New rules target GHG and fuel economy standards for cars, light trucks

Posted on October 14, 2010 by

USA’s Environmental Protection Agency (“EPA”) and the U.S. Department of Transportation (DOT) have signed a notice of intent jointly create rules that would propose stringent legal greenhouse gas (GHG) and fuel economy standards for model years 2017-2025 for cars and light trucks. Standards have already been established for the 2016 model year, with cars and light trucks targeted to achieve 35.5 miles per gallon and an emissions limit of 250 grams per mile of carbon dioxide-equivalent by that year.

The recent notice asks for public comments on four potential targets for reducing emissions beyond 2016: 3 percent, 4 percent, 5 percent, and 6 percent per year. A 3-percent improvement in emissions would result in a 47 mile-per-gallon fuel economy standard and emissions of 190 grams per mile in 2025. The notice states that the agencies will issue a proposed rule by September 30, 2011, and a final rule by July 31, 2012.
