Washington — The Trump administration is moving forward with a plan to roll back stringent gas-mileage rules enacted by the Obama administration. 

The administration has submitted its final version of its plan to the White House Office of Management and Budget for a final review. Details have not been made public yet, but it is expected to call for reducing the required annual fleetwide average mpg increases for carmakers for model years 2021-2026 from the original 5% to a less stringent 1.5%

An earlier portion of the plan that called for revoking California’s right to set higher car emissions rules than the federal government currently mandates was put forth by the Trump administration last September.
