Obama calls for more fuel efficiency for big rigs

President Barack Obama is ordering federal agencies to work up national mileage and emissions standards for big rig and work trucks for the first time, seeking to limit pollution from the large vehicles that contribute a disproportionate share of it.

In a ceremony in the Rose Garden Friday Obama also ordered federal agencies that have already brought out new standards for cars and light trucks for the 2012-2016 model years to begin work on even stronger rules for 2017 and beyond.

Obama said he would like to see vehicles 20 years from now run on half the fuel they do today and produce half the pollution.
