Feds Finalize Future Car Mileage Standards

The federal government issued final regulations implementing an agreement reached with auto industry representatives and California regulators on fuel economy and carbon dioxide (CO2) emissions limits for model-year ’17–’25 vehicles. The fleetwide average will rise from 34.5 mpg at the end of 2016 to 54.5 mpg for model-year 2025—a nearly 5% annual increase with slightly lower standards for light-duty trucks. 

The agreement preserves California’s authority to regulate CO2 emissions and other greenhouse gases while creating a single national standard. CO2 emissions and fuel economy are linked since carbon dioxide is a byproduct of fossil-fuel combustion. The automakers pursued an agreement to increase fuel economy, which would also preserve affordability, vehicle choice, jobs and safety.
