DOT, EPA Propose the Nation’s First Greenhouse Gas and Fuel Efficiency Standards for Trucks and Buses
"The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Transportation (DOT) today announced the first national standards to reduce greenhouse gas (GHG) emissions and improve fuel efficiency of heavy-duty trucks and buses. This comprehensive national program is projected to reduce GHG emissions by about 250 million metric tons and save 500 million barrels of oil over the lives of the vehicles produced within the program’s first five years....
