(WASHINGTON) -- The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Transportation are proposing new national standards to improve fuel efficiency and reduce greenhouse gas (GHG) emissions from heavy trucks and buses.
"These new standards are another step in our work to develop a new generation of clean, fuel-efficient American vehicles that will improve our environment and strengthen our economy," EPA administrator Lisa P. Jackson said.
U.S. Transportation Secretary Ray LaHood calls the proposals a "win-win-win for the environment, businesses and the American consumer" due to a reduction in transportation's environmental impact as well as a reduction in the cost of transporting freight.
These proposals, the firsts of their kind, will be phased in starting in 2014 if approved.
The government says the new standards will reduce GHG emissions by nearly 250 million metric tons and save 500 million barrels of oil within the first five years.
