The impact of trade openness on environmental quality: an empirical analysis of emerging and developing economies

This study examines the impact of trade openness on environmental quality using a dynamic panel data model for 60 emerging and developing economies. We attempt to examine the trade-environment relationship for the period 2002 to 2012, employing Environmental Performance Index (EPI) and CO 2 emissions as the two indicators of environmental quality. The paper tries to fill in the lack of dynamic panel data models investigating trade-environment relationship in emerging economies. The fixed effects model elicits that trade openness improves EPI, albeit it increases CO 2 emissions. When corrected for endogeneity, trade openness was found to have no significant impact on EPI, though it escalates CO 2 emissions. GMM findings with EPI highlight that political factors improve environmental quality, whereas income and population have detrimental effects. In the GMM estimations with CO 2 emissions, trade openness, income, energy consumption and population were found to have deleterious effects on environmental quality. The empirical findings impart support to the contentions over the impact of trade on environmental quality. Efficacious economic, energy, infrastructural and institutional policies hold the key to environmental sustainability in emerging economies.
