Global Social Policy, Ahead of Print.
Decarbonization, environmental protection, and sustainable development are more topical than ever. Despite long-standing debates about the regressive profile of environmental taxes, the welfare state’s role in buffering adverse distributive impacts of climate policy is largely unexplored. We examine if social policy shields households from falling into poverty due to environmental taxes tied to consumption. We specifically focus on the importance of income replacement in social insurance and social assistance. To enable detailed assessments of the distributive outcomes of environmental policy, we impute environmental taxes into the European Union Statistics on Income and Living Conditions (EU-SILC). Our comparative analysis of 26 European countries indicates that the welfare state protects households from relative income poverty due to environmental taxes. Moreover, comparisons between educational groups suggest that both social insurance and social assistance play different yet complementary roles in reducing socio-economic gradients in poverty related to environmental taxes.
