President Donald Trump is poised to roll back ambitious Obama-era vehicle mileage standards and raise the ceiling on damaging fossil fuel emissions for years to come, gutting one of the United States' biggest efforts against climate change.
The Trump administration is expected to release a final rule Tuesday on mileage standards through 2026. The change making good on the rollback after two years of Trump threatening and fighting states and a faction of automakers that opposed the move waters down a tough Obama mileage standard that would have encouraged automakers to ramp up production of electric vehicles and more fuel-efficient gas and diesel vehicles.
