What is a vehicles emission certification standard?
A. Since the mid- 1970’s, the Clean Air Act has required that all vehicles sold in the U.S. meet a federal emissions standard for three pollutants: hydrocarbons, carbon monoxide, and nitrogen oxides. U.S. EPA has been the agency in charge of enforcing the federal emissions certification program. With improved emission control technologies and cleaner fuel, these emission standards have become more stringent over time. The CFFP requires fleets to acquire lower-polluting vehicles certified to emissions standards that are more stringent than the standards in effect for the general vehicle population. Vehicles certified to the CFFP standards are over 70% cleaner than the vehicles certified to the current “base” federal standard.
