Trump Administration Weakens Fuel Economy Standards

The Trump administration announced Monday it is rolling back Corporate Average Fuel Economy (CAFE) standards for vehicles, a move the Department of Transportation claims will make cars more affordable and support American manufacturing. The new rule lowers the average fuel economy requirement for vehicles from 50.4 miles per gallon by 2031 to 34.9 miles per gallon by 2031. It also eliminates the previous administration's emphasis on electric vehicle production to meet these requirements.

Transportation Secretary Sean P. Duffy stated the revised guidelines are "commonsense" and will "make the American dream affordable again, putting safer cars on the road, and investing in the American autoworker." The National Highway Traffic Safety Administration (NHTSA) Administrator Jonathan Morrison added that the rule "restores integrity to the national fuel economy program, balancing vehicle affordability and energy conservation goals while improving safety on our roadways."

NHTSA asserts that the relaxed standards could reduce the average cost of new vehicles by as much as $1,300 and save consumers $138 billion over the next five years. The department also anticipates the change will cut U.S. yearly oil consumption by 1.3 billion barrels in 2050. President Donald Trump previously stated on social media that these changes would "take the waste out of building cars in America" and lead to "LOWER PRICES."

CAFE standards, established in 1975, aim to conserve fuel and reduce dependence on foreign oil. Historically, automakers have used electric and hybrid vehicles to meet fleet-wide averages, allowing for the sale of less fuel-efficient models like trucks and SUVs. The Trump administration argued that the prior CAFE standards effectively acted as a mandate for electric vehicle adoption, though NHTSA stated its 2024 rule did not mandate EVs but rather set performance-based standards.

The agency is also modifying the classification of light trucks and passenger vehicles starting in 2030. This reclassification aims to remove incentives for altering designs solely for classification purposes, potentially increasing the availability of lower-cost vehicle options and allowing manufacturers to produce vehicles that consumers desire, such as hatchbacks and smaller footprint cars.

Environmental advocates and climate experts have strongly criticized the decision. Gina McCarthy, former EPA administrator, stated, "Rather than keeping the U.S. at the forefront of innovation and improving affordability, this administration has chosen to do the opposite." The Sierra Club warned that less fuel-efficient vehicles would lead to increased gasoline consumption, higher costs for drivers, and worsening air pollution.

Automakers, however, expressed a more favorable view. The Alliance for Automotive Innovation, a trade group, indicated it was reviewing the rule but acknowledged NHTSA's effort to "better align fuel economy standards with the law and current market conditions." John Bozzella, president and CEO of the alliance, commented that the previous administration's standards were "out of step with market realities and customer demand" and that the current rule is an "appropriate course correction."

The transportation sector is the largest source of greenhouse gas emissions in the U.S., with cars and trucks accounting for over 75% of those emissions, according to the EPA. These gases are the primary driver of climate change.
