Regional policy analysis in Germany

This article discusses improvements of regional (within-country) policy analyses focusing on Germany. Policy results from the literature and own model simulations of the current EU climate policy with carbon border adjustments highlight significant differences in policy results across EU countries and German regions. Whether carbon border adjustments have a significant average effect on the entire EU is questionable. Because official and constructed regional German data sets are incomplete or not publicly available and compilation methods are not standardized, the public provision of a harmonized, comprehensive, up-to-date data set, at least with federal state level resolution, is advisable.
