New Vehicle Fuel Efficiency Standards Would Cut Carbon Pollution
New fuel economy standards proposed June 19 for “medium and heavy-duty” vehicles in
model years 2021 to 2027 would lower CO2 emissions by some 1 billion metric tons, cut fuel costs by about $170 billion and reduce fuel consumption by up to 1.8 billion barrels, according to the Environmental Protection Agency (EPA).
EPA added that those reductions nearly match total greenhouse gas emissions associated with energy use by all U.S. residences in one year, and that the anticipated oil savings exceed a year’s worth of U.S. imports from the Organization of Petroleum Exporting Countries.
The regulations apply to semi-trucks, large pickup trucks and vans and all types and sizes of buses and work vehicles. And while such vehicles account for only about 5 percent of vehicles on the road, they produce about 20 percent of GHG emissions and oil use in the U.S. transportation sector.
The new regulations also include separate engine standards that will promote continued progress on engine efficiency and allow for direct measurement of engine emissions.
The standards will become final after a 60-day public comment period.
