Whether environmental regulations impact economic competitiveness of economies, sectors and firms is a topic both complex and controversial. Prominent attempts to answer this is found in the Pollution Haven Hypothesis, which posits that stricter environmental regulations impose cost and reduce competitiveness. On the other hand, such a theory has been contradicted by the Porter Hypothesis that argues that well-designed environmental regulations can inspire innovation, cut carbon footprint, and enhance competitiveness. When this study finds cases supportive and dismissive of both these hypotheses across the world, cases were also found which can be termed as Neutral Hypothesis—that environmental regulations do not affect economic competitiveness. This paper analyzes relevant theoretical frameworks as well as empirical evidences concerning the impacts of environmental policies on various dimensions of competitiveness, such as productivity, innovation, trade, and investment, in order to identify strategies that help design effective environmental regulations which foster both environmental sustainability and economic prosperity, thereby contributing to a balanced “Green and Growth” paradigm and sustainable development.
