Graphical abstract
A sizeable amount of scholarly work has been done on different aspects of financial, economic, and environmental factors. In the present study, the nonlinearity is determined between financial development and carbon dioxide emissions in the long-run and short-run periods. According to the finding, the continued financial development initially increases the carbon dioxide emissions in the short and long run. Simultaneously, the square term of financial development reduces carbon dioxide emissions and proves the inverted U-shaped hypothesis in the short and long periods. The consumption of fossil fuels produces carbon dioxide emissions, leading to environmental pollution. In contrast, renewable energy sources have fostered ecological sustainability by reducing CO
2
emissions in the long and short term. At the same time, a positive response from labor productivity to carbon dioxide emissions causes environmental pollution, while capital formation is not acknowledged as a significant contributor to CO
2
emissions. The Error Correction term has ascertained the reduction in error and convergence of the model from short to long term with a speed of 8% per annum. The study suggested that renewable energy and financial development should be indorsed for environmental preservation in developing European and Central Asian economies. Financial development in favor of low-cost renewables, advancing cleaner production methods, solar paneling, and electrification are a few possible remedies to achieve environmental sustainability in the short-run as well as long-run time frame.
Formulating a robust low-carbon strategy has now been critical to achieving sustainable economic development amid broad carbon emissions across the BRIC region thanks to rapid industrialization and international trade growth. Developing such a strategy requires measuring actual sustainability performance from the energy, economy and ecological perspectives in this region. Therefore, this study explores the relationship among BRIC countries’ energy, economic and environmental sustainability performance by applying a common weight data envelopment analysis (DEA)-like composite indicator approach. The indicators encompass a comprehensive, latest, appropriate and applicable set of indicators. The results reveal that China and Brazil outperform against other underlined countries of the region in achieving sustainability with an overall index score of 0.96. India stands in ranking on second with a steady and unchanged score in the region, followed by South Africa and Russia, standing in ranking on fourth and fifth, respectively, in this study. Inclusive scores of both countries indicate the actual and robust possible potential for better sustainability performances in the region. This study proposes a policy by lifting the cross-border trade for renewable energy to achieve long-term environmental sustainability in the BRICS region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
