Trump finalizes rule to make cars less fuel efficient

The US Department of Transportation has finalized plans to weaken fuel efficiency standards, undoing Biden-era regulations that aimed to reach a fleet average of 50.4 miles per gallon by 2031. This move is considered a significant deregulatory action under the Trump Administration. The new rule replaces stricter standards that were set to take effect in 2024, which would have required automakers to increase fuel efficiency every year through 2031. The new rule eliminates the requirement for annual increases in fuel efficiency, effectively allowing cars to become less fuel-efficient. The rule change is expected to increase greenhouse gas emissions and contribute to climate change.
