"As we learn more and more about the tenor of the Trump transition, a key part of its regulatory rollback strategy on climate change is coming into focus.
It seems increasingly likely that the Trump administration would either alter, or attempt to stop using entirely, an Obama-era metric known as the 'social cost of carbon' in its federal rule-making processes. And that could have have major effects on the way environmental policies are written (or unwritten) in the coming years.
A recent, highly controversial questionnaire the transition team sent to the Department of Energy requested a list of all 'employees or contractors who have attended any Interagency Working Group on the Social Cost of Carbon meetings,' as well as emails and other materials associated with those meetings. It also asked a variety of questions about the assumptions that went into calculating the social cost of carbon."
