Trump says he is rolling back Biden-era US fuel economy rules for cars

United States President Donald Trump has announced new fuel economy standards that roll back requirements adopted under his predecessor, arguing they will lower automobile prices and encourage manufacturers to expand production in the US.

In a social media post on Saturday, Trump said the new standards would “TERMINATE” what he called former US President Joe Biden’s “EV (electric vehicle) mandate”, accusing the previous administration of imposing costly requirements on carmakers and steering consumers towards electric vehicles.

“These new Standards will take the waste out of building cars in America. That means LOWER PRICES, saving families thousands on a new, beautiful, and safe car,” Trump wrote.

The changes form part of a broader Trump administration effort to reverse Biden-era policies supporting lower-emission vehicles, increasing the gap between US policy and global trends favouring electric vehicles.

While Trump and US Republicans have used the term “EV mandate” to describe higher fuel efficiency requirements instituted under Biden, a Democrat, there are no federal guidelines or laws that require Americans to buy electric cars or bar the sale of ones powered by petrol.

At the centre are Corporate Average Fuel Economy (CAFE) standards. This system, established by the US Congress in 1975, requires automakers to meet average fuel economy targets across all cars and light trucks they sell, meaning that a brand that sells an inefficient vehicle would also have to sell a more efficient one to help comply with the government’s standards.

Under rules finalised by the Biden administration in 2024, the required fleetwide fuel economy was scheduled to rise from 39.1 miles per gallon (mpg) to about 50.4mpg by 2031. The administration said then the measures would reduce fuel consumption and emissions to combat climate change while helping motorists save money at the pump.

As a result, auto manufacturers have ramped up production of EVs to help meet the Biden-imposed fuel economy requirements. The Republican-controlled US Congress, however, gutted consumer tax incentives last year for electric vehicles as part of Trump’s One Big Beautiful Bill Act.

Trump did not provide details regarding what the new fuel economy standards would be. But in December 2025, he announced a proposal that would set the industry fleetwide average for light-duty vehicles at roughly 34.5mpg by 2031, more than 30 percent lower than the Biden-era rule.

In a reposting of Trump’s announcement, US Transportation Secretary Sean Duffy said an announcement would be “COMING MONDAY”.

美国总统表示，他将终止所谓的“电动汽车强制令”，该强制令旨在引导消费者购买电动汽车。

美国总统唐纳德·特朗普宣布了新的燃油经济性标准，推翻了其前任制定的相关要求。他认为，这些新标准将降低汽车价格，并鼓励制造商扩大在美国的生产规模。

特朗普周六在社交媒体上发帖称，新标准将“终止”他所谓的美国前总统乔·拜登的“电动汽车强制令”，并指责前任政府对汽车制造商施加了代价高昂的要求，引导消费者转向电动汽车。

美国交通部称拜登燃油经济性规则超出法律授权范围（共3条，此为第3条）。

特朗普写道：“这些新标准将消除美国汽车制造过程中的浪费。这意味着更低的价格，让每个家庭都能省下数千美元，买到一辆崭新、漂亮、安全的汽车。”

这些变化是特朗普政府为推翻拜登时代支持低排放汽车的政策而采取的更广泛举措的一部分，进一步拉大了美国政策与全球电动汽车发展趋势之间的差距。

虽然特朗普和美国共和党人使用“电动汽车强制令”一词来描述民主党人拜登执政期间实施的更高燃油效率要求，但目前没有任何联邦指导方针或法律要求美国人购买电动汽车或禁止销售汽油动力汽车。

核心是企业平均燃油经济性（CAFE）标准。该体系由美国国会于1975年制定，要求汽车制造商在其销售的所有轿车和轻型卡车上达到平均燃油经济性目标。这意味着，如果一个品牌销售的车辆燃油效率低下，那么它也必须销售燃油效率更高的车辆，以帮助其符合政府的标准。

根据拜登政府在 2024 年最终确定的规则，车队整体燃油经济性要求将从每加仑 39.1 英里（mpg）提高到 2031 年的约 50.4mpg。当时，政府表示，这些措施将减少燃油消耗和排放，以应对气候变化，同时帮助驾车者节省加油费用。

因此，汽车制造商纷纷提高电动汽车的产量，以满足拜登政府提出的燃油经济性要求。然而，由共和党控制的美国国会去年通过了特朗普的“一项宏伟法案”（One Big Beautiful Bill Act），大幅削减了电动汽车的消费者税收优惠。

特朗普没有提供关于新燃油经济性标准的具体细节。但在2025年12月，他宣布了一项提案，该提案拟将2031年轻型车辆的行业平均燃油经济性设定在每加仑34.5英里左右，比拜登时代的规定低30%以上。

美国交通部长肖恩·达菲转发了特朗普的声明，并表示将于“下周一”发布公告。
