Short summary
Integrated Assessment Models are widely used by researchers to assess future emissions and the performance of climate policies. Bringing together insights from these models with information at the country level has remained difficult, as they usually provide results for a limited number of highly aggregated regions. We address this issue by presenting a novel algorithm designed to downscale regional outcomes to the country level and show the results for a current policy and a 1.5C scenario.
