WASHINGTON — Future tractor-trailers, school buses, delivery vans, garbage trucks, and heavy-duty pickup trucks would have to use less energy under fuel-efficiency rules proposed by the Obama administration — the first ever for such vehicles.
The Environmental Protection Agency and the Transportation Department are moving ahead with a proposal for medium- and heavy-duty trucks, beginning with those sold in the 2014 model year and into the 2018 model year.
The plan is expected to call for about a 20 percent reduction in greenhouse gas emissions and fuel consumption for long-haul trucks, said people familiar with the plan. They spoke on condition of anonymity because they did not want to speak publicly before the official announcement, expected today.
Overall, the proposal is expected to seek reductions of 10 to 20 percent in fuel consumption and emissions, depending on vehicle size. Large tractor-trailers tend to be driven up to 150,000 miles a year, making them candidates for improved mileage.
