EU IPCEI State Aid Dataset

This dataset contains descriptive information and state aid data for all Important Projects of Common European Interest (IPCEI) of the European Union (EU). It compiles the amounts of state aid expended by each EU member state in each project and computes ratios to express to which extent a country is over- or underrepresented in these projects. This dataset was compiled in function of the following article. Please cite as De La Cruz, R. (2026) A “Common” European Interest? Explaining Variation in IPCEI State Aid Between EU Member States.
