Abstract

In 1975, Congress passed the Energy Policy and Conservation Act (EPCA), requiring standards for Corporate Average Fuel Economy (CAFE), and charging the U.S. Department of Transportation’s (DOT) with the establishment and enforcement of these standards. The Secretary of Transportation has delegated these responsibilities to the National Highway Traffic Safety Administration (DOT/NHTSA). Following an extended period of stable CAFE standards, NHTSA increased standards in 2003 for light trucks produced during 2005-2007 and developed new attribute-based standards in 2006 for light trucks produced during 2008-2011. In 2007, Congress passed the Energy Independence & Security Act (EISA), which updated EPCA by requiring, among other things, maximum feasible attribute-based CAFE standards that achieve at least 35 mpg by 2020. Rulemakings completed in 2009 and 2012 established new fuel economy standards for light vehicles produced during 2012-2016 and 2017-2021, respectively.
