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). For more information, see the Federal Fleet Management website.

Executive Order 13834, issued in May 2018, requires the Secretary of Energy (Secretary), in coordination with the Secretary of Defense, the Administrator of General Services, and the heads of other agencies as appropriate, to review the existing federal vehicle fleet requirements. By September 14, 2018, the Secretary must report to the Chairman of the Council on Environmental Quality and the Director of the Office of Management and Budget with opportunities to optimize federal fleet performance, reduce associated costs, and streamline reporting and compliance requirements.
