Central specifications show high global SCC values (median, US$417 per tonne of CO 2 (tCO 2) 66% confidence intervals, US$177–805 per tCO 2) and a country-level SCC that is unequally distributed.
Here we estimate country-level contributions to the SCC using recent climate model projections, empirical climate-driven economic damage estimations and socio-economic projections. Although useful in an optimal policy context, a world-level approach obscures the heterogeneous geography of climate damage and vast differences in country-level contributions to the global SCC, as well as climate and socio-economic uncertainties, which are larger at the regional level.
The social cost of carbon (SCC) is a commonly employed metric of the expected economic damages from carbon dioxide (CO 2) emissions.
