countries by 0.008%, but a significant increase in the emissions of carbon dioxide of lower-income countries by 0.002%, thus showing the importance of worldwide cultural interaction to carbon emissions. In addition, we find that performance & celebration goods and audiovisual & interactive media goods are primarily responsible for the inhibiting effects of imported cultural goods on the carbon emissions of higher-income countries. Imports of the majority of cultural products (with the exception of heritage items) would result in a significant rise in carbon emissions for low-income nations, a conclusion that is consistent with that of overall cultural goods imports. Gross domestic product per capita and economic complexity index have consistently negative effects on carbon emissions across several models for both nation groups, although energy consumption is the most significant contributor to carbon emissions. In addition, using Lasso Poisson regressions, we undertake robustness tests to assess the dependability of our empirical results based on the GMM methodology. The Lasso Poisson estimation results are consistent with our earlier findings.

           using different pretreatment techniques: A mini-review

      Authors: Kehinde O. Olatunji, Daniel M. Madyira, Jacob O. Amos
      Abstract: Energy & Environment, Ahead of Print.
      Macroalgae can be grown without the use of fertilizer, fresh water, or arable land. These qualities support its use for biofuel production because it frees up land for other traditional energy sources and food crops. It has been investigated as biogas feedstock to substitute for fossil fuels burning with attendant effects on the ecosystem. The microstructural arrangement of macroalgae biomass is restricting their conversion to biogas. Therefore, application of pretreatment before anaerobic digestion is needed to enhance their availability to microbial degradation and subsequent increase in biogas yield. Pretreatment application for substrate catalysis is vital to recovering eco-friendly and economical energy from macroalgae. This study summarizes the state of the art of various pretreatment methods employed to enhance macroalgae biomass's anaerobic digestion process. These methods were categorized as thermal, biological, chemical, nanoparticle additives, mechanical, and combined. Merits and challenges associated with each of these methods were also considered. The study shows that all the pretreatment methods considered can improve the biogas yield if the appropriate method is selected based on the type of macroalgae species. Pilot-scale studies that will assist in assessing their feasibility on the full-scale implementation are still missing.

      Authors: C Ramesh, M Vijayakumar, G Kumaresan, Benjamin Franklin Selvanayagam
      Abstract: Energy & Environment, Ahead of Print.
      A hybrid method for improving the efficiency of heat pipe evacuated-tube solar-collector (HPETC) is proposed for incorporating the phase-change materials (PCMs) in both off-demand and regular operation. The proposed hybrid approach is called an improved honey badger algorithm (HBA). The crossover and mutation operator improves the honey badger's (HB) foraging habit. The proposed approach aims to generate hot air at various rates of airflow under incident and nonincident solar-radiation situations. The analysis is done on the effects of different energy-storage systems and the position of the heat pipe (HP). In a normal heat-pipe evacuated-tube solar collector, the HP is put within the glass tube that is closer to the upper-surface, and it is held in place through an aluminum fin. However, in the proposed method, the HP is rearranged in the tube's middle. In order to identify the PCM with the highest average-fin temperature, the temperatures of the area-weighted average-fin are measured and compared throughout the glass tubes under typical conditions. For maximizing the thermal-energy carrying capability, the average liquid fraction volume of PCMs is measured for a 24-h flow period. The average liquid-fraction volume of PCMs is continuously observed in stagnation mode till the glass tube reaches the maximal value. The structured mesh patch conforming method is used to invalidate the HPETC system's constituent parts, improving numerical stability and convergence. The proposed method efficiency is 0.43. The proposed method shows high efficiency compared with other existing methods.

      Authors: B Musthafa, MA Asokan
      Abstract: Energy & Environment, Ahead of Print.
      The polyunsaturated fatty acid methyl ester concentration in Prosopis juliflora biodiesel drops the cetane number and affects ignition quality. In this study, two fuel reformulation strategies, viz. partial hydrogenation and the inclusion of Di-tert-butyl peroxide (DTBP), are investigated for their ability to improve the combustion and performance of a diesel–biodiesel (B20) blend without compromising the emissions trade-off. An autoclave reactor utilizes partially hydrogenated juliflora biodiesel and gas chromatography to determine the altered fuel composition. The cetane improver is DTBP, which is mixed with B20 at a concentration of 2000 ppm. The filterability of the test fuel was evaluated using the Tamson filter blocking tendency apparatus. Engine parameters and emissions of the base diesel (D0), JB20, HJB20, and JB20 + DTBP test fuels were examined in a diesel engine. According to the FBT results, JB20 (1.36) and HJB20 (1.28) have good filterability, which is consistent with the ASTM standard (D2068-14). While comparing JB20 blend with modified JB20 fuels decreases NOx (up to 5.24%) and increases brake thermal efficiency (7.5%) at full load. Compared to diesel fuel, partially hydrogenated blend fuel emissions viz. HC, CO, and smoke were reduced by 15.24%, 7.76%, and 10.14%, respectively. Based on the above results, partial hydrogenation is more beneficial than the inclusion of DTBP in enhancing biodiesel's trade-off qualities.

      Abstract: Energy & Environment, Ahead of Print.
      Since China's low-carbon pilot policy (LCPP) was launched in 2010, it has moved closer to accomplishing its carbon peak and neutrality targets. However, there is still scant literature on how to accurately consolidate the achievements of the policy in the pilot cities within which it was implemented. This research seeks to address the gap in the current literature by providing a theoretical basis for estimating the effect of LCPP on urban CO2 using a multi-period difference-in-differences model. Panel data from 283 Chinese cities from 2006 to 2019 was utilized. We found that: (1) The LCPP evidently reduced the pilot cities’ CO2. (2) Mechanism verification shows that the LCPP curbs CO2 emissions by improving urban technological innovation and reducing energy consumption. (3) Heterogeneity analysis displays that the CO2 reduction effect is more pronounced in eastern areas, non-resource-based cities, and urban agglomerations. The LCPP has accelerated China's CO2 reduction process and provided Chinese characteristics methods for limiting CO2 emissions and reducing climate change. This is crucial for advancing urban low-carbon governance in the broader country.

      Abstract: Energy & Environment, Ahead of Print.
      The Independent System Operator (ISO) plays a key role in a competitive electrical system by controlling the market with the received bidding from the different market participants. The ISO settled the energy at the location-based marginal pricing (LBMP) where all the participants get economic benefits. In the renewable combined system, the future renewable power production data need to be submitted to the ISO at least one day before the operation. There is always a chance for not fulfilling the contracted power due to the volatile nature of the renewable which creates an imbalance price in the system. In this situation, energy storage systems can alleviate the imbalance issues by supplying additional power to the electrical grid. This study proposes a two-phase scheduling technique for the optimum operation of a wind farm (WF)–pumped hydro storage (PHS)–solar-connected electric vehicle (EV) hybrid system to obtain more economic profit and revenue with a stable grid frequency. In the first phase, the energy level of PHS upper reservoirs has been scheduled to maintain the grid frequency with the presence of a wind farm. Along with the first phase, additionally solar-connected EVs are incorporated in the second phase to maximize the system profit further to get more economic benefit. A modified IEEE 30 bus system is used to effectively assess the aforesaid approach. MiPower software has been used to conduct this work. This proposed method has been compared with the existing method and got better results in all aspects.

      Abstract: Energy & Environment, Ahead of Print.
      Global warming has a direct relation with high temperature and management of heat stress in field crops is important for sustainable agriculture. Common buckwheat (Fagorpyrum esculentum Moench.) is an emerging pseudocereal and alternative food crop but shows sensitivity to heat stress. This two years (2017 and 2018) research was conducted to explore the physiological and biochemical mechanism of improving heat stress tolerance in buckwheat with foliar spray of different plant growth promoters (PGPs). The preoptimized levels of moringa leaf extract (MLE) of fresh (MFLE, 3%) and dried leaves (MDLE, 10%), ascorbic acid (AsA, 0.5 mM), a vitamin biosynthesized in plants and thiourea (TU, 10 mM), a synthetic growth bioregulator were foliar sprayed. Results revealed that growth attributes including shoot (34.61%) and root length (27.62%), dry weight (641.94% and 40.23%, respectively), stem diameter (52.05%), no. of roots per plant (27.27%), leaf area (24.86%), and no. of internodes per plant (16.17%) were impaired by heat stress. Similarly, antioxidants including leaf and root superoxide dismutase (17.11% and 21.43%), peroxidase (16.81% and 8.40%) and catalase (6.51% and 6.54%), respectively, were significantly affected by heat stress. PGPs spray alleviated heat damage by reducing the biosynthesis of leaf and root MDA and H2O2, and preferential induction of enzymatic antioxidants. PCA-biplot analysis showed that, amongst PGPs, MDLE was greatly effective in inducing antioxidant defense under heat stress. PCA and correlation matrix revealed that PGPs prompted induction of antioxidants was effective more in roots than leaves under heat stress. Conclusively, the induction of antioxidant defense with the PGPs especially with MLEs spray is the main mechanism, with great implications for heat tolerance in common buckwheat.

      Abstract: Energy & Environment, Ahead of Print.
      Recent decades have been marked by significant climatic changes and serious environmental damage. This phenomenon is growing more ubiquitous over time and across borders, majorly due to the alarming increase in global energy consumption. Considering the urgent need of reversing the current adverse environmental trends, this study contributes to elucidating the determinants shaping energy-saving behavior among the youth, the central agents of the future economy. We base our analysis on the eminent theory of planned behavior, with the addition of pro-environmental knowledge as a predictor and migration status as a moderator. Crucial findings have been drawn via a structural equation model approach from survey data on 1303 people aged 18 to 29. First, pro-environmental knowledge and subjective norms, through the media of attitude and perceived behavioral control, can predict energy-saving intentions and behavior among the youth. Second, migration status casts a widespread moderating effect across all translation routes, from knowledge to energy-saving behavior. This study is a serious attempt to enrich the relevant literature, further covering the population of the youth and the context of emerging nations. It also provides more in-depth insights into the psychological mechanism underlying the formulation of energy-saving behavior, with the issue of migration being considered. These findings highlight the importance of a migration-specific perspective in designing policies and subsequent programs geared toward energy conservation.

      Abstract: Energy & Environment, Ahead of Print.
      This research investigates the effects of income, total energy consumption (TEC), energy price index (EPI), crude oil price (COP), political risk index (PRI), and geopolitical risk (GPR) on environmental degradation. In this context, the study includes five Gulf Cooperation Council (GCC) countries, which are mainly oil-rich and have high fossil fuel energy consumption with increasing environmental degradation; considers monthly data from 2000/1 to 2021/12, and deploys novel quantile-based methods. The outcomes demonstrate that (i) an increase in income, TEC, and EPI stimulates environmental degradation in all GCC countries; (ii) PRI, COP, and GPR have mixed effects on environmental degradation; (iii) a causal effect from the regressors to CO2 emissions exists in all quantiles except for some middle (0.45–0.55) and higher quantiles (0.95); (iv) the power of effect and causal effect vary according to quantiles and countries; (v) the consistency of the results is validated based on robust model. The findings reveal that an increase in income, TEC, and EPI is generally harmful to the environment in the GCC countries; but, PRI, COP, and GPR have mixed effects. The results of novel quantile-based methods underline the significance of political stability and geopolitical risk effect as non-economic and non-energy factors on environment degradation by demonstrating quantile-based varying effects of the regressors on the environment in GCC countries. Accordingly, various policies, such as focusing on increasing political stability, benefitting from geopolitical risk as leverage, and enabling the transition to clean energy, are discussed.

      Abstract: Energy & Environment, Ahead of Print.
      This article considers a two-echelon supply chain consisting of one large-size supplier and one small-size manufacturer. The supplier wholesales raw materials to the manufacturer who processes them into final products and sells them to consumers. The supplier also engages in Cournot competition with the manufacturer by producing its product and direct selling to consumers. In addition, as an energy service company, the supplier may choose low-carbon production for its product and may help the manufacturer to achieve low-carbon production by providing energy performance contracting services to the manufacturer. We investigate whom the supplier should provide energy performance contracting services to and analyze the impact of the unit matching cost and the investment cost coefficient in implementing the energy performance contracting project on the optimal decisions and profits for the two members. The results show that when the investment cost coefficient is not high, the supplier prefers to provide energy performance contracting services to the manufacturer under a low matching cost and to the two members under a high matching cost. However, the manufacturer prefers to enjoy energy performance contracting services for itself regardless of the matching cost. With the increasing investment cost coefficient, the supplier changes the decision to prefer to provide energy performance contracting services for itself. In such case, the manufacturer also prefers to not accept energy performance contracting services, so the two supply chain members’ profits are highest.

In contrast, research into the interplay between population, economic growth (GDP), renewable energy, nuclear energy, fossil fuels, and greenhouse gas (GHG) emissions has received comparatively little attention. Thus, the main motive of this exploration is to analyze the influence of population, economic growth, and various energy sources consumption on the selected South Asian economy's GHG emissions using the STIRPAT model. The period 1972–2021 is used to estimate results by considering cross-sectional dependence (CSD) and slope homogeneity (SH) tests, as well as second-generation unit root and cointegration tests. Due to the presence of SH, CSD, and mixed-order unit root problems, the cross-sectional autoregressive distributive lag (CS-ARDL) model has been used to estimate the value of selected variables. The impact of GDP and population is positive but insignificant for South Asian countries in the short run, but GDP is significant in the long run. The research also revealed that burning fossil fuels significantly contributes to atmospheric gas emissions level. In addition, renewable and nuclear energy play useful and substantial roles in reducing pollution in South Asian countries. Therefore, it is recommended that the economies of the South Asian countries maintain a uniform approach to economic policy to fully benefit from the advantages of increased green and safe energy production.

      Abstract: Energy & Environment, Ahead of Print.
      This study contributes to the existing body of knowledge by examining the nonlinear impact of remittance inflow on green growth. To analyze the short and long-run estimates, we have relied on the nonlinear autoregressive distributed lag and quantile autoregressive distributed lag models. The use of nonlinear autoregressive distributed lag and quantile autoregressive distributed lag models to analyze the impact of remittance inflow on green growth is an innovative approach that adds to the existing body of knowledge on this topic. The long-run results from the nonlinear autoregressive distributed lag suggest that a positive shock in remittance inflow improves green growth, while a negative shock reduces green growth. Moreover, foreign direct investment, research and development activities, environmental technology, and financial development encourage green growth. In the short run, the remittance inflow improves the green in the nonlinear model only, and foreign direct investment promotes green growth in linear and nonlinear models. The nonlinear quantile autoregressive distributed lag results show that, in the long run, green growth exhibits an asymmetric response to both positive and negative changes in remittance inflow, particularly at higher quantiles. Our findings will suggest appropriate policies to policymakers regarding the effective utilization of remittances to enhance green growth.

  • Energy regulation, energy innovation, and carbon intensity nexus in China:
           A nonlinear perspective

      Authors: Feng Yanzhe, Sana Ullah
      Abstract: Energy & Environment, Ahead of Print.
      Considering the role of energy regulations and innovations in reducing energy-driven emissions, our main objective is to scrutinize the influence of energy regulations and innovations on carbon intensity in China over the period 1991–2020. In contrast to the previous studies, the analysis also focuses on the asymmetry assumption. The scientific value added to this study lies in its innovative methods and empirical evidence. The autoregressive distributed lag model, both linear and nonlinear, is utilized in the research to examine the short- and long-run estimates. The linear model highlights that energy regulations, energy innovations, and human capital reduce carbon intensity in the long run, while per capita income and financial development escalate it. However, only energy regulations and human capital help reduce carbon intensity in the short term. In the nonlinear models, the positive shock in environmental regulations reduces carbon intensity in short and long run. Conversely, the positive shock in energy innovations reduces carbon intensity in the long run. Negative shocks in energy regulations and innovations have a statistically insignificant impact on carbon intensity in both the short and long term. In addition, per capita income and financial development only increase carbon intensity in the long run, while human capital reduces carbon intensity in the short run. These findings advocate for implementing heavy energy taxes on firms and industries that rely heavily on fossil fuels. Increasing investment in green energy innovations is the need of the hour in lowering carbon intensity in China.

           with fulvic acid complex

      Authors: Köntös Zoltán
      Abstract: Energy & Environment, Ahead of Print.
      Increasing levels of carbon dioxide (CO2) due to natural and anthropogenic activities have led to alarming concerns of global warming. Photocatalytic conversion of CO2 to formic acid (FA) is speculated to provide a long-term solution for CO2 remediation and the production of green energy. Herein, we report the conversion method of CO2 to FA using water, light, and organic RRR catalyst at room temperature in a photocatalytic RK-X reactor. A total of seven experiments were conducted and observed to study the effectiveness of the reaction. The experiments achieved 8.47 g/L of FA concentrate. This photocatalytic conversion of CO2 into FA represents a promising approach to addressing global warming and providing carbon negative hydrogen as an answer to fossil fuel problems. Another possible application of this study is to provide sustainable energy on Mars, where water, light, and CO2 are all available for the reaction.

      Abstract: Energy & Environment, Ahead of Print.
      The dynamic stochastic effects regressions on population, affluence, and technology model used in this study reveals the nonlinear effects of urbanization routes on CO2 emissions in China, India, Indonesia, the United States, and Brazil during 1970–2020, using dynamic seemingly unrelated regression, dynamic ordinary least square, and fully modified ordinary least square techniques. The empirical analysis shows that urbanization and the proportion of small cities contribute significantly to CO2 emissions, while the square of urbanization and the square of the proportion of small cities significantly reduce CO2 emissions, thus supporting the inverted U-shaped relationship for the selected countries. However, the effect of the proportion of large cities significantly reduces CO2 emissions, while the square of the proportion of large cities significantly promotes CO2 emissions, supporting a U-shaped relationship for specific countries. Gross domestic product, industrial development, and transport infrastructure contribute significantly to carbon emissions, while renewable energy generation significantly reduces carbon emissions. The country-level augmented mean group estimator in the analysis supports an inverted U-shaped relationship between urbanization and carbon emissions and a U-shaped relationship between the proportion of large cities and carbon emissions in all selected countries. There is also an inverted U-shaped relationship between the proportion of small cities and carbon emissions in China, India, Indonesia, and Brazil. The causality test results acknowledge bidirectional causality between urbanization and carbon dioxide emissions; between urbanization squared and carbon dioxide emissions; between the proportion of the largest cities and carbon dioxide emissions, and between renewable energy and carbon dioxide emissions. This study recommends renewable energy options, green urban infrastructure, and digital technologies to improve the environmental quality of urban areas.

      Authors: Amanullah Bughio, Ying Teng, Raza Ali Tunio, Ghansham Das, Rizwan Jamali, Rashid Usman Shar
      Abstract: Energy & Environment, Ahead of Print.
      We propose a vector error correction model to explore the causal correlation between green finance, economic growth, and renewable energy consumption from both short- and long-run perspectives to empirically evaluate the efficacy of green finance policies. Based on time-series data from 2000 to 2020, we use the unit root test method to examine time-varying trends and cointegration for time-series data. We find that renewable energy consumption has a negative relationship with emissions but green finance is positively correlated with economic growth. Green finance is the driving factor behind the increasing utilization of renewable energy in China. CO2 emissions per unit of GDP decreased by 1.077% for every 1% increase in green finance development. Although the share of renewable energy consumption increased by 1%, CO2 emissions per unit of GDP decreased by 0.55%. Therefore, green finance is significant in decreasing CO2 emissions; it has a negative impact on CO2 emissions and the renewable energy sector and must be addressed by financial policy, stability, and long-run sustainability. We categorized green finance, which refers to carbon finance innovations such as trusteeship, to improve market demand and eventually develop industries to expand the number of emission-control industries.

  • SDGs and fictional energy utopias: Gauging sustainable energy transitions
           against Ecotopia (1975) and The Ministry for the Future (2020)

    • Free pre-print version: Loading...

      Authors: Daniel Wuebben, Roman Meinhold, Giovanni Frigo
      Abstract: Energy & Environment, Ahead of Print.
      Strategic narratives about the transition to sustainable energy systems, including those influenced by the United Nations’ sustainable development goals (SDGs), frequently incorporate utopian elements. These ambitious targets encapsulate future-oriented visions and postulate implications of technological advancements; they also often underrepresent or even bypass the multifaceted nature of socioeconomic diversities, planetary constraints, and persistent energy disputes. The genre of utopian science fiction can offer a valuable heuristic to elucidate the heterogeneous and occasionally unsatisfactory projections that emerge from the SDGs. Two seminal novels—Ernest Callenbach’s Ecotopia (1975) and Kim Stanley Robinson’s The Ministry for the Future (2020)—which we classify as “fictional energy utopias” (FEUs), present incisive critiques of contemporary energy mechanisms and practices and envisage equitable, resilient, and robust renewable energy systems and socio-technical structures. Through an approach that combines narrative and discourse analyses, these literary works are juxtaposed with selected indicators of three SDGs. The ensuing study underscores the primacy of the topic of energy in policy and its concomitant narratives in fostering collective endeavors toward sustainable development. It also amplifies the pivotal interconnections between SDG 7 “Affordable and Clean Energy,” SDG 13 “Climate Action,” and SDG 16 “Peace, Justice, and Strong Institutions.” Employing FEUs to evaluate sustainability policies can substantially benefit researchers, policy architects, and public engagement coordinators by highlighting lacunae and limitations within prevailing strategic narratives and proposing potential enhancements to fortify their capacity to motivate collective action.

      Authors: Judith N. Mangeni, Diana Menya, James Mwitari, Matt Shupler, Rachel Anderson de Cuevas, Edna Sang, Eslaba Anabwani, Noel Sutton, Emily Nix, Sara Ronzi, Dan Pope, Elisa Puzzolo, Kwaku Poku Asante
      Abstract: Energy & Environment, Ahead of Print.
      Polluting fuels such as biomass and kerosene are used for cooking by approximately 85% of the population in sub-Saharan Africa (SSA) despite the well-known associated negative health effects. Many governments across SSA are aiming to scale up the use of liquefied petroleum gas (LPG), a cleaner-burning fuel in terms of black carbon and fine particulate matter emissions, to promote public health and protect the environment by reducing deforestation. In Kenya, the government has been promoting rapid scale-up of LPG as a household fuel by zero rating it. A census survey was administered to over 2000 households in a peri-urban and rural sub-county of Uasin Gishu County to determine cooking characteristics and factors associated with the primary cooking fuel (biomass versus LPG). We found that the majority 72% (n = 1619) of the households mainly use biomass as a primary fuel (86% wood, 12% charcoal, 1.5% wood chips, and 1% kerosene) while about 28% (n = 629) use clean fuels (86.8% LPG, 12.9% biogas/solar, and 0.3% electricity). Peri-urban residents had up to 2.5 times increased odds of using LPG compared to those in the rural sub-county. Supply factors such as easy access to refills affect the number of days the LPG is used per week. Urbanization at sub-county leads to increases in use of LPG for cooking, irrespective of household-level SES. The Government is encouraged to enact policies that would increase the availability of LPG refills to rural communities hence reducing the time and transportation costs that are likely to affect access with consequent low usage.

      Abstract: Energy & Environment, Ahead of Print.
      The fact that scenarios of high unemployment potentially offer the opportunity for improved environmental sustainability remains a dilemma. In instances when environmental sustainability is triggered by increased unemployment, that poses a challenge in the simultaneous achievement of sustainable development goals (SDGs) 8 (decent work and economic growth) and 13 (climate action). On the basis of this concern, in this study, we examine whether a swap association exists between unemployment and environmental quality vis-à-vis the environmental Phillips curve (EPC) hypothesis for high-, upper, and lower middle-income (HUmLmI) economies (comprising both developed and developing countries) over the period 1990–2020. We used the novel dynamic autoregressive distributed lag simulation approach. From the findings, the EPC hypothesis is not valid in high-income (developed) economies in the short and long term. However, the validity of the EPC hypothesis was upheld in the upper and lower middle-income (developing) economies. This implies that the lack of decent work opportunities/high unemployment rates hampers environmental quality in high-income countries, promotes environmental quality in upper middle-income countries, and does not drive environmental quality in lower middle-income countries. In addition, economic growth and the use of fossil energy exacerbate environmental degradation. On the other hand, the consumption of renewable energy sources reduces environmental woes by −0.22, −0.54, and −1.15 in HUmLmI countries, respectively. This shows that renewable energy sources adapt to the environmental sustainability motive. These results imply that policy instruments to drive SDGs 8 and 13 in these income-categorized economies should be case specific rather than taking a unilateral policy approach.

      Authors: Xiaofeng Xu, Xiangyu Chen, Yunfei Liu, Nuozhou Huang
      Abstract: Energy & Environment, Ahead of Print.
      To achieve the goals of carbon peaking by 2030 and carbon neutrality by 2060, the Chinese government must reduce fossil energy consumption, stimulate the extraction of unconventional natural gas such as shale gas, and construct a green, low-carbon cycle economic development system. This study investigates the impact of government subsidies on shale gas companies’ research and development (R&D) inputs and innovation performance from multiple perspectives, including internal and external environments and the nature of the companies. The sample consists of Chinese shale gas companies listed between 2013 and 2019. The findings were as follows. First, the investment made by shale gas firms in R&D mediates the relationship between government subsidies and firm performance in technological innovation. Second, the contribution of government subsidies to innovation performance differs in different internal and external regulatory environments. Finally, the intensity of intellectual property protection (IPP) positively moderates the direct and mediating models of government subsidies and innovation performance. Accordingly, the government should increase its contributions to the shale gas industry, improve the regulatory mechanism for donations, and strengthen the protection of intellectual property rights for the R&D of new shale gas technologies.

      Abstract: Energy & Environment, Ahead of Print.
      The esterification reaction of oleic acid using heterogeneous catalysts can be a promising alternative for the production of biodiesel. This study proposed to obtain biodiesel from the esterification of oleic acid with the Zr-SBA-15 and SO42−/Zr-SBA-15 catalysts obtained by inserting Zr and subsequent sulphation of SBA-15 synthesized by the hydrothermal method. Zr-SBA-15 and SO42−/Zr-SBA-15 catalysts were initially synthesized by the wet impregnation method, followed by the sulphation process. The characterization of the catalysts was performed by: X-ray diffraction, thermogravimetric analysis, Fourier transform infrared spectroscopy, nitrogen adsorption/desorption, scanning electron microscopy, energy-dispersive X-ray spectroscopy and acidity test, with the aim of identifying the structure, composition and verification of the presence of acidic sites. The characterization results indicated that SBA-15 preserved the ordered hexagonal structure, after the incorporation of Zr, with the presence of nanoparticles of this metal dispersed on the surface and inside the microporous and mesoporous channels of the Zr-SBA-15 catalyst. After sulphation, the amount of acid sites increased and the ordered structure was maintained. For the Zr-SBA-15 and SO42−/Zr-SBA-15 catalysts, there was the formation of tetragonal and monoclinic structures of ZrO2. The catalytic activity was evaluated by the esterification reaction of oleic acid via the methyl route. Biodiesel obtained with SO42−/Zr-SBA-15 presented physico-chemical properties within the standards specified by ANP Resolution N° 798/2019 and a better yield of 80.7%. SBA-15 did not show catalytic activity for the oleic acid esterification reaction under the reaction conditions of this study.

      Abstract: Energy & Environment, Ahead of Print.
      A more comprehensive understanding of the impact of renewable energy on carbon efficiency could serve to achieve the win-win goal of carbon reduction and economic growth. This paper develops a data envelopment analysis model to measure carbon efficiency, analyses the non-linear, mediating and heterogeneous effects of renewable energy on carbon efficiency using panel data for 116 countries over the period 2005 to 2020. The results show that: (i) there is a certain difference in carbon efficiency among countries in different income groups. Specifically, the carbon efficiency of low-income and low-middle-income countries is generally in a low-efficiency state. (ii) There is an intermediary effect between renewable energy and carbon efficiency, which means that carbon efficiency can be indirectly improved by promoting technological innovation. (3) With the increase of income level, the positive effect of renewable energy on carbon efficiency is more effective. Finally, targeted policy recommendations are proposed.

      Abstract: Energy & Environment, Ahead of Print.
      With the ongoing expansion of global economic activities, environmental degradation has emerged as a progressively severe challenge. The Sustainable Development Goals are significantly impacted by this issue, making it essential to establish a symbiotic relationship between economic development and environmental protection. In this context, an investigation into the efforts of the OECD to promote ecological protection assumes a critical role, given its prominent position as a leading economic cooperation organization. Therefore, we examine the relationship between economic efficiency, financial development, renewable energy, industrialization, and ecological footprint in 36 OECD countries from 1995 to 2018. An empirical analysis employing the fully modified Ordinary Least Square technique reveals an inverted U-shaped curve relationship between economic efficiency and ecological footprint, supporting the environmental Kuznets curve (EKC) hypothesis in OECD countries. Moreover, the research reveals that financial development and industrialization exacerbate environmental damage, while the advancement of renewable energy plays a pivotal role in controlling the ecological footprint and fostering environmental conservation. Furthermore, by introducing interaction terms, we find that financial development and renewable energy weaken the positive effect of economic efficiency on the ecological footprint, while industrialization reinforces it. Finally, the findings of the Dumitrescu-Hurlin panel causality analysis show that the causal relationship between all three variables, namely economic efficiency, financial development and renewable energy consumption, and ecological footprint is bidirectional. In contrast, the causal relationship between the degree of industrialization and ecological footprint is unidirectional. These empirical findings provide practical policy recommendations for fostering sustainable development in OECD countries and offers valuable insights and lessons that can inform the formulation of relevant policies in other countries and regions. Overall, this study not only innovatively enriches the theoretical content of the EKC hypothesis from the perspective of the relationship between economic efficiency and ecological footprint, but also has important practical guidance significance.

      Abstract: Energy & Environment, Ahead of Print.
      Climate change is increasing owing to the frequency and intensity of extreme weather events caused by greenhouse gas (GHG) emissions mainly due to anthropogenic activities. In recent years, many countries have set goals to decrease GHG emissions and achieve carbon neutrality while maintaining their economic situation. The purpose of this study is to determine the optimal policy for fossil fuels and renewable energy allocation, which could decrease GHG emissions and maintain the economic situation in Taiwan until 2030. The results show that renewable energy rapidly increased to 5.8 billion kWh, and natural gas increased to 54 million m3 when energy consumption was maintained for the values in 2020. Greenhouse gas emissions in 2030 are expected to decrease to 20% of the value in 2005. Finally, the Taiwanese government should consider the allocation of fossil fuels and renewable energy with linear growth in energy consumption and achieve the goals of carbon emission reduction.

      Abstract: Energy & Environment, Ahead of Print.
      Human activities are the primary source of energy consumption and CO2 emissions. Adopting low-carbon behaviors (LCBs) can effectively reduce carbon emissions, which in turn helps alleviate environmental problems. Previous research shows that low-carbon policies can promote LCBs, while an extensive understanding of the effects of multi-types of low-carbon policies on various LCBs needs to be verified. Analyses on influencing factors regarding LCBs are dominated before, and place attachment and low-carbon behavioral intention as the influencing factors of LCBs, their relationship with low-carbon policy and LCBs needs to be clarified. By taking a questionnaire survey of residents of Hangzhou, China, this study presents a conceptual framework capable of analyzing the relationship between three types of low-carbon policies, including information policy, economic policy, and administrative regulations, and two types of LCBs, including low-carbon consumption (LCCB) and travel (LCTB) behavior, considering the mediation effect of place attachment and low-carbon behavioral intention in a single structural equation model. The results illustrate that administrative regulations and information policy have a direct positive impact on LCCB, and information policy has the most significant influence. Economic policy and administrative regulations directly impact LCTB, and administrative regulations have the most significant influence. The influence of administrative regulations on LCTB is more excellent than on LCCB. Information policy indirectly affects two types of LCBs through the chain mediation effect of place attachment and low-carbon behavioral intention. The results should be helpful to low-carbon policymakers seeking to promote LCBs to consider the importance of place attachment and various low-carbon policies. Moreover, they enrich our understanding of the influencing mechanism of LCBs.

      Abstract: Energy & Environment, Ahead of Print.
      In this study, a new cavity shape was filled with an extension multi-walled carbon nanotubes-Fe2O3/H2O nanofluid under a constant magnetic field. The Darcy–Forchheimer model is used to account for the inertial impact of advection in the porous layer while maintaining the laminar and incompressible nature of the nanofluid flow. The dimensionless version of the governing equations is used to describe the issue and the finite element approach is used to resolve it. Through this complex geometry, various thermophysical factors such as Rayleigh number [math], Hartmann number [math], and nanoparticle concentration are considered [math]. The porous layer's numerous characteristics are also explored. For example, its porosity [math] and Darcy number [math], which indicates the permeability of the porous medium. The content of the hybrid nanofluid is considered to be Newtonian, stable, incompressible, and following a constant Prandtl number for the base fluid [math]. Calculations are made according to the finite element method. The results of this work are presented in terms of rheology, isotherms, entropy generation, and mean Nusselt numbers. They have demonstrated that increasing the Rayleigh and Darcy numbers improve heat transfer in the enclosure.

      Abstract: Energy & Environment, Ahead of Print.
      This study applies wavelet analysis to examine the interplay between treadmill of destruction theory and environmental Kuznets curve theory in G7 countries over the period 1970–2018. The results indicate that, in the short term, co-movement and causality exist between military expenditure and environmental pollution at different frequencies and times. Positive causality runs from military expenditure to environmental pollution in Italy, the United Kingdom, the United States, Canada, and Germany in different sub-periods. After adding economic growth as a control variable, positive causality runs from military expenditure to environmental pollution in Italy, the United Kingdom, Japan, the United States, Canada, and France in different sub-periods. Decision-makers can refer to the empirical results to consider the direction of policy and managerial implications at macroeconomic and microeconomic levels.

      Abstract: Energy & Environment, Ahead of Print.
      Since the discharge of carbon is one of the main causes for ongoing global warming issue and change in climate, most nations have committed to decarbonizing their economies at the COP26 summit. Thus, this investigation aims to explore the consequences of innovations in sustainable energy technologies on decarbonization in the 20 most innovative nations across the globe. In assessing the cause-and-effect relationship, we have used “Panel Non-linear Autoregressive Distributed Lag (P-NARDL)” technique. The findings demonstrated that the variables have a lasting relationship. The positive asymmetric shock in the innovations in sustainable energy technologies has a positive influence on the decarbonization of these nations, while the negative asymmetric effect is insignificant. According to the findings, clean energy negatively consequence on carbonization whereas growth in economy is favorably and considerably connected with it. The findings demonstrate that there is bidirectional causation between all variables under investigation, with the exception of the unidirectional causality flows from the usage of sustainable energy technology and emissions of CO2. In a global context, this research suggests that government should identify the roles of new sustainable energy technologies by reforming patenting regulations to rectify the environmental damages.

      Abstract: Energy & Environment, Ahead of Print.
      Carbon emissions trading scheme (ETS) is a market-based measure to reduce carbon emissions. Evaluating the impact of carbon ETS on total factor carbon emissions performance (TFCEP) is of great significance to carbon emissions reduction and high-quality economic development in China. However, whether China's carbon ETS can improve TFCEP remains to be answered. Using the difference-in-differences model, super-efficient Slacks-based measure method and Malmquist–Luenberger index, this study evaluates the impact of carbon ETS on TFCEP and decomposition items of TFCEP based on the data during 2003–2017. Then, the heterogeneity effect of marketization and environmental enforcement are analyzed. The influencing mechanisms are tested from the perspective of industrial structure and green innovation and the moderating effect of carbon price and trading volume is also examined. The results show that carbon ETS could significantly improve TFCEP, and mainly improve the two decomposition items of efficiency change and scale technological change. Heterogeneity analyses show that the positive impact is more significant in cities with high levels of marketization and stricter environmental enforcement. Mechanism analyses suggest that carbon ETS could improve TFCEP by promoting industrial structure and green innovation. In particular, carbon prices and trading volume are confirmed to enhance the role of carbon ETS in promoting TFCEP. The results provide a new reference for Chinese government to use the market-based tool to reduce carbon emissions while maintaining economic growth.

      Abstract: Energy & Environment, Ahead of Print.
      In this research, an experimental and computational analysis of a novel hybrid vertical axis wind turbine (VAWT) arrangement has been performed. We suggest an innovative VAWT design that has a high power coefficient and self-starting capability. The inner side of the proposed hybrid system has been integrated with the H-rotor turbine with cambered blades, which demonstrates strong self-starting capabilities at various azimuths. Three NACA0018 airfoil blades are mounted on the outside of the proposed hybrid wind turbine, while three DU 06-W-200 airfoil blades are installed on the inside. Based on a similarity analysis, a scaled-down model was developed, and performance characteristics such as the output power, power coefficient ([math]), dynamic torque coefficient ([math]), and static torque coefficient ([math]) were determined. An existing hybrid VAWT and a typical H-rotor Darrieus design were also examined for comparison. The highest [math] for the proposed hybrid design was found to be 0.486 at a tip speed ratio (TSR) of 3, while the H-rotor Darrieus’ maximum value was 0.42 at a TSR of 2.62 and the existing hybrid VAWT’s value was 0.41 at a TSR of 2.5. Positive [math] values at all azimuths demonstrate that the proposed hybrid wind turbine can start entirely on its own. In comparison to the existing H-rotor and hybrid VAWT, this novel hybrid system has shown enhanced performance parameters ([math], [math], [math], output power) by around 11%–13% over a wide range of wind speeds.

      Authors: Muhlis Can, Daniel Balsalobre-Lorente, Festus Fatai Adedoyin, Mehmet Mercan
      Abstract: Energy & Environment, Ahead of Print.
      This research attempts to explore the scale (trade openness), composition (export concentration) and technique effect (economic complexity) of international trade on energy use in the sample of G7 nations over the period 1970 and 2020 separately. To do that, we build up three empirical models based on the regression on population, affluence and technology approach. The analysis outcomes indicated a positive long-run link between per capita income, urbanization, trade openness, export concentration, economic complexity and energy use across the three models. The outcomes obtained from long-run estimations provide evidence that economic complexity and export concentration decreases energy consumption. Besides, empirical findings show that trade openness boosts energy use. Based on the detailed empirical research, the direction for the policy is that they should harness more strength on energy conservation by increasing the composition and technical effects of international trade. They should also focus on improving the countries’ economic freedom (trade openness) while maintaining energy consumption at a lower rate.

      Abstract: Energy & Environment, Ahead of Print.
      The rapid growth experienced by the Gulf Council countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates) has placed significant strain on their ecological footprint due to extensive energy consumption. Consequently, it becomes necessary to examine the factors contributing to the high ecological footprint and explore potential solutions for its reduction. This study aims to analyze the key factors influencing the ecological footprint in the GCC countries from 1995 to 2020. Through an extensive review of existing literature, it is evident that economic growth, urbanization, and trade can disturb ecological balance, while environmental technology and renewable energy offer potential remedies for environmental challenges. Thus, these variables have been selected as independent factors for investigation. The results obtained from advanced panel techniques emphasize the significance of adopting environmental technologies and increasing the utilization of renewable energy sources in order to decrease the ecological footprint. Conversely, economic growth, urbanization, and trade are identified as crucial drivers of environmental degradation. Considering that the GCC countries heavily rely on oil and petroleum exports, as well as non-renewable energy sources for their economic activities, the positive relationship between economic growth and trade is to be expected. The results propose multifold recommendations: (i) providing incentives for renewable energy and (ii) prioritizing the implementation of clean technology over traditional technologies.

      Authors: Jie Wu, Ruizeng Zhao, Jiasen Sun
      Abstract: Energy & Environment, Ahead of Print.
      Urban agglomerations are significant contributors of greenhouse gases, and their transition towards low-carbon development will aid in achieving China's carbon neutrality objective. This study provides a decoupling index that assesses the level of separation between economic development and carbon emissions in five national urban agglomerations. In addition, the double fixed-effect STIRPAT and mediation effect models are utilized to test the impact factors and potential mechanisms of carbon emission efficiency (CEE). Results show that urban agglomerations are in a state of weak decoupling, yet achieving strong decoupling poses a challenge. The CEE is significantly varied across different regions and remains inefficient overall. The urban agglomeration with the highest CEE is the Pearl River Delta, with an average of 0.70. Moreover, the industrial structure represents a significant mediating effect in the relationship between economic growth and CEE. Technological innovation, opening up level, foreign direct investment, fiscal intervention and energy intensity negatively impact CEE. Finally, this paper proposes several recommendations.

      Authors: Chaoyu Zheng, Benhong Peng, Xuan Zhao, Guo Wei, Anxia Wan, Mu Yue
      Abstract: Energy & Environment, Ahead of Print.
      Massive power batteries (PBs) are crucial to new energy vehicle enterprises. Due to Extended Producer Responsibility (EPR), the third-party reverse logistics provider selection(3PRLPs) process has become an important decision to save cost. This paper uses an innovative combination of qualitative analysis and quantitative data integration to address the PB 3PRLPs problem by using Failure Modes and Effects Analysis (FMEA) and fuzzy evidential reasoning (FER). Firstly, the possible failures and potential effects in the PB 3PRLPs are identified by the FMEA to determine criteria and importance grades. Subsequently, AHP is utilized to calculate the criteria weight based on the importance of grades. FER is creatively applied to address the intersection of assessment grades and allocate the belief degree (BD) of the interaction to fuse heterogeneous data. Additionally, sensitivity analysis is done to look into the stability of the sequencing. Compared with other methods, the proposed method not only solves the subjectivity of AHP weighting but also manipulates probabilistic and fuzzy uncertainties for multi-criteria decision-making (MCDM). This method is useful in quantitatively analyzing the 3PRLPs problem and in providing auxiliary decision support for enterprises.

      Abstract: Energy & Environment, Ahead of Print.
      The unceasing ravaging effects of global warming have made the world rethink the choice of energy consumption, with policymakers pushing for an unconditional transition to sustainable energy believed to be eco-friendly. Although studies have emerged with a view to unravel the path to global environmental sustainability, the paths of biofuels remain scantly investigated. Hence, this study presented the maiden empirical support for the aggregated and disaggregated impacts of biofuels on environmental sustainability in five top biofuel-abundant economies (Brazil, China, Germany, Indonesia, and the United States) from 1995 to 2019. The papers add to the existing knowledge by considering the roles of green technological innovation (proxied by environmental-related technologies), affluence, green finance, population and coal in a novel STIRPAT framework. The stated model is empirically verified based on recent techniques encompassing CS-ARDL, CCEMG, AMG, and MMQR. The empirical results uncover that both effects of biofuels substantially moderate carbon emissions, thus paving the way for environmental sustainability. Besides, environmental-related technologies and green finance significantly mitigate carbon emissions, whereas affluence, population, and coal positively drive carbon emissions. The empirical regularity of the main estimators is confirmed based on the feedback from MMQR which uphold the validity of biofuels in mitigating carbon emissions at different quantiles. The outcomes of the causality analysis uncover unidirectional, bidirectional and non-causal nexuses. Policy insights that promote sustainable exploration of biofuels for achieving a carbon-neutral environment are exposited following the findings.

      Abstract: Energy & Environment, Ahead of Print.
      The release of greenhouse gases (GHG) is acknowledged as a serious hazard that fuels climate change (CC). The Middle East and North Africa (MENA) countries face particular environmental challenges due to its contribution to carbon dioxide emissions (CO2). There is, however, a scarcity of literature about the region's environmental challenges, despite its vulnerability to the consequences of CC. Therefore, the purpose of this research is to look at various solutions to the CC issue in the MENA area, that is, energy efficiency (EE), economic development, urbanization, fossil fuel (FF) usage, and renewable energies (RE). Further, the study seeks to evaluate CO2 emissions in the region by establishing a RE index. By applying the fresh technique known as the cross-sectional autoregressive distributed lag estimator to panel data for 18 MENA countries from 1990 to 2019, this study quantifies the impact of these variables on CO2 emissions. The findings reveal that the explanatory variables’ significance varies across regional panel clusters, with economic growth having a significantly positive effect on CO2 emissions in the long run. Moreover, the study rejects the Environmental Kuznets Curve hypothesis validation and highlights the importance of EE in boosting environmental quality in the long and short runs. Additionally, the outcomes suggest that RE contributes to reducing CO2 emissions, while the urbanization level and FF consumption adopted by MENA countries do not improve their environment. Thus, mitigating the negative consequences of CC in the MENA area necessitates encouraging EE and lobbying for a shift from FF to RE sources.

      Authors: Tingting Liu, Weijiang Liu, Min Liu, Yangyang Li
      Abstract: Energy & Environment, Ahead of Print.
      Resource and carbon tax should be taken seriously as typical price control policies to address the dilemma between economic development and carbon emissions in developing countries. Therefore, based on China, we construct a dynamic CGE model to evaluate the carbon emission reduction and economic effects of a single tax policy (resource tax or carbon tax) versus their combination. The simulation results demonstrate that the carbon tax policy is superior to the resource tax-increasing policy under a single tax policy. Specifically, it is hard to meet the autonomous national contribution target of peaking carbon by 2030 only by raising the resource tax, and the economic loss is relatively heavy. The setting of the initial carbon tax will affect the carbon peak time and total carbon emissions. When the initial carbon tax is 25 yuan/tonne, carbon emissions will peak in 2029. A combined tax policy is preferable to a single carbon tax policy. The combination of gradually increasing the carbon tax rate and lowering the resource tax rate can effectively reduce economic losses, achieve a carbon peak and promote the joint development of the environment and economy.

      Abstract: Energy & Environment, Ahead of Print.
      Ecological problems and environmental problems have become more and more frequent, constantly sounding the alarm for people, seriously threatening the safety of people's lives and even survival. The construction of ecological culture has become an essential part of modern society and a vital wealth. Therefore, it is urgent to organize the study of the relevant concepts and theories of ecological construction, explain and solve the problems encountered in practice, and guide people to make scientific judgments. The main purpose of this article is to study the structure of ecological civilization from the perspective of Marxist ecological view. By analyzing ecological and environmental issues, following the principles of ecological civilization construction, adopting appropriate means, and relying on an indicator system for evaluation. This article constructs a comprehensive indicator system for the level of ecological environment protection, and analyzes the global spatial autocorrelation and local spatial autocorrelation of the comprehensive indicators. Research shows that urbanization construction and energy efficiency protection are still in a moderate imbalance state. Due to the lag of urbanization construction in the process of ecological environment protection, the two are in a low coordination state. How to combine Marxist ecological views with specific practices in China and effectively promote the process of ecological civilization construction in China still requires in-depth consideration.

      Authors: Usenobong Akpan, Ukpai Kama
      Abstract: Energy & Environment, Ahead of Print.
      In this paper, we introduce a new innovation into the institutions and environmental degradation nexus debate, by placing emphasis on institutional quality (good or poor) in the modelling framework, a clear departure from the existing literature that makes no such distinctions when using institutions to investigate the nexus. Using a panel of 163 countries, and applying a system generalised method of moment technique, we obtained robust evidence that the quality of institutions really matters in protecting the environment. In particular, we found that countries with strong institutions could significantly reduce environmental pollution by limiting fossil fuel consumption, while those with poor institutions would worsen the situation. Countries with strong institutions were also found to be able to curtail environmental problems in densely populated cities than those with weak institutions. The policy implications arising from the study are clear – strengthening the quality of domestic institutions that relate to environmental policy formulation and regulation, is critical to delivering a cleaner environment.

      Authors: Zongsen Zou, Yu Zhang, Xindi Liu, Xin Li, Meng Wang
      Abstract: Energy & Environment, Ahead of Print.
      Non-renewable energy fosters economic growth, whilst simultaneously it serves as the primary source of carbon dioxide (CO2) emissions. Using data from the world's three major carbon emitters over the period 1980–2020, this paper adopts the non-linear autoregressive distributed lag (NARDL) approach to explore the dynamic nexus between energy consumption, economic growth and CO2 emissions. The results reveal that energy consumption matters for economic growth. From a short-term perspective, an increase in oil consumption positively impacts economic growth in the United States and India, whereas a negative shock solely affects China's economic growth. Regarding coal consumption, a positive shock only affects the US's economic growth, while China and India are more likely to be affected by a negative consumption shock. In the long run, the nexus between oil consumption and economic growth exhibits a similar asymmetric pattern in China and the United States. Concerning the effect of coal consumption on economic growth, only negative shocks count for China and positive shocks for the United States. The findings also identify various patterns of energy consumption on CO2 emissions. An increase in oil consumption, whether from a short- or long-run perspective, increases CO2 emissions in all three countries, while a decrease in oil consumption only mitigates CO2 emissions in China and the United States. There are more complicated patterns to the role of coal consumption in CO2 emissions. The results vary significantly from country to country; however, energy consumption has generally promoted economic growth as well as resulted in environmental issues that cannot be disregarded.

      Abstract: Energy & Environment, Ahead of Print.
      This work aims to explore the impact of intellectual property income (a guarantee for promoting technological advance) on energy efficiency (indicating the technological advance) considering the mediation role of trade openness. To this end, this article uses the available data of 50 countries from 2000 to 2019 to study the influence of intellectual property income and trade openness. The Fully Modified Ordinary Least Square and Dynamic Ordinary Least Square methods are applied in this article to study the long-term relationship between different variables. The empirical results show that there is a mediation effect between intellectual property income and energy intensity. In other words, intellectual property income can not only directly affect energy intensity, but also indirectly affect energy intensity through trade openness. Fully considering the impact of regional heterogeneity, the countries are divided into high-income (HI) countries and middle-income (MI) countries. The results indicate there are noticeable regional differences in the impact of intellectual property income on energy intensity via the mediation effect of trade openness. The improvement of intellectual property income and trade openness benefits the HI countries most, but not for MI countries. Targeted policy implications are proposed to enable a reduction in energy intensity for countries at different income levels.

      Abstract: Energy & Environment, Ahead of Print.
      With global low-carbon development, green innovation has becoming a key factor for countries to obtain and maintain core competitive advantages. However, the division of scientific research resources often fails to meet the requirements of economic development. Therefore, regional integration cooperation has become an inevitable choice for innovation and development. However, the effect of the impact, direction, and interaction of regional integration policies on green innovation decision-making remains uncertain. To study the synergistic development mechanism between the two, this study constructs a two-layer network model that includes the decision and influence layers and uses a graph neural network model to map the relationship between the two-layer networks. With the help of opinion dynamics model and public goods game model, we draw the following conclusions. (1) Limited communication between regions can encourage all parties to adopt active green innovation strategies. However, excessive communication can lead to disunity of opinions among all parties, which may not be conducive to green innovation and result in an increase in free-rider behavior. (2) Regional integration development can effectively prompt all parties to choose active green innovation strategies. (3) Increasing the breadth of regional integration cooperation is more effective in promoting the active participation of all parties in green innovation, compared to increasing the depth of regional integration cooperation. This study provides theoretical support for decision-making in regional integration and green innovation development.

      Abstract: Energy & Environment, Ahead of Print.
      Under the banner of sustainable transportation, fuel cell hybrid electric vehicles (FC-HEVs) have become a matter of fascination in today's ever-growing need to save fossil fuels and reduce greenhouse gas emissions, addressing the 3Es challenges (efficiency, economy, and environment). However, one of the most pressing issues at the moment is determining how to incorporate the optimal sizing and energy management strategy (EMS) into FC-HEVs. In this regard, this article presents an integrated approach for optimal sizing as well as a new energy strategy for the design of FC-HEVs. To minimize the decision variables, including operating cost, fuel consumption, and component weight, an in-house optimization MATLAB code with a Multi-Objective Particle Swarm Optimization algorithm was developed. Four energy cases were tested under ARTEMIS and NEDC driving cycles for simulation, and their influence on the key decision variables was also investigated. The results show that using a battery pack with a supercapacitor reduces fuel consumption by 19% and 30.3% in both driving cycles, while decreasing the maximum output power of the fuel cell. It should be noted that hybrid energy sources have the potential to improve vehicle performance.

      Abstract: Energy & Environment, Ahead of Print.
      The Chinese authorities firmly encourage the use of electric cars to decrease global pollution and fossil fuel consumption (electric vehicles). Nevertheless, research aimed at determining customers’ switching intentions toward electric vehicles and pro-environmental behavior are scarce in the country. The purpose of this study is to fill the knowledge gap by scrutinizing the linkage among general environmental knowledge, environmental concern, eco-label knowledge, eco-label attitude (ATT), switching intentions(SIN), and pro-environmental behavior that might affect customers’ SIN and PEB in the Chinese context. The present research has additionally improved the theoretical foundation of the Theory of Planned Behavior by adding three new aspects in along with the ongoing customers’ motive elements (eco-label knowledge, general environmental knowledge, and ATT). In a survey, 549 electric vehicle users in China were polled and their data were analyzed. The structural equation modeling method is used to assess theories that have been put forth. According to empirical evidence, general environmental knowledge, environmental concern, and eco-label knowledge have a favorable and substantial impact on ATT. In a similar vein, ATT has a positive impact on consumers’ SIN and PEB. The research adds to the field of study on renewable buying behavior and offers crucial and practical future paths for researchers and professionals.

      Abstract: Energy & Environment, Ahead of Print.
      The environmental Kuznets curve (EKC) is a widely tested hypothesis in the environmental economics literature. It explains the dynamics between economic growth and environmental degradation. This study conducts a bibliometric analysis for the past three decades (1994–2021) that contributes to the intellectual structure and knowledge progress of the EKC hypothesis using descriptive analysis and networking analysis. The descriptive analysis comprises publication trends, language, publishers, Web of Science category and research areas, and citation analysis. Meanwhile, networking analysis includes keyword co-occurrence analysis, co-authorship analysis and co-citation analysis. The findings of the descriptive analysis reveal that the number of publications in the EKC hypothesis has gradually increased over the years. The most productive publishers are Elsevier and Springer Nature. Researchers from China and Turkey tend to be the most prolific authors, with the highest number of citations, co-authorships and co-citations. According to the network analysis, the main keywords appearing in the EKC studies are economic growth, CO2 emissions, energy consumption, China, renewable energy and financial development, which is also supported by the most frequently used keyword plus and its clusters. Based on our findings, we have proposed several policy recommendations from the keyword analysis that could foster economic development and improve environmental quality simultaneously. From the emerging trends of EKC, new directions for future research are also proposed.

      Abstract: Energy & Environment, Ahead of Print.
      In recent years, electricity systems have been undergoing rapid renewable energy transitions. This has introduced myriad challenges, namely, matching variability in both supply and demand sides, low plant load factors, resource constraints, etc. Managing these challenges requires effective demand-side solutions. Therefore, demand response (DR) approaches become relevant and essential in better-performing supply- and demand-side planning and management. For this purpose, in this article, two scenarios representing different situations and needing different interventions are developed for future years to study the effectiveness of demand-side solutions in managing the adverse supply-side constraints through an optimization model. The two scenarios are (i) Demand Response in Constrained Electricity System and (ii) Demand Response in High Renewables Electricity System. The model results suggest that the optimization model is robust enough to achieve an optimal as well as desirable solutions for both scenarios and provide evidence for the effectiveness of DR in addressing such challenges. DR solutions, if implemented effectively, can alter and moderate load curves to achieve perfect balance with supply profiles that are affected by resource constraints or by high penetration of solar and wind energy resources.

      Abstract: Energy & Environment, Ahead of Print.
      Facts have proven that humanity has incurred a significant environmental cost in the process of gaining economic success due to a surge in carbon dioxide emissions. Nevertheless, if carbon emissions are not curbed at the same time, economic growth may be slowed or stopped completely. It is for this reason that OECD member countries have set out plans to cut emissions. For this reason, the current paper scrutinizes the consequence of renewable energy intake, nonrenewable energy usage, economic globalization and economic progress on environmental destruction among 28 OECD countries by means of data spanning 1990 to 2019 period. The augmented mean group heterogeneous panel model and the common correlated effects mean group regression technique revealed evidence of a positive and negative significant connection between economic progress, and square of economic progress and carbon emission respectively (thus justifying the presence of the reversed U-shaped curve hypothesis) for OECD countries. Moreover, both renewable energy intake and economic globalization reveal a destructive connection with environmental destruction while nonrenewable energy intake has positive significant relationship with the environment. It was also disclosed that renewable energy intensifies the environmental destruction reducing effect of globalization and negatively moderates the impact of economic progress on environmental destruction. On the basis of the findings, appropriate policy recommendations have been developed to assist these economies in their efforts to dissociate economic progress from environmental destruction.

      Abstract: Energy & Environment, Ahead of Print.
      The unwavering adverse effects of global warming continue to threaten the sustainability of the ecosystem and peaceful human coexistence. Efforts to resolve this ecological matter promulgate the interest in green policies, which the extant studies are yet to explore fully. Consequently, this study provides the first empirical evidence on the roles of green policies vectoring, green energy, green finance, and green innovation amidst eco-digitalization and urbanization on environmental sustainability captured by CO2 emissions, ecological footprint, and PM2.5 air pollutions in BRICS countries from 1995 to 2019. The study relies on the STIRPAT framework alongside second-generation estimators in providing the empirical evidence. Findings indicate that green energy, green finance, green innovation, and eco-digitalization promote environmental sustainability by reducing CO2 emissions, ecological footprint, and PM2.5 air pollutions. Conversely, urbanization and affluence deter environmental sustainability due to their inducing effects the highlighted pollutants. The distributional analysis based on quantile regression and country-level estimation based on fully modified ordinary least squares technique accentuates the empirical regularity of the main findings. Besides, the Granger causality reveals the presence of bidirectional and unidirectional causality relationships in the estimated model. Based on the findings, feasible policies that enhance sustainability of the BRICS environment are formulated.

           Evidence from a policy shock

      Authors: Sheng Liu, Xin Gu, Xiuying Chen
      Abstract: Energy & Environment, Ahead of Print.
      The ecological accountability reform is an emerging environmental regulatory tool used by transition economies to correct failures and deviations in the traditional central-local environmental governance mode. This paper applies the propensity score matching with difference-in-differences method to test the impact of the central environmental inspection, an ecological accountability mechanism, on the investment efficiency of enterprises. The results reveal that the central environmental inspection can improve the corporate investment efficiency by resisting the urge to over-investment. Furthermore, this policy can improve corporate investment efficiency by dual functions of the incentive effect of increasing R&D investment and the pushback effect of financial risk. After a series of robustness checks, the results remained reliable. Heterogeneity tests show that the effect gradually appears in regions that implemented policy lately or with re-inspection, indicating the necessity of establishing a long-term mechanism. What's more, the positive effect of the central environmental inspection on corporate investment efficiency will be more significant in SOEs, large companies, and companies in provinces with weak environmental regulations. To achieve carbon peaking and carbon neutrality goals, this paper provides implications for improving collaborative governance system of local environmental protection and strengthening the linkage of environmental regulation and enterprise investment.

      Abstract: Energy & Environment, Ahead of Print.
      The prior empirical studies indicate torusim sector as an engine of economic growth worldwide. However, the activities linked with the tourism industries create several environmental problems as they require massive energy consumption. This study empirically explores the influence of tourism sub-sectors, i.e., accommodation (ACC), travel (TSP), food and drinks services (FDS), and shopping and entertainment (SAE) on the environmental quality in China measured by different greenhouse gasses emission and air pollutants. The bound testing ARDL approach has been employed to analyze the relationships for the data from 2001 to 2019. We also account for globalization (GLBN), economic growth (RGDP), and energy consumption (ENG), to normalize the tourism-linked sub-sectors’ environmental effects. The findings revealed that greenhouse gas emissions, especially N2O and CH4, are highly caused by FDS activities related to tourism, whereas CO2 emission is mostly caused by the TSP sector in long-term. Likewise, FDS is the highest causing factor of air pollutants except for PM2.5, and the SAE sector is highly responsible for N2O and CH4 in long-term. Furthermore, all the tourism-related sub-sectors are positively affecting economic growth and energy consumption in long-term, while TSP and SAE sectors contribute higher to the energy consumption and economic growth, respectively. Surprisingly, globalization has been seen to be a significant cause of decreasing greenhouse gases and air pollutants. Finally, the causality analysis outcomes revealed that most of the tourism sub-sectors are significantly causing air pollutants and greenhouse gases. As evidenced by the empirical results, numerous policy measures are proposed for policy initiatives for China to promote its environmental quality.

      Authors: Shih-Chin Lee, Stanley Y. B. Huang
      Abstract: Energy & Environment, Ahead of Print.
      To examine how clean energy technology companies, achieve sustainable clean energy development, the present study proposes a new model that uses the upper echelons theory to describe how Chinese-specific environmentally responsible leadership (CERL) of chief executive officers (CEOs) influences a company's adoption of green innovation strategy (GIS) via the intermediary role of the environmental organizational citizenship behavior (EOCB) of top management teams (TMTs).The multilevel curve model is used to analyze a survey of 50 CEOs and 150 TMT members collected three times in 6 months, and the results of the analysis support all the hypotheses. The results have three important contributions to the energy and environment field. First, the present study is the first to propose CERL, and CERL can not only promote the development of environmental leadership in the Chinese environment but also achieve the goal of sustainable clean energy operations. Second, the present study employs a specific model to demonstrate how TMTs’ EOCB can transform companies’ strategic formulations into GIS through the CERL of CEOs. Finally, the present study addresses the cultural gap through CERL, so it makes a significant contribution to the energy and environment field from a cultural dimension.

  • Revisiting the impact of renewable energy on carbon emission in 130
           countries—The mediating effect of resource rental rents and human
           capital

      Abstract: Energy & Environment, Ahead of Print.
      More efficient use of renewable energy to reduce carbon emission requires a more comprehensive understanding of the impact of renewable energy on carbon emissions. To this end, this work investigates the linear and nonlinear relationship between renewable energy consumption and carbon emissions in 130 countries from the new perspective of resource capital factors (total natural resources rents) and human capital (human capital index). The results are given that from a global perspective, the increase in the proportion of renewable energy consumption can accelerate the reduction of per capita carbon emissions before reaching a particular threshold value of total natural resources rents. When a specific natural threshold value is reached, the increase in the proportion of renewable energy consumption will reduce the rate of per capita carbon emissions. Another interesting finding is that the greater the human factor, the lower the reduction rate of per capita carbon dioxide emissions. To explain the above phenomenon, all countries are divided into four different income levels for further heterogeneity research. When the threshold variables are different, the impact on carbon emissions in various income countries is heterogeneous, which is further analyzed in the article. Furthermore, a meaningful discovery shows that whether the threshold variable is natural or human factor, low-income countries benefit the most from the carbon reduction effect brought by the increase in the proportion of renewable energy consumption, followed by lower-middle income and upper-middle income countries, and the lowest is higher-income countries.

      Abstract: Energy & Environment, Ahead of Print.
      Improving the Yangtze River Economic Belt's industrial energy efficiency is not only an important measure to alleviate China's energy shortages but also a drive to promote green economic development. The Super-EBM model, Malmquist productivity index, exploratory spatial data analysis, and Spatial Dubin model are used in this article to investigate the spatial-temporal dynamic development characteristics and influencing factors of industrial energy efficiency in 108 cities of the Yangtze River Economic Belt from 2011 to 2020. The findings demonstrate that the industrial energy efficiency of the Yangtze River Economic Belt and its three urban agglomerations went through three stages, including the “oscillation period,” “stability period,” and “enhancement period,” and decreases from east to west in the spatial dimension. The Yangtze River Delta urban agglomeration has the highest industrial energy efficiency, followed by the Middle-reach Yangtze River urban agglomeration, and the Chengdu-Chongqing urban agglomeration is the lowest. Further, this article identifies seven influencing factors including government intervention, industrial structure, degree of openness, R&D investment, urbanization, economic development, and environmental regulation. This article provides suggestions for industrial energy efficiency improvement.

      Abstract: Energy & Environment, Ahead of Print.
      Environmental (E), social (S), and governance (G) concepts have become a global consensus. Therefore, exploring the motivation mechanism adopted by companies to carry out ESG practices to promote sustainable social and economic development is of far-reaching significance. This study investigated whether there was a peer effect in the ESG practices of A-share listed companies and explored its mechanism of action and economic consequences using the data of Chinese A-share listed companies from 2010 to 2021. The empirical results show that there is a significant regional and industry peer effect on the ESG practices of A-share listed companies, which still holds when the average stock trait return is used as the instrumental variable. Furthermore, the mechanism test indicates that the information learning motive and agency cost are potential reasons for the peer effect of ESG practices. On the one hand, followers with information disadvantages tend to imitate the ESG practices of leaders with information advantages, but the converse is invalid. On the other hand, a worse external information environment leads to a higher degree of uncertainty, while a higher agency cost leads to a stronger peer effect of ESG practices. Lastly, the peer effect of corporate ESG practices helps create corporate value and increases corporate risk-taking to some extent. This paper provides a new micro perspective for understanding the occurrence mechanism and economic consequences of ESG practices, as well as crucial empirical evidence for firms to make sustainable development investment decisions.

      This study investigates the impacts of industrial intelligence on the total factor energy productivity (TFEP) using extended STIRPAT and spatial moderation models for China's industrial sector. The results show that TFEP and industrial intelligence are both increasing, and industrial intelligence positively affects TFEP, for every 1% increase in industrial intelligence will lead to TFEP growth by 0.121% in the study area and 0.031% in surrounding areas. Environmental regulation, industrial upgrading, and advanced human capital all function as helpful moderators between industrial intelligence and TFEP, that is, for every 1% increase in environmental regulation, industrial upgrading, and advanced human capital, the growth of TFEP caused by industrial intelligence enhanced by 0.003%, 0.009%, and 0.022% in study area and 0.005%, 0.042%, and 0.054% in surrounding areas.

      Abstract: Energy & Environment, Ahead of Print.
      This study examines the impact of financial instability (FI) on environmental degradation (ED) along with economic growth (EG), foreign direct investment (FDI), and energy consumption (EC) in five South Asian economies from 1980 to 2021. The study uses a fixed-effect panel model and a two-step system GMM for robust outcomes. The empirical findings demonstrate that FI has a positive and significant effect on ED in South Asian economies. However, the impact of FI on ED varies across South Asian countries. Overall, the impacts of EG, FDI, and EG are positive and significant on ED in South Asia. The effects of EG, FDI, and EG are also heterogeneous for countries in South Asia. However, FDI reduces ED in Pakistan, Bangladesh, and India. Therefore, the study provides several policy recommendations to combat ED in the South Asian region.

      Abstract: Energy & Environment, Ahead of Print.
      This study examines the relationship between air pollution and daily mobility, focusing on daily bus and subway usage in Seoul using panel data with the fixed effects model. This study empirically examines the effect of air pollutant exposure on the daily moving population volume, including daily bus and subway usage in Seoul over 1271 days. The results show that people's sensitivity to particulate matter is complex. The most remarkable aspect of the results is that people are not sensitive to continuous pollutant levels, but to the comprehensive air-quality index (CAI). In addition, people's sensitivity is different depending on the moving distance and the means of transportation. Considering that CAI is defined by adopting the first air quality guidelines proposed by the World Health Organization (WHO) in 2005, these results explain how sensitive people are to the human health risks of particulate matter exposure recommended by the WHO. Our findings can be used as evidence to establish the new particulate matter standards and policies that can be strengthened by reflecting the recently updated WHO's air quality guidelines in 2021.

      Abstract: Energy & Environment, Ahead of Print.
      Ensuring effective forecasting of buildings' energy consumption is crucial in establishing a greater understanding and improvement of buildings' energy efficiency. In Singapore, domestic electricity usage in public residential buildings takes up a significant portion of the country's annual energy consumption. Having effective forecasting approaches is thus important in supporting relevant strategies and policy making. In this research, we proposed a hybrid approach that was based on a combination of building characteristics and urban landscape variables to predict residential housing electricity usage in Singapore. XGboost was also incorporated inside the hybrid approach as the preferred machine learning approach for energy consumption predictions. To demonstrate our proposed approach's predictive strength, the performance of our proposed hybrid machine learning approach was compared with two other models, Geographically Weighted Regression (GWR) model and the Random Forest (RF) model. Results showed that our proposed hybrid model had outperformed these abovementioned approaches with higher accuracy (r2 value of 0.9). The proposed approach had thus been effective in forecasting electricity consumption for public housing in Singapore, and it could also be utilised in other similar urban areas for future electricity consumption forecasting.

      Abstract: Energy & Environment, Ahead of Print.
      The role of green finance is to develop green industry mechanisms in areas including transportation, building, water preservation, clean energy production, storage, and distribution, which ultimately results in emissions and waste reduction, biodiversity habitat protection, and pollution control. Therefore, recognizing the significance of green finance, this research investigates the asymmetric role of green finance and clean energy in the reduction of carbon emissions along with economic growth, foreign direct investment, and urbanization as control antecedents using the econometric model of “non-linear autoregressive distributed lag (NARDL)” for the period 2000–2020 in ASEAN nations. According to the NARDL outcomes, green finance, and clean energy positive shock enhances the ecological quality and negative shocks harm environmental quality. In addition, economic growth, and urbanization contribute to harmful pollutants. Therefore, the results recommend ASEAN nations’ governments, environmentalists, and policymakers, devise strong financial mechanisms, and develop long-term green investment strategies to attract green finance and investment opportunities to bridge the gap in clean energy.

      Abstract: Energy & Environment, Ahead of Print.
      During the inhibition path of carbon emissions, the role of green finance is of increasing concerns, among which, green credit is regarded as crucial instrument. However, there exist insufficient empirical explorations on effects of green credit. Therefore, this study introduced intergovernmental panel on climate change method to calculate regional carbon emissions based on eight fossil fuels from 2008 to 2019 in China. Subsequently, spatial measurement, threshold regression, and intermediary model were further applied to examine how green credit may affect carbon emissions regarding the restraining effect, threshold effect, transmission mechanism, and spatial heterogeneity. The results show that: (1) green credit can effectively inhibited China's provincial carbon emissions although there existed regional inconsistency. (2) Appropriate levels of environmental regulation and marketization can enhance the repress effect of green credit. (3) Green credit can suppress provincial carbon emissions through optimizing the energy consumption structure, while there exists no intermediary effect of industrial structure upgrading during impact path. (4) Considering endogeneity, green credit can still significantly inhibit regional carbon emissions. These findings further enrich the current literature and provide references for policy design of constructing efficient carbon neutralization path.

      Abstract: Energy & Environment, Ahead of Print.
      This research seeks to combine a comprehensive analysis of the literature regarding energy efficiency and inverters with an analysis of a configuration of a hybrid energy system including a generator, an inverter and a battery. The inverter's power output is analyzed under the influence of different distribution functions during a robust modulation procedure for achieving optimum energy saving. The modulation is tested on two processing machines independently: (a) an electric discharge machine, and (b) an injection molding machine. Based on the research methodology, problem formulations and the conducted analysis, a novel research software called “Inverter Pro V1” was programmed to analyze the estimations and performance of inverters in an energy system. An optimal levelized cost of electricity was determined given certain systems design and operating hours, and a sensitivity analysis was undertaken that identified a range of energy savings. In the sensitivity and optimization analysis, interactions among the primary decision parameters including the system's capacity, operating time, energy saving, cost of energy and payback period are investigated. It is also found that for each system, the inverter modulation categories with the optimum payback period belong to a modulation of inverter designed according to the Sawtooth function with a 45% duty cycle and switching intervals of 0.35 s. By considering the operating hours of 12.5 h per day, and the calculated system's investment cost of €31,782.158, the optimum payback period is estimated to be 1.7729 year. The study results are to inform policy with regard to assisting sustainable electricity production.

      Abstract: Energy & Environment, Ahead of Print.
      The current COVID-19 pandemic was a huge shock, influencing a wide range of socioeconomic measures, including the environment. The issue of how the uncertainty caused by pandemics will influence environmental quality is critical. This research examines the nonlinear relationship between pandemic uncertainty and environmental quality across leading polluted emerging economies (China, India, Russia, Indonesia, Brazil, Mexico, Iran, Saudi Arabia, South Africa, and Turkey). Using data ranging from 1996 to 2020, a distinctive approach, ‘Quantile-on-Quantile’, is used. Greenhouse gas emissions (GHG) are adopted as a proxy for environmental quality. The outcomes analyze how pandemic uncertainty's quantiles influence the quantiles of GHG asymmetrically, giving an efficient paradigm for grasping the entire dependence structure. The findings show that pandemic uncertainty improves environmental quality by decreasing GHG in our sample economies at diverse quantiles. Higher levels of GHG (75th–90th quantiles) suggest a strong negative association between pandemic uncertainty and GHG in the majority of nations. The magnitude of the coefficients helps to explain why pandemic uncertainty has a significantly greater impact on GHG in Mexico and Turkey (with a coefficient size of −2) compared to Russia, India, and South Africa, where the effect is considerably smaller (with a coefficient size of −0.05). Furthermore, the rank of asymmetry in our chosen variables fluctuates by nation, underscoring the prominence of governments exercising caution and prudence while implementing pandemic-based uncertainty and environmental quality measures.

      Authors: Seonho Lee, Young-Kwon Park, Jechan Lee
      Abstract: Energy & Environment, Ahead of Print.
      A tremendous amount of plastic and tire waste is generated every day. Pyrolysis gives a sustainable plastic and tire waste management solution by transforming them into high-value carbonaceous materials (i.e., char). Char made from plastic or tire waste can be used as a modifier for asphalt binder (i.e., bitumen), in order to improve the properties and performance of base bitumen. In most cases, the char is produced from waste feedstock at ≤300°C, most likely due to the high volatile matter content in feedstock. These chars have been proven experimentally to enhance the deformation resistance, rutting resistance, stiffness, and elasticity of bitumen. The optimal dosage of char in the modification process is highly associated with the kind of waste feedstock and pyrolysis conditions under which the char is made. The present review highlights the promise of the char materials derived from plastic and tire waste for use in materials applied to civil and construction industries, which is aimed specifically at expanding the application of chars made from plastic and tire waste beyond their typical applications, such as in environmental remediation and catalysts.

Frontier research generally focuses on the impact of renewable energy development and technological innovation on environmental protection and neglects the inequality in renewable energy technology innovation. This paper constructs a renewable energy technology innovation inequality index and analyzes the impact of digital finance on renewable energy technology innovation inequality using panel data from 30 regions in China from 2011 to 2018. The study found that digital finance can alleviate inequality in renewable energy technology innovation. The mechanism test results show that digital finance can optimize green credit allocation, promote technology flow, and optimize energy consumption structure, thus reducing inequality in renewable energy technology innovation. Further analysis shows that the differences in local government governance, environmental regulation, financial supervision, marketization, digital divide, and renewable energy category affect the relationship between digital finance and inequality in renewable energy technology innovation. This paper clarifies the relationship between digital finance and inequality in renewable energy technology innovation and provides new ideas for renewable energy technology innovation.

      Abstract: Energy & Environment, Ahead of Print.
      This study investigates the impacts of economic policy uncertainty (EPU), energy consumption (EC), sustainable technological innovation (STI), and quality of governance on green growth (GG). Besides, it examines the moderating effect of STI and governance quality on the association between EPU and GG. It applies a Pooled Mean Group Autoregressive Distributed Lag estimator for 25 emerging economies for periods 1991–2019. For the robustness test, we utilize the asymptotic distribution of the Cross-section Augmented Distributed Lag to control for cross-sectional dependence concerns. We drive two indicators for GG by applying the principal component approach and directional distance function. The findings imply that STI and quality of governance have significant positive impacts on GG. However, EPU and EC adversely impact GG in emerging economies. Besides, quality of governance and STI positively moderate EPU's influence on GG, implying that countries with better quality of governance and promote STI mitigate the detrimental effects of high EPU on GG. Moreover, we run the causality analysis to investigate the causal relationship between target variables and GG. Policy suggestions are proposed based on the results.

      Abstract: Energy & Environment, Ahead of Print.
      In response to the coronavirus disease 2019 pandemic, the Chinese government implemented blockade measures in Hubei, which largely affected the emission of pollutants. This work is aimed to explore the effects of epidemics on pollutants at different temperatures in Hubei, China. We applied for a panel nonlinear model with autonomous search thresholds to explore this, using daily average temperature as a threshold variable, and PM2.5 set as the explained variable, and the cumulative number of confirmed coronavirus disease 2019 cases set as the explanatory variable. An empirical analysis was conducted by running the proposed model and using nine cities in China most impacted by the pandemic. The results show that there was a non-linear negative relationship between the cumulative number of confirmed coronavirus disease 2019 cases and PM2.5. A more detailed non-linear relationship between the two was uncovered by the proposed panel threshold regression model. When the temperature crosses the threshold value (12.5 °C and 20.5 °C) in sequence, the estimated value was −0.0688, −0.0934, and −0.1520 in that order. This means that this negative non-linear relationship increased with increasing temperature. This work helps to explore the effect of coronavirus disease 2019 on pollutions at different temperatures and provides a methodological reference to study their nonlinear relationship.

      Authors: Khalid Ahmed
      Abstract: Energy & Environment, Ahead of Print.
      Although globalization is widely credited for unprecedented global economic growth, it also bears responsibility for climate change. Today, the primary emphasis of contemporary research is to find ways that help to reduce climate change adversaries without compromising the globalization-led economic development agenda. Thus, this study takes the case of 12 emerging economies selected based on their emissions profile and vulnerability to climate change. Covering annual data from 1972 to 2018, this study accounts for globalization's economic, social, and political aspects and empirically tests their relationship with carbon footprints and energy demand in the panel countries. The results confirm the long-run equilibrium relationship among all the underlying variables and find that economic globalization significantly contributes to energy demand and carbon emissions. However, such an effect can be overcome through social globalization. Whereas political globalization reduces the energy demand but spurs carbon emissions. Our results rule out the ant-globalization narrative and support pro-globalization chronicles for sustainable development policy agenda in emerging economies. We suggest that the emerging countries that are mainly facing the decision dilemma to choose between sustainable economic growth and a sustainable environment, are better off if they equally integrate socially and politically with the global economy. Moreover, the model is checked for robustness using FMOLS and found validated. It warrants that the results are appropriate for policy control use.

      Authors: Abraham Ayobamiji Awosusi, Husam Rjoub, Mehmet Ağa, Ifeoma Prisca Onyenegecha
      Abstract: Energy & Environment, Ahead of Print.
      Boosting energy consumption, ensuring energy supply security, and mitigating emissions are critical global concerns, especially during the surge in energy prices, continuous expansion in income level and persistent economic integration with other countries, and climate change. The existing evidence on the determinant of renewable energy is still in its early stages; however, there is currently limited empirical evidence regarding the determinant of renewable energy in Australia. Therefore, this study probed into the effect of the asymmetric effect of economic globalization on renewable energy usage in Australia, which prior studies in the literature have neglected. The study employed carbon emissions, economic growth, and oil price as other regressors. The dataset for the period spanning from 1970 to 2018 was analyzed using the nonlinear autoregressive distributed lag. Evidence from the empirical analysis reported that the positive variation in economic globalization has a positive and significant effect on renewable energy, thus the rise in economic globalization promotes renewable energy. Meanwhile, the negative variation in economic globalization has a neutral impact on renewable energy. Furthermore, economic growth and oil price positively and significantly affect the usage of renewable energy in Australia. Moreover, carbon emissions have a negative and significant effect on renewable energy. Furthermore, the wavelets coherence was also for the robustness test, which reports positive co-movement between all regressors and renewable energy, except for CO2 emissions (negative co-movement). Economic globalization, economic growth, and CO2 emissions drive renewable energy, while renewable energy leads to oil prices in Australia. This study offers significant and crucial suggestions to policymakers in Australia, emphasizing the need to prioritize environmental sustainability and promote economic globalization to foster the growth of the clean and efficient energy sector.

      Authors: Shim Dongnyok, Hyunhong Choi, Kim Seung Wan
      Abstract: Energy & Environment, Ahead of Print.
      On the path to carbon neutrality by 2050, the expansion and improvement of high-voltage power transmission lines (HV-PTL) is a critical and unavoidable energy issue that may become a potential source of public conflict. However, the discussion on this issue in South Korea has been insufficient. In this study, we analyzed public attitudes toward HV-PTLs and classified people into subgroups based on their common characteristics using latent class models. In addition, we used the contingent valuation method to estimate the public's willingness to pay (WTP) for the conversion of overhead lines to underground cables, focusing on the differences among the identified subgroups. According to the empirical analysis, people in South Korea can be divided into four classes based on their perceived need for resident participation in the decision-making process, perceived health risk, and perceived property loss risk. According to the WTP analysis using the spike model, the estimated mean and median WTP values were KRW 4184 (USD 3.8) and KRW 2632 (USD 2.4) per household per month, respectively. In addition, we found a significant difference in WTP by class. Those who perceived HV-PTL as risky were less willing to pay for undergrounding projects compared with those whose perceived risk was relatively low. This study contributes to the understanding of academics and policymakers on the relationship between public attitudes toward HV-PTL and overhead to underground conversion.

  • The impact of green consumers on electric vehicle charging station
           diffusion based on complex network evolutionary game

      Authors: Feng Liu, Xingjun Huang, Longxiao Li
      Abstract: Energy & Environment, Ahead of Print.
      The disparity between the supply and demand for public charging stations impedes road vehicle electrification. The public charging station, a socially produced artefact, is subject to customer preferences and government regulatory limits. However, traditional knowledge does not completely capture the complex dynamics behind the public charging station investment, and a combined interactive decision review is inadequate. To examine enhanced dynamic interactions, this paper provides a complex network evolutionary game model. According to the findings, subsidies for charging infrastructure construction are more vital than electric vehicle subsidies. Under present market conditions, removing the electric vehicle subsidy reduces the market percentage of charging stations by 6%, whereas removing the charging station construction incentive results in a 35% decline. Second, charging price and charging station diffusion has an inverted U-shaped relationship, and increasing the oil price slows charging station dispersion. Third, the construction cost has less of an influence on charging station diffusion. Finally, green consumer preferences are the key driver of public charging station investment. An increase in consumer preference from 0.17 to 0.38 would lead to a 30% increase in the market share of the charging station industry from 53% to 83%. Based on these results, policy implications for the investment in public charging stations are discussed.

      Abstract: Energy & Environment, Ahead of Print.
      After spending several years as net importer of natural gas, the development of unconventional gas reserves in Argentina can revert this scenario and change the dynamics of the Southern Cone regional gas integration. To assess the role of Argentine gas, this study utilised the TIMES-ConoSur optimisation model, which represents the regional integration of the gas and electricity systems. To improve the level of detail of the results, updates and modifications in different settings were made in the first version of the model. In addition, four scenarios were tested with two levels of LNG (liquefied natural gas) prices and including or not the interconnection between Argentina gas network and Brazil integrated network. The role of the Argentine gas was analysed based on its production potential and the export potential to the neighbour countries. Findings indicated that the development of the Argentine gas reserves can be a game changer, as it can affect directly the regional dynamics and the gas supply of the neighbour countries. The main future dynamics of the other countries in the region were also assessed, such as the role of Bolivian gas, the challenges to develop pre-salt gas and how will be the future of LNG in the region.

      Abstract: Energy & Environment, Ahead of Print.
      This article considers the motivational nature of business contributions toward sustainable development through corporate social responsibility. This study measures the corporate social responsibility contributions to maintain sustainable development by performing different sustainable development goals projects. The researchers use the quantitative techniques to analyze the data collected by using the monkey survey research method from the top 200 corporate social responsibility international origin companies, including public sector undertaking, private and exchange-listed companies (Bombay Stock Exchange, and National Stock Exchange) in India. For analysis purposes, results are calculated through coding, sorting, figures, and tabulation methods. Study results illustrate that corporate social responsibility is the best source to maintain sustainable development as overall contributions towards sustainable development goals are positive. But a particular contribution towards sustainable energy as sustainable development goal 7 is low, such as only 5.5%. It is possible that India's green energy sector may be advanced if more companies invest in energy-related projects like the others sustainable development goals performance. Based on the results, possible steps are also needed from the Indian government to maintain sustainable development at the national and global levels.

      Authors: Haotian Zhang, Xiumei Sun, Mahmood Ahmad, Xueyang Wang
      Abstract: Energy & Environment, Ahead of Print.
      As an important market-based environmental policy, carbon emissions trading has played an increasingly important role in promoting energy conservation, emission reduction, and green innovation. The Chinese government started to implement a Carbon Emission Trade scheme in 2013 successively. This study uses a multi-period difference in difference to investigate the impact of Carbon Emission Trade on green innovation in panel data of listed companies from 2008 to 2020. The results show that: (1) Carbon Emission Trade significantly improves green innovation by 0.1916%. The robust test verifies the results. (2) The impact of Carbon Emission Trade on green innovation is heterogeneous at regional, industrial, and firm levels. From the regional level, Carbon Emission Trade has a stronger effect on regions with high marketization and low emissions. From the industry level, the policy effects are more pronounced in technology-intensive industries and the power industry, and negative policy effects are generated in Chemical industry, steel, and paper industries. From the enterprise level, Carbon Emission Trade shows better policy effects in state-owned enterprises, large enterprises. (3) Carbon Emission Trade enhances green innovation by reducing corporate financing constraints, improving corporate human capital, and strengthening government. (4) The enhancement of green innovation by Carbon Emission Trade balances the benefits. Increasing carbon price, market size and activity inhibit the increase of Carbon Emission Trade on green innovation. Based on the findings, the paper provides a new reference for the establishment of a carbon market.

      Authors: Pedro Chévez, Dante Barbero
      Abstract: Energy & Environment, Ahead of Print.
      Given the massive deployment of smart meters at international level, it is necessary to develop methodologies to extract knowledge from the data that they can provide. To this end, it is necessary to associate energy, socio-demographic and/or technical-constructive data, because this is the only way to identify profiles with their corresponding relevant variables or drivers. The usual problem is that socio-technical information about users is limited or non-existent, as it is costly to collect. Consequently, this work presents as a novelty the use of census information to characterize groups of urban segments with similar daily electricity load curves, which avoids the need to collect socio-technical information through specific surveys or direct measurements. In this way, relevant variables are identified in the determination of consumption patterns in the study case (Montevideo-Uruguay) and they are used to infer the daily behavior of those sectors of the city that don’t have this information.

      Abstract: Energy & Environment, Ahead of Print.
      India remained the third-largest energy consumer in the world, responsible for around 7% of global carbon emissions due to rising incomes and improving living standards. Although resource extraction has quadrupled since 1970 due to rising population and demand for natural resources, energy use and transformation, notably of fossil fuel energy, have increased by around 45%, thus increasing greenhouse gas (GHG) emissions. In this view, this study aims to explore energy intensity, renewable energy, natural resources, economic growth, and environmental degradation nexus in India. The novel dynamic simulated autoregressive distributed lag and kernel-based regularized least squares (KRLS) approaches are used to explore the effects of energy intensity, renewable energy, natural resources, and economic growth on carbon intensity for India from 1970 to 2020. The empirical results reveal that renewable energy and natural resources improve India's environmental quality via the mitigation of carbon emissions. It is also found that energy intensity and economic growth deteriorate the country's environmental quality by increasing carbon emissions in the short- and long run. A series of robustness estimation affirms the above evidence, thus providing requisite guideline for relevant policy recommendations for the country.

      Abstract: Energy & Environment, Ahead of Print.
      This paper examines the impact of informal economy and ecological footprint on environmental regulation for a sample of 25 Sub-Saharan Africa economies (SSA) countries from 1991 to 2017. The results obtained from the techniques of static panel (Pooled ordinary least squares (POLS), random effects (RE), fixed effects (FE), and panel corrected standard error (PCSE)) as well as from dynamic panel (generalized method of moments in differences (D-GMM), and generalized method of moments in system (S-GMM)) were all consistent. They showed that the environmental regulation has a significant positive impact for both informal economy and ecological footprint in the selected economies. Regarding the relation between ecological footprint and per capita gross domestic product (GDP), an inverted U-shaped environmental Kuznets curve is verified. The study concludes that weak environmental regulation in the region reinforces informal economy and environmental pollution. Hence, findings from this study can help policymakers in the region to have a better understanding of the role of environmental regulation in reducing informal economy and environmental degradation.

      Abstract: Energy & Environment, Ahead of Print.
      This paper aims to systematically explore the impact of renewable energy consumption, trade openness, industrialization, and urbanization on economic growth and carbon emissions while considering the different development levels of 122 countries over the period 1998–2018. Pesaran CD test, CIPS unit root test, Pedroni cointegration test, fully modified ordinary least square (FMOLS) estimation, Dumitreschu–Hurlin causality test and DOLS robustness test are adopted. The results show that trade openness has different effects on economic growth and carbon emissions across different income groups. Specifically, the impact of trade openness on economic growth in high- and low-income countries is positive, while trade openness has a negative impact on economic growth in middle-income countries. Meanwhile, the impact of trade openness on carbon emissions supports the pollution haven hypothesis. Urbanization promotes economic growth in all income countries, and increases carbon emissions in countries of all income groups except high-income countries. Renewable energy consumption promotes economic growth and curbs carbon emissions, while industrialization increases economic growth and carbon emissions. Further findings show a one-way causality from trade openness to renewable energy consumption. Finally, some targeted recommendations are provided for countries with different development stages.

      Abstract: Energy & Environment, Ahead of Print.
      The scarcity of energy resources and global warming over the past few decades have prompted the widespread adoption of renewable energy sources. Among the potential renewable energy sources, solar energy has emerged as one of the most promising renewable energy sources. However, the uncertainty and fluctuations of solar power generation create negative impacts on the stability and reliability of the electric grid, planning of operation, economic feasibility, and investment. Therefore, accurate prediction of solar power generation is crucial to ensure the stability of the power grid and promote a large-scale investment in a solar energy system. A large number of research studies have been conducted on predicting solar power generation under different perspectives. However, no existing study analyses and predicts power generation of multi-solar energy sites by only one prediction model. The integration of multiple sites into one predictive model will reduce the number of required models for each site, thereby saving the computing resources and required calculation time. This paper proposes a novel methodology to group multiple solar sites and develop an integrated model by using a machine learning algorithm to predict power generation of each group. Firstly, the K-means clustering algorithm is utilized to cluster multiple solar sites which have similar power generation properties into one group. Then, a machine learning algorithm has been developed to predict power generation in a computationally fast and reliable manner. The proposed approach is verified by the real data of 223 solar sites in Taiwan. The experimental results show that the training time can be reduced by 93.2% without reducing the accuracy of the prediction model. Therefore, the cluster-based prediction approach gives better performance as compared with existing models.

      Abstract: Energy & Environment, Ahead of Print.
      This article investigates dynamic networks of the informational efficiency between European Union carbon and energy markets in a quantile-based framework. The market (in)efficiency degree is gauged by capturing the potentially fractional integration order of the market price series using the Feasible Exact Local Whittle estimator on a rolling basis. Rather than relying on a mean-based method, we employ the causality-in-quantiles approach, through which the cross-market linkage of the inefficiency degree is uncovered in a full-distributional characterization. The dynamic linkage is identified through the perspectives of data in return and volatility, respectively. We find that both carbon and energy markets are inefficient, while the inefficiency degree of the former is slightly higher. The inefficiency degree of the two types of markets is featured by asymmetry and non-linearity over the data distribution, while its cross-market linkage is found to be bi-directional. The spillover degree of the dynamic linkage remains the highest at around the median quantile of the “information giver,” while such the degree weakens at the extreme quantiles. Our findings possess insightful implications for effective operations of the emission trading toward a low carbon transition.

      Abstract: Energy & Environment, Ahead of Print.
      The primacy of logistics, environmental sustainability, and institutions for sustainable development has attracted the attention of researchers and policymakers. However, the role of institutions in the logistics–environment relationship has not been documented in the extant literature. Thus, this study examined the role of institutional (governance) quality on the logistics–environment nexus and compared the case of developed and developing economies using a state-of-the-art econometrics technique—Chudik-Pesaran (2022) Augmented Anderson–Hsiao two-step Generalized Method of Moment estimator for dynamic short-T panels, which is superior to previously used techniques in the extant literature. Key empirical findings outline a positive elasticity of environmental performance with respect to logistic performance and revealed that institutional factors play a significant role in the association between logistics performance and environmental sustainability in both developed and developing economies. The study results are useful for practitioners and key players and policymakers in the supply chain and logistics management industry in both developing and developed blocs. Thus, policies on green logistics and environmental sustainability should be pursued in both blocs are suggested in the concluding section of this study.

      Authors: Mukund Kumar, Abhishek Paul
      Abstract: Energy & Environment, Ahead of Print.
      The present work focuses on the impact of combustion phase shifting from CDC (conventional diesel combustion) to RCCI (reactivity controlled compression ignition) mode of operation under various premixed ratios of hydrogen on the combustion, performance and exhaust emissions of a partially modified CI (compression ignition) engine. The hydrogen premix ratios are varied from 10% to 60% with 10% increment and the engine is tested at 0.9 kW, 1.8 kW, and 2.7 kW. The experimental results have shown that the hydrogen participation up to 40% premixed ratio improves the homogeneousness and stability of the combustion, resulting in 8.19% increase in cylinder pressure and 27.81% increase in heat release rate (HRR) at 2.7 kW brake power. It is also observed that the premix phase of combustion is faster with up to 40% hydrogen participation as the 50% mass burn is found to shift towards TDC. At the same operating point, the combustion is also found to be more stable with 72% reduction in COVIMEP. The brake thermal efficiency (BTE) increases by 10.07% when operating at 2.7 kW brake power with a 40% premix ratio, compared to diesel CDC operation. The unburned hydrocarbon (UHC), carbon monoxide (CO), and PM emissions are reduced by 9.17%, 21.68%, and 9.51%, respectively, for the hydrogen premixed ratio of 40%, with a marginal increase in the oxide of nitrogen (NOX) emissions.

      Abstract: Energy & Environment, Ahead of Print.
      In this paper, we researched the implication of international migration and pollution on environmental development of the selected countries which we classified as middle- and upper-income countries. Maintaining good environmental performance while keeping pollution at minimum level amidst international migration has being the global focus towards climate goal. On this premises, this study examines the relationship between international migration and carbon dioxide emission (CO2). Scientific approaches (random-effects model and Driscoll-Kraay standard error estimator) with panel data for the period from 2010 to 2019 are adopted for indepth analysis of the selected countries. The findings according to random-effects model/Driscoll-Kraay standard error estimator suggest the incresae of CO2 due to increase in international migration for the case of middle-income countries. Also, a decrease in CO2 due to increase in international migration is found for high-income countries. Following our main findings, as a function of CO2 emission, we recommend to take identity of people who migrate into consideration for both economics and environment policy. On the other hand, policies should be based on mitigating the negative impact of international migration and economic growth for the middle-income countries. Moreover, environmentally friendly growth technologies are suggested.

      Abstract: Energy & Environment, Ahead of Print.
      The interest in the trade–environment nexus is growing for emerging countries as their participation in world trade is increasing. However, the available evidence regarding the non-renewable energy effects of trade in intermediate and final products is limited. This study addresses this gap and investigates the separate effects of per capita exports and imports of intermediate and final products on per capita non-renewable energy supply (NES) in the case of 22 emerging industrial economies (EIEs) between 1995 and 2018. The study also considers per capita environmental inventions (EnvINV), industry value-added (IND), services value-added (SERV), and renewable energy supply (RES). After confirming that the modeled variables are cross-sectionally dependent, first-difference stationary, and cointegrated, the long-run heterogeneous coefficients are estimated through the common correlated effects mean group and augmented mean group estimators. Consistent results show that although both are positively associated with NES, the magnitudes of the impacts of intermediate product imports are higher than that of intermediate product exports. Similar effects are observed in the final product trade. The Dumitrescu–Hurlin test finds unidirectional causalities from all trade indicators to NES. Additional results reveal positive impacts of IND and SERV, negative effects of RES, and insignificant impacts of EnvINV. Several policy insights are provided to better inform practitioners about the environmental implications of emerging economies’ trade specialization pattern in energy-intensive global production networks.

      Authors: Yiqun Yang, Kevin Lo
      Abstract: Energy & Environment, Ahead of Print.
      The ambitious targets of peaking CO2 emissions before 2030 and reaching carbon neutrality before 2060 (Goal 3060) have emerged as the driving force in the development of China's low-carbon energy policy. Adopting a systematic review approach, this article provides a timely analysis of key Chinese renewable energy and energy efficiency policies under Goal 3060 across five sectors: electricity, industry, transportation, buildings, and local governments. In addition, the review identifies challenges to be addressed and offers policy recommendations. There are five main conclusions: (1) expedite the development of market-based and network-based governance systems; (2) pursue the harmonization of policies by avoiding contradiction and fragmentation; (3) develop new policies, especially in the building and transportation sectors; (4) embrace surveillance technologies to improve implementation and compliance; and (5) ensure just transition by implementing policy to reduce the negative socioeconomic impacts on fossil fuels-based communities and workers. This review serves as a useful guide for scholars interested in China's clean and low-carbon energy transition.

  • How can corporate social responsibility predict voluntary
           pro-environmental behaviors'

    • Free pre-print version: Loading...

      Authors: Stanley YB Huang
      Abstract: Energy & Environment, Ahead of Print.
      This article proposes the multilevel model to draw how corporate social responsibility (CSR) can increase pro-environmental behaviors and employs green identity as the mediator based on cognitive consistency theory. This article employs the multilevel model to test the theoretical framework using 400 employees from 100 different workgroups in the clean energy technology businesses of Greater China. The findings revealed that when an employee perceived more individual-level CSR at the initial time (Time 1) would increase more individual-level green self-categorization (GSC), green affective commitment (GAC), and green self-esteem (GSE), which consequently increased pro-environmental behaviors (PBs) at the individual level and work-unit level. This finding suggests that managers not only must build individual-level perceived CSR of employees but must also foster work-unit-level (atmosphere) CSR within a group to increase work-unit-level GI, which consequently can increase PBs.

      Authors: Xiaowei Song, Jun Yang
      Abstract: Energy & Environment, Ahead of Print.
      In the context of carbon emission reduction, both servitization and digitalization of manufacturing enterprises are important ways to promote the high-quality development of manufacturing enterprises. The coordinated development of digitalization and servitization may provide a feasible path for enterprises to realize energy conservation and emission reduction across the value chain. Based on the 393 valid questionnaires issued by the Association of Manufacturing Enterprises and government agencies, this paper uses the methods of Grey Relational Analysis and Topsis to construct three major indicator systems of manufacturing enterprise service, digitalization and high-quality economic development. Based on the Cobb–Douglas production function regression analysis, the relevant assumptions involved in the model of promoting the service of manufacturing enterprises and the model of promoting the digitalization of manufacturing enterprises are verified. The empirical results show that, firstly, the digitalization capability of manufacturing enterprises can positively affect the servitization performance of manufacturing enterprises. Secondly, the digital capability of manufacturing enterprises has a significant positive impact on both breakthrough service innovation and incremental innovation of manufacturing enterprises. Thirdly, breakthrough service innovation and incremental service innovation play a partial mediating role. Fourthly, the degree of servitization of manufacturing enterprises has a significant positive impact on the digital demand of supporting customer behavior service business and supporting customer product service. There are three possible contributions of this paper. Firstly, it has further enriched and deepened the research on the interactive mechanism of digitalization and service of manufacturing enterprises. The second is to design a scientific and systematic evaluation system for the digitalization and service level of Chinese manufacturing enterprises, and measure and evaluate the coupling and coordination level of digitalization and service level of Chinese manufacturing enterprises based on this. Thirdly, it reveals the promotion of the coordinated development of digitalization and service in manufacturing enterprises to the high-quality development of manufacturing enterprises in China and puts forward that the coordinated development of digitalization and service in manufacturing enterprises is a way to promote the high-quality development of manufacturing enterprises.

      Abstract: Energy & Environment, Ahead of Print.
      This research investigates the relationship between clean energy stock and oil market returns utilizing Granger predictability in distribution and quantile impulse response analysis. We find that clean energy stock returns Granger predict oil price returns during “normal times” based on the distribution’s center, but not vice versa. During bullish market episodes, there is bidirectional Granger predictability between the returns of clean energy stocks and oil market returns. Nonetheless, we find that clean energy stock returns Granger predict oil returns in bearish markets without any evidence of the contrary. This indicates that oil returns cannot be used to hedge the downside risk associated with renewable energy company purchases. Quantile impulse responses for the relationship between clean energy stocks and the crude oil market reveal bidirectional and significant responses, where a negative shock during an extremely down market reveals a negative response in the other market and a positive shock during an extremely up market reveals a significant positive response. This shows that neither market can be utilized to offset risks in the other market.

      Authors: Inseok Seo, Youhyun Lee
      Abstract: Energy & Environment, Ahead of Print.
      Since the concept of energy justice emerged, studies have conceptually, but rarely empirically, explored energy justice. In addition, studies on energy justice have mainly focused on anthropocentric values toward energy justice. This study aims to categorize Organization for Economic Cooperation and Development (OECD) countries’ energy justice using synthetic energy justice via two aspects: eco-centrism and anthropocentrism. Each aspect of energy justice is sub-divided into distributive, substantive, and procedural justices. Using a fuzzy set qualitative comparative analysis methodology via a statistical program, we suggest typologies of 35 OECD countries for each aspect. Eight types of energy justice for each aspect are extracted, and four types of synthetic energy justice groups are identified among OECD countries. Austria, Iceland, and Luxembourg show the best performance in synthetic energy justice, but do not reach a complete contestable status from an eco-centric perspective. This study provides practical policy implications for OECD countries to self-evaluate each country's macroscopic policy direction in the energy sector, and to ultimately pursue synthetic energy justice with a balanced perspective for our environment and us.

      Abstract: Energy & Environment, Ahead of Print.
      This study explores the effect of green bonds, oil prices, and the coronavirus disease 2019 (COVID-19) pandemic on industrial carbon dioxide (CO2) emissions. In this context, this study examines the United States of America (USA), which is the biggest economy in the world, uses weekly data between March 6, 2020 and September 30, 2022, and applies a novel wavelet local multiple correlation (WLMC) approach under time-varying and frequency-varying perspective. The novel empirical findings shows that (i) there is a strong negative (positive) co-movement between industrial CO2 emissions and green bonds in the short-run (long-run); (ii) there is a strong positive (negative) co-movement between industrial CO2 emissions and oil price in the medium-run (long-run); (iii) there is a strong negative (positive) co-movement between industrial CO2 emissions and the COVID-19 pandemic in the medium-run (long-run); (iv) the oil price is the dominant factor, whereas there are changing effect of the variables on each other at different times and frequencies; and (vi) overall, there are long-run asymmetric and dynamic correlations between industrial CO2 emissions and variables. Hence, the empirical results highlight the asymmetric, time-varying, and frequency-varying effects of green bonds, oil prices, and the COVID-19 pandemic on industrial CO2 emissions by presenting fresh and novel evidence. Moreover, the study proposes policy implications for the USA government.

      Abstract: Energy & Environment, Ahead of Print.
      Although the Chinese government has effectively enacted green policies to address climate challenges, the country's heavy reliance on fossil fuels has made these problems serious barriers to China's sustainable growth. This study analyzes data from 653 Chinese manufacturing companies and examines the relationship between corporate social responsibility and environmental performance. The suggested hypotheses have been investigated by employing structural equation modeling. The results showed that there is no direct association between corporate social responsibility and the environmental performance of manufacturing firms. In comparison, it is linked to green transformational leadership and green innovation that improves environmental performance. Furthermore, the results showed that the link between corporate social responsibility and environmental performance is mediated by green innovation and green transformational leadership. The study's results provide managers and decision-makers in manufacturing businesses with critical knowledge on managing corporate social responsibility, green innovation, and green transformational leadership. Increasing internal resources to improve environmental performance may be advantageous to general managers of big manufacturing enterprises.

      Authors: Festus Victor Bekun, Bright Akwasi Gyamfi, Cihat Köksal, Amjad Taha
      Abstract: Energy & Environment, Ahead of Print.
      The present study is motivated by the need to decouple economic growth from environmental degradation given the new wave of chase for higher economic growth trajectories comes with its environmental cost implications, especially among developing blocs like the Emerging 7 (E7) countries. There is a consistent trade-off between economic growth versus environmental quality. Government apparatus are perpetually on the chase for low-carbon emission policies via the pursuit for green economy. To this end, this present study extends the conventional environmental Kuznets curve (EKC) argument by incorporating the role of institution in emerging industrialized economies (E7) and using second-generation panel analysis methods like mean group (MG), augmented mean group (AMG), common correlated effects mean group (CCEMG), and the Dumitrescu and Hurlin causality test for more robust estimates and inferences. To this end, we explore the long-run and causality relationship between economic growth, quadratic form of economic growth, institutional quality, trade flow, investment in energy sector, and financial development in an EKC environment. Empirical analysis established a long-run equilibrium relationship among the outlined variables over the study period. The long-run regression shows the presence of EKC in the E7. Thus, suggesting the preference for GDP growth over environmental quality at the earlier stage of growth curve. Interestingly, investment in energy, trade flow dynamics across the blocs, and financial development dampens the detrimental effect of environmental pollution as we observed negative relationship with the ecological footprint. On the contrary, quality of institution is weak as institutional quality increase (worsen) the quality of environment in the E7 economies. From a policy perspective, this current study proposed the need for more stringent environmental treaties and regulations and promotion of green economy without compromising economic growth. In the conclusion part of the study, more details and specifics about the policy blueprint are presented.

      Authors: Sana Ghorbal, Slim Ben Youssef
      Abstract: Energy & Environment, Ahead of Print.
      South Korea is considered one of the leading countries in innovation and research and development (R&D), in particular in renewable energy R&D efforts, but it is also one of the more polluting countries. So, understanding the interplay between these variables is of great interest. The main objective of this article is to examine the relationship between carbon dioxide (CO2) emissions, economic growth (GDP), renewable energy consumption (RE), foreign direct investment (FDI), home patents (HP), and foreign patents (FP) in South Korea using data ranging from 1980 to 2018. For this purpose, the autoregressive distributed lag (ARDL) approach and Granger causality tests were employed. Estimates of long-run elasticity point to a positive relationship between GDP and CO2 emissions. FP and RE have a negative influence on CO2 emissions but they have a favorable effect on GDP. FDI and HP have positive impacts on CO2 emissions. Granger causality outcomes demonstrate that CO2 emissions, GDP, RE, and FP have long-term bidirectional causal relationships. In the short-run, there are unidirectional causalities running from FP and FDI to RE and from FDI and HP to GDP. Besides, there is a bidirectional causality between GDP and RE. South Korea should continue to promote renewable energies and facilitate the use of foreign patents, particularly those relating to renewable energies. This will lead to a reduction in its carbon emissions while benefiting its economic growth.

           environmental regulation

      Authors: Ronghui Xie, Shengjie Zhang
      Abstract: Energy & Environment, Ahead of Print.
      One important and frequently raised issue about foreign direct investment (FDI) is its potentially environmental consequences. In recent years, as severe haze pollution has broken out worldwide, whether FDI inflows increase PM2.5 spillages in a country has sparked a new round of heated discussion. This study attempts to empirically investigate how FDI affects haze pollution in various countries, by employing a cross-country panel dataset during the period 2010–2017, and further to examine the interactive effect of environmental regulation and FDI in the FDI–pollution nexus. Based on a two-way fixed-effects model with robust standard errors, the estimation results show that FDI inflows significantly lead to an increase in PM2.5 exposure, therefore, confirming the validity of the Pollution Haven Hypothesis. Moreover, environmental regulation generally appears to be ineffective in directly reducing haze pollution but acts as an essential underlying mechanism in the relationship between FDI and haze pollution. Under the moderation of environmental regulation, the positive marginal effect of FDI on PM2.5 continues to decrease until it becomes negative. The findings suggest that countries, especially developing countries and emerging economies should consider a mix of policies to manage its inward FDI to achieve sustainable development in the post-financial crisis era.

      Authors: Zhiming Yang, Xijie Zhuang, Jiuling Li, Guanghui Zhang, Yunquan Zhang, Lifu Fu, Chengyou Li
      Abstract: Energy & Environment, Ahead of Print.
      The health risks of cooking with solid fuels are widespread, especially among low-income people. Therefore, we decide to explore the impact of cooking fuel on the physical and mental health of Chinese residents and the heterogeneity of effects across income groups. This study estimates the potential relationship between household air pollution and health status by using data from the China Family Panel Studies (CFPS). Household air pollution is measured by different types of cooking fuels, and health status is evaluated from the perspective of respondents’ self-ratings of health, mental health, and interviewer-assessed health. The data comprises more than 100,000 samples between 2012 and 2019. We employ a Hierarchical Linear Model to infer the potential impact of household air pollution caused by cooking fuel on residents’ health. After adjusting control variables, we find cleaner cooking fuels such as solar energy and biogas are more conducive to residents’ health status. Our findings manifest that cleaner fuels and lower exposure to household air pollution are better for residents’ health. Low-income households are more likely to be affected by household air pollution. This study emphasizes the consequence of the potential health effects on residents due to household air pollution from cooking fuels and the uneven distribution of those effects. It is recommended that such factors as household air pollution risks, health, and environmental fairness and justice should be considered in the policy formulation process.

      Authors: Solji Nam, Jungwoo Shin, Bum Il Hong
      Abstract: Energy & Environment, Ahead of Print.
      Global warming concerns have emphasized the need for carbon neutrality. Improving the efficiency of the electricity industry is one method of reducing CO2 emissions. There is a demand response policy that trades the saved electricity through voluntary adjustment of consumption patterns. The introduction of real-time pricing (RTP) based on advanced power supply systems is a method of transitioning to a demand-oriented power system. However, as Korea's power supply system is a relatively less efficient single-rate system, it is necessary to improve the efficiency of demand management. To transition to a demand-oriented power system in Korea, consumer preference is first investigated. This study evaluates the willingness to pay (WTP) for the introduction of RTP in Korea. Based on a survey of 500 households using the contingent valuation method, the monthly average WTP was found to be 2465 Korean won per household ($2.18 per household), which is approximately 7.8% of the electricity rate. Several additional factors influencing WTP were analyzed. Further analysis indicated that it is more effective to establish infrastructure for introducing RTP in local areas with low average electricity rates. These findings are beneficial for the development of future demand response policies.

      Authors: Hanhua Shao, Xinpeng Huang, Huwei Wen
      Abstract: Energy & Environment, Ahead of Print.
      In developing countries, foreign direct investment (FDI) plays a significant role in industrial catch-up concerning knowledge acquisition and technological innovation. The Chinese government's development strategy is vital in attracting FDI and green innovation (GI). This article investigates the moderating role of development strategy in the causal relationship between FDI and GI from the perspective of new structural economics. We find a U-shaped association between FDI and GI. Specifically, FDI inhibits GI at its low level, and FDI promotes GI with the accumulation of FDI capital. Therefore, cities with moderate catch-up strategies can maximize the impact of FDI on GI. Development strategies can also hinder the effects of FDI-driven GI in cities with a perfect market system while promoting them in cities with relatively backward, cleaner production technology. The development strategy not only has an impact on the FDI-driven GI effects in the region but also on the FDI-driven GI effects in the surrounding regions through the spatial spillover effect. These findings provide references on what type of FDI the government should introduce and how to guide the market to bring the GI effect of FDI into play.

      Abstract: Energy & Environment, Ahead of Print.
      This is a sustainable study of China amidst high carbon emissions. China has experienced tremendous increase in its economic operations and development which involve the excessive utilization of fossil fuel energy sources. This has put China in the list of nations that contribute towards global warming via carbon emission. On this note, data from China over the period 2002Q1–2019Q4 is analyzed, using multiple techniques (nonlinear autoregressive distributed lag-NARDL, fully modified ordinary least square-FMOLS, and bootstrap approach of Granger causality) for clear insight into China's sustainable development. Relevant instruments (technological innovation, entrepreneurial activities, economic growth proxied by GDP, fossil fuel energy consumption, and FDI) are used to measure China's economic and environmental performance to determine the level of sustainable development of the country. NARDL and FMOLS results reveal that technological innovation and entrepreneurial activity mitigate carbon emissions, while fossil fuels and economic growth induce China's carbon emissions. Also, findings from the bootstrap approach affirm the NARDL and FMOLS outcomes, with both two-way and one-way nexus established among the selected variables. Policies targeting the reduction of fossil fuel consumption in China despite the technological innovations and entrepreneurial activities are thus recommended.

      Abstract: Energy & Environment, Ahead of Print.
      A complete understanding of the interplay between environmental regulations and fiscal decentralization for the realization of health outcomes is crucial for policy formulation and decision-making. The aim of the study is to investigate both policy variables’ separate and combined impacts using data on four BRICS economies from 2000 to 2020. The study has employed the novel method of moments quantile regression to quantify the effect. The findings of the study show (i) a significant impact of regulations on health outcomes in higher quantiles. Environmental regulations have a strong positive impact on all three-health proxies, that is, health expenditures, life expectancy, and the number of infant deaths. Total revenue and expenditure decentralization affect health outcomes positively, while tax revenue decentralization negatively impacts them, with the effect being stronger in the lower quantiles; (ii) the combined impact of decentralization and environmental regulations turned out to be negative and significant in our study; and (iii) all variables have unidirectional causality. However, with tax revenue decentralization, health expenditures, life expectancy, and infant deaths have bidirectional causality. This finding has a strong policy implication for the policymakers. Although both policies positively impact health indicators, their interaction leads to deteriorating health outcomes. From a policy point of view, it is suggested to strike a balance between regulations and fiscal decentralization to realize the full potential of this policy mix to get better health outcomes. This study adds to previous research by incorporating the interconnected impact of environmental regulations and fiscal decentralization on health outcomes in BRICS economies.

      Abstract: Energy & Environment, Ahead of Print.
      The energy-saving effect of financial development is directly related to the formulation and implementation of financial policies. Considering the inertial characteristics of energy consumption, this study tested the energy-saving effect of financial development and examined its heterogeneity in terms of low-carbon cleaning and policy change. The results were as follows: First, when energy consumption was at the lower quantile, as consumption increased, the promoting impact of financial development on energy consumption decreased. When energy consumption was at the upper quantile, as consumption increased, the restraining impact of financial development on energy consumption increased. Second, an increase in the quantile level showed that financial development exerted an increasingly stronger influence on promoting clean energy consumption. When non-clean energy consumption was at the upper quantile, financial development exerted an increasingly strong inhibitory effect on non-clean energy consumption. Third, before green credit policy changed, the energy-saving effect of financial development was not widespread and obvious. After green credit policy changed, the restraining impact of financial development on energy consumption increased with the level of consumption. Fourth, after green credit policy changed, compared with the increase of financial development toward promoting clean energy consumption, the inhibitory effect of financial development on non-clean energy consumption significantly improved relative to the second case.

      Abstract: Energy & Environment, Ahead of Print.
      Due to the adoption of more financial inclusion (FI), energy utilization with sustainability became a challenge for world economies. Our research examines whether FI symmetrically and asymmetrically affects environmental sustainability in Pakistan. Six proxies are indexed for the FI data through principal component analysis (PCA). In the present research explanatory variables are, energy usage, industrialization, urbanization, and human capital during from 1975 to 2018. Our study engaged the Stochastic Impact by Regression on Population, Affluence, and Technology Approach (STIRPAT). Additionally, the econometric strategy is adopted for the empirical analysis to acquire the symmetric and asymmetric outcomes. The empirical result validates the asymmetric association of FI and carbon dioxide (CO2) emanations in short and long lags. Besides, fossil energy utilization, industrialization, and urbanization smoothen the path of environmental pollution. However, human capital significantly aids in reducing carbon pollution in the short and long terms. The policy makers can practically implement the research to utilize FI effectively to improve environmental sustainability and develop policies that discourage fossil energy utilization. Moreover, we pointed out the alarming situation of dealing with harmful emissions from urbanization and industrialization.

      Abstract: Energy & Environment, Ahead of Print.
      This study emphasizes the comparative investigation of the thermal capacity of parabolic solar trough collectors with spherical-shaped balls and two types of elliptical inserts (longitudinal orientation). Hybrid nanofluid is the heat-carrying liquid obtained by mixing CuO and Al2O3 nanoparticles in distilled water. Analytical investigations are conducted for 1% vol. concentration of hybrid nanoparticles in distilled water for varying proportions. Computational analysis is chosen to obtain thermal as well as flow trends in the tube receiver. The outcomes disclosed that 13.3%, 10.02%, and 16% improvements are noted for thermal efficiency, Nusselt number, and thermal performance index with elliptical inserts of minor diameter 12 mm in the receiver, respectively, than spherical ball inserts. The highest pump work of 35 W is associated with spherical inserts at 0.033 kg/s.

  • A new city's water–energy nexus implications: The case of Sejong
           City in South Korea

      Authors: Jae-Ho Yoo, Hana Kim
      Abstract: Energy & Environment, Ahead of Print.
      Cities’ impact on water, energy, and greenhouse gas (GHG) emissions is increasing as the world becomes more urbanized. Focusing on Sejong City, which was developed as a new administrative hub in South Korea in 2012, this study scrutinizes its development path from water–energy nexus perspective by developing a system dynamics model that describes the interactions among numerous components related to water and water-related energy consumptions. Furthermore, this study reimagines the city's potential development trajectories by constructing nine policy scenarios that combine different degrees of water conservation ambitions with different amounts of decarbonization in the power sector. The results confirmed the potential of water conservation policies. The expansion of rainwater use has the potential to cut water use by 50% from the 2050 baseline levels. Although the use of harvested rainwater is negligible compared to wastewater reuse, its overall effect on water conservation would be substantial if it is increased. The maximum reduction in GHG emissions from the water sector would be 9.36% from the 2050 baseline scenario when combined with decarbonizing the power sector. Although this study does not fully account for the water conservation potential, including the efforts at the end-use stages, the possibility of carbon neutrality in Sejong's water sector by 2050 is presented. It affirms that local governments can significantly reduce cities’ environmental footprints and complement national efforts for the transition to a carbon-neutral society.

      Authors: Xiaoyi Li
      Abstract: Energy & Environment, Ahead of Print.
      This paper analyzes the economic, social and political three-dimensional driving effects of new energy substitution for fossil energy under the joint action of market, government and international competition from three perspectives: profit motive, mutual benefit and responsibility motive, combined with the relevant data of 78 countries from 1965 to 2021. The results show that fossil energy prices and energy security positively influence the process of new energy substitution, and environmental pollution negatively affects the process of new energy substitution, and the pushback effect of energy security on new energy substitution is more significant in the study interval, indicating that at the beginning of the new energy revolution, global environmental governance and willingness to reduce emissions drive the development of new energy industry, but the “carbon emission reduction” of each country has increased the complexity of new energy substitution, especially in some developed countries in taking responsibility for global environmental governance divergent views. Further heterogeneity analysis reveals that each country’s energy strategy affects the degree of substitution of “quality” and “quantity” of new energy, and the speed, areas and corrective ability of new energy development vary among countries under different strategic choices.

      Authors: G Uma Maheswari, N Shankar Ganesh, Tangellapalli Srinivas, Bale Viswanadha Reddy
      Abstract: Energy & Environment, Ahead of Print.
      This article aims to examine a novel combined power and refrigeration system, using renewable and waste heat sources suitable for low-temperature applications. The present system is an integrated Kalina cycle and ejector refrigeration system to generate power and refrigeration simultaneously. To improve the vapour generation, the separator vapour fraction is used as a decision variable. Relative irreversibility and efficiency defect as two important parameters considered in this system for an investigation to identify the weaker components. The combined system generates power and refrigeration with two different mediums by the incorporation of the heat exchanger at the turbine exhaust. The novel system's energy and conventional exergy evaluation are carried out through Python Software. The optimum values of decision variables: turbine concentration, separator vapour fraction, entrainment ratio, expander ratio, split ratio and turbine concentration are identified using Python software from an opted range of variables. The maximum value of net power output, first law efficiency for power generation system, combined system, second law efficiency for power generation system, combined system, refrigeration effect and coefficient of performance are obtained as 113 kW, 8.85%, 11.83%, 93.44%, 81.29%, 38.07% and 0.118, respectively, at higher separator vapour fraction. Among the components considered in the combined power generation system, the condenser and LTRGN account for the higher exergy destruction rate of 30.41% and 25.53%. The coefficient of performance is maximized at a higher value of the refrigeration effect. The turbine pressure at the inlet is increased with increments in turbine work on choosing the higher value of the expander ratio. The higher exergetic value components are not emphasized to focus on improvement.

      Abstract: Energy & Environment, Ahead of Print.
      This paper examines the role of financial globalization and natural resource rents on carbon emissions in the case of Nigeria from 1970 to 2020 using Breitung-Candelin Spectral Granger-causality and wavelet coherence analysis. The spectral analysis decomposes variability in a time series into its periodic components, which is preferable for series that are short-spanned, nonlinear, or are characterized by seasonal and economic episodes, while the wavelet coherence analysis could produce localized decompositions both in time and frequency domains. Using these techniques, we find a one-way causal effect running from financial globalization and natural resource rents to carbon emissions within the specified scale and time. Financial globalization and natural resource rents are useful for predicting environmental degradation in Nigeria. Thus, policymakers should factor in financial globalization and natural resource rent when formulating environmental policies to mitigate climate change effect for the immediate and future generations. Financial penetration should be channeled toward green investment. The deposit money banks should provide and prioritize credit only to firms and individuals that consider investing in modern and clean technologies, while the policy on exploration and exploitation of natural resources should review to attract foreign investors that would improve the existing technologies or bring in energy-efficient and energy-saving ones.

      Abstract: Energy & Environment, Ahead of Print.
      Computer simulation of energy resources has led to significant achievements in the interdisciplinary fields of energy and environment. Apart from renewable resources, fossil-fuel power generation plants can be made cleaner to satisfy the future climate targets while keeping secure and stable grid. Clean coal power plants are still among the dominant options for power generation, which are committed through energy-efficient operation, carbon capture and storage, or combination of both strategies. On the other hand, machine learning and deep learning techniques have a leading integrity in the field of simulation. This paper presents accurate models of a cleaner coal-fired supercritical (SC) unit using two types of artificial neural network, which are Elman neural network (ENN) and generalized regression neural network (GRNN). The models newly embed higher coverage range and more accurate results than previously published models. Each subsystem of the models has been structured as a multi-input single-output (MISO) component to predict the behavior of significant variables in the plant, mainly the supercritical pressure in MPa, the steam temperature in °C and the production in MW. Those variables have been intentionally selected as they are clear indicators for the energy-efficient and cleaner production. Simulation results of four sets of data have indicated satisfactory performance of both models with a bit higher superiority of the GRNN that has given negligible or zero Mean Squared Error (MSE) for all outputs, whereas the minimum MSE of the deep ENN is 3.131  ×  10−3.

      Abstract: Energy & Environment, Ahead of Print.
      Biopolymer composite electrolytes consisting of cellulose acetate and magnesium perchlorate with different weight percent (wt.%) of Zinc Oxide fillers were prepared using the standard solution cast technique. The effect of incorporating various amounts of ZnO fillers in our composite electrolytes was investigated for their electrical and structural properties, and ion transference numbers. The ionic conductivity of 40 wt.% ZnO filler was found to be 8.75× 10−4 S/cm at 30 °C along with a 4.2 V electrochemical stability window. The ion transference number has been found to be 0.97 for CA + 40 wt.% of Mg(ClO4)2 + 40 wt.% with ZnO fillers. Furthermore, the electrochemical performances of the prepared electrolytes have also been investigated. The fabricated cell with this electrolyte shows an enhanced energy and high-power density of 2.78 Wh/Kg and 1000 W/Kg, respectively. An increase in the above-mentioned densities may be attributed to the high ionic conductivity ZnO fillers in the biopolymer matrix. Additionally, it shows 100% capacitance retention along with high coulombic efficiency after the 129th cycle.

      Authors: Muhammad Tayyab Sohail, Sana Ullah, Muhammad Tariq Majeed
      Abstract: Energy & Environment, Ahead of Print.
      The BCIST economies have reinforced their identity as an emerging power in the fields of environmental technology and green transportation. The green transport sector undoubtedly plays an important role in green growth but also reduces CO2 emissions. The present study's objective is to examine the impact of transportation taxes on CO2 emissions in a comparative setting for BCIST economies in periods ranging from 1991 to 2019 by employing the nonlinear ARDL approach. The finding shows that transportation taxes are also a vital asymmetric determinant of CO2 emissions. An upsurge in transportation taxes lowers CO2 emissions in China, India, South Africa, and Turkey, while a decrease in transportation taxes intensifies carbon emissions in Brazil, China, and India in the long term. More transportation taxes limit CO2 emissions in South Africa as well as China in the short run. The findings of the study have some important economy-wise policy implications and permit a new direction for further research.

      Authors: Tran Thi Mai Hoa, Le Thanh Ha, Nguyen Thi Thanh Huyen, Nguyen Thi Thu Ha, Tran Anh Ngoc
      Abstract: Energy & Environment, Ahead of Print.
      Our article is the first attempt to investigate the association between global value chains (GVC) and environmental performance (EP). We employ two dimensions, including human health's and ecosystem's protection, to capture the EP, while GVC is classified backward and forward based on the foreign and domestic value-added to the total exports. By applying the formal empirical estimation procedure to a global sample of 30 low-income and lower-middle-income and 27 upper-middle-income and 33 high-income countries during the 2000 to 2018 period, some key findings are highlighted. Our estimates emphasize the importance of GVCs on EP through their influences on environmental health and ecosystem vitality. By distinguishing between the effects of different types of GVC, we reveal that being engaged in forward GVC plays a more critical role in improving the environment than backward GVC. By studying the short-run and long-run effects, our study suggests that the GVC involvement has adverse effects in the short term, but positive results appear in the long term. Notably, the investigation into the mechanism of the GVC-EP nexus provides empirical evidence to explain how being included in GVCs affects the environment and sustainability of a country. Finally, our study indicates that there are heterogenous effects of GVC on EP and these effects are conditional on a country's income level. It is more likely that the impacts of GVC become more pronounced for high-income countries.

      Abstract: Energy & Environment, Ahead of Print.
      CO2 methanation is an effective strategy for making full use of waste gases and converting them into valuable chemicals. Nowadays, the key challenge is the design of efficient catalysts to enhance low-temperature catalytic performance. The present work studies the effect of metal type on the catalytic performance of yttrium oxide-supported catalysts for CO2 methanation reaction. Ru/Y2O3, Ni/Y2O3, and Co/Y2O3 catalysts were prepared by wetness incipient impregnation method, characterized using N2-adsorption/desorption isotherm, XRD, FTIR, and H2-TPR and TGA techniques to evaluate the surface, crystal phase, and thermal stability. The catalytic test was conducted with the use of a fixed-bed reactor under atmospheric pressure. The temperature of catalytic performance was 350 °C with a supply of H2: CO2 molar ratio of 4 and a total flow rate of 200 mL/min. The main products of the reaction were CH4, and traces of carbon monoxide were present among the products. The methane yield reached 64.67%, 60.03%, and 50.82% over Ru/Y2O3, Ni/Y2O3, and Co/Y2O3 catalysts, respectively.

      Metal ferrites like nickel ferrite, copper ferrite, zinc ferrite, cobalt ferrite, and other ferrites are highly abundant and used as catalysts in various transformations. However, CaFe2O4 is the most abundant alkali metal ferrite, which is eco-friendly and non-toxic. CaFe2O4 is a superparamagnetic material that can be easily recovered from the reaction media due to its magnetic properties. Therefore, it has been widely used in numerous applications, such as dye degradation, removal of heavy metal ions, transesterification reaction, gas sensing, photocatalytic water splitting, drug delivery, etc. In this review, (1) magnetic properties and crystal structure of spinal CaFe2O4 are discussed, (2) potential applications of CaFe2O4 are discussed, and (3) various synthesis techniques of CaFe2O4 are demonstrated. CaFe2O4 shows photocatalytic properties due to its narrow band gap (1.9 eV), abundant functional group, and high surface area. It is found that CaFe2O4 possesses a remarkable potential for energy and environmental remediation. In this review, we have added the photocatalytic mechanism of various pollutants. At last, future perspectives are given for developing novel, sustainable CaFe2O4 or CaFe2O4-based nanocomposite.

      This article proposes a hybrid technique for a grid-connected solar–wind hybrid system with electric vehicles. The Mexican Axolotl Optimization and wild horse optimizer are the proposed optimization techniques. The wild horse optimizer improves the axolotl's life behavior. As a result, the proposed scheme is conducted while reducing the annualized cost of the system and utilizing the proposed method. Using modern optimization approaches, the component is sized to achieve the lowest levelized cost of electricity by decreasing the loss of power supply probability. Lastly, the sensitivity analysis is performed to analyze the influence of maximum grid sales and buy capabilities on levelized cost of electricity. The proposed technique's performance is then executed in MATLAB environment and compared to several current methodologies. As a result of the simulation outcomes, the efficiency and performance of the current method are compared to other techniques. According to simulation outcomes, the energy management system (EMS) may lower general expenses by more than 55% and 29% in summer and winter, respectively, while ensuring the satisfaction rate of demand for electric vehicle-charging without knowing the departure times of electric vehicles.

      Abstract: Energy & Environment, Ahead of Print.
      As conflicts between emissions reductions and economic growth intensify, an increasing number of countries and regions are focusing on green total factor productivity (GTFP). Financial agglomeration (QWS), resource endowment (SE), and innovation-driven (ID) are the main factors that cause regional differences in GTFP. However, few scholars have comprehensively considered the impact of the interaction between SE, ID, and QWS on GTFP. This article uses the Global Malmquist-Luenberger (GML) index to calculate the GTFP of 30 Chinese provinces from 2003 to 2020 and constructs a dynamic panel model to present the first comprehensive study of the interactions between SE, ID, and QWS and their relationship with GTFP. The conclusions are as follows. (1) SE is positively correlated with GTFP, which is different from the “resource curse” theory proposed by existing research. (2) There is a crowding-out effect between SE and ID, and their interaction will restrain the growth of GTFP. (3) QWS promotes ID, and the interaction between the two promotes the growth of GTFP. (4) There is a restraining effect between QWS and SE, and their interaction will hinder the growth of GTFP. (5) The key policy directions to improve China's GTFP are to undertake strategic planning from a comprehensive perspective, including encouraging innovation, guiding financial development reasonably, and avoiding excessive consumption of resources.

      An enhanced approach-based grid flexibility analysis for combined heat and power (CHP) systems with variable renewable energy systems is proposed in this article. The proposed system is the combined execution of White Shark Optimizer (WSO) and Pelican Optimization Algorithm (POA). The WSO approach updating behavior is enhanced by the POA approach hence named as enhanced WSO technique. The main purpose of the proposed technique is to provide the optimal grid flexibility by utilizing the CHP systems. Utilizing the proposed method, the demand for the sources is predicted in the year 2030. The proposed approach considers the optimization problem as a reduction of cost and analyzes the flexibility in both upward and downward directions. The sources like photovoltaic, wind turbine, hydropower plants, nuclear, and coal demand power are analyzed. Based on the seasons, the proposed approach analyzed the system flexibility. Finally, the performance of the proposed method is simulated in MATLAB/Simulink platform and the performance is compared to the various existing methods.

      Abstract: Energy & Environment, Ahead of Print.
      Rapid growth in the global population and associated elevated reliance on modern technology has resulted in increased demand for energy consumption. This has resulted in an increased focus on the development and generation of advanced sustainable energy systems. The swift implementation of sustainable renewable energy resource utilization and improvement in their efficiency by the modification of current technologies are the possible solutions that gave rise to the emergence of geothermal technology as a potential alternative. Geothermal technology is a non-carbon renewable energy resource that could be utilized efficiently to fulfil the energy demands while mitigating the climate change threat. According to the surveyed literature, the global geothermal energy power plant installation capacity has reached 14.3 GWe to successfully implement this sustainable alternative. In order to have a successful and uninterrupted way forward, it is essential to evaluate the constraints both in terms of technicality and economic feasibility to establish an approved framework. Moreover, the governance and monitoring regarding the social and environmental impact alongside the legal challenges should also be addressed. The significant barriers include increased capital cost, site selection, superiority of resources at diverse levels of rock bottoms, and obstruction from nearby residents that need to be addressed appropriately. As a result, policymakers will continue to seek measure that have least negative impact on environment.

      Authors: Ge Li, Dao Gao, Xiao Xia Shi
      Abstract: Energy & Environment, Ahead of Print.
      Increasing carbon efficiency is a key path to sustainable development, and information and communication technology (ICT) may help realize a win-win situation for the economy and the environment. However, the existing literature on the impact of ICT on carbon efficiency is relatively shallow. Using a database of Chinese cities, this study empirically explores the role of ICT in carbon efficiency from the aspects of direct impact, mediation effect, and threshold effect. Results show that ICT significantly improves the carbon efficiency represented by single-factor and total-factor carbon efficiency. The mediation effect indicates that technological innovation, industrial structure upgrading, and external openness are effective ways for ICT to play its role. The threshold model shows that the promoting effect between the two depends on the local institutional environment. Further heterogeneity analysis shows that ICT plays a more remarkable role in promoting carbon efficiency in eastern regions. This study provides evidence for aggressively digitizing economies to shift towards a low-carbon economy. Policymakers are encouraged to consider better integrating ICTs into sustainable development strategies.

      Authors: Jun Zhang, Samia Khalid, Hamid Mahmood
      Abstract: Energy & Environment, Ahead of Print.
      Due to the rapid increase in industrialization, environmental degradation has recently grown into a serious problem. The existing literature has mostly focused on the reduction of CO2 emissions and ignored PM2.5 emissions, which have a direct impact on the environment through air quality. Therefore, this study attempts to look into the effectiveness of environmental policies in determining environmental sustainability by lowering PM2.5 emissions in the Organization for Economic Cooperation and Development (OECD) countries. These are categorized as fiscal (green taxes), economic incentives, and research and development (R&D) investment policies. The second-generation panel co-integration method and Cross-Sectionally Autoregressive Distributed Lag (CS-ARDL) are employed for the period 1990–2019 to estimate the results. The Westerlund cointegration results confirmed a stable, long-run relationship between all the variables. The study shows that not all environmental regulations are equally successful in lowering PM2.5 emissions. According to the findings, R&D and fiscal policy help reduce PM2.5 emissions, whereas economic incentive strategies and population increase them. This shows that establishing green taxes on these emissions and developing green R&D policies will facilitate environmental sustainability. The overall findings let us classify some good performances in the OECD countries regarding the design of environmental policies, even though we should also keep in mind that there isn’t a solution that works for everyone. Policy makers should modify their plans in accordance with the nature and unique features of their country or region.

      Abstract: Energy & Environment, Ahead of Print.
      The pursuit of decarbonization has created an awareness globally in relation to geothermal energy, either for electricity generation or direct usage, since fuel combustion is not needed. Premised on this intriguing detail, this present research scrutinizes the impact of geothermal energy on CO2 emissions in the top seven geothermal energy-consuming nations. Using the quarterly dataset of geothermal and CO2 emissions stretching over the period between 1990 and 2019. The quantile-on-quantile (QQ) approach, which considers the conventional quantile analysis and nonparametric, is utilized in this research to provide more accurate and robust estimations. Furthermore, the QQ approach differentiates the impacts of geothermal energy on CO2 emissions into three quantiles: upper, medium, and lower. Additionally, the nonparametric causality-in-quantiles is used to evaluate the causation in quantiles between geothermal and CO2 emissions. From the outcomes of the QQ approach, we discovered that in several quantiles, geothermal energy mitigates environmental deterioration, wherein CO2 emission is reduced in Italy, Mexico, and New Zealand. However, geothermal energy boosts CO2 emissions in India, the USA, Turkey, and the Philippines. Furthermore, the nonparametric causality-in-quantiles discovered that geothermal energy predicts CO2 emissions in all nations.

      Abstract: Energy & Environment, Ahead of Print.
      The impact of green investment on green ecological development is still controversial. Based on the provincial panel data from 2009 to 2020, this study uses a spatial econometric model to test the impact of green investment on green ecological development and regional differences. Results found that the green investment significantly improved the local green ecological level and had less impact on the green ecological level of surrounding areas. Green innovation significantly affects green investment to promote green ecology in local and surrounding areas, inhibiting the development of green ecology. Environmental regulation improved the effect of local green investment to promote green innovation and has an inhibitory effect on surrounding areas. Moreover, environmental regulation inhibits the effect of local green investment to promote a green ecology. Finally, the promotion effect of green investment on local green ecology is only significant in the eastern region. The effect in the western region is not significant. This study has important practical significance for promoting China's green ecological development.

      Abstract: Energy & Environment, Ahead of Print.
      Under the double pressure of economic downturn and climate deterioration, the Chinese government needs to use the “double carbon” policy to drive the green transformation of the manufacturing industry. This article takes A-share manufacturing listed companies as the research object, constructs the enterprise digital economy investment index by text analysis and expert scoring method, and represents the degree of green transformation by enterprise green total factor productivity. At the theoretical level, the impact mechanism of the digital economy empowering green transformation in the manufacturing industry is hypothesized. The relevant hypotheses were tested through econometric empirical evidence, and the econometric model significantly passed the robustness test, proving that the digital economy empowers the development of green transformation in the manufacturing industry significantly. This article reveals that the digital economy promotes the green total factor productivity of enterprises by enhancing their innovation capability, improving the efficiency of production factor flow, and increasing their emission costs, but the factor intensity and the nature of enterprise owners will have different effects on the green transformation of the manufacturing industry enabled by the digital economy. This article explores the internal mechanism of green transformation development in the digital economy-enabled manufacturing industry and provides empirical evidence for enterprises to formulate development strategies and for governments to issue guiding policies.

      Abstract: Energy & Environment, Ahead of Print.
      Although available statistics reveal Africa as an insignificant contributor to the devastating global climate condition, the succeeding impacts seem to hit the region harder than others. Efforts to address the environmental issues have seen the transition from carbon-intensive to carbon-abating sectors. Hence, this study makes the first empirical attempt to probe the ecological effects of structural transition and demographic mobility amidst the presence of technological innovation, foreign direct investment, and renewable energy. The empirical evidence focuses on the five highest emitters in Africa from 1990 to 2019 using advanced estimators, including cross-sectional autoregressive distributed lag (CS-ARDL), augmented mean group (AMG), common correlated effect mean group (CCEMG), and method of moment quantile regression (MMQR). For easy tracking of emanating effects, structural transition is captured by agriculture, manufacturing, and service sectors’ value added, whereas demographic mobility vectors rural and urban population. The results reveal agriculture sector, manufacturing sector, rural population, and urban population as amplifiers of CO2 emissions. Conversely, the moderating roles of technological innovation amidst service sector, foreign direct investment, and renewable energy are confirmed. Besides, Granger causality uncovers unidirectional and bidirectional causality in the model. Promoting developments in research and development and adopting carbon tax policies are among the emanating policies on the findings.

      Abstract: Energy & Environment, Ahead of Print.
      The 3D sand printing (3DSP) technology provides a richer realization path for the sustainable development of the manufacturing industry. It has the advantages of one-time molding, reducing design constraints and machining amount, and easy control of casting dimensional accuracy. Therefore, studying the impact of process parameters of the printing process on printing efficiency, resource consumption, and carbon emissions is the basis for the sustainable development of 3DSP technology. In this paper, starting from the main influencing parameters such as printing layer thickness, recoater speed, printing angle, and single printing quantity, a relationship model between printing parameters and carbon emission sources is constructed. A total factor carbon emission prediction model of 3DSP process including the impact of capital and labor is established. Build an influence relationship with printing parameters as independent variables and carbon emissions as dependent variables. Taking the sand casting industry as an example to verify the above model, the experimental results show that the thickness of the printing layer has the greatest impact on carbon emissions. When the layer thickness is 0.36 mm, the speed of the recoater is 0.22 m/s, the printing angle is (0°, 0°, 90°), and the single print quantity is 84, the total carbon emission is the lowest and 28.77% less compared to the parameter with the highest carbon emission. The average relative error of the predictive model is 1.929%. The results of this study can provide some new ideas for sustainable development of additive manufacturing technology.

      Abstract: Energy & Environment, Ahead of Print.
      The present era is facing a dilemma relating to engaging the essentialities of energy resources to attain economic prosperity due to the ensuing environmental complications. Consequently, sectors such as transport, aviation, and refining industries are under the scrutiny of reducing their reliance on fossil fuels achievable with the promotion of hydrogen energy which is largely neglected in the environmental empirics. To this end, the environmental impacts of green hydrogen in the top seven hydrogen-consuming countries are assessed from 1995 to 2019. Moreover, the roles of green finance, environmental-related technologies, energy efficiency, and digitalization are considered in the model specified within the STIRPAT framework. Second generation estimators comprising cross-section autoregressive distributed lag, Common Correlated Effect Mean Group, Augmented Mean Group, and Method of Moment Quantile Regression are employed in evaluating the stated hypotheses. Feedbacks from the analysis uncovered that green hydrogen; green finance, environmental-related technologies, energy efficiencies, digitalization, and structural change promote environmental sustainability in the top seven hydrogen-consuming countries. Contrariwise, natural resource dependence and urbanization trigger CO2 emissions, thereby exacerbating environmental complications. Based on the findings, policy measures leading toward sustainable environment are suggested.

      Authors: Kizito Uyi Ehigiamusoe, Hooi Hooi Lean, Sotheeswari Somasundram
      Abstract: Energy & Environment, Ahead of Print.
      The mounting level of environmental degradation in Malaysia constitutes a grave issue to analysts and policymakers because it has adverse impact on climate change and human lives. This study is motivated by the dearth of a comprehensive research on the environmental impact of sectoral growth. It focuses on sectoral growth because of the need to strike a balance between the economic and environmental impacts of the agricultural, industrial, and financial sectors in Malaysia. Therefore, this study analyses the environmental impacts of the agricultural, industrial, and financial sectors in Malaysia during 1980–2018. It uses ecological footprint and carbon emissions as indicators of environmental degradation to properly capture various aspects of environmental degradation. It employs the Environmental Kuznets Curve (EKC) model and Autoregressive Distributed Lag (ARDL) procedure. This study contributes to the extant literature by showing that the agricultural, industrial, and market-based financial sectors aggravate carbon emissions while the bank-based financial sector mitigates carbon emissions in Malaysia. However, the impacts of the agricultural, industrial, and financial sectors on ecological footprint are tenuous. Though the EKC hypothesis is verified, energy consumption worsens ecological footprint and carbon emissions. The findings are robust to structural breaks and satisfactory diagnostic tests. This study implies that the agricultural, industrial, and financial sectors are significant determinants of carbon emissions. Since Malaysia cannot afford to sacrifice sectoral development for environmental sustainability, it is necessary for stakeholders to embrace environmental-friendly techniques that can boost sectoral development without compromising environmental quality.

      Authors: J Charles Rajesh Kumar, MA Majid
      Abstract: Energy & Environment, Ahead of Print.
      While solar power projects are built on a continuous ground, wind power projects require scattered land, raising transmission costs and increasing the risk of land-related complications. Wind–solar hybrid (WSH) projects have been proposed to address these issues and accelerate installation. WSH power projects will create a well-defined area with sufficient infrastructure, including evacuation facilities, where the project’s risks can be reduced. The extensive coastline of India is endowed with high wind flow speed and plentiful solar power resources, creating an ideal environment for WSH projects to prosper while simultaneously improving grid stability and reliability. WSH plants guarantee higher transmission efficiency and cost-effectiveness than their stand-alone counterparts. As of 30.11.2021, 3.75 GW of WSH projects have been granted, with 0.148 GW of operational capacity and 1.7 GW of WSH projects in various bidding phases. In this paper, we discussed state-wise WSH potential, the key players in the WSH project, the National WSH, and the State WSH policy and amendments. Also, the WSH project’s physical progress and commercial details are covered. A feasibility study of the WSH plant is performed, and the primary design strategy for deploying WSH power facilities in India is discussed. It covers every step of this process, from design technique to choosing and evaluating potential locations for such hybrid projects, optimally placing wind turbines and solar panels, overall capacity mix for hybrid plants, and ultimately power evacuation optimization. Additionally, a brief study of the savings from these hybrid plants and the environmental, social, and governance standards which are necessary to implement these projects are provided. The potential challenges connected with WSH technologies are examined in depth, and potential solutions and mitigations for the challenges are provided. Designing a WSH for small-scale irrigation is provided along with the size and choice of wind and solar systems. Degradation of PV systems and carbon savings are included, along with some policy measures to boost the proportion of WSH in the entire power mix. In India, the development of large-scale WSH projects is still in its early stages, and more research is required to explore technical, commercial, and policy elements that influence project design. The policy suggestions for improvement of the WSH project are provided. The WSH project developers, potential investors, stakeholders, innovators, policymakers, manufacturers, designers, and researchers will benefit from the recommendations based on the review’s findings.

      Abstract: Energy & Environment, Ahead of Print.
      The excessive growth of carbon emissions (CO2E) from industrial energy use not only exacerbates global warming and severely curbs the sustainable development of the economy and society. As a high energy-consuming sector second only to the fossil energy division, the power and heavy division, China's chemical industry should have received more attention for its CO2E. However, there are limited literatures on energy CO2E in China's chemical sector at present. Based on this fact, this current paper uses the energy utilization approach, the input–output analysis approach, and the extended structural decomposition method to evaluate the energy-related CO2E of China's chemical sector from 2007 to 2017. (1) China's chemical sector energy-related CO2E showed a trend of first growth and then a slow decline, demonstrating that the rapid growth of China's chemical sector energy-related CO2E has been effectively controlled; However, it should be noted that the chemical industry is still dominated by high-CO2E energy-related CO2E at the current stage. (2) Input structure and energy intensity effects have a reduced influence on the growth of energy-related CO2E in China's chemical sector. This is due to upgrading energy use technology and optimizing the generalized technology progress rate in the chemical sector. (3) Energy structure and final demand effects have encouraged the growth of the chemical sector's energy-related CO2E. It shows that the industrial system's demand for chemical products is constantly expanding, and the chemical products still have the characteristics of high carbonization. Also, the chemical sector's supply-side energy utilization structure has not been significantly enhanced.

      Abstract: Energy & Environment, Ahead of Print.
      Light pollution in recent years has drawn surging public concerns in Hong Kong. The improper management of the light sources causes pollution, particularly light trespass on the community level, which obstructs the residents. Yet more studies are expected to quantitatively and systematically assess the severity of the artificial light trespass problem, and to offer practical solutions for mitigation and urban management. This study was conducted on a typical high-density, mixed-use neighbourhood in Tsim Sha Tsui district. The study consists of on-site measurement and model simulation. Three illuminance measurements were conducted to evaluate the impact of light pollution on the streets and light trespass on the nearby buildings. It was found that the impacts on the buildings (mean illuminance of 3 lx) are less significant than on the streets (mean illuminance of 188 lx) for the target study area. Indoor measurement at various height levels showed a mean illuminance level of 0.6 lx, which is much lower than the international limit of 25 lx. Meanwhile, the modelling work, consisting of correlation, verification and regression analysis, was carried to bridge luminous flux from light sources and illuminance received at the target. A three-dimensional (3D) model was developed to mimic the actual situation and was used to identify the primary light sources causing impacts. While a growing number of research is found on measuring and modelling the intricate light pollution in such a micro scale that elevates explicitly the importance of extrapolating the light pollution effect vertically from street level to building level, direct simulation is still lacking. This study also refined and summarised the research methodology to serve as a feasible and organised protocol for setting up the measurement and modelling work. This can be adapted in future assessments on light trespass issues under similar circumstances elsewhere, like scientific research, urban planning, or property development projects.

      Abstract: Energy & Environment, Ahead of Print.
      This study examines the long-run impact of coal usage decline from a disaggregated energy consumption perspective by considering the role of coal usage on carbon dioxide (CO2) emissions and economic growth. For this purpose, the study focuses on China and India as the leading coal-user countries; considers coal, oil, natural gas, and renewable energy consumption as explanatory variables; uses yearly data from 1990 to 2021, and applies a novel dynamic autoregressive distributed lag (DYNARDL) simulations. Also, the Kernel-based regularized least squares (KRLS) approach is performed for robustness checks. The outcomes show that (i) there is cointegration between coal usage and CO2 emissions, and between coal usage and economic growth in the long run; (ii) coal usage is the most important indicator among explanatory variables; (iii) coal usage has a statistically significant impact on CO2 emissions in both China and India; (iv) however, coal usage is not significantly effective on economic growth for both China and India based on DYNARDL simulations; (v) negative counterfactual shocks in coal usage have a decreasing impact on CO2 emissions; (vi) KRLS results show that coal usage has a causal impact on CO2 emissions and the results of the DYNARDL simulations are robust. Hence, counterfactual shocks present important insights about the future impacts of coal usage decline on both CO2 emissions and economic growth. Based on the empirical results, policy implications, such as decreasing the amount of coal usage on and increasing the amount of alternative energy sources in the total energy mix, are also proposed.

      Authors: Arshad Ali, Magdalena Radulescu, Daniel Balsalobre-Lorente
      Abstract: Energy & Environment, Ahead of Print.
      This study aims to examine the linkages between renewable energy consumption (REC), nonrenewable energy consumption (NREC), carbon dioxide (CO2) emissions, and economic growth in emerging Asian countries during the period 1975–2020 using a panel augmented mean group (AMG) estimation technique. The results of the long-run coefficient elasticity show that REC, NREC, employed labor force, and capital formation contribute significantly to long-run economic growth. The research analysis also found that NREC significantly increases long-term carbon emissions while REC significantly reduces long-term carbon emissions. Moreover, gross domestic product (GDP) and GDP3 have a significant positive impact on environmental degradation while GDP2 has a significant adverse impact on environmental pollution, thus validating the N-shaped Environmental Kuznets Curve (EKC) hypothesis in selected emerging Asian economies. The country-wise AMG strategy points out that India and Bangladesh have no EKC hypothesis, China and Singapore have an inverted U-shaped EKC hypothesis and Japan and South Korea have an N-shaped EKC hypothesis. Empirical evidence from Dumitrescu and Hurlin's causality test shows a two-way causality between REC and economic growth, supporting the feedback hypothesis. Strategically, this study suggests that more renewable energy is a viable strategy to address energy security and reduce carbon emissions to protect the environment and boost future economic growth in selected emerging Asian countries.

      Authors: Jiafeng Gu
      Abstract: Energy & Environment, Ahead of Print.
      Declining levels of social welfare caused by climate warming and air pollution place increasing constraints on high-quality, sustainable global development. To achieve global climate-governance goals, it is essential to accelerate the process of peaking carbon emissions and meeting air-quality standards. Despite growing awareness of the impact of low-carbon city policies on the environment, few studies have focused on their impact on urban air quality. Based on panel data drawn from 275 cities between 2011 and 2017, the present study evaluates the effects of a low-carbon city policy on urban sulfur-dioxide emissions, using the low-carbon city policy as a quasi-natural experiment. The findings reveal that urban sulfur-dioxide emissions have obvious spatial-autocorrelation characteristics, showing obvious spatial clustering. The low-carbon city policy not only significantly reduced urban sulfur-dioxide emissions in pilot cities, but also suppressed sulfur-dioxide emissions in surrounding cities through an indirect rebound effect. This paper provides a theoretical reference for collaborative governance, which can help to achieve peak carbon emissions and air-quality standards. To reach those goals, nations must abandon territorial prevention-and-control methods based on administrative divisions and to fully activate cross-city regional joint prevention-and-control measures. This study proposes key policies, including promoting inter-city regional coordination mechanisms, strengthening the collaborative governance in relation to carbon-dioxide and sulfur-dioxide emissions, and promoting the construction of inner-city green facilities.

      Abstract: Energy & Environment, Ahead of Print.
      Energy efficiency offers a vast, low-cost energy resource for the economy, but only if the nation can craft a comprehensive and innovative approach to unlock it. One of the most viable options is to invest in energy productivity. This study examines the asymmetric and long-run effects of energy productivity on environmental degradation while controlling for renewable energy, economic growth, and financial development, utilizing the nonlinear autoregressive distributive lag model and other robust econometric techniques in the United Kingdom during the period 1990Q1–2020Q4. The United Kingdom is one of the world's wealthiest countries; its environment is being severely strained and is challenged in boasting massive investments to reduce CO2 emissions to 78% by 2035. Given the important scenarios for energy efficiency, this study outcome indicates that (a) energy productivity has been beneficial for reducing carbon emissions; (b) renewable energy sources significantly mitigate carbon emissions in the United Kingdom, and (c) economic growth and financial development cause to increase carbon emissions in the United Kingdom. Given the findings, some policy recommendations abound. The negative statistically significant coefficient of renewable energy is an indication that the expansion of renewable energy is essential to achieving clean and sustainable growth. Furthermore, policymakers should enact new environmental laws that prioritize R&D and embrace cleaner technologies.

      Abstract: Energy & Environment, Ahead of Print.
      Polyaniline (PANi) reinforced with graphene oxide (GO) composites were synthesized via in-situ polymerization. The GO was synthesized from natural graphite flakes via the modified Hummer's method. The PANi/GO composites were characterized by Raman spectroscopy, X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, and thermogravimetric analysis. The composites were used as supercapacitor electrodes and the performances were measured by the specific gravimetric capacitance (Csp) from cyclic voltammetry and charge/discharge characteristics. The maximum value of [math] was recorded as 36 F/g at a current density of 1 A/g for a loading of 50 wt.% of GO. However, the maximum energy density and power density were recorded as of 2.28 Wh kg−1 and 259.06 W kg−1, respectively, for the loading of 10 wt.% of GO. Additionally, the PANi/GO exhibited the highest capacitance retention of about 76.96% after 5000 cycles at a current density of 1 A/g. The electrochemical performance of the PANi/GO composites was suitable to be used for energy storage devices application.

      Abstract: Energy & Environment, Ahead of Print.
      Well-designed environmental regulations are a prerequisite for achieving green economic growth. However, the effectiveness of campaign-style environmental regulation—a widely used environmental management instrument in developing nations or even in some developed nations, on green economic growth remains under-researched and has not reached a consistent conclusion. This paper takes advantage of China's Central Environmental Protection Inspector policy—the strictest and largest campaign-style environmental regulation policy in China's history, as a natural experiment and uses the difference-in-differences method to explore the effect of campaign-style environmental regulation on green economic growth, and further analyze its underlying mechanisms and heterogeneity effects. The panel data covering 280 prefecture-level cities in China from 2009 to 2019 are used. Our results show that Central Environmental Protection Inspector can result in an average of 14.2% increase in green economic growth, and this effect is sustainable for a long time. Mechanism analysis shows that Central Environmental Protection Inspector boosts green economic growth mainly by promoting green innovation and optimizing industrial structure. Further heterogeneity analysis reveals that the positive effect of Central Environmental Protection Inspector on green economic growth is greater in eastern China and underdeveloped cities.

      The main objective of the current study is to analyze the nexus between public debt, renewable electricity, economic growth, and carbon dioxide (CO2) emissions in emerging economies between 1990 and 2020. The augmented mean group (AMG), fully modified ordinary least square (FMOLS), and dynamic ordinary least square (DOLS) models have been applied to analyze the long-run estimation. The empirical evidence demonstrates that public debt, renewable electricity reduces CO2 emissions. Furthermore, an N-shaped relationship has been identified between per capita CO2 emissions and per capita GDP in emerging nations. Also, the result reveals a bidirectional causal relationship between public debt and economic growth, CO2 emissions and economic growth, public debt and CO2 emissions, and renewable electricity and economic growth. The current study recommends promoting the renewable energy transition, elevating renewable electricity generation capacities, and ensuring greener economic growth by emitting carbon dioxide emissions across emerging countries. The government across each region could incorporate taxes and other incentives to encourage entrepreneurs and citizens to produce equipment that reduces carbon intensity and is ecologically friendly.

      Abstract: Energy & Environment, Ahead of Print.
      In the context of global climate change, improving agricultural carbon productivity is an important channel to cope with climate change, reduce agricultural carbon emissions and maintain agricultural growth. For a long time, agricultural development in China mainly depends on the government's fiscal expenditure. However, does fiscal support helps to promote carbon productivity of agriculture' This question remains to be answered. Using a set of panel data covering 31 provinces and cities from 2003 to 2019, this study empirically explores the impact of agricultural fiscal support on agricultural carbon productivity in China. Benchmark regression results indicate that after controlling other influential factors, regional fiscal expenditure on agricultural has a significantly positive impact on agricultural carbon productivity. In addition, the promotion impacts of fiscal support on agricultural technological innovation and scale operation efficiency are two effective channels by which to help promote agricultural carbon productivity. By using a panel threshold regression model, we find that there exists a nonlinear relationship between fiscal support and agricultural carbon productivity. The input of agricultural machinery and chemical fertilizer are two threshold variables. Further, this causal linkage between fiscal support and agricultural carbon productivity exists differences because of the different levels of agricultural carbon productivity and regions. Our research provides Chinese theoretical basis and practical reference for improvement of agricultural carbon productivity from the perspective of fiscal expenditure.

      Abstract: Energy & Environment, Ahead of Print.
      The output energy produced by the photovoltaic system strongly depends upon the amount of solar radiation harvested by the photovoltaic panels. Varying the tilt of photovoltaic panels at the optimal angle and/or cleaning the photovoltaic panels at regular intervals are some of the techniques that could enhance the photovoltaic system performance albeit at the cost of increased labor and water budget. Here, we explore a farm-level study to investigate the effect of different tilt angle adjustment schedules on the performance of conventional north/south ([math]) tilted monofacial photovoltaic farms. We further compare the performance of optimally tilted [math] photovoltaic farms with that of east/west ([math]) faced vertical bifacial photovoltaic farms for various dry periods for Lahore, Pakistan. We show that for a dry period of one month, the performance of [math] tilted farm is decreased by [math]40 kWh/m[math] as compared to that for [math] farm that exhibits a performance degradation of [math]3 kWh/m[math]. Further, [math] farm performs better than [math] vertical farm if the cleaning is performed on (or before) fortnightly basis. Further, if cleaning is delayed for one month, then [math] vertical farm performs better than [math] tilted farm. The results presented in this work are beneficial for the development of [math] faced vertical bifacial farm in dusty climates and regions with scarce water supply.

      Authors: Nahyeon Lee, Byungmin Ahn, Jechan Lee
      Abstract: Energy & Environment, Ahead of Print.
      Acrylate polymer is widely used to manufacture display films as an adhesive. Improper disposal of acrylate polymer-containing display film waste (a kind of E-waste) may cause serious environmental problems. As an effort to develop a display film waste treatment strategy, this study applied a solvent-based method to recover acrylate polymer from display film waste. The solubility of acrylate polymer (e.g. poly(tert-butyl acrylate)) in 18 different organic solvents was calculated using Hansen solubility parameters. As a result, 2-butanol and methyl acetate were chosen as organic solvents for the acrylate polymer recovery from the display film waste. Effects of various recovery parameters (e.g. temperature, time, and stirring speed) on the recovery of acrylate polymer in five different solvent systems consisting of 2-butanol and methyl acetate (2-butanol, methyl acetate, 1:1 mixture, 1:2 mixture, and 2:1 mixture) were explored. 2-Butanol was found to be a better solvent than any others because it is more hydrophobic than methyl acetate. The recovery condition at which the highest acrylate polymer recovery yield in 2-butanol was obtained was T  =  30 °C, t  =  1 h, and stirring speed of 250 r/min, reaching 8.28 wt%. This study would help to develop an E-waste recycling method that can be recovering value-added products from E-waste.

      Abstract: Energy & Environment, Ahead of Print.
      The intensification of ecological issues provokes to search for the appropriate mechanism and resources to solve them without declining the economic growth. This requires moving from resources oriented to green economic development. It could be realised through two goals: achieving macroeconomic stability – core driver of economic growth; declining environmental degradation and increasing efficiency of resources using – core requirements for green development. The paper aims to check the hypothesis on macroeconomic stability's impact on the green development of the countries. The object of investigation is European Union countries from 2000 to 2020. The study applied the following methods: the Global Malmquist-Luenberger productivity index – to estimate the green development of the countries; Macroeconomic Stabilisation Pentagon model – to estimate macroeconomic stability; Kernel density estimation and Tobit model – to check the macroeconomic stability impact on the green development of the countries. The empirical findings show that Malta from the ‘Green Group’ and Estonia from the ‘Yellow group’ have the highest value of green development, and Sweden and Greece have the highest value of macroeconomic stability. Besides, the findings allow confirming the research hypothesis. Thus, the growth of external dimensions of macroeconomic stability by 1 point led to the growth of green economic development by 0.085 (among ‘Green group’) and 0.195 (among ‘Yellow group’). It confirms that harmonising macroeconomic stability among all EU members allows for achieving the synergy effect.

      Abstract: Energy & Environment, Ahead of Print.
      Based on the fact that the EU-part of the Eastern Bloc has not fared well in transitioning to renewable energy in the last decade compared to other regions of the bloc, this study investigated the impacts of coal consumption, socioeconomic factors and bureaucracy on the environment and the moderating effect of socioeconomic factors and bureaucracy on the coal consumption–environment relationship in the selected bloc. The study used the AMG, FMOLS and DOLS modelling framework and a panel of six countries in the selected bloc from 1990 to 2018. The study established that coal consumption has a significant dampening effect on CO2 emissions in the EU-part of the Eastern Bloc and that bureaucracy in the region amplifies this effect instead of mitigating it. In another corridor, we found that in the midst of the coal–environmental nexus, socioeconomic factors offer a mitigating path towards emission reduction in the region. Policy recommendations directed at addressing bureaucratic hitches associated with the transition to renewable energy in Eastern Europe. The authors propose the inauguration of hybrid courts (specialised) to settle disputes that may arise from indigenes and standing technical committees to increase bureaucratic expertise, which would reduce the permit acquisition period required for wind, hydropower, and solar installation farms and other technicalities associated with the EU funding for the Eastern Bloc.

      Abstract: Energy & Environment, Ahead of Print.
      The study analyzes the asymmetric nexus of coal consumption with environmental quality and economic growth. In this context, the study focuses on eight leading emerging countries that take place in BRICS, E7, and Fragile Five groups. Also, the study uses yearly data from 1989 to 2021 and performs novel quantile methods, such as Granger Causality-in-Quantiles and Quantile-on-Quantile Regression (QQR). Also, quantile regression is used for robustness check. The results present that (i) there are causalities from coal consumption to both environmental quality and economic growth at 10% significance, whereas quantile and country-based results differ; (ii) effects of coal consumption on environmental quality are much stronger in lower quantiles for Brazil, Indonesia, India, South Africa, and, Turkey, but in higher quantiles for China, Mexico, and Russia; (iii) effects of coal consumption on economic growth are much stronger in lower quantiles for Brazil, Indonesia, India, Russia, South Africa, and Turkey; in higher quantiles for China; lower and middle quantiles for Russia; and all quantiles for Mexico; and (iv) the robustness of the QQR results are validated. Hence, empirical outcomes underline the highly crucial effects of coal consumption on environmental quality and economic growth in the countries. The results imply that policymakers should focus on efforts to decrease coal consumption gradually by applying a macro transition plan to increase environmental quality without causing economic decline by considering changing effects of coal consumption at quantiles and countries.

      Authors: YunQian Zhang, Li Li, Muhammad Sadiq, FengSheng Chien
      Abstract: Energy & Environment, Ahead of Print.
      A high level of carbon dioxide (CO2) emission has become a global issue due to extensive production and energy usage that needs regulators’ attention and researchers’ emphasis. Hence, the study aims to explore the effectiveness of energy production and usage on carbon dioxide emission in China. The current study has taken the electricity production from oil, coal and nuclear as the measurement of energy production, while fossil fuel energy consumption and energy use have been taken as the measurement of energy usage, and energy import has been taken as the control variable. The secondary data has been gathered using a secondary source like World Bank from 1991 to 2020. The Quantile Autoregressive Distributed Lag (QARDL) was employed by the study to examine the linkage among variables, while the Augmented Dickey–Fuller (ADF) test was adopted to check the stationarity. The results revealed that electricity production from oil, coal and nuclear has a positive connection with CO2 emission. The findings also exposed that the FFEC, energy import, and energy use also have a positive linkage with CO2 emission. This study monitors the policymakers while establishing regulations to control CO2 emissions by limiting the country's energy production and usage.

      Authors: Ching-Chi Hsu
      Abstract: Energy & Environment, Ahead of Print.
      The economic development of any nation depends on energy production and consumption, thereby, needing more exploration from researchers. The current article thus makes an attempt to examine the role of REW and non-REW energy on the economic development in China. The current article has used renewable energy production (REP), and renewable energy consumption (REC) to measure renewable energy. The current research has used fossil fuel energy consumption, energy use, energy import, and electric power consumption to measure non-renewable energy. The present study has taken secondary data from world development indicators from 1986 to 2020. The article has applied the nonlinear autoregressive distributed lagged model to evaluate the association among the understudy constructs. The findings indicated that REP and REC, fossil fuel energy consumption, energy use, energy import, and electric power consumption are linked with economic development in a positive manner in China context. The study guides the regulators in establishing the regulations related to economic development through both type of energy resources.

      Abstract: Energy & Environment, Ahead of Print.
      China, the world's largest developing country, faces a severe water shortage. As the government has set a goal of limiting water use to 7000 × 108 m3 by 2035, how to control the increase in water use will be a thorny issue for China. Unbalanced and uncoordinated regional socio-economic development is an important feature of China. Research on the interaction between provincial water use will help to optimize the rational allocation of water resources and control of water use. In this paper, SNA (social network analysis) method is first used to explore the characteristics of social network relationship between inter-provincial water use, construct a two-stage model of SNA–LMDI, and decompose the driving factors of inter-provincial water use evolution. We found the following points. (1) From 2000 to 2018, the spatial correlation network structure of water use is tending to be stable, and the stability and risk resistance of the whole network are enhanced. (2) From different angles to quantify the centricity analysis, can be found that eastern provinces located right in the heart of water network, obviously larger impact on water resources utilization in other provinces, Shanghai and Beijing is located in the former two, and central and western provinces in the edge position. (3) The national water use spatial correlation network can be divided into four blocks, net beneficial block, bidirectional spillover block, brokers block, and net spillover block. (4) Technological progress and industrial structure adjustment were the primary and secondary factors inhibiting the increase of total water use, while income increase was the main factor promoting the increase of total water use, population scale expansion had a weak role in promoting the increase of total water use. Some policy implications are put forward related to our research conclusions.

      Abstract: Energy & Environment, Ahead of Print.
      The acceleration of ecological footprint and trade openness are two major hot subjects that have received much attention in recent years. Thus, the current study evaluates the interrelationship between ecological footprint and trade openness in Mexico, Indonesia, Nigeria, and Turkey (MINT) nations. The study utilized time series and panel analysis between 1961 and 2018. The research provides thorough information regarding this relationship for various time and frequency sub-periods by employing the partial wavelet, wavelet coherence, and multiple wavelet coherence techniques. The results from the wavelet coherence show that in the short and medium term, there is significant co-movement between ecological footprint and trade openness for Mexico and Indonesia, with trade openness driving ecological footprint positively at high and medium frequencies. Moreover, at all frequencies, trade openness drives ecological footprint positively for Nigeria and Turkey. The study validates that trade openness leads to the ecological footprint hypothesis in each nation. Furthermore, the multiple and partial wavelet coherence undoubtedly strengthens the occurrences spotted through the wavelet coherence in each nation. Based on these findings, policy recommendations are put forward.

      Authors: Minhaj Ali, Shujahat Haider Hashmi, Yasir Habib, Dervis Kirikkaleli
      Abstract: Energy & Environment, Ahead of Print.
      The present study investigates the effect of public–private partnership investment in energy and renewable energy consumption on carbon dioxide (CO2) emissions, taking into account the critical role of economic growth and trade openness in Pakistan from 1992 to 2019. The linear and nonlinear autoregressive distributed lag models are employed to check the co-integration link between dependent and independent variables, further estimate short-run and long-run associations, and examine the symmetric and asymmetric effects of public–private partnership investment in energy on CO2 emissions in Pakistan. The empirical findings show that public–private partnership investment in energy reduces environmental quality by increasing CO2 emissions. Similarly, economic development and trade openness harms the atmosphere by raising CO2 emissions. On the other hand, renewable energy consumption significantly negatively affects CO2 emissions. In addition, the findings also authenticate the asymmetric link between public–private partnership investment in energy and the environment, as CO2 emissions are caused mainly by positive shocks in public–private partnership investment in energy in the short and long run. This study proposes financing renewable energy projects through public–private partnership is needed for an environmentally friendly future.

      Authors: Hong Eun Moon, Si Won Choi, Yoon Hee Ha
      Abstract: Energy & Environment, Ahead of Print.
      This study investigates the factors that affect the investment environment of the renewable energy industry in emerging countries, and quantifies them to derive relative priorities, drawing on the Vietnamese solar market as a critical case. Vietnam's solar photovoltaic (PV) market was exposed to various adverse policy situations during 2017–2019. The priorities of the determinant factors were derived using analytic hierarchy process analysis, based on a survey of 20 energy experts. The priority of the factors in Level 1 include, in descending order, policies, legal framework, profitability, ease of access to finance, infrastructure, and external factors. The top five of the 29 important factors in Level 2 are level of policy implementation, policy consistency (predictability), feed-in-tariff price, incentives and subsidies for foreign (direct) investment in solar PV, fruitage remittance, and transmission/distribution lines. We demonstrate that the active establishment and implementation of policies is crucial for the development of the renewable energy market. The improvement of the grid infrastructure and measures for system integration should be supported in accordance with solar power deployment. Therefore, actively engaging the interests of various stakeholders comprehensively and in a balanced manner during policymaking can be decisive in supporting stable market growth, facilitated by partnerships between local developers and international investors.
