Under the Energy Policy Act of 1992 (EPAct) and subsequent regulations, certain vehicle fleets operated by state agencies or alternative fuel providers are required to acquire alternative fuel vehicles (AFVs) as a fraction of their light-duty vehicle acquisitions. If a fleet has explored available options and cannot meet the requirements, it may request exemptions. This chart shows the number of vehicles exempted by model year. The number of exemptions dropped significantly during the years following the economic recession of 2008, likely because of two factors. First, the economic downturn led to fewer vehicle acquisitions, which in turn reduced the AFV-acquisition requirement for covered fleets, so fewer exemptions were needed. Secondly, the program offers a number of means to comply, so exemptions are mostly unnecessary. In more recent years, the number of fleets requesting exemptions has remained relatively low while the number of vehicles exempted has started to climb as fleets adjust to the changing AFV market (i.e., fewer flexible fuel vehicles and increasing number of electric vehicle models).
