英文摘要	Hydrofluorocarbons are a potent greenhouse gas, yet there remains a lack of quantitative estimates of their social cost. The present study addresses this gap by directly calculating the social cost of hydrofluorocarbons (SC-HFCs) using perturbations of exogenous inputs to integrated assessment models. We first develop a set of direct estimates of the SC-HFCs using methods currently adopted by the United States Government and then derive updated estimates that incorporate recent advances in climate science and economics. We compare our estimates with commonly used social cost approximations based on global warming potentials to show that the latter is a poor proxy for direct calculation of hydrofluorocarbon emissions impacts using integrated assessment models. Applying our SC-HFCs to the Kigali Amendment, a global agreement to phase down HFCs, we estimate that it provides US$202037 trillion in climate benefits over its lifetime. Expediting the phase-down could increase the estimated climate benefits to US$202041 trillion. Hydrofluorocarbons are a class of important greenhouse gases, and quantitative estimates of their social cost are still lacking. This research develops a set of direct estimates of their economic costs and shows their rapid phase-down could lead to large climate benefits.
