Obama Set to Order New Fuel Standards for U.S. Trucks

President Obama will announce Tuesday that the federal government will further tighten fuel efficiency for medium- and heavy-duty trucks, according to a White House official, as part of the president's ongoing effort to use his executive authority to address climate change.

Obama's directive to the Environmental Protection Agency and the Department of Transportation, which he will announce at the Safeway distribution center in Upper Marlboro, Md., marks the second time he has mandated a cut in fuel consumption and carbon emissions from larger trucks.  This category, which encompasses all vehicles weighing more than 8,500 pounds, ranges from large pick-up trucks and school buses to massive 18-wheel tractor-trailers.
