Trump says he approved new fuel economy standards ending Biden-era electric vehicle mandate
Environmental organizations have filed a lawsuit against the Trump administration to challenge the relaxation of vehicle fuel economy rules. The plaintiffs argue the decision will increase gas consumption, raise pollution levels, and make vehicles less efficient. This follows a broader legal push against the National Highway Traffic Safety Administration after President Trump approved regulations on September 28 that lowered fuel efficiency targets from 50 to 30 mpg through 2031. The administration maintains these changes help domestic manufacturers and lower vehicle prices.

Environmental groups sue Trump administration over eased fuel economy rules
Environmental organizations have filed a lawsuit against the Trump administration to challenge the relaxation of vehicle fuel economy rules. The plaintiffs argue the decision will increase gas consumption, raise pollution levels, and make vehicles less efficient. This follows a broader legal push against the National Highway Traffic Safety Administration after President Trump approved regulations on September 28 that lowered fuel efficiency targets from 50 to 30 mpg through 2031. The administration maintains these changes help domestic manufacturers and lower vehicle prices.
Why it matters
The dispute centers on the shift away from Biden-era electric vehicle mandates. A coalition of 26 states, cities, and counties previously sued over the reduced Corporate Average Fuel Economy standards. These rules dictate the minimum average fuel efficiency for new passenger cars and light trucks.
What is confirmed
- President Donald Trump approved regulations on September 28 that reduced fuel efficiency targets from 50 to 30 mpg through 2031.
- Michigan Attorney General Dana Nessel joined a coalition of 26 states, cities, and counties suing the National Highway Traffic Safety Administration.

Michigan Joins Multi-State Lawsuit Over Trump Fuel Economy Rollback
Michigan Attorney General Dana Nessel has joined a coalition of 26 states, cities, and counties suing the National Highway Traffic Safety Administration. The lawsuit challenges a final rule that lowers Corporate Average Fuel Economy standards for new passenger cars and light trucks. This legal action follows President Donald Trump's September 28 approval of regulations that reduced fuel efficiency targets from 50 to 30 mpg through 2031. While the administration claims the move lowers vehicle prices and aids domestic manufacturers, opponents argue it increases pollution and long-term fuel costs.
Why it matters
The rollback dismantles a Biden-era electric vehicle mandate to relax pollution controls on gasoline-powered vehicles. Industry analysts suggest these changes may shift investment toward high-profit segments like V-8 engines and pickup trucks. General Motors expects $20.4 billion in savings from the new standards.
What is confirmed
- President Donald Trump approved new fuel economy standards on September 28, 2026.
- The new regulations lower fuel efficiency targets from 50 to 30 mpg through 2031.
- Michigan Attorney General Dana Nessel joined a coalition of 26 states, counties, and cities suing the NHTSA.
- The Trump administration relaxed regulatory requirements for pollution control in gasoline-powered cars and light trucks.

Trump Finalizes Fuel Rules Ending EV Mandate
President Donald Trump approved new Corporate Average Fuel Economy standards on September 28, 2026, dropping fuel efficiency targets from 50 to 30 mpg through 2031. The U.S. Transportation Department finalized the regulations to dismantle Joe Biden's electric vehicle mandate. While the administration asserts the rollback cuts vehicle prices and benefits domestic manufacturers like General Motors—which eyes $20.4 billion in projected savings—critics argue the policy increases emissions and long-term fuel costs. Environmental organizations, alongside a coalition of states, cities, and counties, filed lawsuits on October 2 challenging the administration.
Why it matters
The federal reversal targets vehicle efficiency targets and greenhouse gas standards put in place by the prior administration to accelerate electric vehicle adoption. General Motors projects $20.4 billion in savings as part of broader industry relief totaling $60.6 billion. However, opponents contend the rollback relies on flawed logic regarding technology pricing, mileage, and fuel savings while gas prices soar.
What is confirmed
- President Donald Trump approved new federal fuel economy standards on September 28, 2026, ending a Biden-era electric vehicle mandate.
- The U.S. Transportation Department finalized lower vehicle fuel economy standards extending through 2031.
- General Motors anticipates $20.4 billion in projected savings from the eased rules, contributing to $60.6 billion in potential savings for automakers.
- A group of environmental organizations sued the Trump administration on October 2 over the relaxation of key vehicle fuel economy rules.
- A coalition of cities, states, and counties also challenged the administration's rollback, citing pollution and consumer costs.
Still unconfirmed
- The Trump administration relied on flawed logic and made errors in how it accounted for fuel savings, technology prices, and mileage to justify scrapping vehicle emission rules.
What to watch next
- Judicial rulings on the lawsuits filed by environmental organizations, states, and cities against the Trump administration.
- Further financial disclosures from automakers detailing savings under the eased 30 mpg standards.

NHTSA Finalizes Rollback of Biden-Era Fuel Economy Standards
The National Highway Traffic Safety Administration finalized new Corporate Average Fuel Economy standards for passenger cars and light trucks on September 28, 2026. President Donald Trump approved these regulations to dismantle a Biden-era electric vehicle mandate, claiming the move will lower vehicle prices. While the administration asserts the policy helps domestic manufacturers like Ford, General Motors, and Stellantis, environmental groups have filed lawsuits. These critics argue the rollback will increase harmful emissions and raise fuel costs for consumers.
Why it matters
The Biden administration previously implemented strict mileage rules to accelerate electric vehicle adoption and reduce pollution. This regulatory reversal shifts the focus back to traditional fuel standards. The conflict now moves to the courts as environmentalists challenge the legality and impact of the decision.
What is confirmed
- The National Highway Traffic Safety Administration finalized Corporate Average Fuel Economy standards for passenger cars and light trucks on September 28, 2026.
- President Trump approved new fuel economy standards that roll back Biden-era rules intended to promote electric vehicle adoption.
Still unconfirmed

Major auto manufacturers including General Motors, Ford, and Stellantis were cited by the president as wanting to build vehicles domestically under the new policy framework.

Why it matters

Supporters argue the changes free consumers from unwanted vehicle choices and lower costs, while critics contend that reducing pollution controls carries environmental hazards and disadvantages domestic automakers against international rivals.

Trump Approves New Fuel Standards Ending Biden EV Rules
President Donald Trump announced he signed off on new vehicle fuel economy standards designed to dismantle the previous administration's electric vehicle push. The updated regulations relax requirements for automakers to control pollution and scale back policies intended to spur electric vehicle adoption. Trump defended the policy shift by arguing that the prior rules forced motorists into vehicles they never wanted. Critics warn that relaxing these pollution controls carries a significant environmental cost and risks leaving domestic carmakers at a disadvantage against global competitors.
Why it matters
The changes directly target policies put in place by the Biden administration to accelerate the transition toward electric vehicles. Environmental critics argue that rolling back these efficiency requirements increases pollution. Meanwhile, industry analysts note that slowing down domestic electric vehicle development could hurt carmakers as global sales rapidly expand.
What is confirmed
- President Donald Trump announced he approved new fuel economy standards rolling back Biden-era rules.
- The new fuel economy standards will reverse the Biden administration policies meant to spur electric vehicle adoption.
Still unconfirmed
- US carmakers that delay EV development could be left at a significant disadvantage to foreign rivals in the coming years as EV sales grow rapidly around the world.
