Municipal climate action is becoming increasingly important. Municipal finance equalisation laws (KFAs) form the backbone of needs-based financing of local government in the German Länder. The question of whether and - if so - how climate protection and adaptation fit into these KFAs is now being investigated for the first time by FiFo in cooperation with Professor Thomas Döring (sofia Darmstadt). The second focus of the study will be the question of whether multi-annual tax revenues can make allocations more predictable for local authorities. The research project on behalf of the MHKBD NRW was launched on 7 November with an intensive exchange of ideas with North Rhine-Westphalian associations of municipalities.
