Vehicle Acquisition and Fuel Use Requirements for Federal Fleets

Under the Energy Policy Act (EPAct) of 1992, 75% of new light-duty vehicles acquired by covered federal fleets must be alternative fuel vehicles (AFVs). As amended in January 2008, Section 301 of EPAct 1992 defines AFVs to include hybrid electric vehicles, fuel cell vehicles, and advanced lean burn vehicles. Fleets that use fuel blends containing at least 20% biodiesel (B20) may earn credits toward their annual requirements. Federal fleets are also required to use alternative fuels in dual-fuel vehicles unless the U.S. Department of Energy (DOE) determines an agency's vehicle requests qualify for waivers; grounds for a waiver include lack of alternative fuel availability and cost restrictions (per EPAct 2007, section 701).

Additional requirements for federal fleets were included in the Energy Independence and Security Act of 2007, including fleet management plan requirements (Section 142), low greenhouse gas (GHG) emitting vehicle acquisition requirements (Section 141), and renewable fuel infrastructure installation requirements (Section 246). DOE is currently developing a rulemaking on the alternative fuel increase requirements (verified December 2015; Section 142).

Executive Order 13693, issued in March 2015, also requires federal agencies with 20 vehicles or more to improve fleet and vehicle efficiency through the elimination of non-essential vehicles and achieve a 30% reduction of fleet-wide GHGs relative to a fiscal year (FY) 2014 emissions baseline by FY 2025. Covered agencies must also install telematics systems on certain new vehicles; submit annual vehicle acquisition data; ensure that by December 31, 2020, and December 31, 2025, 20% and 50% (respectively) of light-duty vehicle acquisitions are zero emission vehicles (ZEVs) or plug-in hybrid electric vehicles (PHEVs); and plan to install charging and other infrastructure to support new ZEV and PHEV acquisitions.
