The impacts of renewable energy, financial inclusivity, globalization, economic growth, and urbanization on carbon productivity: Evidence from net moderation and mediation effects of energy efficiency gains

Although the relevance of establishing low-carbon economic growth has been extensively highlighted in the Paris Agreement and the Sustainable Development Goals declarations, the analysis of the macro-economic determinants of carbon productivity has remained overlooked in the literature. Therefore, this study makes a novel attempt to evaluate whether energy efficiency gains, along with renewable energy use, financial inclusivity, economic growth, globalization, and urbanization, improve carbon productivity in the emerging seven countries between 2007 and 2018. Moreover, the study contributes to the liter-ature by predicting the net moderating and mediating effects of energy efficiency improvements on carbon productivity. The findings support that enhancing the level of energy use efficiency by 1% helps to improve carbon productivity by around 0.3% in the long run. In addition, the predicted net effects reveal that energy efficiency gains exert a moderating effect on the level of carbon productivity and reverse the negative impact of financial inclusivity, trade globalization, and urbanization on carbon productivity. However, energy efficiency gains cannot moderate to neutralize the carbon productivity-inhibiting impact associated with economic growth. Moreover, the analysis shows that energy efficiency gains mediate to jointly boost carbon productivity alongside higher renewable energy use. Lastly, financial globalization is evidenced to enhance carbon productivity in the emerging seven countries in the long run. Accordingly, a set of relevant policies are recommended.(c) 2022 Elsevier Ltd. All rights reserved.
