The Department of Transportation and Environmental Protection Agency released final emissions rules Tuesday. 

The agencies will change the Safer Affordable Fuel-Efficient Vehicles Rule setting corporate fuel economy and CO2 emissions standards, known as CAFÉ standards, for model years 2021-2026 passenger cars and light trucks. 

The final rule will increase stringency of CAFE and CO2 emissions standards by 1.5 percent each year through model year 2026, as compared with the standards issued in 2012, which would have required about five percent annual increases. 

EPA Administrator Andrew Wheeler says the final rule “puts in place a sensible national program that strikes the right regulatory balance that protects our environment and sets reasonable targets for the auto industry.” 

Meeting the previous CAFÉ standards were seen as a way to increase biofuel demand. 

Under the SAFE Rule, the projected overall industry average required fuel economy is 40.4 miles per gallon, compared to 46.7 projected requirements for model year 2025 under the 2012 standards.
