EPA, DOT propose GHG/fuel efficiency standards for trucks, buses


The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Transportation (DOT) have jointed proposed a rule that would establish the first-ever greenhouse gas (GHG) emissions and fuel-efficiency standards for buses and heavy-duty trucks. In a joint release on October 25, the agencies said that the new standards will result in GHG emissions reductions amounting to 250 million metric tons over the program’s first five years and will save 500 million barrels of oil over the lives of vehicles produced during that period. The standards would apply to buses, combination tractors, heavy-duty pickups and vans, and vocational vehicles, beginning with the 2014 model year; reductions in carbon dioxide (CO2) emissions and fuel consumption would range from 7 to 20% depending on the category of vehicle. Interested parties will have 60 days to submit comments once the proposal is published in the Federal Register.
