We empirically investigate the existence of the Environmental Kuznets Curve (EKC) focusing on a sample of 39 countries in the period 1996-2014. Using an interaction model, we also analyze whether the effectiveness of environmental taxes in reducing CO 2 emissions depends on the quality of political institutions. Our results show that the inverted U-shaped relationship between environmental stress and economic development holds independently of the quality of political institutions and environment related taxes. Moreover, an increase in the environmental tax revenue has the expected reducing effect on environmental degradation only in countries with more consolidated democratic institutions, higher civil society participation and less corrupt governments. Our findings also show that the effects on environmental stress of revenue neutral shifts to different tax sources depend not only on the quality of political institutions, but also on the kind of externality the policymaker aims at correcting.
