As the U.S. Congress has failed to pass meaningful climate legislation, the EPA has initiated a series of regulations under the Clean Air Act designed to recognize greenhouse gases as endangering human health and welfare, and set greenhouse gas emission standards for vehicle fleets and for major stationary sources. Unsurprisingly these efforts have been challenged in the DC Circuit Court of Appeals. This paper discusses both the substantive and procedural issues surrounding the cases, all of which merit attention: in the absence of viable climate legislation these decisions will have important bearing on the extent to which the United States is able to address its greenhouse gas emissions.
