Jakob Kilian Bilan, Robert Birkmayer, Ewa Jarosz, Etienne Oriot and Clara Simões Coelho — a team of Sciences Po students — participated in the first EIB Climate Survey Hackathon, where they examined the social dimension of climate finance. Their project, Determinants of Altruistic Willingness-to-Pay for an Environmental Tax, focuses on Germany, Sweden and Italy to explore what motivates individuals to support climate policies that primarily benefit lower-income households. Drawing on data from the EIB Climate Survey and Eurostat, the team finds that climate concern and trust in government strongly influence support for such taxation, while older age groups are generally less willing to contribute. Their findings provide valuable insights for designing fair and effective climate tax policies.
