Trump cuts fuel economy standards back to 2014 levels
Summary
Ars Technica reports that the Department of Transportation finalized a rollback of Corporate Average Fuel Economy (CAFE) standards, setting a target of 34.9 mpg by model year 2031, effectively returning to 2014-era levels. The rule tightens the light-truck classification and phases out emissions credits from 2028, with critics arguing it undermines progress on cleaner vehicles and increases costs for consumers.
