DP20006 Inequality along the European Green Transition
The EU aims for 42.5% green energy consumption by 2030. What are the effects of the European green transition on inequality? We answer this question using a heterogeneous-agent model with non-homothetic preferences for energy and non-energy goods, calibrated to European data. We study the impact of an increase in carbon taxes designed to meet the EU target under different revenue-recycling strategies. Redistributing tax revenues via uniform transfers reduces consumption inequality, shifts the welfare burden to high-income households, but leads to significant output losses. Subsidizing green energy producers boosts energy production, reduces output losses, and requires a smaller carbon tax to meet the EU target. However, it increases consumption and income inequality, with the highest welfare costs borne by low income and asset-poor households. Our findings highlight key trade-offs between equity and efficiency in green transition policies.
