Overview

Embracing energy efficiency (EE) and renewable energy (RE) is essential for improving environmental quality. This research investigates the asymmetric impacts of EE, RE, and other factors on CO 2 emissions in BRICS (i.e., Brazil, Russia, India, China, and South Africa) countries from 1990 to 2014. In contrast to previous studies, the present study considers EE as a major cause of CO 2 emissions in BRICS countries. By using the new hidden panel cointegration and nonlinear panel autoregressive distributive lag model, this study is the first of its kind that unfolds the asymmetric links among EE, RE, and CO 2 emissions. Findings clearly explain that the impact of the selected variables on CO 2 emissions is asymmetric, and both EE and RE help to lower CO 2 emissions in BRICS countries. In the long run, positive shocks in EE and RE can significantly mitigate CO 2 emissions in BRICS economies. In particular, a 1% fluctuation in the positive sum of EE reduces CO 2 emissions by 0.783% in the long run. On the other hand, a 1% fluctuation in the positive component of RE reduces CO 2 emissions by 0.733%. Moreover, individual country estimates suggest the heterogeneous effects among BRICS countries. Based on the empirical findings, policymakers should consider the asymmetric behavior of the EE, RE, and economic growth while formulating, energy, environment, and growth policies of BRICS countries.
