The Trump administration will dramatically relax automobile emissions and fuel economy standards so that only modest efficiency gains are required through 2026, according to people familiar with the matter.
In a rule to be announced as early as March 31, the administration will require automakers to boost the fuel efficiency of new vehicles each year by a 1.5% fleet-average starting in 2021, said three people, who asked not to be identified discussing the measure ahead of its release. The required improvements are far more modest than requirements for an estimated 5% annual gains under rules charted during the Obama administration.
The Environmental Protection Agency and U.S. Department of Transportation in August 2018 proposed capping the standards after 2020 instead of rising to an estimated 50-mpg fleet average midway through this decade. That proposal argued easing mileage standards would reduce vehicle prices and make it easier for consumers to replace older, less-efficient cars with newer, safer vehicles, avoiding thousands of traffic fatalities in the process.
The administration has scaled back those earlier safety estimates as it abandoned the initial plan to freeze the standards and now is requiring modest 1.5% annual improvements instead. Under the new approach, far fewer highway fatalities would be averted than originally projected, according to a draft of the final rule obtained earlier this month by Democratic Senator Tom Carper’s office, which released a summary of its contents to reporters.
Driver safety is paramount for trucking companies, but determining which drivers are most likely to be involved in a crash is no simple task.

“This rule utterly fails to deliver any of its promised benefits of safer, more affordable fuel-efficient cars,” Carper said in a statement after reviewing the draft rule. “It is likely to be overturned by the courts and subject automakers to years of costly litigation and confusion in the process.”
A spokesman for the National Highway Traffic Safety Administration, the Transportation Department agency responsible for the regulation, declined to comment.
EPA and DOT already concluded a major portion of the push last fall when it stripped California of its authority to regulate tailpipe greenhouse gas emissions from automobiles, sparking a flurry of lawsuits by the state and others challenging the move.
The car rule comes as part of a broader Trump administration effort to dial back environmental regulations, including mandates on power plants and oil wells.
Dan Becker, director of the Safe Climate Campaign, said, “[President Donald Trump] is rolling back the biggest single step any nation has taken to fight global warming, cut oil use and save money at the pump. He is rejecting cleaner, efficient cars.”
