American Electric Power Company v. Connecticut, 564 U.S. 410 (2011), was a United States Supreme Court case in which the Court, in an 8–0 decision, held that corporations cannot be sued for greenhouse gas emissions (GHGs) under federal common law, primarily because the Clean Air Act (CAA) delegates the management of carbon dioxide and other GHG emissions to the Environmental Protection Agency (EPA). Brought to court in July 2004 in the Southern District of New York, this was the first global warming case based on a public nuisance claim.
