Abstract: Energy & Environment, Ahead of Print.
Concern about climate change has drawn out the numerous influences of human activities on the environment. However, the role of migration in environmental quality has been conspicuously silent in the literature despite the increasing rate of cross-country migration. As the energy transition progresses, it is important to examine the interplay between migration, renewable energy, income, and environmental quality in 33 advanced countries using the latest dataset. With data from 2010 to 2023, the study applies the non-additive panel quantile regression to two models with different interaction terms. Results show asymmetric migration impacts on environmental degradation, while the effects of globalization are mostly negative. Renewable energy only reduces environmental degradation at higher levels. However, renewable energy development reduces the impact of migration for most quantiles, while income increases the impact of migration throughout. The study implies that policies might influence how migration will affect the environment. Income-related activities are channels through which migration affects environmental degradation, but clean energy development is a sustainable policy against climate change regardless of population gains. Therefore, dividends of migration can be drawn to increase capacity in green technology through increased green finance, innovations, research, and development, thereby resulting in green economic growth.

Abstract: Energy & Environment, Ahead of Print.
Climate change, caused by the burning of fossil fuels, has emerged as an acute world problem, especially in the Group of Twenty (G20), where CO2 emissions and other greenhouse gases are accumulating. This research examines how energy consumption, digitization, internationalization, and green finance affect the environmental sustainability of G20 countries in 2004–23. It also discusses how green technology innovation mediates these relationships. The research-based analysis of World Development Indicators and Organization for Economic Cooperation and Development data employed static panel data, fixed-effects models, and STATA software for econometrics. The findings also reveal that the four variables, namely green finance, digitalization, globalization, and energy consumption, significantly and positively correlated with environmental sustainability. It was also revealed that green technology innovation has a significant, although negative, impact on mediating these factors. Logically, these outcomes point to the fact that, as much as green technology innovation is crucial, the integration into the sustainability framework has to improve its synchronization with other variables. The study provides new insights into enhancing green market systems in G20 countries to facilitate low-carbon technology exchange for emissions reduction. The findings of this research could be helpful for policymakers to improve green financing strategies, promote digitalization for environmental upgrading, and support effective energy use.

Abstract: Energy & Environment, Ahead of Print.
This paper discusses the uncertainty spillover among climate policy, economic policy, energy market and geopolitics, using time-varying parameter vector autoregression (TVP-VAR) connectedness approach. The major results show that the total connectedness index (TCI) is dominated by long-term connectedness in static analysis. The main spillover transmitters are climate policy uncertainty in China (CPUC) and economic policy uncertainty (EPU) while the receivers are the USA (CPUS) and energy-related uncertainty (ERU) when considering time and frequency. Next, in the dynamic analysis, the TCI exhibits a downward trend, and the net total directional connectedness indicates that CPUC is still a pure transmitter, while CPUS plays a completely opposite role. Finally, dynamic net pairwise analysis shows that CPUC exerts spillovers on EPU, ERU and geopolitical risk. Conversely, CPUS is more likely to accept the shock of other uncertainties. The major contribution is that the different uncertainties are incorporated into a unified research framework, and explain the detailed influencing channels. More importantly, this paper recognizes the different roles of CPUC and CPUS in the entire uncertainty connectedness with considering time and frequency, and argue that China is reshaping global economy, energy market and geopolitical situation. Some policies, including prudent and firm climate policy, international climate cooperation, and depoliticization in climate-related decisions, are provided for promoting economic development, stabilizing energy market and geopolitical tensions.

Abstract: Energy & Environment, Ahead of Print.
Resources and pressure from shareholders or creditors are important influencing factors and opportunities for enterprises to achieve excellence in Environmental, Social and Governance (ESG) value creation. This study constructs multiple networks to characterize the financial relationships among enterprises, shareholders, and creditors, examining their impact and coupling effect on ESG value creation. We find that financial relationship networks are crucial for ESG value creation, with local and global network characteristics affecting ESG outcomes in opposing ways and varying across ESG dimensions. Notably, the ESG value effect of the shareholder network is more significant than that of the creditor network. Increasing interaction between shareholder and creditor relations in multiple networks positively impacts ESG value creation, similar to the effect in a single network. Financing constraints play an indirect role in the relationship, with the value creation impact depending on agency costs. For enterprises with low market competitiveness, the ESG value effect of multiple financial networks is more pronounced than for those with high market competitiveness. This study provides a decision reference for enterprises to build relationship networks with shareholders and creditors and to fulfill the positive ESG governance role of the network.

Abstract: Energy & Environment, Ahead of Print.
The co-pyrolysis process is an essential method for energy extraction from waste biomass and coal although the co-pyrolysis technology of biomass and coal presents a complex engineering challenge. To address these challenges, modern data-driven ensemble and tree-based machine learning approaches offer a promising solution. This study provides a comprehensive analysis of various machine learning techniques, including linear regression (LR), decision tree (DT), random forest (RF), extreme gradient boosting (XGBoost), and adaptive boosting (AdaBoost) to predict the outcome models of pyrolysis oil yield, syngas yield, char yield, and syngas lower heating value from co-pyrolysis of biomass and coal. The models are evaluated using different statistical metrics. The DT-based pyrolysis oil yield model outperformed the other four models (LR, RF, XGBoost, and AdaBoost) in predicting pyrolysis oil with robust accuracy, achieving an R2 of 0.999 and a mean squared error (MSE) close to zero during the model training phase. Similarly, the DT-based syngas yield model showed a high R2 of 0.999 and near-zero MSE while the based char yield model excelled the others with a high R2 of 0.999 and negligible MSE during the model training phase. In the subsequent phase, explainable artificial intelligence-based Shapley additive explanation (SHAP) values were estimated for feature importance analysis. The SHAP analysis identified key features for pyrolysis oil and syngas yield, with biomass blending ratio and reaction time being the most crucial, while reaction time and temperature were the most important for the syngas LHV model.

Abstract: Energy & Environment, Ahead of Print.
To improve energy storage and photocatalytic (PC) activity for the removal of organic pollutants, we synthesize pure and Mn-doped stannic oxide at different concentrations in this work. The physicochemical parameters of the synthesized materials were investigated employing a variety of analytical instruments. Here, we synthesize the samples using a simple hydrothermal approach. At 5 A/g current density, a maximum specific capacitance of 325 F/g was demonstrated by a Mn-doped stannic oxide electrode. After 1000 continuous cycles of charging and discharging, 84.83% retention of capacitance was noted. Additionally, when Mn-doped stannic oxide NPs are utilized as a photocatalyst to reduce brilliant green (BG), alizarin red S (AR S), and methyl orange (MO) dyes in the presence of sunlight, methyl orange shows the highest degradation efficiency of 96% when compared to all other dyes.

Abstract: Energy & Environment, Ahead of Print.
Public interest concerning the environmental progress of economies has been developing across societies and countries. Such awareness requires dealing with energy, environment, and economic sides altogether. By considering this reality, this research investigates that how there is an effect of environmental policy stringency (EPS), energy transition index (ETI), and income (gross domestic product, GDP) on CO2 emissions. In doing so, the research analyzes BRICS countries, which are leading developing countries causing high emissions and consuming large amounts of energy, uses data between 2000/Q1 and 2020/Q4, and uses wavelet local multiple correlation approach to analyzes the nexus across times and frequencies. The results demonstrate that (i) EPS declines CO2 emissions in Brazil at low and high frequencies; (ii) GDP curbs CO2 emissions in India at high frequencies; (iii) across remaining times and frequencies, EPS, ETI, and GDP have a mixed effect in BRICS countries; (iv) based on four-variate cases, EPS, ETI, and GDP have an increasing combined effect on CO2 emissions across all times, frequencies, and countries; (v) the most dominant factor differs according to frequencies and countries, where ETI is mainly leading in Brazil, Russia, and India, EPS is pioneering in South Africa, and China has a mixed situation. Thus, the research empirically proves the diverging effects of EPS, ETI, and GDP on CO2 emissions across times, frequencies, and countries.

Abstract: Energy & Environment, Ahead of Print.
In this study, we evaluated the material and environmental benefits of recycling materials collected at the University of Seoul. The waste composition was analyzed by sampling using the coning and quartering methods at the campus recycling center. The material cost was determined by comparing the prices of raw materials and recycled materials, while the environmental cost was calculated by estimating potential greenhouse gas emissions by incineration and multiplying this by the carbon price. It was analyzed that recycling rather than incineration can reduce greenhouse gas emissions up to 2.8 tCO2eq per tonne of waste. As a result, approximately 250 t of household waste is generated annually at the University of Seoul, with approximately 16% consisting of recyclable materials such as plastic and paper. Based on the carbon price of the Republic of Korea, the potential savings were around 608,000 USD/year. Using the current EU carbon price, the savings increased to 647,000 USD/year, and based on the 2030 target carbon price, the savings amounted to 677,000 USD/year. It represents that recycling not only minimizes natural resource depletion but also mitigates greenhouse gas emissions and results in significant economic cost savings. This research investigates specific methods for calculating monetary values to incentivize recycling and presents practical applications.

Abstract: Energy & Environment, Ahead of Print.
The increasing scarcity of fossil fuels and rising geopolitical and environmental concerns have complicated energy production. Mesua ferrea linn seeds can be used to produce biodiesel as an alternative to conventional food crops. This study examined the catalytic activity of unsupported K2CO3 supported with alumina (K2CO3/Al2O3) in the transesterification reaction. The reaction was optimized using two methods: one variable at a time (OVAT) and Response Surface Methodology (RSM) with a Box-Behnken Design (BBD), which helped identify the linear and interactive effects of process variables on biodiesel yield. OVAT determined the optimal conditions to be: catalyst amount (6 wt%), methanol-to-oil molar ratio (6:1), temperature (60°C), time (60 min), and stirring speed (600 rpm). In contrast, RSM predicted the highest methyl ester conversion with: catalyst amount (6 wt%), methanol-to-oil ratio (7.8:1), temperature (55°C), and time (45 min). A confirmation experiment under RSM conditions achieved a maximum FAME conversion of 95.81%. RSM also indicated that the key parameters influencing transesterification, in order of significance, were temperature, time, and methanol-to-oil ratio. A pseudo-first-order kinetic model was also developed, revealing an activation energy of 53.95 kJ/mol.

Abstract: Energy & Environment, Ahead of Print.
This article investigates the economic and technical feasibility of employing various photovoltaic (PV) tracking systems to electrify Western Pelee Island. The systems under consideration include horizontal-axis monthly adjustment (HMA), horizontal-axis continuous adjustment (HCA), vertical-axis continuous adjustment (VCA), and dual-axis tracker (DAT). The analysis includes a techno-economic assessment of these trackers, considering solar, bio, and diesel operation and two dispatch strategies: cycle charging (CC) and load following (LF). The results indicate that the optimal solution is a CC-controlled system equipped with a VCA tracker. The LF-controlled system with this tracker has a higher net present cost (NPC), cost of energy (COE), and renewable fraction by ∼$0.02 M, ∼$0.002/kWh, and 7.6%, respectively. NPC of HMA and COE of HVA-based systems with CC strategies are the most sensitive cases to SOCmin. In load variation, the largest and lowest decrease in COE, respectively, is observed in HVA and DA trackers controlled by CC dispatch strategy. In order for DA trackers to match the performance of VCA trackers, their costs must decrease by approximately 41% and 43% in CC and LF systems, respectively. The financial sensitivity of DA-based systems is higher due to albedo effects. This study provides valuable insights into optimizing PV tracking for the electrification of Western Pelee Island and enhances our understanding of the economic implications associated with dispatch strategies and tracking technologies in sustainable energy planning.

Abstract: Energy & Environment, Ahead of Print.
Water and energy are key elements to accomplish the Sustainable Development Goals (SDGs) of human society. The aim of this study is to acknowledge and enhance the efficiency of water-energy-related use (WERU) systems from a sustainable perspective. This paper proposes a dynamic parallel-series data envelopment analysis model to assess WERU efficiency towards the targets SDG 6 and SDG 7. The WERU system with parallel-series structure consists of water supply (WS), water use (WU), energy supply (ES), and energy use (EU) subsystems. To investigating the role of digital economy in enhancing WERU efficiency in 30 provinces of China from 2011 to 2020, the intermediary effect model and the spatial Durbin model are applied to explore the transmission mechanism and spatial spillover effect. The main findings are as follows: (1) The average overall efficiency of the WERU system is 0.60, primarily due to the suboptimal performance of the WU and EU subsystems. (2) The central region has lower efficiency scores in the WU and EU subsystems than the eastern and western regions. (3) The digital economy indirectly boosts WERU efficiency by stimulating provincial innovation and industrial structure upgrading. The digital economy is beneficial to enhancing WERU efficiency in local and neighboring provinces. This study advocates for the sustainable advancement of the WERU system by encouraging provincial innovation, upgrading industrial structures, and underscoring the growth of the digital economy.

Abstract: Energy & Environment, Ahead of Print.
This research examines the strategic development and progress of green energy initiatives on offshore islands under the auspices of the Chinese government. The primary methodologies employed are the Decision Making Trial and Evaluation Laboratory and the analytic network process, in conjunction with the VIKOR method. The analysis focuses on four primary dimensions: benefits, opportunities, costs, risks, and their respective subdimensions. Results indicate the need to consider risk first, followed by cost, benefit, and opportunity. They also underscore the importance of the government focusing on risk management and cost-effectiveness when implementing green energy infrastructure. Subsequently, the potential benefits and opportunities should be evaluated to enhance the effectiveness of green energy systems in Taiwan's offshore islands and ensure optimal operational efficiency.

Abstract: Energy & Environment, Ahead of Print.
Improving material productivity (MP) and energy intensity (EI) is a crucial tool for sustainable consumption and production targets of SDGs. However, the diverse effects of climate-related development finance (CDF), digital infrastructure (DI), and financial development (FD) on MP and EI in developing countries (DCs) remain underexplored. Therefore, employing the method of moments quantile regression (MMQR) approach, this study examines the heterogeneous effects of CDF, DI, and FD on MP and EI across 87 DCs from 2000 to 2020. Also, the effects of CDF and DI on MP and EI are explored, considering the FD heterogeneity. The results imply that CDF, FD, and DI have beneficial effects on MP and energy efficiency (EE). Specifically, DCs with the higher distribution of MP benefit more from CDF and FD, with CDF coefficients rising from 0.004 to 0.019 across quantiles and FD estimates increasing from 0.224 to 0.391 from medium to the higher quantile. Conversely, DCs with lower EI benefit more from CDF and FD, as indicated by the coefficients of CDF and FD, ranging from −0.017 to −0.012 from 20th to 80th quantile and −0.569 to −0.233 from 40th to 60th quantile, respectively. Besides, DCs with higher distribution of MP and EI drive more gain from DI improvement. Besides, the effects of CDF and DI are influenced by variations in FD. These findings have vital implications for developing prudent financial and digitalization policies to promote MP and EE in DCs, congruent with SDG-7.3, SDG-8.4, and SDG-12.2 for improving energy and resource efficiency and management.

Abstract: Energy & Environment, Ahead of Print.
The present study investigated the synthesis of sodium alginate encapsulated magnetic graphene oxide (SAMGO) beads from Strychnous Potatorum seeds. The synthesized SAMGO beads were investigated for adsorptive removal of nickel from aqueous solution. The synthesized SAMGO beads were characterized for surface morphology, functional groups, magnetic property and phase identification using SEM, FT-IR, VSM and XRD analysis. The optimization process involving the SAMGO beads for adsorptive removal of nickel resulted in maximum removal rate under the conditions of contact time – 15 min, SAMGO bead dose – 10 mg/50 mL of solution, nickel ion concentration – 50 mg/L, pH-9 and temperature of 30 °C. Adsorption of nickel onto SAMGO beads was well studied by pseudo-second-order kinetic studies. Also, the adsorption equilibrium study was well fitted towards Freundlich isotherm (R2 = 0.99). The findings from the regeneration studies demonstrated that the selected desorbing agents, 0.5 M HCl and 0.5 M EDTA were well-suited for desorption. After five experimental cycles, the desorption efficiency decreased by only 10.93% and 7.76% using 0.5 M HCl and 0.5 M EDTA, respectively indicating that the SAMGO beads for reusability. The synthesized SAMGO beads have shown potential to reuse, nontoxic green adsorbent with maximum removal rate.

Abstract: Energy & Environment, Ahead of Print.
Many researchers have documented the effects of deploying natural resources on gross domestic product (GDP) growth and confirmed the existence of the resource curse phenomenon. Furthermore, several studies have proved that factors such as institutional quality, trade openness, and commodity price volatility can alter the effects of natural resource deployment on economic growth. However, few studies have considered the effect of green transition on the resource curse. While transitioning to a green economy poses the threat of reducing the potential revenues from exporting natural resources in resource-abundant economies, it can contribute to economic growth by reducing fossil fuel dependance, increasing energy efficiency, and increasing green competitiveness. In this study, we analyze how fossil fuel rents affect GDP growth and study the interactive effects of renewable energy and investment in green research and development. By using the data of 109 countries for the period 1990–2020, we conduct a panel analysis. The results confirm the existence of the resource curse effect, whereby fossil fuel rents hinder economic growth. In addition, increasing renewable energy deployment can alleviate the adverse effects of fossil fuel rents. This mitigation can occur through a reduction in the domestic consumption of fossil fuels, increased access to international trade, and infrastructure investments. Lastly, increasing investments in green research and development mitigates the adverse effects of fossil fuel deployment. This result is achieved because of increases in energy efficiency, investment in human capital, and green competitiveness. We conclude that active green transitioning, especially in fossil-fuel-rich economies, can lead countries to sustainable growth.

Abstract: Energy & Environment, Ahead of Print.
This study examines the two-way asymmetric energy-economic growth relationship using novel second-generation nonstationary panel approaches, namely nonlinear dynamic common correlated effects (nonlinear DCCE), cross-sectionally augmented nonlinear autoregressive distributed lag (CS-NARDL) and cross-sectionally augmented nonlinear distributed lag (CS-NDL) approaches. These models cover long panel data estimation issues of nonstationarity, heterogeneous slopes and cross-sectional dependence. However, their standard models are linear approaches and neglect asymmetric effects. Besides, economic variables might vary over time and react heterogeneously to shocks. Hence, this study fills this gap by innovating the linear models into nonlinear models to explore asymmetric relationships. The results’ robustness is checked with baseline models. This study compares the nexus in two contrasting income groups, that is, lower-income and high-income economies, from 1990 to 2019. Overall, energy consumption and gross domestic product (GDP) are positively linked in the long-run bidirectional nexus for both groups. Nevertheless, energy consumption has a weaker influence on the lower-income nations’ GDP, signifying lower energy efficiency. The favourable short-run impact of energy consumption decreases on lower-income countries’ GDP is noticeable, highlighting the importance of energy conservation. The reverse linkage's result, which reveals higher GDP accelerates energy consumption in both groups, reinforces energy conservation and the energy transition to renewables to ensure energy security. The upsurge in energy consumption due to the increased GDP is larger in lower-income economies, suggesting room for improvement in energy technologies. Furthermore, energy consumption and GDP are affected by their delayed effects. Therefore, authorities should always be alert to historical trends and potential business cycle fluctuations.

Abstract: Energy & Environment, Ahead of Print.
This study investigates the trade-off between green energy transition (GET) and energy security (ES) for eliminating energy poverty (EP) and the role of fintech development in 112 Belt and Road Initiative (BRI) countries from 2000 to 2022. To our knowledge, this is the first empirical study analyzing this nexus for BRI countries. BRI country's reliance on conventional non-renewable energy resources due to EP and modern energy inaccessibility is a question mark. Therefore, it is crucial to analyze whether ES assurance as a production-to-consumption ratio or transitioning to modern energy as green transition could benefit EP alleviation. Moreover, the role of fintech development is to strengthen the relationship between GET, ES, and EP eradication. Considering these important but ignored aspects in existing literature, the present study focused on filling this gap. Estimates from panel quantiles indicate that GET and ES both are significant for EP alleviation but the magnitude of GET is higher in comparison with ES. After applying robust estimates, the conclusion remains the same. Our study further examined the moderating role of fintech development between GET, ES, and EP. Findings confirmed that fintech development is a strong moderator between selected variables. Based on these findings, our study suggests that transitioning to green energy is optimal for EP reduction rather than focusing energy production on consumption patterns. This study further recommends improving fintech services because it strengthens the relationship between GET and EP alleviation.

Abstract: Energy & Environment, Ahead of Print.
Organic phase change materials (PCMs) have gained huge importance for thermal energy storage systems, but their applicability is restricted due to their low thermal conductivity and hardness. The aim of this research work is to solve the problem by developing a novel organic binary eutectic PCM employing paraffin wax and coconut oil in the eutectic mixture (ratio 1:1) to soften the PCM for thermal comfort applications. 3D expanded graphite (EG) was used as a filler to enhance the thermophysical properties of eutectic-EG PCM composite formed by melt-mixing technique. The percolation limit of EG was 0.5 wt-% to form the thermal network in PCM matrix. The thermal conductivity of eutectic-EG PCM composite enhanced significantly from 0.2 W m−1 K−1 to 0.55 W m−1 K−1 at 2 wt-% of EG in pristine PCM. Differential scanning calorimetry (DSC) was carried out to analyse the energy storage enthalpies and temperatures of composites. The 50 consecutive thermal heating and cooling cycles performed by conventional heating system showed the good thermal reliability of the composite. The numerical 2D simulation was conducted to reveal the heat propagation behaviour in the developed composite with the post-EG addition and to validate the enhanced thermal conductivity results obtained experimentally. The cost analysis results reveals that the cost per mean power of the composite is composite is approximately 100% lower than the pristine PCM. The developed composite's outstanding energy storage property indicates its potential for developing the soft heating pads/cartridges for human comfort and also the solar thermal energy storage applications for medium temperature ranges.

Abstract: Energy & Environment, Ahead of Print.
The role of industrial sectors, including construction (CONS) and manufacturing (MFG), in mitigating carbon dioxide (CO2) emissions is often overlooked. The response of these indicators in environmental sustainability is gaining critical attention among scholars and policymakers. Therefore, this research aims to address this issue by investigating the impact of nonrenewable energy consumption (NREC) under the moderating effects of CONS and MFG on Canada's CO2 emissions from 1980 to 2021, utilizing both traditional autoregressive distributed lags (ARDLs) and dynamic ARDL simulation methods. The findings reveal that NREC, CONS, and economic growth (GDP) are significant drivers of emissions in both the short and long run. Meanwhile, MFG reduces emissions in the long run with no significant short-run impact. Further analysis using Generalized Kernel-based regularized least squares (gKRLS) and frequency domain causality (FDC) tests confirmed these results. Moreover, examining the moderating role of CONS and MFG exhibits significant long-run positive moderating effects on the NREC-CO2 relationship, with MFG having a more substantial impact than CONS. However, both sectors show insignificant adverse moderating effects in the short run. Robustness analysis using quantile regression (QREG) and simultaneous quantile regression (SQREG) demonstrates that GDP and MFG consistently mitigate CO2 emissions across all quantiles, with stronger effects at higher emissions levels. These results underscore the importance of targeted renewable energy policies that balance economic growth with environmental sustainability.

Abstract: Energy & Environment, Ahead of Print.
Growing concerns over food shortages and climate-related environmental issues have increased interest in technologies that recycle renewable resources and add value to byproducts. Here, we report microbial upcycling of agricultural cabbage waste (ACW) into phytoene, a novel dietary carotenoid through rational metabolic engineering. To make the base strain, the ability to produce phytoene was initially tested in various E. coli strains harboring the crtB and crtE genes that are essential for phytoene synthesis. Next, the mevalonate biosynthetic pathway gene cluster was introduced to further increase carbon flux toward phytoene production. Finally, the gene cluster for poly(3-hydroxybutyrate) [P3HB] biosynthesis was further introduced into the phytoene-producing strain to increase phytoene storage capacity and enhance photostability of phytoene. The final engineered strain PHY4 produced 9.51 mg/L (5.6 mg/g DCW) of phytoene, with a productivity of 0.4 mg/L/h from 1% ACW hydrolysates, resulting in approximately a 22.1-fold increase in phytoene titer compared to the base strain PHY1 (0.43 ± 0.06 mg/L) from 10 g/L of glucose. Moreover, the PHY4 strain exhibited a three-fold improvement in photostability for phytoene. The strategies reported here will be useful for the microbial upcycling of various waste resources into high-valued natural products.

Abstract: Energy & Environment, Ahead of Print.
In this study, a three-dimensional computational fluid dynamics (CFD) model using multiphase particle-in-cell (MP-PIC) method with large eddy simulation (LES) was developed to investigate the characteristics of the co-gasification of densified wood pellets (WP) and rice husk pellets (RHP) with SRF in a bubbling fluidized bed reactor. ER reduction from 0.30 to 0.10 resulted in a decrease in specific gas yield per total feed from 1.20 g/gtotal to 0.96 g/gtotal and from 1.20 g/gtotal to 0.67 g/gtotal during SRF/WP and SRF/RHP co-gasification, respectively. Reducing ER during SRF/WP co-gasification allows to increase C2–C3 HCs yield reaching 0.33 g/gsrf (0.15 g/gtotal) at ER = 0.15, 0.556 kg/h SRF, and 0.693 kg/h WP. Carbon conversion efficiency (CCE) and cold gas efficiency (CGE) at the same conditions reduced to 83% and 74%, respectively. Co-gasification of 0.667 kg/h SRF and 2.040 kg/h RHP allowed to reach 0.28 g/gsrf (0.07 g/gtotal) C2–C3 HCs yield, but drastically reducing CCE and CGE to 71% and 46%, respectively. SRF/WP co-gasification is suggested for low cost C2–C3 HCs recovery from SRF with coproduction of syngas retaining 48% to 57% of initial LHV, meaning that SRF/RHP co-gasification is more suitable for syngas production.

Abstract: Energy & Environment, Ahead of Print.
Financial development serves as a key indicator to achieve rapid economic growth and environmental sustainability globally. Therefore, this study explores how financial development, economic globalization, and green energy influence carbon emissions, along with GDP, technological innovation, and trade openness, in the Next-11 emerging economies from 1990 to 2022. The cointegration and causality associations are analyzed by using the Panel Common Correlated Effect Mean Group (CCEMG) and Augmented Mean Group (AMG) techniques to achieve our objective. The empirical results from the AMG analysis indicate that financial development, technological innovation, and green energy contribute to diminishing CO2 emissions by 1.25%, 2.23%, and 2.90%, respectively. Conversely, economic globalization, trade liberalization, and economic growth have negative impacts on the environment, increasing emissions by 1.04%, 0.13%, and 0.18%, respectively. Similarly, findings from the CCEMG outcomes expose the inverse link between financial expansion and environmental degradation. Our outcomes highlight that policymakers should prioritize sustainable practices for the development of financial markets, particularly for businesses that invest in cleaner technologies and renewable energy. This integrated strategy is necessary for the Next-11 emerging countries to accomplish their SD goals and effectively confront climate change.

Abstract: Energy & Environment, Ahead of Print.
Countries take measures to protect the environment as compatible with the increasing interest in climate change-related issues. In this context, this research analyzes the impact of environmental policy stringency (EPS), energy transition index (ETI), and income (GDP) on environmental quality. In doing this, the study examines BRICS countries, which are the leading developing countries that cause higher emissions, consume higher amounts of energy, and have higher economic growth, uses data from 2000/Q1 to 2020/Q4, and performs wavelet local multiple correlation (WLMC) model to investigate the relationship under time and frequency-based diverging scheme. In bivariate cases, EPS, ETI, and GDP have a differentiating impact on load capacity factor (LCF) across countries, where there are some exclusions. These factors have a generally increasing impact on LCF. In contrast, EPS has a decreasing impact at low (medium) frequency in Russia (South Africa), ETI has a declining impact at high frequency in Brazil and China, GDP has a decreasing impact at lower frequency in Russia, medium and high frequency in China, and higher frequency Brazil and South Africa. In four-variate cases, the factors have a fully increasing impact on LCF in the countries for all times and frequencies, while the impact is stronger at higher frequencies. GDP is the dominant factor in India and China, while ETI (EPS) is leading in Brazil and Russia (South Africa). Thus, the study reveals the dynamic impacts of EPS, ETI, and GDP on LCF, which diverge across times, frequencies, and countries. Accordingly, policy options for BRICS are argued.

Abstract: Energy & Environment, Ahead of Print.
The global economic landscapes are overshadowed by monetary policy uncertainty (MPU), challenging various sectors. However, its impact on renewable energy consumption (REC) remains ambiguous, reflecting the sector's complex interplay with economic forces. This study seeks to unravel the complexities by examining how fluctuations in monetary policy affect REC in key emerging economies, including China, India, Russia, Brazil, South Africa, Indonesia, Mexico, Turkey, Nigeria, and Vietnam. Previous studies predominantly relied on panel data techniques, overlooking the distinct traits of individual nations. In contrast, this investigation employs the refined Quantile-on-Quantile approach to meticulously analyze the relationship between variables in each economy separately, thus enhancing precision. By integrating this advanced method, the study uncovers previously unnoticed dynamics across emerging economies, offering a more nuanced and accurate assessment than traditional methods. This approach provides a holistic global perspective and tailors insights to specific economies, addressing the complexity of MPU's impact on REC. The findings reveal that MPU negatively affects REC across various quantiles in most selected nations, an insight with significant practical implications. These results offer invaluable guidance for policymakers in developing strategies to mitigate the adverse effects of monetary uncertainty, enabling the design of targeted, nation-specific policies for promoting sustainable energy use.

Abstract: Energy & Environment, Ahead of Print.
Carbon emission efficiency (CEE) reflects the interplay between carbon emissions and the economy, which refers to achieving more economic benefits and lower carbon emissions while considering energy, labor, and capital inputs. Assessing regional CEE is crucial for evaluating the level of China's regional low-carbon economic development. Thus, this paper proposes a scenario-based hybrid model with a foresight perspective and game cross-efficiency (GCE) analysis. It measures the future CEE of 41 Yangtze River Delta (YRD) cities from 2023 to 2030. The improved gray forecasting models generate the input and output datasets for GCE analysis, and the assurance region constraint simulates the carbon emission and energy consumption dual-control policy. The results show that: (1) the CEEs of 41 cities are generally low, with an average of 0.2142. Shanghai has the highest CEE, 0.8089, while Tongling has the lowest, 0.0307, under the current policy constraint. (2) Under the four control policy scenarios, the CEE of the YRD urban agglomeration generally follows a U-shaped trend. It indicates that the dual-control policy may lead to a short-term decline in the CEE of YRD, but in the long term, it may gradually increase in 2025 or 2026. (3) Spatial–temporal analysis reveals that the government should flexibly optimize and update the carbon intensity constraint value based on regional development differences and focus more on energy consumption. These results provide forward-looking guidance for China's regional low-carbon and high-quality development.

Abstract: Energy & Environment, Ahead of Print.
In the industry, the discussion of energy and exergy analysis has gained increasing importance due to human needs from the past to the present. In the textile industry, this analysis has only been implemented in a limited manner and in isolated units. Specifically, in the dyeing, printing, and finishing units, steam and hot oil energy is utilized for heating processes. This heating requirement is met by steam boilers and hot oil boilers, which are essential for the operation of an integrated system. Identifying factors of energy loss and pollutant production, along with applying energy improvement techniques in textile factories, can significantly reduce the problems associated with fossil fuels. To identify potential energy and environmental improvements, an energy audit was conducted throughout the Borujerd Textile Factory in Iran, which goes beyond previous fragmented and isolated assessments to provide a comprehensive review of the entire system. This audit integrated thermography and flue gas analysis to enhance the accuracy and effectiveness of performance evaluation. By performing exergy, exergoeconomic, and exergoenvironmental (4E) analyses, the performance of the existing system was evaluated, providing a comprehensive overview of efficiency and the potential for improvements and optimizations. Environmental impact analysis was conducted using life cycle assessment in SimaPro for different sections of the plant. The results indicate that the most significant exergy destruction occurs in steam boilers and hot oil boilers, totaling 33.5 MW and 91%, respectively, as well as the washing after printing machine in the dyeing department, accounting for 3% of total exergy destruction due to high energy wastage and low efficiency in these devices. The cost rate of overall exergy destruction is estimated at $61.1 per hour. The highest environmental impacts were observed for steam boilers and the pad steam machine in the dyeing department, primarily due to the equipment's structure and the use of polluting materials that contribute to emissions from these devices. After the energy audit, the most effective solutions to the identified problems were proposed. It was also determined that the most significant heat loss occurs in pad steam machines, washing after printing, and bleaching washing machines.

Abstract: Energy & Environment, Ahead of Print.
The development of the internet is of great significance for carbon reduction in the transportation sector. Drawing on panel data from 31 provinces in China spanning 2011 to 2021, we present novel evidence from the transportation sector. We construct an internet development assessment system comprising 18 indicators and compute an internet development index from four dimensions. Employing OLS, mediation analysis, and dynamic threshold panel models, we validate the relationship between the internet development index and carbon emissions in the transportation sector. Results indicate a significant increase in transportation sector carbon emissions with internet development, with a 0.072% rise in emissions for every 1% increase in the internet development index. This is primarily attributed to the influence of internet development on increasing internet shopping, vehicle ownership, and travel scale. Importantly, in regions with higher transportation sector carbon emissions, such as Shanghai, internet development may also lead to emission reductions. Thus, the Chinese government should pay particular attention to strategically employing internet technology in different regions, leveraging its technical advantages to promote carbon emission reduction strategies in the transportation sector.

Abstract: Energy & Environment, Ahead of Print.
China is one of the world's largest producers of mineral resources and possesses abundant mineral reserves, and its mining industry thus plays a crucial role in the country's economic development. However, most studies overlook the importance of geological exploration activities preceding mineral production and the impact of land restoration on said production under external environmental factors. Therefore, this research utilizes the meta recycle undesirable dynamic three-stage directional distance function (DDF) under exogenous model to investigate geological exploration stage efficiency, mineral production stage efficiency, and land restoration stage efficiency in different regions of China. The research findings are as follows. (a) The overall efficiency in the east region surpasses that of the other regions. (b) The central region exhibits the lowest efficiency in the geological exploration stage and mineral production stage. (c) Land restoration stage efficiency in all regions needs improvement due to the impact of precipitation.

Abstract: Energy & Environment, Ahead of Print.
Biodiesel is considered to be an economical and eco-friendly substitute to fossil fuels. The present research was focused on the synthesis of potassium doped biochar catalyst from wood dust waste. The synthesized activated biochar catalyst was subjected to characterization using various techniques such as FT-IR, SEM-EDAX, XRD analysis which showed possible higher catalytic efficiency. The microalgae Chlorella vulgaris oil was used for the biodiesel production through transesterification reaction using the synthesized potassium doped biochar catalyst. The reaction parameters were optimized using statistical methods and the optimized conditions were found to be of 5.46% of catalyst dosage, 10.39:1 of methanol to algal oil ratio, 61.41 °C of temperature and 75.3 min of time with the highest biodiesel yield of 91.9%. The reaction kinetics was studied and it was found to follow the first-order kinetics with an activation energy of 12.18 KJ/mol. The catalyst reusability study exhibited higher catalytic performance until fourth cycle. Overall, the utilization of microalgae as a biofuel source and industrial waste as a catalyst contributes to sustainable biodiesel production and promotes a greener environment by reducing dependency on fossil fuels and minimizing industrial waste.

Abstract: Energy & Environment, Ahead of Print.
This research takes the pollution information transparency index as a quasi-natural experiment, and empirically tests the impacts of the environmental information disclosure（EID） policy on carbon intensity and carbon productivity at the city level by using the difference-in-differences(DID) model and its derivative models, using the pilot policy of urban pollution source regulatory information disclosure. The findings are as follows: Firstly, EID has a prominent inhibition effect on carbon intensity and a significant improvement effect on carbon productivity, which is still robust under multiple scenarios. Secondly, considering the possible differential effects of EID on carbon intensity and carbon productivity between the pilot and non-pilot cities, the spatial double-difference approach is constructed to further analyze the local effect and spillover effect. The result indicates that EID has a direct inhibition effect on carbon intensity in local pilot cities and a spatial negative spillover effect on it in non-pilot cities. Thirdly, heterogeneity analysis demonstrates that the effect of EID is more significant in the eastern and central cities, large and medium cities, and non-resource cities. Thus, this paper puts forward the policy recommendations including gradually increasing the number and improving the content of pilot cities to enhance the spatial spillover effect, building a cross-level environmental collaborative governance mechanism to achieve diverse participation, leadership and demonstration, encouraging positive interaction of urban environmental governance at different levels, and making further classification guidance and policies to promote carbon reduction and quality enhancement.
