Law360, New York (June 27, 2012, 3:45 PM EDT) -- The U.S. Court of Appeals for the District of Columbia Circuit has, on June 27, 2012, in Coalition for Responsible Regulation v. U.S. Environmental Protection Agency, upheld a suite of EPA greenhouse gas (GHG) regulations in a sharp rebuke to industry and state petitioners attempting to overturn these rules.
The court’s unsigned per curium opinion primarily addressed four controversial EPA rules promulgated pursuant to the federal Clean Air Act (CAA):
The endangerment finding;
The tailpipe rule;
The timing rule; and
The tailoring rule.
