President Donald Trump is expected to unveil a proposal on Wednesday in Washington to weaken federal vehicle fuel-economy requirements through the 2031 model year, loosening regulatory pressure on automakers to limit gasoline-powered tailpipe pollution. The outline — disclosed to reporters by people familiar with White House plans who spoke on condition of anonymity — would lower targets that determine how far new cars and light trucks must travel on a gallon of gasoline. The move follows a series of Trump administration actions since January that have already relaxed tailpipe rules, ended fines for failing to meet mileage standards and rescinded certain electric vehicle incentives. The White House frames the change as expanding consumer choice and affordability for gasoline vehicles.
Key Takeaways
- The proposal, announced at a White House event expected to include CEOs from the three largest U.S. automakers, would cut fuel-economy mandates through the 2031 model year, according to a White House official and people briefed on the plan.
- Under the Biden plan, passenger cars were required to average about 50 miles (81 kilometers) per gallon by 2031; current averages are roughly 39 miles (63 kilometers) per gallon today.
- EVs made up about 8% of new U.S. vehicle sales in 2024, per Cox Automotive; no federal policy currently forces automakers to sell EVs nationwide.
- Industry leaders such as Ford and Stellantis publicly praised the planned rollback as aligning standards with market realities, while environmental groups warned it will increase greenhouse-gas emissions and slow EV adoption.
- Transportation Secretary Sean Duffy has urged reversing Corporate Average Fuel Economy (CAFE) rules and argued that prior standards improperly counted EVs in fuel-economy calculations.
- The administration has already repealed fines for noncompliance and removed a consumer tax-credit framework of up to $7,500 for some EV purchases, signaling a broader reshaping of federal incentives for cleaner vehicles.
Background
Fuel-economy rules in the United States date back to the 1970s oil shocks and have been periodically tightened to improve energy security and cut pollution. The Biden administration set a more aggressive trajectory that sought roughly a 50 mpg passenger-car fleet average by model year 2031 and annual percentage increases in efficiency for light-duty vehicles and light trucks in late-2020s model years. Those standards also included stringent tailpipe rules designed to accelerate electric-vehicle adoption by making gasoline vehicles relatively less economical.
The auto industry has long argued that rapid changes in standards create compliance cost and market risk, especially given consumer preferences, product mix and the still-limited market share of EVs. Automakers say state rules, supply-chain constraints for batteries and uneven charging infrastructure complicate swift transitions. States such as California have pursued zero-emission vehicle mandates for new-sales timelines independent of federal policy, creating a patchwork that manufacturers must navigate. Political control of federal agencies and Congress has produced sharp swings in policy direction in recent years.
Main Event
According to people briefed on the plans, the White House will propose reducing the fuel-economy requirements that govern how far a new vehicle must travel on a gallon of gasoline through model year 2031. The outline was not released publicly ahead of the announcement and specific numeric targets for the rollback were not immediately available from officials. The decision will be announced at a White House event expected to include top executives from the three largest U.S. automakers, who have publicly welcomed the change.
The administration argues the rollback will broaden consumer access to a wider range of gasoline-powered vehicles and lower costs for buyers who are not prepared to adopt EVs. Transportation Secretary Sean Duffy has pressed his agency to reverse existing CAFE rules, contending that previous standards inappropriately factored electric vehicles into compliance calculations. The Biden-era framework applied incremental percentage increases through the late 2020s and sought stronger tailpipe rules to push manufacturers toward electrification.
Industry reaction has been largely positive from major manufacturers: Ford’s chief executive described the rollback as a sensible alignment with market realities, and Stellantis executives signaled support for a realignment of standards. Environmental and climate advocates reacted sharply, saying the change will increase oil consumption, raise greenhouse-gas emissions and place U.S. automakers at a disadvantage in the global green-technology competition. Legal and regulatory challenges are likely to follow; past changes to CAFE and tailpipe rules have drawn litigation and state responses.
Analysis & Implications
Reducing federal fuel-economy requirements would have immediate regulatory and market effects because CAFE targets shape vehicle design, electrification roadmaps and R&D investments. Automakers factor long-term standards into product planning and capital allocation; a rollback could delay or scale back EV programs that were justified under stricter mandates. Conversely, loosening standards may lower near-term compliance costs for manufacturers and reduce penalties they might otherwise face for missing targets.
For consumers, the change is a mixed prospect. In the short term it could preserve more gasoline vehicle choices and potentially reduce sticker prices for some segments, but it may also slow improvements in fuel efficiency that lower operating costs over a vehicle’s life. From a climate standpoint, weaker standards are likely to increase cumulative CO2 emissions from the transportation sector relative to the Biden trajectory, all else equal. That shift would complicate U.S. efforts to meet mid-century climate commitments and could invite countervailing action by states or foreign partners seeking stricter standards.
Geopolitically and economically, the policy tilt has implications for the global EV race. Advocates warn that the U.S. risks ceding leadership in battery technology and EV manufacturing to rivals if federal policy no longer incentivizes a rapid transition. Automakers and suppliers, however, may welcome a smoother, market-driven pace that reduces stranded-asset risk in conventional powertrain factories. The ultimate outcome will depend on detailed rule language, the timeline for implementation and potential state-level responses.
Comparison & Data
| Measure | Biden-era target (2031) | Approx. today (2024) |
|---|---|---|
| Passenger-car fleet average (mpg) | ~50 mpg (81 km/gal) | ~39 mpg (63 km/gal) |
| EV share of new sales (U.S.) | Policy goal: 50% of new sales by 2030 (Biden target) | ~8% (2024, Cox Automotive) |
The table shows the gap between current fleet averages and Biden-era targets, and the large distance between current EV market share and the administration’s 2030 ambition. That disparity helps explain industry complaints about the feasibility and cost of rapid regulatory tightening. Any rollback narrows the regulatory gap in the near term but increases reliance on market signals, consumer demand and state policies to drive electrification.
Reactions & Quotes
Auto executives signaled approval ahead of the White House announcement, framing the change as responsive to market conditions and consumer choice. Their statements emphasize manufacturing practicality and cost considerations as reasons for supporting the rollback.
“This is a win for customers and common sense,”
Jim Farley, Ford CEO (statement)
Ford’s remark reflects the industry’s position that looser standards align policy with present consumer preferences and supply realities. Executives argue that tempered timelines allow continued investment in both internal-combustion and electric powertrains without imposing disproportionate near-term costs.
“We appreciate actions to realign standards with market realities,”
Antonio Filosa, Stellantis CEO (statement)
Stellantis’ statement echoes a broader industry narrative about flexibility for product planning. Automakers contend that a one-size-fits-all federal standard can be disruptive given regional market differences and differing state mandates.
“In one stroke Trump is worsening three of our nation’s most vexing problems: the thirst for oil, high gas pump costs and global warming,”
Dan Becker, Center for Biological Diversity (advocacy)
Environmental groups counter that the rollback will increase oil consumption and greenhouse-gas emissions and undermine competitiveness in green technologies. They have signaled a readiness to pursue legal and political avenues to resist the changes.
Unconfirmed
- The exact numeric fuel-economy targets and annual percentage reductions proposed in the White House outline were not available at the time of reporting.
- It is not yet confirmed which specific compliance mechanisms or credit structures the administration will include, or how the new rule will treat EVs in calculations.
- The scope and terms of any voluntary commitments by automakers at the announcement event are unconfirmed and may be clarified only after formal filings or press releases.
Bottom Line
The proposed rollback represents a significant policy reversal that will reshape regulatory incentives for vehicle manufacturers and buyers in the U.S. In the near term, it reduces pressure on automakers to accelerate electrification and could preserve broader gasoline-vehicle choice and lower immediate compliance costs. However, the change also increases projected greenhouse-gas emissions relative to the prior trajectory and could slow U.S. momentum in EV technology and supply-chain investment.
How the adjustment plays out will hinge on final rule text, legal challenges, state responses and market dynamics such as fuel prices and consumer demand for EVs. Stakeholders from industry, environmental groups and state governments are likely to contest or adapt to the change, making the transport and climate policy landscape volatile in the months ahead.
