Clean Fuel Fleet Program (CFFP)

The CFFP was implemented under the Clean Air Act Amendments of 1990 and applies to fleets in ozone nonattainment areas. The CFFP requires that a percentage of new cars, and light- and medium-duty trucks purchased by certain fleets meet lower hydrocarbon and nitrogen oxide emission standards. Individual states must ensure that appropriate fuels are available for operating these clean-fueled fleet vehicles. (Reference 42 U.S. Code 7586)
