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). Additionally, Executive Order 13423, issued in January 2007, requires federal agencies with 20 vehicles or more in their domestic fleet to increase their alternative fuel use by 10% per year, relative to the previous year, based on a FY 2005 baseline.

Executive Order 13514, issued in October 2009, requires each federal agency to develop, implement, and annually update a Strategic Sustainability Performance Plan. Federal agencies must measure, reduce, and report their greenhouse gas (GHG) emissions, with an overall federal government direct GHG emissions reduction goal of 28% by 2020, relative to a FY 2008 baseline. Federal fleets of 20 vehicles or more must reduce petroleum consumption by a minimum of 2% per year through the end of FY 2020 as compared to 2005 baseline usage. Each agency must establish a comprehensive inventory of GHG emissions for FY 2010, to be updated on an annual basis thereafter. Reductions may be achieved through a variety of measures including the use of AFVs, and fleet optimization efforts.

Additional requirements for federal fleets were included in the Energy Independence and Security Act of 2007, including fleet management plan requirements (Section 142), low 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 2014; Section 142).
