Trump Scraps Biden's Fuel Economy Rules, Sparks Climate Fears
Trump Rolls Back Biden's Car Mileage Standards

In a move that has ignited a fierce debate over climate policy and consumer costs, President Donald Trump announced on Wednesday a significant rollback of the fuel-economy standards established under his predecessor, Joe Biden. The President framed the decision as a necessary step to make new cars more affordable for Americans.

Automaker Support and Environmental Backlash

Flanked by the CEOs of Ford and Stellantis, along with a senior official from General Motors, Trump signaled strong backing from the nation's largest automakers. The President declared his administration was taking "historic action to lower costs for American consumers, protect American auto jobs and make buying a car much more affordable." Ford's CEO, Jim Farley, echoed this sentiment, calling the announcement a victory for common sense.

However, environmental advocates reacted with immediate and sharp criticism. They argued this policy reversal, part of a series of anti-environmental actions by Trump, would have a disproportionately large impact due to America's reliance on automobiles. Dan Becker of the Center for Biological Diversity labeled the move as Trump "taking a wrecking ball to the biggest single step any nation has ever taken to combat oil use, global warming pollution, and helping save consumers money at the gas pump."

The Battle Over CAFE Standards and EVs

The policy at the centre of the controversy is the Corporate Average Fuel Economy (CAFE) standards. First introduced in 1975, these rules mandate that vehicles achieve the "maximum feasible" fuel efficiency. The Biden administration had recently strengthened these targets, aiming for an average of more than 50 miles per gallon by 2031.

The Trump administration, however, contends that the revised standards were improperly calculated, unfairly factoring in electric and hybrid vehicles and making the goals unattainable for traditional gasoline-powered cars. This argument is part of Trump's broader fight against what he terms an electric vehicle (EV) "mandate," a stance that has even created tension with Tesla CEO Elon Musk.

Throughout 2025, major US automakers like GM have already scaled back or delayed plans for new EV production capacity. While this shift saves companies billions in investment, analysts question whether those savings will be passed on to consumers. Charlie Chesbrough of Cox Automotive noted that while meeting high standards adds to vehicle cost, consumer demand for fuel efficiency remains strong, with hybrid sales rising significantly.

Potential Consequences for Climate and Industry

Critics warn the rollback will have severe long-term consequences. Gina McCarthy, a former senior official under Presidents Biden and Obama, stated the decision would harm the US auto industry by slowing its transition to cleaner technologies and exacerbate climate change. "The rest of the world will continue to innovate and create cleaner cars that people want to buy and drive, while we're forced to sit in our clunkers, paying more for gas, and pumping out more tailpipe emissions," she argued.

The full details of the regulatory rollback were not immediately released. The announcement follows other actions by Congressional Republicans, including repealing clean-energy tax credits and challenging California's authority to set its own vehicle emission limits. The debate now centres on whether the promised short-term savings on car stickers will outweigh the long-term environmental and economic costs of increased fuel consumption and pollution.
