NAHB is pleased by the U.S. Supreme Court's decision to hear American Chemistry Council, et al. v. U.S. Environmental Protection Agency (EPA) to challenge EPA's plan to regulate greenhouse gas emissions under the Clean Air Act. 

Because of the way EPA has interpreted the statute, many NAHB members might be forced to obtain an expensive pre-construction permit for greenhouse gas emissions, which would bring most multifamily and mixed-use development to a halt. Some single-family and potentially even master-planned community development would also be affected, according to NAHB.

NAHB is part of a coalition that includes the American Chemistry Council, the American Petroleum Institute, the National Association of Manufacturers, the American Fuel and Petrochemical Manufacturers and the National Oilseed Processors Association. Briefing in this case will take place during the fall and winter of 2013. Oral argument will be held in February 2014 and a decision is expected in late spring 2014.
