This research article analyzes the relationship between environmental regulation and carbon emissions reduction in Brazil, Russia, India, China, and South Africa (BRICS countries) from 1995 to 2016. Using advanced econometric analysis, it finds that environmental regulations play a positive role in reducing carbon emissions. The results confirm that current environmental control measures in the BRICS countries are successfully achieving pollution reduction targets. Environmental regulations help establish an inverted U-shaped relationship between income and pollution, indicating that economic development alone cannot control emissions and requires environmental regulation.
