As Gas Prices Remain High Due to Illegal War in Iran, Senator Markey Slams Trump for Rollback of Fuel Economy Standards That Save Money, Lower Emissions

Washington (September 28, 2026) - Senator Edward J. Markey, a senior member of the Environment and Public Works Committee, today released the following statement after President Donald Trump announced new Corporate Average Fuel Economy (CAFE) standards, under which automakers will only have to achieve an average fleetwide fuel economy standard of 34.5 miles per gallon by 2031. This is more than thirty percent lower than the previous standards, which required manufacturers to achieve an average fleetwide fuel economy of 50.4 miles per gallon by 2031-a standard that would have continued to save drivers money, given drivers more fuel-efficient choices at the dealership, and cut our national dependence on globally priced oil.

"Strong fuel economy standards mean that Americans spend less at the gas pump, our country imports less foreign oil, drivers can choose better options at the dealership, and we are better protected from pollution, price spikes, and climate change," said Senator Markey. "Trump's economic and foreign policy crises are already leaving families underwater from rising gas prices-and by attacking fuel economy standards, he's also setting fire to the lifeboat."

Senator Markey has been a fuel economy champion since standards were enabled by the Energy Independence and Security Act of 2007, which included fuel economy language co-authored by then-Rep. Markey. That law included Markey's language that said the standard must be at least 35 mpg by 2020, and that the "maximum feasible standard" must be set every year.

In June, Senator Markey introduced the Gas Money Saved Act, legislation that would require the Department of Transportation (DOT) to examine whether it can strengthen CAFE standards during periods of skyrocketing gas prices. The legislation would also reinstate the penalties for automakers that fail to produce fuel-efficient vehicles as options for American drivers, which were removed as part of the giveaways to corporations and the super-rich in the Republicans' Big Ugly Bill in 2025. In February, Senator Markey and Congresswoman Doris Matsui (CA-07) led 78 lawmakers in a letter to the Administration calling on it to withdraw its proposed rollback of fuel economy standards.
