EDITOR BRIEF
The US Department of Transportation finalized a rule weakening fleet fuel economy standards, replacing a Biden-era 50.4 mpg target for model year 2031 with 34.9 mpg. The Trump administration says the rollback will lower average vehicle costs, while consumer, health, and environmental groups strongly oppose the move.
COMMENTARY
The decision marks a major deregulatory shift for the auto industry and could slow automakers’ transition toward more efficient and electric vehicles. It may also intensify legal and political fights over emissions policy as states, environmental groups, and manufacturers navigate conflicting climate and affordability pressures.
