In its proposal to repeal the Clean Power Plan (CPP), the Environmental Protection Agency (EPA) has devalued the social cost of carbon (SCC) and disregarded the global benefits from the CPP. Following President Trump’s executive order rescinding the SCC, this approach could be used to revisit existing environmental rules. Despite the pushback on carbon pricing at the federal level, states are increasingly using the social cost of carbon as a metric to measure and reduce their climate impacts.
