The environment has received particular concern since the 1950s when countries began to experience the negative impacts of environmental degradation. This study employs cointegration and causality analyses to explore the influence of stringent environmental policies and business regulations on economic growth between 2000 and 2015 in the Group of Seven and BRICS economies. The causality analysis shows that business regulations have a significant effect on economic growth in the short run, while stringent environmental policies have no significant effects during that time. The cointegration analysis, however, reveals a mixed interaction among stringent environmental policies, business regulations, and economic growth depending country specific characteristics.
