WASHINGTON (AP) _ Fire trucks and concrete mixers, semis, heavy-duty pickups and all trucks in between will, for the first time, have to trim fuel consumption and emissions of heat-trapping gases under new efficiency standards being announced Tuesday by President Barack Obama.
The White House says the standards the president was announcing will save businesses billions of dollars in fuel costs, help reduce oil consumption and cut air pollution. The standards apply to vehicle model years 2014 to 2018.
Senior administration officials said the new targets affect three categories of vehicles.
Big rigs or semis will have to slash fuel consumption and production of heat-trapping gases by up to 23 percent. Gasoline-powered heavy-duty pickups and vans will have to cut consumption by 10 percent, or by 15 percent if the vehicles run on diesel fuel.
