The aim of this paper is to explore the relationship between energy use, economic growth, and environmental pollution in Turkey for the period from 1968 to 2016 by using ARDL bounds test approach. Test findings show that an increase in economic growth and trade openness cause environmental degradation in all models. Although the energy consumption coefficient is positive in all models, it is statistically significant only in the model where the ecological footprint indicator is the dependent variable. Thus, while determining a positive relationship between environmental pollution and economic growth in Turkey, also it can be said that the energy consumption increases ecological footprint. The findings indicate that there is a need to consider not only pollution emissions but also the ecological footprint for environmental degradation. These results raise a number of policy recommendations for Turkey. The existence of an inverted-U shaped relationship between environmental degradation and economic growth actually demonstrate the successful long run sustainable growth in Turkey.

Abstract Globally we are at a crossroad whereby energy production and consumption in themselves is partly blamed for climate change issues and global warming menace. The question that comes to heart is do we stop seeking energy production and consumption? of course no. Thus, there is a need for innovation on part of economies as they seek energy for sustainable development. This country-specific study focuses on South African, which reflects the above highlights menace in no small measure where her economic growth trajectory is plagued with high CO2 emission. To this end, we explore the nexus between coal energy consumption, economic growth, renewable energy consumption and CO2 emission between annual periods of 1980–2017. This study applied a battery of econometric techniques to underscore the relationship between the outlined variables. According to the ARDL bounds test to cointegration in conjunction with Kripfganz and Schneider (2018) critical approximation p-values both affirm long-run equilibrium relationship between study variables. Empirical evidence gives credence to the growth-induced pollution emission in South Africa as reported by the Autoregressive distributed lag Method, fully modified ordinary least squares and dynamic ordinary least squares as robustness test for soundness of analysis. This finding suggests that South Africa's economic growth trajectory is not clean. This preposition is resonated with the result of coal energy consumption also dampening environmental quality. Financial development shows strong statistical strength to improve the quality of the environment. These outcomes are indicative for policymakers as there is urgent need to energy transition from conventional energy based on fossil fuel (coal energy) to renewable energy mix which is more environmentally friendly should be pursued in South Africa.

The unprecedented economic growth in recent decades has cultivated the exploitation of natural resources and over-consumption, leading to ecological deterioration and sustainability. The ever-increasing consumption in developing countries is creating a significant environmental strain. Thus, the industry and consumers’ environmental issues and their harmful effects on human health have led to concerns among researchers, scientists, academic communities, and policymakers. The present work examines the impact of different consumption value factors on sustainable consumption behavior concerning consumer choice in Pakistan and China. A cross-sectional study is conducted, and data are collected through a primary source questionnaire. A sample of 431 respondents is chosen from different cities in Pakistan, and a sample of 342 respondents is selected from China. Estimation techniques like descriptive statistics, frequency distribution, multicollinearity, R square, independent sample t-test, the coefficient of correlation, and regression analysis are used for the data analysis. The comparative results show that knowledge values (KVs) and emotional values (EMVs) significantly influence the choice behavior of respondents toward environmentally friendly products both in Pakistan and China. In contrast, social values (SVs) and conditional values (CVs) show insignificant influence. Furthermore, functional values (FVs) are significant in Pakistan while insignificant in the context of China, and environmental values (EVs) are significant in China although insignificant in Pakistan with regard to sustainable consumption behavior.

We aim to investigate the impact of environmental entrepreneurship and green innovations on CO2 emissions in highly polluting Asian economies. For empirical estimation, we have applied ARDL and NARDL models. In the short run, the linear estimates of environmental entrepreneurship are significant in China and India. The short-run non-linear estimates of environmental entrepreneurship are significant in the case of China, India, and Japan. Similarly, the short-run linear estimates of green innovations are significant in China, India, and Japan, whereas the non-linear estimated coefficients of green innovation appeared to be significant in India, Japan, and Russia. In the long run, the linear estimates of environmental entrepreneurship are negative and significant in three countries, namely China, Japan, and Russia. Similarly, the estimates of green innovations are negative and significant in China, India, Japan, and Russia. In the non-linear model, the estimated coefficients of positive shock in environmental entrepreneurship are significant and negative in the case of China, India, and Japan; while, the estimates of negative shock in environmental entrepreneurship are negative and significant in India only. نهدف إلى التحقيق في تأثير ريادة الأعمال البيئية والابتكارات الخضراء على انبعاثات ثاني أكسيد الكربون في الاقتصادات الآسيوية شديدة التلوث. للتقدير التجريبي، قمنا بتطبيق نماذج ARDL و NARDL. على المدى القصير، تعد التقديرات الخطية لريادة الأعمال البيئية مهمة في الصين والهند. التقديرات غير الخطية قصيرة المدى لريادة الأعمال البيئية مهمة في حالة الصين والهند واليابان. وبالمثل، فإن التقديرات الخطية قصيرة المدى للابتكارات الخضراء مهمة في الصين والهند واليابان، في حين يبدو أن المعاملات التقديرية غير الخطية للابتكار الأخضر مهمة في الهند واليابان وروسيا. على المدى الطويل، تكون التقديرات الخطية لريادة الأعمال البيئية سلبية ومهمة في ثلاث دول، وهي الصين واليابان وروسيا. وبالمثل، فإن تقديرات الابتكارات الخضراء سلبية وهامة في الصين والهند واليابان وروسيا. في النموذج غير الخطي، تكون المعاملات المقدرة للصدمة الإيجابية في ريادة الأعمال البيئية كبيرة وسلبية في حالة الصين والهند واليابان ؛ في حين أن تقديرات الصدمة السلبية في ريادة الأعمال البيئية سلبية وكبيرة في الهند فقط.

The need to mitigate global warming has led policymakers and other stakeholders to see further understanding of the driving forces behind CO2emissions. Financial development has been identified among the most influential factors. However, its importance has not been well explored in developing countries, especially in Africa. Several studies have explored the CO2emissions-effects of financial development in Africa but focused on the temporal aspect and overlooked the spatial dependence which has the potential to influence the estimated marginal effects. In so doing, they consider each country as an island which tends to suggest that there are no spatial spillover effects that could originate from countries’ proximity. In this study, such an inaccurate assumption is relaxed by deploying a spatial Durbin model to explore the spatial dependence in the financial development-CO2emissions nexus for 52 African countries between 1995 and 2017. Our results reveal a significant positive direct effect (0.020) on financial development in a given country and a significant positive indirect effect (0.074). Thus, our estimated marginal effects show a positive and significant total effect (0.095), indicating that a 1% increase in financial development will result in a net increase of CO2emissions of about 0.095%. This finding implies that financial development contributes negatively to the surge of CO2emissions in Africa. While the environmental Kuznets curve hypothesis is validated in the continent, renewable energy utilization is found to posit significant environmental effects. This finding is crucial to policymakers as it stands as a reminder about the role of the neighbourhood in designing and implementing environmentally friendly policies that aim at reducing pollution in Africa.

Abstract Singapore has been ranked in the most dynamic financial market and the highest ecological deficit country, indicating that the trade-off hypothesis may exist. The main goal of the present study is to probe the impact of financial development, economic growth, and human capital on ecological footprint in Singapore from 1980 to 2016. The outcomes obtained from the Auto Regressive Distributed Lag (ARDL) method have failed to provide a clear impact of financial sector development on ecological footprint. However, the Bayesian analysis reveals that both financial development and economic growth have a harmful influence on EF, while the impact of human capital is beneficial. A theoretical conclusion derived is that monetary expansion policies should be associated with improving human capital to achieve the United Nations SDGs in the context of Singapore. The findings of the study are of particular interest to policymakers for developing sound policy decisions for sustainable economic progress which is not at the cost of environment.

Les promesses et les engagements des gouvernements des pays riches ont été pris lors du sommet de la COP26 à Glasgow, ravivant ainsi l'espoir des nations de relever le défi du changement climatique. Ainsi, l'étude examine la complémentarité du développement financier et des émissions de carbone, tout en tenant compte de l'influence conditionnelle de la bonne gouvernance sous trois indicateurs désagrégés – la gouvernance économique, institutionnelle et politique pour les économies des BRICS, de la MONNAIE et du G7. Tout d'abord, l'étude révèle que le développement financier en fonction de l'indicateur adopté a des effets mitigés sur les niveaux de pollution de l'environnement. Plus précisément, le développement financier déclenche l'effet de pollution le plus élevé via le crédit national au secteur privé par rapport aux investissements directs étrangers, tandis que l'indice de développement financier réduit la pollution environnementale. Deuxièmement, la gouvernance économique favorise la qualité de l'environnement en réduisant la pollution de l'environnement grâce à une réglementation de la qualité. Troisièmement, la gouvernance institutionnelle par le biais d'un État de droit plus faible induit la pollution, tandis que le contrôle de la corruption s'oppose aux niveaux de pollution. En outre, seule la voix de la responsabilité soutient l'effet d'atténuation de la pollution de la gouvernance politique. Sur une analyse comparative bloc à bloc, l'efficacité de la gouvernance favorise la pollution environnementale dans les trois blocs économiques, mais à des amplitudes différentes, tandis que la voix de la responsabilité n'exerce un impact souhaitable significatif sur la pollution que dans les pays du G7. Enfin, les énergies renouvelables et la libéralisation du commerce exercent respectivement une influence négative et positive sur la dégradation de l'environnement. En la cumbre de Glasgow COP26 se hicieron promesas y compromisos de los gobiernos de las naciones ricas, lo que rejuvenece la esperanza entre las naciones para enfrentar el desafío del cambio climático. Por lo tanto, el estudio examina la complementariedad del desarrollo financiero y las emisiones de carbono, al tiempo que tiene en cuenta la influencia condicional de la buena gobernanza bajo tres indicadores desagregados: gobernanza económica, institucional y política para las economías BRICS, MINT y G7. En primer lugar, el estudio revela que el desarrollo financiero en función del indicador adoptado tiene efectos mixtos en los niveles de contaminación ambiental. Específicamente, el desarrollo financiero desencadena el mayor efecto de contaminación a través del crédito interno al sector privado en comparación con las inversiones extranjeras directas, mientras que el índice de desarrollo financiero reduce la contaminación ambiental. En segundo lugar, la gobernanza económica promueve la calidad ambiental al reducir la contaminación ambiental a través de la regulación de la calidad. En tercer lugar, la gobernanza institucional a través de un estado de derecho más débil induce a la contaminación, mientras que el control de la corrupción antagoniza los niveles de contaminación. Además, solo la voz de la rendición de cuentas respalda el efecto mitigador de la contaminación de la gobernanza política. En un análisis comparativo de bloque a bloque, la efectividad de la gobernanza promueve la contaminación ambiental en los tres bloques económicos, aunque en diferentes magnitudes, mientras que la voz de la rendición de cuentas ejerce un impacto significativo deseable sobre la contaminación solo en los países del G7. Por último, la energía renovable y la liberalización del comercio ejercen una influencia negativa y positiva en la degradación ambiental, respectivamente. Pledges and commitments from governments of wealthy nations were made at the COP26 Glasgow summit, thereby rejuvenating hope among nations to confront the climate change challenge. Thus, the study examines the complementarity of financial development and carbon emissions, while accounting for the conditional influence of good governance under three disaggregated indicators – economic, institutional, and political governance for the BRICS, MINT, and the G7 economies. First, the study reveals that financial development depending on the adopted indicator has mixed effects on environmental pollution levels. Specifically, financial development triggers the highest pollution effect via domestic credit to the private sector compared to foreign direct investments, while financial development index reduces environmental pollution. Secondly, economic governance promotes environmental quality by reducing environmental pollution through quality regulation. Third, institutional governance through weaker rule of laws induces pollution, while the control of corruption antagonizes pollution levels. Furthermore, only the voice of accountability supports the pollution-mitigating effect of political governance. On a bloc-to-bloc comparative analysis, governance effectiveness promotes environmental pollution in all the three economic blocs albeit at different magnitudes while the voice of accountability exerts a significant desirable impact on pollution only in the G7 countries. Lastly, renewable energy and trade liberalization exerts a negative and positive influence on environmental degradation respectively. تم تقديم تعهدات والتزامات من حكومات الدول الغنية في قمة غلاسكو COP26، مما جدد الأمل بين الدول في مواجهة تحدي تغير المناخ. وبالتالي، تبحث الدراسة في التكامل بين التنمية المالية وانبعاثات الكربون، مع مراعاة التأثير المشروط للحوكمة الرشيدة في إطار ثلاثة مؤشرات مصنفة – الحوكمة الاقتصادية والمؤسسية والسياسية لاقتصادات بريكس ومينت ومجموعة السبع. أولاً، تكشف الدراسة أن التنمية المالية التي تعتمد على المؤشر المعتمد لها تأثيرات متباينة على مستويات التلوث البيئي. على وجه التحديد، تؤدي التنمية المالية إلى أعلى تأثير للتلوث عن طريق الائتمان المحلي للقطاع الخاص مقارنة بالاستثمارات الأجنبية المباشرة، في حين يقلل مؤشر التنمية المالية من التلوث البيئي. ثانياً، تعزز الحوكمة الاقتصادية الجودة البيئية من خلال الحد من التلوث البيئي من خلال تنظيم الجودة. ثالثًا، تؤدي الحوكمة المؤسسية من خلال ضعف سيادة القوانين إلى التلوث، في حين أن السيطرة على الفساد تستعدي مستويات التلوث. علاوة على ذلك، فإن صوت المساءلة وحده يدعم التأثير المخفف للتلوث للحكم السياسي. عند إجراء تحليل مقارن بين الكتلة والكتلة، تعزز فعالية الحوكمة التلوث البيئي في جميع الكتل الاقتصادية الثلاث وإن كان ذلك بأحجام مختلفة في حين أن صوت المساءلة له تأثير مرغوب كبير على التلوث فقط في بلدان مجموعة السبع. وأخيراً، تؤثر الطاقة المتجددة وتحرير التجارة تأثيراً سلبياً وإيجابياً على التدهور البيئي على التوالي.

Using the provincial panel data of China during 2012-2019, the present study employed spatial Durbin error model to explore the spatial effect of the digital economy on energy intensity. The results show that both digital economy and energy intensity have spatial autocorrelation, showing the distribution characteristics of spatial aggregation. The digital economy has a significant negative influence on energy intensity. The result shows a significant spatial spillover effect of digital economy on energy intensity, and the development of the digital economy in neighboring regions reduces energy intensity in the central region. Additionally, industrial structure, urbanization, energy price, and foreign direct investment have a heterogenous impact on energy intensity. Thus, it is crucial to give importance to the development of the energy intensity, plan the spatial layout of the digital industry as a whole, drive the coordinated growth of the regional digital economy, quicken the upgrading of industrial structure, promote urbanization, perfect the energy price formation mechanism, raise the entry threshold for foreign direct investment, to effectively reduce the energy intensity, and facilitate the smooth realization of the "double carbon" goal.
