The new requirements affect a class of vehicles that includes school buses, large pickups, delivery and passenger vans, garbage trucks and long-haul tractor-trailers. These heavy- and medium-duty vehicles represent only about 5 percent of total highway traffic but account for 20 percent of transportation-related fuel consumption and carbon emissions. Administration officials said they expect that when the new standards are fully implemented in coming years, they will cut more than 1 billion tons of carbon pollution from the atmosphere, save nearly $170bn in fuel costs and reduce oil consumption by an estimated 84 billion gallons.
“The standards promote a new generation of cleaner, more fuel-efficient trucks by encouraging the development and employment of new and advanced cost-effective technologies through model year 2027,” said Gina McCarthy, administrator of the Environmental Protection Agency, which developed the new rules in conjunction with the National Highway Traffic& Safety Administration. “These standards are ambitious and achievable, and they will help ensure the American trucking industry continues to drive our economy — and at the same time protect our planet.”
