Reinvigorating the role of clean energy transition for achieving a low-carbon economy: evidence from Bangladesh

Analyzing the effectiveness of energy aid for driving the transition towards energy decarbonization; Evidence from Asian developing countries

Environmental degradation poses a significant challenge in many developing countries, as they heavily rely on fossil fuels to drive economic activities. The transition towards renewable energy is crucial to mitigate ecological depletion, yet numerous Asian developing countries may struggle to achieve the desired levels of renewable energy adoption due to financial constraints. Foreign aid in the energy sector can expedite this transition process. This study aims to examine the impact of foreign aid on the energy decarbonization transition in 22 Asian developing countries from 2003 to 2022 to analyze its contributions and challenges to promote renewable energy adoption. This paper incorporates the two types of foreign aid in the energy sector (nonrenewable and renewable energy aid) provided by the OECD to developing economies. Utilizing the System-Generalized Method of Moments (Sys-GMM), the findings reveal that energy aid significantly contributes to the transition towards energy decarbonization by providing financial support for embracing renewable energy technologies. Specifically, the analysis indicates that a 1% increase in energy aid leads to approximately 3% enhancement in the decarbonization transition process. Moreover, this study adds to the existing body of knowledge by examining the mediating impact of human capital and financial development as well as the moderating effect of institutional quality and demand for clean fuel. These factors play a pivotal role in energy decarbonization transition by fostering financial development and enhancing human capital through capacity-building initiatives and facilitating the adoption of renewable energy technologies.

Role of energy transition in easing energy security risk and decreasing CO2 emissions: Disaggregated level evidence from the USA by quantile-based models

Consistent with the increasing environmental interest, the clean energy transition is highly critical to achieving decarbonization targets. Also, energy security has become an important topic under the shadow of the energy crisis,. Accordingly, countries have been trying to stimulate clean energy use to preserve the environment and ensure energy security. So, considering the leading role of economic size and volume of energy use, the study examines the USA to define whether energy transition helps decrease energy security risk (ESR) and curb CO2 emissions. So, the study applies a disaggregated level analysis by performing quantile-based models for the period from 2001/Q1 through 2022/Q4. The results demonstrate that (i) the energy transition index decreases environmental ESR at higher quantiles and reliability ESR at lower and middle quantiles, whereas it is not beneficial in declining economic and geopolitical ESR; (ii) energy transition curbs CO2 emissions in building and transport sectors at lower quantiles, whereas it does not help decrease CO2 emissions in industrial and power sectors; (iii) energy transition is mostly ineffective on ESR, whereas it is highly effective in curbing CO2 emissions in all sectors except for transport across various quantiles as time passes; (iv) the results differ according to the aggregated and disaggregated levels; (v) the results are consistent across main and alternative models. Hence, the study highlights the dominant effect of energy transition in curbing sectoral CO2 emissions rather than easing ESR. Accordingly, the study discusses various policy implications for the USA.

Unleashing the Power of Sn2 S3 Quantum Dots: Advancing Ultrafast and Ultrastable Sodium/Potassium-Ion Batteries with N, S Co-Doped Carbon Fiber Network

Tin sulfide (Sn2 S3 ) has been recognized as a potential anode material for sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) due to its high theoretical capacities. However, the sluggish ion diffusion kinetics, low conductivity, and severe volume changes during cycling have limited its practical application. In this study, Sn2 S3 quantum dots (QDs) (≈1.6 nm) homogeneously embedded in an N, S co-doped carbon fiber network (Sn2 S3 -CFN) are successfully fabricated by sequential freeze-drying, carbonization, and sulfidation strategies. As anode materials, the Sn2 S3 -CFN delivers high reversible capacities and excellent rate capability (300.0 mAh g-1 at 10 A g-1 and 250.0 mAh g-1 at 20 A g-1 for SIBs; 165.3 mAh g-1 at 5 A g-1 and 100.0 mAh g-1 at 10 A g-1 for PIBs) and superior long-life cycling capability (279.6 mAh g-1 after 10 000 cycles at 5 A g-1 for SIBs; 166.3 mAh g-1 after 5 000 cycles at 2 A g-1 for PIBs). According to experimental analysis and theoretical calculations, the exceptional performance of the Sn2 S3 -CFN composite can be attributed to the synergistic effect of the conductive carbon fiber network and the Sn2 S3 quantum dots, which contribute to the structural stability, reversible electrochemical reactions, and superior electron transportation and ions diffusion.

An empirical examination of the environmental sustainability-influencing mechanisms of renewable energy: contextual evidence from Next Eleven countries

Recognizing the environmental development-related commitments made by the Next Eleven countries at 26th Conference of Parties (COP26), this study scrutinizes the repercussions accompanying good democratic governance, renewable energy transition, economic growth, and the ratification of the Kyoto Protocol on carbon emission figures of these emerging nations. In this regard, the period of analysis considered spans from 1990 to 2018 while the econometric analyses involve application of both parametric and non-parametric panel data estimators. Among the key findings, firstly, the outcomes from the parametric estimation methods verify that establishing better democratic governance and undergoing renewable energy transition, both independently and jointly, curb carbon emission levels, while higher economic growth and the signing of the Kyoto Protocol are responsible for boosting emissions the Next Eleven countries. Secondly, the findings derived using the non-parametric methods reveal a great deal of heterogeneity when compared with the results obtained from the parametric analysis. Notably, better democratic governance is seen to reduce carbon emissions in less and moderately polluted. Next Eleven nations, while renewable energy transition curbs emissions only in the moderately and highly polluted ones. Additionally, these variables jointly inhibit emissions only in the Next Eleven nations that are moderately polluted. Besides, better democratic governance is observed to mediate the renewable energy transition-carbon emissions nexus only for the less-polluted Next Eleven nations, while the environmental impacts of economic growth and the signing of the Kyoto Protocol vary across different emission quantiles. Accordingly, relevant policies are recommended for helping the Next Eleven countries to comply with their pledges made at the COP26.

Understanding the Role of Technology in Asian Economies: The Environmental Impact of Remittances and Economic Complexity

In recent years, scholars have determined various determinants of environmental degradation using the panel and time-series studies. However, technological innovations (TI) and remittances, among the financial system's essential components, are relatively ignored. In addition, nations' economic progress and environmental performance also depend upon the nature of their economic structure. This empirical research investigates the effects of TI, remittances and economic complexity (EC) on CO2 controlling economic growth and trade openness (TR) in the selected 15 Asian nations. The study collected panel data of 15 Asian countries from 1990 to 2019 and employed the panel quantile regression and augmented mean group methods to unveil the impacts of variables on CO2 emissions. The empirical findings established that remittances are negatively linked with CO2 emissions. Similarly, EC reduces CO2 emissions in the context of Asian countries. In addition, EC and remittances Granger cause CO2 emissions. These findings indicate that remittances and EC positively contribute to environmental quality in Asian countries. Conversely, TI, economic growth, and TR intensify CO2 emissions in Asian countries. Finally, the study recommended policies to enhance remittances and EC in Asian countries to curb environmental degradation.

Morphological and Coordination Modulations in Iridium Electrocatalyst for Robust and Stable Acidic OER Catalysis

Proton exchange membrane water splitting (PEMWS) technology has high-level current density, high operating pressure, small electrolyzer-size, integrity, flexibility, and has good adaptability to the volatility of wind power and photovoltaics, but the development of both active and high stability of the anode electrocatalyst in acidic environment is still a huge challenge, which seriously hinders the promotion and application of PEMWS. In recent years, researchers have made tremendous attempts in the development of high-quality active anode electrocatalyst, and we summarize some of the research progress made by our group in the design and synthesis of PEMWS anode electrocatalysts with different nanostructures, and makes full use of electrocatalytic activity points to increase the inherent activity of Iridium (Ir) sites, and provides optimization strategies for the long-term non-decay of catalysts under high anode potential in acidic environments. At this stage, these research advances are expected to facilitate the research and technological progress of PEMWS, and providing some research ideas and references for future research on efficient and inexpensive PEMWS anode electrocatalysts.

Revisiting the impact of trade openness on environmental sustainability in Belt and Road countries: a heterogeneous panel approach

The nations participating in the Belt and Road Initiative (BRI) are particularly vulnerable to the challenges posed by climate change due to their extensive trading activities. The need to protect the environment and mitigate the adverse impacts of climate change in these countries is of utmost importance. Therefore, this study contributes to the scientific understanding of this issue by examining the relationship between trade openness and environmental sustainability in 89 BRI countries from 1990 to 2020. Additionally, control variables, including economic growth, energy consumption, urbanization, industrialization, and foreign direct investment, are considered to address omitted variable bias issues. The study utilizes the Augmented Mean Group (AMG) and Common Correlated Effects Mean Group (CCEMG) regression estimators, and the findings reveal that trade openness improves environmental sustainability. However, economic growth, energy consumption, urbanization, and industrialization degrade environmental sustainability. Interestingly, the results affirm foreign direct investment as a trivial determinant of environmental sustainability. Regarding causal relationships, reciprocal causalities are observed between trade openness and carbon emissions, energy consumption and carbon emissions, and urbanization and carbon emissions. Furthermore, one-way causalities exist from economic growth to carbon emissions and from carbon emissions to foreign direct investment. Nevertheless, no causal relationship is identified between industrialization and carbon emissions. Based on these significant findings, it is recommended that China, as a prominent player in the BRI, takes further steps to enhance and promote energy-efficient practices in BRI countries. One practical approach is the establishment of energy efficiency standards for the goods and services traded with these countries.

Toward China's green growth through boosting energy transition: the role of energy efficiency

The primary purpose of this study is to quantitatively evaluate whether low-carbon energy transition has achieved preliminary progress in facilitating China's green evolution of economy following the provincial dataset. Besides, how improved energy efficiency moderates the influence of energy transition on green growth and the mediation effects are also quantitatively explored. The primary findings insist that low carbonization energy transition is positively associated with green growth, a finding detected by a series of sensitivity checks. Besides, the reciprocal actions between adjusting energy structure and raising energy productivity can effectively strengthen their roles in promoting green growth. In addition, boosting clean energy transition plays an indirect role in green growth by enhancing energy productivity while directly facilitating green growth. Following the three outcomes, this study puts forward some policy implications on enhancing governmental supervision, promoting clean energy evolution, and upgrading ecological protection technologies.

Role of environmentally related technologies and revenue taxes in environmental degradation in OECD countries

The purpose of this study is to validate the impact of foreign direct investment inflows (FDI inflows), trade openness (TO), environmentally related technologies (ERTs), environmentally related tax revenues (ERTRs), and economic growth (EG) on carbon dioxide (CO₂) emissions by employing a PMG (pooled mean group) estimator with a dataset of 36 OECD countries spanning from 1990 to 2020. Im-Pesaran-Shin, Fisher-type, and cross-sectional augmented Dicky-Fuller tests indicate that study variables are stationary at I (0) and I (I). Kao and Pedroni cointegration test results show that cointegration exists across regressors and regressands throughout the sample of OECD countries. The results of the Hausman test confirm that the PMG panel ARDL method can be employed. Empirical results of PMG demonstrate that ERTRs help to reduce CO₂ emissions, while FDI inflows, TO, ERTs, and EG are significant and positively related to environmental degradation. This study is an effort to fill the gap by exploring the role of ERTs and ERTRs in environmental degradation in selected OECD countries. The study findings support the relationship between CO₂ emissions, ERTs, and ERTRs. It has been determined that environmental technologies and revenue taxes are also drivers of environmental sustainability. The study provides policymakers with pertinent implications for promoting the development and adoption of green technologies. The findings suggest that imposing environmental taxes expedites the development of environmentally related technologies for reducing CO₂ emissions and promoting sustainable development in OECD countries, with potential applications in a wide range of countries, particularly as a basis for emerging countries to boost their energy transition timelines.

Exploring the interrelationship among health status, CO2 emissions, and energy use in the top 20 highest emitting economies: based on the CS-DL and CS-ARDL approaches

Carbon dioxide emissions (CO2e) which is caused by energy use contributes to the global average surface temperature increase by 1.5 °C as compared to the mid-1800s which is causing a certain change in the climate and becoming an adverse effect on health and economy. The relationship between health status, CO2e, and energy use has yet to be thoroughly investigated in the top 20 highest emitting economies. The data from 2000 to 2019 is analyzed by using advanced techniques of cross-sectional augmented distributed lag (CS-DL) and cross-sectional augmented autoregressive distributed lag (CS-ARDL) which take into consideration crucial elements of panel data, namely dynamics, heterogeneity, and cross-sectional dependence. Moreover, cross-sectional augmented error correction method (CS-ECM) and the common dynamic process of the augmented mean group (AMG) are applied for robustness checks. The empirical findings revealed that (i) CO2e weakens the health status only in the short-run, whereas health expenditure improves the health status in the both short- and long-runs, while economic growth is not contributing to the health status in the both short- and long-runs; (ii) health expenditure and economic growth only help to mitigate CO2e in the long-run, whereas energy use causes CO2e in the both short- and long-runs; (iii) energy use causes high economic growth in the both short- and long-runs, whereas CO2e aids economic growth in the short-run but is extremely damaging to economic growth in the long-run, while in the both short- and long-runs health expenditure is not aiding the economic growth. This study provides policy recommendations on improving human health by advocating massive health expenditures, CO2e easing, promoting renewable energy use or low-emission energy, and steering the economy toward green economic growth.

Does governance play any role in energy transition? Novel evidence from BRICS economies

Indubitably, energy transition, which is responsible for enhancing renewables in the energy mix, is considered one of the finest strategies for reducing non-renewable utilization and thus helping economies achieve sustainable development goals (SDGs). In this regard, technological innovation and good governance are not only helpful in stimulating green energy supply but also enhance the efficiency of resources to reach the goals. Along with it, diligent long-term policies are required to inculcate some progression in the achievement of SDGs for climate safety. Thereby, factors such as good governance, technological innovation, trade openness, and economic growth can be addressed in a single framework. To achieve the objective of the study, we employ second-generation panel estimation techniques that are robust to cross-sectional dependence and slope heterogeneity. Specifically, we apply the cross-sectional autoregressive distributed lag (CS-ARDL) model for short- and long-run parameter estimation. The main findings are that governance and technological innovation both positively and significantly influence energy transition in the long run and short run. Economic growth affects energy transition positively, but trade openness affects energy transition negatively, while CO2 emissions have no significant impact on energy transition. Robustness checks, the common correlated effect mean group (CCEMG), and the augmented mean group (AMG) all validated these findings. Based on the findings, government officials are recommended to strengthen institutions, control corruption, and improve the quality of regulations in order to enhance the contributions of institutions to the transition to renewable energy.

The symmetric and asymmetric impacts of green energy, eco-innovation, and urbanization in explaining low-carbon economy for Pakistan

Over the past three decades, global economic development patterns have considerably affected the natural environment, and economies have endured a plethora of environmental concerns as a result of the negative effects of climate change. Among them, Pakistan is the fifth most vulnerable country, and climate change has harmfully affected the ecological and socio-economic conditions of the country. In this regard, this study aimed to investigate the role of green energy consumption, eco-innovation, and urbanization while explaining the dream of low-carbon economy and environmental sustainability in the context of Pakistan using annual time series dataset spanning from 1990 to 2020. The short-run and long-run associations among explained and explanatory variables were investigated using the symmetric, asymmetric, and quantile autoregressive distributed lag models. The findings of the study demonstrated that low-carbon economy, green energy consumption, ecological innovation, urbanization, GDP per capita, and labor force are cointegrated for the long-term association in symmetric, asymmetric, and quantile autoregressive distributed lag models. Furthermore, green energy consumption and effective eco-innovation are the most important paths to ensure environmental sustainability, while urbanization, GDP per capita, and labor force contribute negatively to the low-carbon economy. The findings of the study provide a policy framework for the development of a comprehensive strategy to promote environmental sustainability in Pakistan by emphasizing green energy consumption, ecological innovation, and controlled urbanization, as well as the incorporation of environment friendly policies into economic development policies.

Do transportation taxes promote pro-environmental behaviour? An empirical investigation

The transportation sector is a crucial driver of energy intensity and environmental degradation. Therefore, we aim to explore the nexus of transportation taxes, energy intensity, and CO₂ emissions for the BICS economies. The econometric approaches, CS-ARDL and PMG-ARDL, have been employed to compute the estimates. The long-run estimates of the green transportation tax variable are negatively significant in both energy intensity and CO₂ emissions models irrespective of the estimation technique. These findings imply that green transportation taxes help reduce energy intensity and CO₂ emissions in BICS economies. Conversely, in the short-run, the effects of transportation taxes on energy intensity and CO₂ emissions are mixed and inconclusive. Hence, transportation taxes are necessary to keep the polluters under control not only from the transport sector but also serve as a deterrent for other sectors as well.

Evaluating the role of renewable energy and technology innovations in lowering CO2 emission: a wavelet coherence approach

Environmental sustainability is one of the most critical issues that require efficient environmental and economic policies in modern times. Advancements in renewables and green technologies contribute significantly to sustained long-term development without affecting environmental quality. Several studies focus on the association of carbon dioxide emissions (CO₂e) with economic variables. However, they ignored the impact of technological innovations and renewable energy consumption on CO₂e in developed countries. Therefore, this study examines the relationship between CO₂e, energy consumption, gross domestic product (GDP), renewable energy consumption, and technology innovations in G-7 countries by employing cross-sectionally augmented autoregressive distributed (CS-ARDL) lag and wavelet coherence techniques during 1990-2020. The results depict that GDP and renewable energy consumption are inversely related to CO₂e. A 1% increase in CO₂e will decrease GDP and renewable energy consumption by 0.459 and 0.172% in the long run and by 0.471 and 0.183% in the short run in G7 countries. Technology innovations negatively impact CO₂e in the short run while positively influencing it in the long run. Considering the advancements in green technologies in different energy-dependent and manufacturing sectors is crucial for a sustainable environment in the long run. Such initiatives ensure the effective use of energy sources by limiting CO₂e in the atmosphere. Moreover, the dynamic common correlated effects mean group model confirms the reliability and effectiveness of the CS-ARDL. The wavelet coherence approach revealed a causality relation between CO2e and technology innovation in Italy, Japan, the UK, and the USA during the study period.

Information transmission in regional energy stock markets

Since markets are undergoing severe turbulent economic periods, this study investigates the information transmission of energy stock markets of five regions including North America, South America, Europe, Asia, and Pacific where we differentiated the regional energy markets based on their developing and developed state of economy. We employed time-frequency domain from Jan 1995 to May 2021 and found that energy stocks of developed regions are highly connected. The energy markets of North America, South America, and Europe are the net transmitters of spillovers, whereas the Asian and Pacific energy markets are the net receivers of spillovers. The results also reveal that the connectedness of regional energy markets is time and frequency dependent. Regional energy stocks were highly connected following the Asian financial crisis (AFC), global financial crisis (GFC), European debt crisis (EDC), shale oil revolution (SOR), and COVID-19 pandemic. Time-dependent results reveal that high spillovers formed during stress periods and frequency domain show the higher connectedness of regional energy stock markets in the short run followed by an extreme economic condition. These results have significant implications for policymakers, regulators, investors, and regional controlling bodies to adopt effective strategies during short run to avoid economic downturns and information distortions.

Financial integration and renewable energy consumption in China: do education and digital economy development matter?

Renewable energy is considered vital to addressing the issue of climate change and energy poverty. In recent times, empirics have tried to find the determinants of renewable energy consumption. Hence, the primary focus of the analysis is to estimate the impact of financial integration, education, and ICT on renewable energy consumption in China. In order to get the estimate of the variables, the analysis has applied the quantile ARDL model. The long-run estimates of the financial integration are positively significant at most quantiles, confirming the positive impact of financial integration on renewable energy consumption. Similarly, the long-run estimates of ICT are positively significant in almost all quantiles, confirming that digitalization helps increase renewable energy consumption in China. The long-term effect of education is significant at the higher quantiles. In the short run, the estimated coefficients of financial integration are positively significant at almost all quantiles; however, the estimated coefficients of ICT are positively significant in half quantiles. The short-run results of education are insignificant at most quantiles. In line with these results, several appropriate financial integration, digitalization, and education policies are recommended.

Impacts of renewable energy on output elasticities and implications for factor shares in European countries: fresh evidence from panel threshold models

The objective of this paper is to examine, for a panel of seven countries from the European Union, spanning the period 1986-2015, whether the use of renewable energy impacts their output elasticities of capital and labor and, thereby, influences the factor shares. By applying a set of models from threshold analysis, the analysis detects-for the first time-the presence of thresholds in the use of renewable energy with nontrivial consequences; notably, once the thresholds are crossed, the output elasticity of capital declines, while the output elasticity of labor rises. These changes in the elasticities indicate substantial changes in factor shares triggered by the identified threshold level of renewable energy consumption. This paper also finds changes in output elasticities of factors of production for other threshold variables including energy production from oil and gas or coal. These findings portray a complex and non-linear relationship between energy sources (e.g., renewables and non-renewables) vis-à-vis the economic growth level (e.g., GDP), with far-reaching consequences for factor shares from using renewables vis-à-vis non-renewables. Accordingly, it can be assumed that the changes in factor shares can, in turn, shape the incentives for the adoption of renewables within the selected European nations. Hence, future economic policies should emphasize the augmentation of renewable energy in the national energy system in order to sustain the rate of economic growth.

Globalization and renewable energy use: how are they contributing to upsurge the CO2 emissions? A global perspective

The present study major aim was to examine the impact of globalization, economic growth, population growth, renewable energy usage and nuclear energy on CO₂ emissions globally by taking the annual data varies from 1985 to 2020. Stationarity among study variables were tested via unit root testing, while nonlinear autoregressive distributed lag (NARDL) technique was used to demonstrate the linkages among variables with the estimation of long-run and short-run. Study results reveal that both in the short run and long run, negative globalization and economic growth shocks positively and negatively influence CO₂ emissions, respectively. Besides, higher population growth is found to positively influence CO₂ emissions while renewable energy consumption cannot influence the CO₂ emission figures. Lastly, positive and negative shocks to alternative nuclear energy consumption are evidenced to negatively influence CO₂ emissions both in the short run and long run. Hence, in line with these findings, several new policies and strategies are recommended for reducing carbon emissions globally.

Optimal utilization of ecological economic resources and low-carbon economic analysis from the perspective of Public Health

Introduction

China's urbanization process continues to deepen with social development, but the optimal utilization of ecological, economic resources and Public Health (PH) problems are becoming increasingly severe.

Methods

This paper analyses the optimal use of urban resources based on PH. Here, the public space of urban settlements is selected as the research object. Firstly, the connotation and essence of the ecological economy and Low-Carbon Economy (LCE) are analyzed. Secondly, the characteristics of public space in urban settlements are studied based on PH. The public space satisfaction evaluation model in urban settlements is constructed with five first-level and 12 second-level indicators. Finally, a questionnaire is designed to analyze urban households' outdoor activities and evaluate public space in settlements.

Results

The influencing factors of residents' satisfaction with public space in settlements are obtained through regression analysis. The results show that residents' satisfaction with the public space of the settlement is mainly evaluated from three aspects: the accessibility of public space, the integrity of public space, and the pleasure of public space. The influence coefficients are 0.355, 0.346, and 0.223, respectively, indicating that the influence degree of the three principal factors decreases in turn.

Conclusion

We can optimize the utilization of urban residential public space resources from the aspects of accessibility, integrity and pleasure, so as to promote residents to go to public spaces for outdoor activities and physical exercise, which is more conducive to the public health of residents.

Analysis and improvement of sports industry development and public health strategy under low-carbon economic structure

With the continuous development of society, various industries are rising and developing rapidly. Against this background, the energy crisis has come quietly. Therefore, to improve the quality of life of residents and promote the comprehensive and sustainable development of society, it is essential to enhance the development of the sports industry and formulate public health strategies under the background of a low carbon economy (LCE). Based on this, to promote the low-carbon development of the sports industry and optimize the formulation of social public health strategies, firstly, this paper introduces the low-carbon economic structure and its role in society. Then, it discusses the development of the sports industry and the necessity of perfecting public health strategy. Finally, based on LCE's development background, the sports industry's development situation in the whole society and M enterprises is analyzed, and suggestions are put forward to improve the public health strategy. The research results show that the current development prospect of the sports industry is extensive, and the added value of the sports industry will be 1,124.81 billion yuan in 2020, up by 11.6% year-on-year, accounting for 1.14% of Gross Domestic Product (GDP). Although industrial development declined in 2021, the added value of the sports industry accounts for an increasing proportion of GDP yearly, which shows that the sports industry is playing an increasingly important role in economic growth. And through the analysis of the development of M enterprise sports industry as a whole and in different directions, this paper shows that enterprises should reasonably control the development of various industries to provide impetus for the overall development of enterprises. The innovation of this paper lies in the innovative use of the sports industry as the primary research object, and its development under LCE is studied. This paper not only supports the sustainable development of sports industry in the future, but also contributes to improving public health strategy.

The effects of the oil price and temperature on food inflation in Latin America

The impacts on food prices of temperature, the oil price, the exchange rate and wages in the agricultural industry were examined via a structural vector autoregression model and panel Granger causality test, using monthly data between January 2003 and December 2020 for Latin American countries. The paper concerns how much the determinants affect food prices. Empirical findings show that the oil price and temperature can be significant factors for reducing food inflation. According to the result of variance decomposition, in general, a considerable part of food inflation was explained by the exchange rate, but its effect did not show any significant change in the long term. The impacts of the oil price and temperature were limited in the early months, but they created larger changes over time. Impulse response function and the Granger causality test also indicated that exchange rate was a crucial dynamic in explaining food inflation in all countries except Ecuador. This country successfully mitigated the negative effect of the exchange rate, but the oil price and temperature had an impact on food inflation. All results indicate that both monetary and fiscal policies are essential to control food prices. These countries can accomplish this by conventional policies or by radical institutional changes. Nevertheless, the oil price and temperature are external dynamics, and crucial in creating alternative policies to control food inflation.

An analysis of the environmental impacts of ethnic diversity, financial development, economic growth, urbanization, and energy consumption: fresh evidence from less-developed countries

Improving the quality of environmental indicators has become a global concern that necessitates the identification of possible channels through which environmental welfare can be enhanced worldwide. Against this backdrop, this current study aims to elucidate the environmental effects of ethnic diversity, controlling for financial development, urbanization, economic growth, and energy consumption in the context of 51 less-developed countries during the period from 1996 to 2016. For measuring the environmental impacts, we use both the ecological footprint and carbon dioxide emission figures of these countries. Overall, the cointegration analysis confirms the existence of long-run relationships among the study variables. Besides, the regression analysis reveals that ethnic diversity deteriorates environmental quality by surging the ecological footprint and carbon dioxide emission levels of the selected nations. Similarly, financial development and energy consumption are found to impose identical adversities on the environment while urbanization is evidenced to ensure environmental welfare. Lastly, for both the environmental indicators considered in this study, the environmental Kuznets curve hypothesis is verified from the findings. Hence, considering these key outcomes, a set of relevant environmental welfare-related policy interventions are recommended in the context of less-developed countries.

Does education matter in China? Myths about financial inclusion and energy consumption

China is the most polluted economy in the world, facing the challenges of increased CO₂ emissions. In this way, energy consumption is a key factor in CO₂ emissions. To this end, this study empirically examines the effects of financial inclusion and education on energy consumption by employing the ARDL approach for China during the period 1995-2019. The results suggest that financial inclusion has a positive effect on renewable energy consumption, but a negative impact on renewable energy and total energy consumption. The results show that education reduces non-renewable consumption and increases renewable energy consumption in the long term. Long-run and short-run findings are also consistent and robust in the sensitivity analysis. Based on findings, China should invest in the education sector and increase financial inclusion to reduce energy consumption to meet environmental sustainability.

A path towards carbon mitigation amidst economic policy uncertainty in BRICS: an advanced panel analysis

Continuing economic progress with less environmental damage and achieving a sustainable environment require switching from fossil fuels to green energy. However, alleviating environmental damage of growth has become a major challenge for BRICS where economic progress amidst rising urbanization pollutes the environment. In this context, the fight against climate change and actions towards environmental sustainability are greatly affected by rising economic policy uncertainty. Hence, this study assesses the role of green energy, urbanization, and economic growth in CO2 emissions in the presence of economic policy uncertainty in BRICS (excluding South Africa) from 1997 to 2020. The study used the cross-sectionally augmented auto-regressive distributive lag technique for revealing the short- and long-run effects of the analyzed variables on environmental quality. The empirical evidence suggested that the environmental Kuznets curve exists according to the recent framework of Narayan and Narayan Energy Policy 38:661-666, (2010) because even though economic growth increases CO2 emissions, its long-run effect is less than the short-run effect. Economic policy uncertainty boosts CO2 not only in the short-run but also in the long-run, evidencing that a sustainable environment requires decreasing the levels of policy uncertainty. For BRICS, switching towards green energy is a vital option to decrease environmental deterioration owing to the negative connection between green energy and CO2. The findings indicated that rapid urbanization is among the causes of high CO2. Furthermore, economic policy uncertainty influences both green energy and economic growth levels. Finally, policies are recommended to mitigate environmental deterioration.

The role of green growth, green financing, and eco-friendly technology in achieving environmental quality: evidence from selected Asian economies

Many countries are trying to achieve carbon neutrality targets by using environment-friendly technology and green growth. Thus, this analysis effort to identify the key role of green growth in improving the environmental quality. This study investigates the impact of green growth, income, environmental taxes, environment-friendly technology, renewable energy, and financial development in the context of 12 Asian economies over the period of 1990 to 2018. This study used the method of cross-section - augmented autoregressive distributed lag (CS-ARDL) to find out the impact of green growth and growth (GDP) on environment quality with some plausible variables under the scheme of environmental Kuznets curve (EKC). The study employed the method of CS-ARDL and for robustness the augmented mean group (AMG) method to find out the impact of green growth and GDP growth on environment quality with some plausible variables under the scheme of EKC. The results of CS-ARDL concluded that CO₂ is significantly affected by GDP growth, green growth, and technological change in the context of Asian economies. The GDP square is inversely and the GDP growth is positively related to the CO₂, indicating the presence of inverted U-shaped EKC in this region. But the inverse relationship between green growth and green growth square and concave EKC is observed in Asian countries. The study used the Dumitrescu and Hurlin panel test to gauge the causality between the variables. This study suggested that policymakers should focus on transforming the country's energy system in ways that will reduce energy-related CO₂ emissions faster than previously expected.

Have international remittance inflows degraded environmental quality? A carbon emission mitigation analysis for Ghana

Despite the considerable contributions of remittances to households and economic advancements, their environmental implications have received little attention in empirical research. This study was, therefore, conducted to help fill that gap, using Ghana as an evidence. In achieving the above goal, robust econometric methods that control for endogeneity, heteroscedasticity and serial correlation among others, were engaged for the analysis. From the results, the studied variables were first-differenced stationary and cointegrated in the long run. The elasticities of the predictors were explored via the FMOLS, DOLS and CCR estimators, and from the results, remittance inflows worsened the ecological quality in Ghana through high CO2 emissions. Also, population growth and energy utilization were not friendly to the country's environment; however, technological innovations improved environmental quality in the nation via low CO2 effusions. The VECM was employed to examine the path of causalities amidst the series, and from the results, there were bidirectional causalities between remittance inflows and CO2 emissions and between population growth and CO2 emanations. Also, a causation from energy utilization to CO2 effluents was discovered; however, there was no causality between technological innovations and CO2 exudates in the country. Based on the findings, it was recommended among others that, authorities should enact regulations to control the activities of polluting industries that are being financed by remittances. Also, households and individuals should minimize their use of remittances to finance carbon-intensive items, like automobiles and air-conditioners among others, that add to environmental pollution in the country.

Research and development intensity and its influence on renewable energy consumption: evidence from selected Asian economies

The main objective of this study is to investigate the impact of research and development (R&D) intensity on renewable energy consumption in selected Asian economies. We have relied on the autoregressive distributive lag (ARDL) method to get empirical estimates. The short- and long-run results show that a rise in R&D intensity increases renewable energy consumption in China and Japan. In the long run, energy intensity and financial development increase renewable energy consumption in China and India only. Among other control variables, a rise in CO₂ emissions causes renewable energy consumption to rise in all three economies in the long run. The trade increases renewable energy consumption in India and Japan in the long run. This study shows the important policy implications of promoting R&D and renewable energy consumption in the selected Asian economies.

Striving towards sustainable development: how environmental degradation and energy efficiency interact with health expenditures in SAARC countries

The previous studies focused on environmental issues, identifying their root causes, urging prompt action to reduce environmental degradation. In this context, the current article extends the literature by incorporating the ecological impacts on the health sector and the role of sustainable development. The present study adds to the body of knowledge by examining the relationship between CO₂ emissions, sustainable development, energy efficiency, energy intensity, and health expenditures for SAARC countries from 2000 to 2020. Fully modified OLS (FMOLS) and dynamic OLS (DOLS) are used and diagnostic tests to check the association between the variables. The empirical analysis validated the long-run impact of the examined factors on health expenditures. The results show that energy efficiency and sustainable development have a statistically significant negative effect on health expenditures, vice-versa for CO₂ emission. Energy efficiency, energy intensity, and CO₂ emissions have been shown to have a one-way causative relationship with health expenditures, but sustainable development and economic growth have a two-way causation relationship. The better health status of the SAARC economies necessitates the establishment of long-term development strategies, environmental sustainability, and an examination of the energy sector. This work's conceptual and empirical advances have significant policy ramifications for this part of the globe and its efforts to improve sustainability.

Do Agriculture Technologies Influence Carbon Emissions in Pakistan? Evidence based on ARDL technique

Pakistan is an agrarian country, and the usage of agriculture technologies has increased in this country over the period of time. Extensive use of agriculture technologies may have detrimental impact of environment quality through an increase in carbon dioxide emissions. This study examines the impact of agriculture technologies on carbon emissions in Pakistan by using the annual time series data for the period 1973-2018. For long-run and short-run analysis, autoregressive distributed lag model is applied and the results reveal that cointegration exists among the variables. Long-run results show a significant positive impact of pesticide and economic growth on carbon emission, whereas short-run results confirm the positive effect of economic growth on carbon emissions in Pakistan. This study has important policy implications, such as to increase sustainable economic growth through agriculture sector; there is a need to introduce green technologies that produce less carbon emissions.

The impact of green supply chain management practices on environmental performance during COVID-19 period: the case of discretionary companies in the G-20 countries

Purpose

This study investigates the impact of green supply chain management (GSCM) practices on environmental performance in firms operating in the discretionary sector in the G20 countries. The sample covers 749 firms for the period 2010–2020.

Design/methodology/approach

This study combines qualitative and quantitative data to examine the impact of the implementation of GSCM on accounting performance measured by the operating margin (OM) and return on assets (ROA). The authors also moderate the effects of Six Sigma and quality management (QM) and ISO 9000 and control for firm variables and COVID 19.

Findings

Using a panel data regression and structural equation modeling (SEM), results indicate that discretionary firms with internal solid GSCM practices combined with external environmental monitoring of suppliers are likely to outperform their peers in environmental issues. Using hierarchical regression, results indicate that both ISO 9000 and S&QM have moderating effects at some level of performance. Furthermore, environmental performance is positively correlated with accounting performance. This study contributes to the literature by addressing the impact of GSCM and the importance of reinforcing green and social regulations to protect the planet.

Originality/value

The paper is one of the first to measure GSCM triple components and account for COVID-19 in the context of discretionary companies and G20 countries. It highlights the impact of green initiatives to cope with major disruptions and decrease pollution and environmental disasters.

Does energy consumption, economic growth, urbanization, and population growth influence carbon emissions in the BRICS? Evidence from panel models robust to cross-sectional dependence and slope heterogeneity

This paper examined the nexus between economic growth, energy consumption, urbanization, population growth, and carbon emissions in the BRICS economies from 1990 to 2019. In order to yield valid and reliable outcomes, modern econometric techniques that are vigorous to cross-sectional dependence and slope heterogeneity were employed. From the findings, the studied panel was heterogeneous and cross-sectionally dependent. Also, all the series were first differenced stationary and co-integrated in the long run. The Augmented Mean Group (AMG) and the Common Correlated Effects Mean Group (CCEMG) estimators were employed to estimate the elastic effects of the predictors on the explained variable, and from the output of both estimators, energy consumption worsened environmental quality via high carbon emissions. Also, the AMG estimator affirmed economic growth to be a significantly positive determinant of carbon emissions. However, both estimators confirmed urbanization and population growth as trivial predictors of the emissivities of carbon. On the causal connections amidst the series, there was bidirectional causality between economic growth and carbon emissions, between energy consumption and economic growth, between economic growth and population growth, between energy consumption and urbanization, and between economic growth and urbanization. Lastly, a causation from urbanization to carbon emissions was unfolded. Policy implications are further discussed.

Quantile estimation of ecological footprint and economic complexity in emerging economies: The moderating role of increasing energy consumption

There are increasing debates on the relationship between economic complexity and environmental degradation. This study deepens our understanding of this nexus in 11 emerging economies given the moderating role of energy consumption while controlling for economic development, trade openness and population growth. The findings from the quantile regression technique reveal that emerging economies are characteristic of low energy consumption, leading to insignificant contributions of economic complexity to environmental degradation across the spectrum as they also have very low-trade openness. Further results show the invalidity of the EKC between energy use (such as fossil fuels) and environmental degradation in emerging economies. Moreover, the Environmental Kuznets Curve (EKC) between economic development and environmental degradation is valid especially for those countries in the low and median quantiles (Egypt, Indonesia, and Vietnam). Also, the EKC hypothesis between population and environmental degradation is valid only for countries in the high and highest quantiles (Korea Republic, Turkey, Mexico and Iran). Finally, the results revealed that trade openness strictly reduces environmental degradation across the spectrum. Policy implications, limitations of the study and direction for future research are discussed.

Modelling the effects of energy diversification on ecological footprint: evidence from Côte d'Ivoire

Energy diversification is a vital contribution to sustainable development. Many countries are accelerating the diversification of their energy mix to meet the challenges of the energy transition. This study aims to model and investigate the effects of energy diversification on the ecological footprint of production in Côte d'Ivoire. The study uses an autoregressive distributed lag model with structural breaks and covers the period 1971-2015. Energy diversification is measured by an "Energy Mix Concentration Index," a concentration indicator based on the Herfindahl-Hirschman Index. The results suggest that, in the short term, energy diversification reduces the ecological footprint of production in Côte d'Ivoire, and is conducive for environmental protection. In the long term, energy diversification also has a reducing effect on the ecological footprint of production up to a certain threshold where energy concentration increases the ecological footprint. The study finds that there is an optimal level of energy diversification that is ideal for achieving a lower impact of energy diversification activities and exploitation of energy production sources on the environment in Côte d'Ivoire. The commissioning of the Azito power plant in 1999, which produces electricity using natural gas, has also had a major impact, not only on the country's energy mix since then, but also on its ecological footprint of production.

The cyclical impact of green and sustainable technology research on carbon dioxide emissions in BRICS economies

This paper explored the asymmetrical relationships between green and sustainable technology research and environmental sustainability among the BRICS states from 1990 to 2018. The data was analyzed by second- and third-generation economic techniques such as slope heterogeneity and cross-section independence test, unit root test, structural break unit root test, panel cointegration with structural breaks cointegration tests, cross-section autoregressive distributed lags technique, augmented mean group, and Dumitrescu-Hurlin panel causality test. First, the results validated a long-run cointegration among variables. Second, the results showed that renewable energy consumption and positive shocks to green and sustainable technology research are proper to mitigate carbon dioxide emissions (short- and long-run). Third, gross domestic product, foreign direct investment, exports, and negative shocks to green and sustainable technology research increase carbon dioxide emissions. Fourth, the nexus between green and sustainable technology research and carbon dioxide emissions was counter-cyclical during economic expansion and contraction periods. Fifth, the impact of positive shocks to green and sustainable technology research on carbon dioxide emissions was more than the impact of negative shocks to green and sustainable technology research on carbon dioxide emissions.

The trade-off between energy consumption, economic growth, militarization, and CO2 emissions: does the treadmill of destruction exist in the modern world?

Militarization is crucial for the sovereignty of a nation; however, there are many environmental hazards associated with increased military spending. Previous panel studies mainly captured the short-run effects of militarization on the environment. Limited scholars determined the long-run environmental impacts of militarization but they mostly ignored possible cross-sectional dependence and heterogeneity problems in panel data. Our research highlights this deeply neglected area and examines the impact of militarization on the environment in 22 OECD countries by controlling economic growth, renewable energy, and fossil fuel consumption. Drawing on an extensive dataset from 1971 to 2020, we employed advanced econometric approaches robust against endogeneity, heterogeneity, and cross-sectional dependence. The results of the cross-sectional augmented autoregressive distribute lag (CS-ARDL) analysis indicate a positive contribution of militarization to CO₂ emissions implying that militarization is adding to the environmental degradation in OECD nations. This evidence proves the treadmill of destruction theory for OECD nations in the modern world. Economic growth and fossil fuels consumption increase CO₂ emissions, while renewable energy mitigates emissions. Moreover, economic growth Granger causes militarization. Our results suggest that reduction in militarization level and energy conservation strategies will not hamper the economic progress of selected OECD countries.

Levels, trends and socio-demographic determinants of infant and under-five mortalities in and around slum areas of Dhaka city, Bangladesh

Infant and child mortality are often used to monitor the progress of national population health programs. The data for this study was collected from selected urban slums where icddr,b has maintained the Health and Demographic Surveillance System (HDSS). Using the HDSS database, 6,666 married women were selected and interviewed in 2018 to collect data on socioeconomic status, pregnancy history and safe motherhood practices. The study examined levels and trends of infant and under-five mortality for three periods: 1990–1999 (Period 1), 2000–2009 (Period 2), and 2010–2018 (Period 3) and examined socio-demographic differentials of infant and under-five mortality for Period 3. From Period 1 to Period 3, under-five mortality declined by 68.2%, with child mortality (1–4 years) declining more than infant mortality (84% vs. 65%). In the regression models for Period 3, infant and under-five mortality were higher for working than non-working mothers (infant: OR = 1.35*, CI: 0.98, 1.86; under-five: OR = 1.34*, CI: 0.99, 1.82), lower for girls than boys (infant: OR = 0.77*, CI: 0.57, 1.03; under-five: OR = 0.77*, CI: 0.58, 1.03), higher for small-size than normal/big-size babies (infant: OR = 4.11***, CI: 3.00, 5.64; under-five: OR = 3.68***, CI: 2.70, 5.02), higher for babies delivered vaginally than by caesarean section (infant: OR = 1.79**, CI: 1.14, 2.97; under-five: OR = 1.87***, CI: 1.21, 2.88), higher for babies delivered with complications than no complication (infant: OR = 2.16***, CI: 1.48, 3.15; under-five: OR = 2.21***, CI: 1.55, 3.18), and higher for babies born after a short (<24 months) birth interval (infant: OR = 1.71*, CI: 0.96, 3.05; under-five: OR = 1.63*, CI: 0.93, 2.86) than firstborns. While substantial progress has been made in reducing under-five and infant mortality, neonatal mortality have declined less slowly. Targeted population health interventions addressing the socio-demographic drivers of infant mortality, with a focus on the urban poor, will help Bangladesh achieve Sustainable Development Goal 3.

Infant and under-five mortalities were higher for:•

Working mothers than non-working

•

Small-size babies than normal-size

•

Vaginally delivered babies than caesarean section

•

Babies delivered with complication than without

•

Higher for babies born after a short birth interval than firstborns.

Mitigating energy production-based carbon dioxide emissions in Argentina: the roles of renewable energy and economic globalization

The energy sector of Argentina is predominantly reliant on fossil fuels. Consequently, such fossil fuel dependency within the nation's power sector, in particular, has aggravated the environmental quality in Argentina by amplifying the nation's energy production-based carbon emission levels. However, keeping into consideration the international commitments pledged by Argentina under the Paris Accord and the Sustainable Development Goals agenda, it is pertinent for this South American country to curb its energy production-based emission of greenhouse gases, especially carbon dioxide. Against this milieu, this study examines the impacts of renewable electricity generation, economic globalization, economic growth, and urbanization on carbon dioxide emissions generated from the production of electricity and heat in the context of Argentina. Using annual frequency data from 1971 to 2016, recent econometric methods are applied to control for multiple structural breaks in the data. The major findings from the ecnometric analyses affirmed long-run associations between renewable electricity generation, economic globalization, economic growth, urbanization, and energy production-based carbon dioxide emissions in Argentina. Besides, enhancing renewable electricity output shares is found to curb these emissions while economic globalization and urbanization are witnessed to boost them. Moreover, renewable electricity generation and economic globalization are found to jointly reduce the energy production-related carbon dioxide emissions in Argentina. The results also validate the authenticity of the Environmental Kuznets Curve (EKC) hypothesis. Finally, the causality analysis reveals evidence of unidirectional causalities running from renewable electricity generation, economic globalization, economic growth, and urbanization to energy production-related carbon dioxide emissions in Argentina. In line with these findings, this study recommends several viable policies which can be implemented to help Argentina control the growth of its energy production-based carbon dioxide emissions.

Carbon Emissions and Socioeconomic Drivers of Climate Change: Empirical Evidence from the Logarithmic Mean Divisia Index (LMDI) Base Model for China

The main objective of the present study was to examine the impact of socioeconomic factors on environmental degradation or preservation using the logarithmic mean disivia index (LMDI). The study used the latest data from thirty Chinese provinces from 2012 to 2020. Pooled mean group (PMG) results were estimated to determine the long-term and short-term impact of the aforementioned compound variables on carbon emissions. The study results revealed that population growth, per capita GDP growth, and fossil fuel-led energy consumption, positively impacted environmental degradation in China at the provincial level. However, clean energy intensity and a transition towards renewable energy in China are helping to reduce carbon emissions. Similarly, clean energy intensity is also helping to lower carbon emissions. The study proposed that at the provincial level, joint efforts were required to control environmental degradation in China. The positive impact of renewable energy intensity on carbon emissions encourages the transition from fossil fuels to clean energy sources for environmentally friendly growth.

Long-run equilibrium relationship between energy consumption and CO2 emissions: a dynamic heterogeneous analysis on North Africa

Environmental protection and sustainable development are inextricably linked. This linkage is particularly crucial for North Africa, where the use of carbon-intensive energies has created environmental and economic challenges. Amazingly, limited studies on the connection between energy consumption and environmental quality has been conducted to help with policy options to minimize the above menace in the region. Inspired by the Sustainable Development Goals (SDGs) of the United Nations, this study contributed to filling this gap by examining the energy consumption-CO₂ emission nexus in North Africa for the period 1990 to 2018. In order to account for cross-sectional dependence, endogeneity, and slope heterogeneity that are mostly ignored by some conventional econometric techniques, this exploration adopted second generation econometric methods that are robust to the aforestated issues in its analysis. From the results, the studied panel was heterogeneous and cross-sectionally correlated. Also, the investigated series were first differenced stationary and cointegrated in the long-run. The cross-sectional augmented autoregressive distributed lag (CS-ARDL) and the dynamic common correlated effects mean group (DCCEMG) estimators were adopted to explore the elasticities of the explanatory variables and from the results, energy consumption worsened environmental quality in the region due to its positive influence on CO₂ emissions. Also, urbanization and economic growth increased the rate of CO₂ emissions in the countries. On the causal connections amid the series, bidirectional causalities between energy consumption and CO₂ emissions, between urbanization and CO₂ emission, between economic growth and CO₂ emissions, and between urbanization and energy consumption were unraveled. Finally, unidirectional causalities from economic growth to energy consumption, and from economic growth to urbanization were confirmed. It is recommended that countries in North Africa should shift to the consumption of clean energies to help them attain low-carbon economy. Unavailability of data for some periods was the major limitation of the study. Therefore, in future when such data become available, similar explorations could be conducted to confirm the robustness of the study's results.

A sectoral analysis of the role of Foreign Direct Investment in pollution and energy transition in OECD countries

The sustainable development agenda has been driving the global debate on environmental policy for several years now. Developed countries have stricter environmental controls and are under pressure from international agencies to cut pollution. However, many of these countries have been accused of using Foreign Direct Investment to shift their environmental burden to countries with lower environmental restrictions, rather than reducing their overall environmental impact. Should developed countries continue to transfer their emissions? What role does the energy structure of recipient countries play in this investment? A Panel Autoregressive Distributed Lag Model was carried out for a set of 15 OECD countries, from 2005 to 2018. The main findings upheld the Pollution Halo hypothesis. However, they also confirmed the Pollution Haven hypothesis, which was unexpected for developed countries, with their higher environmental standards. It seems that Foreign Direct Investment may increase pollution by increasing overall energy consumption, rather than by transferring polluting industries. Foreign Direct Investment inflows seem to be more environmentally friendly than inward stock, particularly in the electricity and services sectors. Energy transition could be achieved without the polluting effect of Foreign Direct Investment. Investment in the electricity sector may be a way of decoupling economic growth from pollution.

The Role of Large Cities in the Development of Low-Carbon Economy—The Example of Poland

The main objective of the article is to evaluate the investment activity of large cities in Poland in the area of developing a low-carbon economy in 2014–2020, co-financed by European Union funds. This article poses several research questions, namely: Do large cities with environmental problems actively obtain EU funding to develop a low-carbon economy? What are the main socio-economic and environmental determinants of the level of the EU funding absorption among large cities in the research area? The empirical research was conducted on the basis of the data from the Ministry of Investment and Economic Development in Poland, which is responsible for the implementation of cohesion policy funds and from the Local Data Bank of Statistics Poland. Under the 2014–2020 perspective, 223 such projects have been implemented for a total of PLN 21 billion (EUR 4.74 billion). The projects focused on: transportation, electricity, gaseous fuels, steam, hot water and air for air conditioning systems, and environmental and climate change activities. In terms of both the number and the value of EU funds spent, great variation has been observed. Analysis of the correlation relationships showed a highly positive correlation between selected indicators of investment activity in the field of low-carbon economy co-financed by EU funds (especially taking into account the value of investments per area) and socio-economic indicators of Polish metropolises. Metropolises with high demographic, economic, and financial potential have proven to be more effective beneficiaries. Interestingly, no correlation was found between investment activity in the low-carbon economy and the level of environment pollution in large cities. This means that, unfortunately, pro-environmental activities depend on the state of finances of the cities, and not necessarily on the actual needs, even taking into account the fact that the EU covers a large proportion of the costs.

An analysis of the asymmetric effects of natural gas consumption on economic growth in Pakistan: A non-linear autoregressive distributed lag approach

Natural gas is a vital energy resource that is used to produce the national output of Pakistan. On the other hand, since natural gas is a relatively cleaner energy resource compared to oil and coal, enhancing the level of natural gas consumption can be expected to promote economic growth while somewhat improving environmental quality in the process. Hence, it is pertinent to assess the economic growth effects associated with the consumption of such comparatively cleaner energy resources. Against this background, the main objective of this paper is to explore the asymmetric effects of natural gas consumption, controlling for financial development, on Pakistan's economic growth figure over the 1965-2019 period. The results from the Augmented Dickey-Fuller, Phillips-Perron, and Zivot-Andrews unit root tests confirm a mixed order of integration among the variables. Besides, the bounds test and the Gregory-Hansen co-integration analysis reveal evidence of long-run associations between economic growth, natural gas consumption, and financial development in the context of Pakistan. Moreover, the outcomes from the nonlinear autoregressive distributed lag model analysis show that in the short-run, positive changes in the natural gas consumption levels increase Pakistan's economic growth. On the other hand, in the long-run, positive and negative changes in natural gas consumption levels increase and decrease the nation's economic growth level, respectively. On the other hand, both positive and negative changes in the financial development level are found to reduce Pakistan's economic growth level in the long run only. Furthermore, the Hacker-Hatemi-J causality analysis verifies that natural gas consumption causally influences the economic growth level in Pakistan; thus, verifying the energy consumption-led growth phenomenon. In line with these key findings, several policy level suggestions are put forward for Pakistan to enhance its natural gas consumption level in order to boost its economic growth rate in the future.

Is there a tradeoff between financial globalization, economic growth, and environmental sustainability? An advanced panel analysis

In recent years, many empirical studies investigated the effects of globalization on the ecological footprint (EF). Most of these studies relied on the KOF index of globalization and studied the effects of total globalization and disaggregated impacts of economic, social, and political globalization on the EF. However, less attention has been given to financial globalization which can also influence the EF. Hence, this study investigates the association between financial globalization (FG), economic growth (GDP), and EF controlling population density (PD) in the selected West Asian and the Middle East (WAME) nations from 1990 to 2017. The study relied upon second-generation methods for checking stationary properties and Westerlund and other techniques to scrutinize cointegration. The evidence showed cointegration in the model. The long-run approximations from continuously updated fully modified (CUP-FM) and continuously updated bias corrected (CUP-BC) tests divulge that financial globalization is an important factor to promote ecological sustainability in the sample countries because it decreases EF. Population density exacerbates EF and worsens environmental deterioration in sample countries. The study detected the environmental Kuznets curve (EKC) between EF and economic growth in the presence of financial globalization and population density. Besides, financial globalization Granger causes EF, while the feedback effect exists between EF and economic growth. Based on these results, WAME economies can accomplish ecological sustainability and sustainable development by enhancing their financial globalization levels.

Strategies to achieve a carbon neutral society: a review

The increasing global industrialization and over-exploitation of fossil fuels has induced the release of greenhouse gases, leading to an increase in global temperature and causing environmental issues. There is therefore an urgent necessity to reach net-zero carbon emissions. Only 4.5% of countries have achieved carbon neutrality, and most countries are still planning to do so by 2050-2070. Moreover, synergies between different countries have hampered synergies between adaptation and mitigation policies, as well as their co-benefits. Here, we present a strategy to reach a carbon neutral economy by examining the outcome goals of the 26th summit of the United Nations Climate Change Conference of the Parties (COP 26). Methods have been designed for mapping carbon emissions, such as input-output models, spatial systems, geographic information system maps, light detection and ranging techniques, and logarithmic mean divisia. We present decarbonization technologies and initiatives, and negative emissions technologies, and we discuss carbon trading and carbon tax. We propose plans for carbon neutrality such as shifting away from fossil fuels toward renewable energy, and the development of low-carbon technologies, low-carbon agriculture, changing dietary habits and increasing the value of food and agricultural waste. Developing resilient buildings and cities, introducing decentralized energy systems, and the electrification of the transportation sector is also necessary. We also review the life cycle analysis of carbon neutral systems.

Do natural gas, oil, and coal consumption ameliorate environmental quality? Empirical evidence from Russia

Environmental degradation stemming from the combustion of conventional energy sources is not only a major factor behind climate change but it also poses an adverse impact on human health. Undoubtedly, fossil fuels are major drivers of economic growth; however, their detrimental environmental impacts are of global concern. In the literature, there is no comprehensive empirical evidence on the linkage between the use of different energy sources and carbon dioxide emissions in the context of Russia, a nation that is ranked third in the list of the top carbon dioxide-emitting global countries. Hence, this paper aims to scrutinize the relationships between oil consumption, natural gas consumption, coal consumption, and carbon dioxide emissions controlling economic growth for Russia over the 1990-2016 period. The findings from the econometric analysis indicate that carbon dioxide emissions in Russia have long-run associations with economic growth and consumption of oil, gas, and coal. The long-run elasticity estimates reveal that economic growth is not directly harming Russia's environmental quality. However, higher oil, gas, and coal consumption degrades environmental quality by boosting the level of carbon dioxide emissions in Russia. In addition, the results from the Granger causality analysis confirm the existence of both long and short-term causal connections among the variables of concern. In line with these findings, several policy recommendations to address the environmental challenges in Russia are put forward.

Revisiting the energy-economy-environment relationships for attaining environmental sustainability: evidence from Belt and Road Initiative countries

The Belt and Road Initiative (BRI) is an ambitious development project initiated by the Chinese government to foster economic progress worldwide. In this regard, this study aims to investigate the dynamics of energy, economy, and environment among 42 BRI developing countries using an annual frequency panel dataset from 1995 to 2019. The major findings from the econometric analyses revealed that higher levels of energy consumption, economic growth, population growth rate, and FDI inflows exhibit adverse environmental consequences by boosting the CO₂ emission figures of the selected developing BRI member nations. However, it is interesting to observe that exploiting renewable energy sources, which are relatively cleaner compared to the traditionally-consumed fossil fuels, and fostering agricultural sector development can significantly improve environmental well-being by curbing the emission levels further. On the other hand, financial development is found to be ineffective in explaining the variations in the CO₂ emission figures of the selected countries. Besides, the causality analysis shows that higher energy consumption, FDI inflows, and agricultural development cause environmental pollution by boosting CO₂ emissions. However, economic growth, technology development, financial progress, and renewable energy consumption are evidenced to exhibit bidirectional causal associations with CO₂ emissions. In line with these findings, several relevant policies can be recommended for the BRI to be environmentally sustainable.

Assessing Hybrid Solar-Wind Potential for Industrial Decarbonization Strategies: Global Shift to Green Development

The global energy mix is shifting from fossil fuels to combinations of multiple energy storage and generation types. Hybrid energy system advancements provide opportunities for developing and deploying innovative green technology solutions that can further reduce emissions and achieve net-zero emissions by 2050. This study examined the impact of an increasing share of wind and solar electricity production on reducing carbon intensity by controlling coal and lignite domestic consumption and the production of refined oil products in a world aggregated data panel. Data covering the last three decades were used for the analysis by the ARDL bounds testing approach. The results showed that an increasing share of wind and solar electricity production would be helpful to decrease carbon intensity in the short and long term. On the other hand, a 1% increase in coal and domestic lignite consumption increased carbon intensity by 0.343% in the short run and 0.174% in the long run. The production of refined oil products decreases carbon intensity by 0.510% in the short run and 0.700% in the long run. However, refining oil products is associated with positive and negative environmental externalities. The positive aspect depends upon the removal of harmful pollutants and the production of cleaner-burning fuels, while the negative part is related to the operational side of refineries and processing plants that may release contaminants into the atmosphere, affecting global air and water quality. Hence, it is crucial to improve processing and refining capacity to produce better-refined oil products by using renewable fuels in energy production. It is proposed that these are the most cost-effective pathways to achieve industrial decarbonization.
