There are rumours that the EPA has sent along a proposed endangerment finding for greenhouse gases to the White House. This is big news and would get the new Administration closer to announcing the finding by Earth Day. The announcement would lead to the use of the Clean Air Act to regulate GHGs… but there’s been much debate as to the scope of action that would be required if the EPA in fact makes an ‘endangerment finding’. Critics have said the finding would require the regulation of everything from big industry to small sources – far broader than Canada’s plan to regulate only large industrial emitters.
I would think that any endangerment finding would have to somehow narrow the finding to only large emitters or large emissions of GHGs (or find some other way to exclude coverage of offices, homes, and other small sources).
Looking foward to seeing the actual finding (… or to see the legislation they’ll be able to push through if using the CAA is the other option).
