About this Site

This site was designed to highlight some of the most significant efforts to incorporate the Social Cost of Carbon (SCC) in policymaking across the United States, so that decisionmakers, advocates, and other stakeholders better understand new ways to advance progress on climate change.

The SCC was developed by the federal government’s Interagency Working Group on the Social Cost of Greenhouse Gases (IWG), whose work began in 2009. The official IWG SCC estimates have been updated over time, most recently in 2016. The IWG’s SCC has been used in over 100 federal actions, including regulations and environmental impact statements, in an effort to internalize climate effects into the decisionmaking process. The contents of this website refer to the SCC estimate developed by the IWG, for reasons discussed here.

Staff members at the institute have published extensive research on the SCC and engaged in dozens of policy proceedings to encourage its proper use in regulations, environmental impact statements, and a variety of policies. More detail about our work on the SCC and numerous other issues can be found at policyintegrity.org
