President Barack Obama on May 21 signed a presidential memorandum directing the U.S. EPA and the U.S. Department of Transportation to develop a National Policy that for the first time will put CAFE and greenhouse-gas limits on medium- and heavy-duty trucks. The regulations forming the National Policy will apply to model years 2014-2018. While the National Policy applies to trucks, the already approved National Program applies to light vehicles. In addition to creating a National Policy, Obama in the May 21 signing ceremony directed the agencies to extend the National Program's current scope (MY2012-2016) to MY2017 and beyond. The National Program, announced by Obama a year ago, recently was codified into law and sets a final target for MY2016 of 35 mpg for the U.S. fleet. The EPA and the U.S. DOT's NHTSA unit will work to set overall and annual targets for both programs, issuing specific proposals at some future date. In a press release, the White House pointed out that medium- and heavy-duty trucks on U.S. roads consume more than 2 million barrels of oil every day and average 6.1 mpg. Obama used the signing ceremony to direct the U.S. Department of Energy to provide "increased support for the deployment of advanced-technology vehicles" and to direct the EPA "to reduce non-greenhouse-gas pollutants from motor vehicles."
