To better understand the role of environmental regulations in carbon emissions mitigation, this study takes a step to offers a new perspective on the role of environmental regulations in pollution reduction for Brazil, Russia, India, China, and South Africa. To this end, the study employs panel data econometric tools for data spanning from 1995 to 2016.
