A federal proposal for trucks to increase fuel economy and cut carbon emissions would reduce diesel use by 500,000 barrels of oil by 2040, according to a new analysis by the U.S. Department of Energy.
The standards, issued in 2015 by the U.S. Environmental Protection Agency and the National Highway Traffic Safety Administration, take effect in 2021. They get tougher through 2027, according to the聽Energy Information Administration report.
Typical passenger vehicles, which consume 59 percent of the country鈥檚 transportation energy, are not affected.
The new rules would affect heavy-duty pickup trucks, school buses, ambulances, garbage trucks and semi-trucks,聽among others, which account for about 20 percent of U.S. transportation energy use.
The standards require three-quarter- and one-ton pickups to reduce emissions by 2.5 percent per year from 2021 to 2027, according to the report.
Diesel-powered delivery vans, trash trucks, cement trucks, school buses and others would have to reduce by 16 percent. Similar gasoline-powered vehicles have lower reduction rates. And tractor trailers would have to reduce emissions by up to 24 percent compared with 2017.
