The social cost of carbon - factsheet (2016)
EPA and other federal agencies use estimates of the social cost of carbon (SC-CO2) to value the climate impacts of rulemakings. The SC-CO2 is a measure, in dollars, of the long-term damage done by a ton of carbon dioxide (CO2) emissions in a given year. This dollar figure also represents the value of damages avoided for a small emission reduction (i.e. the benefit of a CO2 reduction).
