WASHINGTON (September 28, 2026)—Earlier today, the federal government under President Donald Trump finalized a rollback of fuel economy standards for passenger cars and trucks. By doing so, the administration effectively eliminated the nation’s Corporate Average Fuel Economy (CAFE) standards, which have improved vehicle efficiency and saved families about $321 billion at the gas pump since the modern CAFE program was implemented in 2010.
Below is a statement by Dr. Dave Cooke, senior vehicles analyst for the Union of Concerned Scientist’s (UCS) Clean Transportation Program.
“The federal government’s decision to gut fuel economy standards is a handout to automakers and oil companies that will strap American consumers already struggling with an affordability crisis. According to UCS analysis, CAFE standards have saved consumers over $32 billion since the Iran War began and sent gas prices skyrocketing. Weakening these standards means drivers will spend more on fuel while having fewer options to choose efficient vehicles.
“The administration claims this rollback will save consumers money, but even the government’s own analysis shows the opposite: consumers will spend more over the lifetime of their vehicles. Any small reduction in upfront vehicle costs will be outweighed by higher fuel expenses.
“This rollback doesn't just stall progress—it moves the nation backward. For example, the administration’s 2031 standards are weaker than what the new vehicle fleet had already achieved in 2024. This industry giveaway is a raw deal for drivers, who deserve vehicles that cost less to operate and give them more choices—not a policy that forces them to spend more at the pump.”
