The distributive politics of the green transition: a conjoint experiment on EU climate change mitigation policy

In the fight against climate change, the European Union has developed a new growth strategy to transform Europe into the first climate-neutral continent by 2050. To support EU member states in their transition towards greener economies, climate change mitigation policies are being implemented at the EU-level. However, such policies can be designed in different ways, and gaining citizens' support is crucial for the political feasibility of the European green transition. Drawing on data from an original conjoint experiment conducted in Germany (N = 5,796), this article investigates how policy design shapes public support for EU climate change mitigation. To this end, the study theoretically and empirically distinguishes four policy dimensions that address the distributive politics of the European green transition: sectoral scope, social spending, financing structure and cross-country distribution. The results confirm that all four policy dimensions significantly impact public support. Specifically, the study reveals that support is greatest for EU policy packages that target financial support at the renewable energy sector, include social investment policies, are financed by increasing taxes on the rich, and distribute resources across EU member states based on population size. Furthermore, citizens' sensitivity to the policy design varies slightly by income position, left-right ideology and climate attitudes.
