WASHINGTON (Bloomberg) -- President Barack Obama directed his administration to issue the next round of fuel efficiency and greenhouse gas standards for medium- and heavy-duty vehicles by March 2016.
Obama said the action would benefit the economy through lower costs for consumers and development of new technology while also enhancing U.S. energy security.
The standards also would impose tougher fuel economy standards on heavy-duty pickup trucks and vans. They would build upon rules that went into effect in model year 2013, setting a fleetwide average for each manufacturer of heavy-duty vehicles based on the average carrying and towing capacity of that manufacturer’s vehicles.
The higher mileage standards are part of Obama's strategy for energy security and dealing with climate change, the White House said in a statement. The administration previously set a standard requiring automakers to double average fuel economy of their fleets to 54.5 miles per gallon by 2025.
As part of today's action, the EPA and the Department of Transportation's National Highway Traffic Safety Administration are being directed to to issue a Notice of Proposed Rulemaking by March of next year.
Heavy-duty vehicles account for about a quarter of U.S. on-road fuel use and greenhouse gas emissions from transportation, according to the administration.
Industry groups were generally supportive of the new standards and the collaboration between the government and manufacturers.
The American Trucking Association urged the government to proceed cautiously. ATA president Bill Graves said his group supported an earlier round of efficiency standards and "hopes the administration will set forth a path that is both based on the best science and research available and economically achievable."
Today's announcement follows the first-ever fuel-economy rules for U.S. truck makers three years ago, which sought to improve efficiency by about 20 percent by 2018, saving $50 billion in fuel costs over five years and decreasing carbon- dioxide emissions.
The administration's plan, which also covered city buses and garbage trucks, was projected to save 530 million barrels of oil. The first round of regulations was intended to take off-the-shelf technologies already employed on real-world trucks.
The next round of regulations, for the 2018 model year and beyond, is expected to force the industry to deploy technology more aggressively. Besides engine and transmission improvements, trucking firms may have to adopt more aerodynamic trailers, adding skirts at the bottom or tails on the end to reduce wind resistance.
Like the first truck-efficiency rules, the next rules are supposed to be negotiated in close consultation with trucking firms, engine manufacturers, environmental groups and other stakeholders, according to a White House fact sheet. The Environmental Protection Agency and the Transportation Department will consult with California regulators so there's a single national standard, the fact sheet said.
Frances Beinecke, president of the Natural Resources Defense Council, said stricter standards would cut carbon pollution and reduce costs for consumers and truck owners.
"Setting the bar higher for trucks will further encourage innovation in the industry," Beinecke said in a statement. "This is a win-win for the environment and the economy."
