Public Comment on the International Foundation for Valuing Impacts’

Those estimates from the literature (specifically, the Climate Impact Lab’s DSCIM model and RFF’s GIVE model) were then adjusted for inflation and the time of release of the pulse of CO2 modeled in the literature (i.e., 2023 versus 2020). [...] Do you agree with the approach taken in establishing the Social Cost of Carbon within the methodology, including the averaging of GIVE and DSCIM to determine the value factor? Why or why not? 1b. [...] Do you agree with the approach taken in establishing the Social Cost of Carbon within the methodology, including the averaging of GIVE and DSCIM to determine the value factor? Why or why not?” I agree with the approach. [...] While the use of GWPs is widespread, in the context of economic valuation, GWPs do not comprehensively account for the differences in the social costs of different greenhouse gases. [...] The ratio of the social cost of a non-CO2 gas to that of CO2 determines the degree of error from the use of the GWP approach.
