Key Takeaways
- President Donald Trump's administration finalized plans to weaken fuel efficiency standards for cars and trucks.
- The new rules require fleet average fuel economy to reach 34.9 miles per gallon by 2024, down from the previous target of 50.4 miles per gallon.
- Consumer advocacy groups and environmentalists are critical of the move, citing potential health and environmental impacts.
President Donald Trump's administration has finalized plans to weaken fuel efficiency standards for cars and trucks, according to a statement issued on December 3rd, 2025, in the Oval Office at the White House in Washington, DC.
The new regulations, described by the US Department of Transportation as 'among the largest deregulatory actions under the second Trump Administration,' significantly reduce the fleet average fuel economy requirement from 50.4 miles per gallon by model year 2031 to 34.9 miles per gallon by 2024.
This rollback is seen as a major step back from the more stringent standards proposed by the Biden administration, which aimed to improve fuel efficiency and reduce emissions, potentially saving the environment and public health.
Consumer advocacy, health, and environmental groups have expressed strong disapproval of the new rules, arguing that they could lead to higher pollution levels and increased health risks for the public.
The Trump administration justifies the rollback by stating that it would reduce the average cost of a new vehicle by $1,300, citing economic benefits for consumers.
However, critics argue that the long-term costs of increased pollution and health issues could far outweigh the short-term savings, making the move a contentious one in the ongoing debate over environmental policy.
Environmentalists and public health experts warn that the rollback could exacerbate air pollution, leading to higher rates of respiratory illnesses and other health problems, particularly in urban areas.
The decision to weaken fuel efficiency standards is part of a broader effort by the Trump administration to deregulate and reduce government oversight in various sectors, including transportation and environmental protection.
