The EPA today formally determined that greenhouse gas (GHG) pollution endangers human health and the environment. Under a Supreme Court ruling, the endangerment finding is needed before the EPA can regulate carbon dioxide and five other GHGs released from automobiles, power plants, and factories under the federal Clean Air Act. This finding sets the stage for EPA to finalize the GHG standards proposed earlier this year for new light-duty vehicles as part of the joint rulemaking with the Department of Transportation. It also allows EPA to move forward with its "tailoring rule", which will require major sources of GHGs to take steps to limit emissions from new facilities by using Best Available Control Technology (BACT).
