In a significant shift for the automotive industry, the US government has finalized a rollback of vehicle fuel economy standards. This decision reverses the previous administration’s push for more fuel-efficient vehicles, potentially boosting sales of traditional gas-powered cars and trucks.
The Alliance for Automotive Innovation has praised the rollback as an “appropriate course correction” that aligns with market demands and legal requirements, according to Automotive News. However, environmental advocates argue that such measures benefit automakers while leaving consumers to face higher fuel costs, exacerbated by geopolitical tensions such as the ongoing conflict in Iran.
Reuters reports that the Transportation Department has set a new fleetwide average of 34.9 miles per gallon (14.7 km per liter) by 2031, a reduction from the 50.4 miles per gallon (21.4 km per liter) target established by the previous administration. In contrast, the Biden administration had earlier mandated a yearly increase in fuel efficiency for cars, aiming for an 8% rise for model years 2024 and 2025, a 10% increase for 2026, and a 2% annual improvement from 2027 to 2031.
Critics warn that the revised standards could lead to increased global carbon emissions and hinder the transition to electric vehicles, as well as weaken the US’s competitive stance in the global clean-energy market. American drivers are expected to consume more gasoline, potentially adding billions of tons of greenhouse gases to the atmosphere, thereby setting back international climate objectives.

The policy shift favors the production of larger, less fuel-efficient vehicles, such as trucks and SUVs. It also terminates a credit-trading system by 2028, which had provided financial benefits to electric vehicle manufacturers like Tesla and Rivian. International automakers, including Toyota, Volkswagen, and Hyundai, are now positioned to focus on more profitable gas vehicle sales within the US, while directing their electric vehicle development efforts to other markets.
Financially, the rollback is expected to reduce technology costs by $60.6 billion by 2031, with substantial savings projected for major automakers: Stellantis ($6.6 billion), Ford ($5.8 billion), Toyota ($4.5 billion), and Honda ($4.1 billion), as noted by Automotive News.
Meanwhile, the European Union and China are advancing in the opposite direction with stringent regulatory guidelines. Europe has mandated a complete phase-out of internal combustion engine vehicles by 2035, while China enforces strict fuel consumption standards alongside a New Energy Vehicle mandate, compelling automakers to produce a significant number of electric and hybrid vehicles. These measures have enabled Chinese manufacturers to secure around 60% of the global EV market, further reinforced by regulations that ensure the production of efficient electric vehicles.
While the US focuses on gas consumption, China has implemented laws that emphasize electric car battery efficiency, pushing for lighter and longer-range vehicles. The divergent paths of the US, Europe, and China underscore a global regulatory landscape where over 40 countries have implemented fuel economy or greenhouse gas emission standards, collectively accounting for more than 80% of new passenger vehicle sales. These policies predominantly utilize corporate-average fuel economy or fleet-average greenhouse gas limits, tailored to vehicle attributes rather than a uniform standard across vehicle classes.
