This document discusses a project between IEEP and Statistics Sweden to develop methodologies for quantifying adaptation costs and accounting for adaptation expenditures. The project aims to determine additional funding needed for adaptation and mainstream adaptation into the next EU budget. It will develop methodologies to account for and classify adaptation expenditures and calculate adaptation costs, which poses challenges around incompatible EU and national accounting systems and statistical confidentiality when considering autonomous adaptation measures. The document also examines using scenario analysis and probabilities to project impacts and budgets given uncertainty, and analyzing historical climate data to potentially predict average temperature exceedances on a monthly basis.
