Climate change poses challenges for public budgets due to damage alleviation, adaptation and mitigation. As climate change is found to materialize even faster (IPCC, 2021), thus with demands expected to grow, there is need for quantification of these future demands and their evaluation. In the aftermath of Corona and its very budget demands, such knowledge of and frameworks to support prioritization in these climate change related public expenditures is particularly crucial. The here proposed project develops a quantitative framework to inform decision makers in their prioritization, integrates their specific information demand from the very beginning, and discusses results with them. In addition, the overall framework of climate-robust pathways towards carbon neutrality are employed to develop guidelines for emission compensation, as needed for ESG (Environment, Social, Governance) monitoring schemes of companies and the finance sector, in order to support fiscal sustainability.
