Confounding its critics for the seeming intrusion of politics into all of its decisions, on April 29, 2014, the Supreme Court issued its decision in the EPA v. EME Homer City Generation and American Lung Assn. v. EME Homer City Generation matters. In a 6-to-2 decision, the Court ruled to uphold EPA's Cross-State Air Pollution Rule, which requires increased emissions reductions from 27 continental upwind states. This is a major victory for EPA, and reinforces its authority to act under the Clean Air Act ("CAA") to combat climate change.
Go to the head of the class if you know the difference between CAFE standards and CAFO standards: in January of 2011, new corporate average fuel economy ("CAFE") standards went into effect, requiring all automobile manufacturers to curb the amount of greenhouse gases ("GHGs") emitted from the tailpipes of Model Year 2012 cars. These revised CAFE standards were jointly designed by the National Highway Traffic and Safety Administration and the Environmental Protection Agency ("EPA"), and issued under the motor vehicle program (Title II) of the Clean Air Act ("CAA"). Before this time, the annually-updated CAFE standards did not include a GHG curb, and GHGs were not regulated under any part of the CAA.
