Alternative Fuel Vehicles

As required by Section 142 of the Energy Independence and Security Act (EISA) of 2007 (Public Law [PL] 110-140), the Department of State (DOS) Fleet Management and Operations (FMO) office has a comprehensive strategy to comply with the current regulatory requirements for reducing vehicular petroleum consumption by two percent per year and for increasing alternative fuel (AF) use in vehicles by ten percent compounded annually as compared to the fiscal year 2005 baseline. The vehicular fuel use requirements are mandated in Executive Order (EO) 13514, “Federal Leadership in Environmental, Energy, and Economic Performance” of 2009 and in EO 13423, “Strengthening Federal Environmental, Energy, and Transportation Management” of 2007, as well as the Energy Policy Act (EPAct) of 1992 (42 USC 13211-13219) as amended by the Energy Conservation Reauthorization Act of 1998 (PL 105-388), the EPAct of 2005 (PL 109-58), the EISA of 2007 (PL 110-140), and the National Defense Authorization Act for Fiscal Year 2008 (PL 110-181). The strategy includes the use of E85, a fuel blend of 85 percent ethanol and 15 percent gasoline, instead of conventional gasoline fuel, the use of B20, a fuel blend of 20 percent biodiesel and 80 percent diesel, in place of conventional diesel fuel, continued use of compressed natural gas (CNG) in natural gas vehicles, increased use of AFs in alternative fuel vehicles (AFVs), improvements in the operating efficiency of DOS vehicles, working with other agencies and organizations to improve AF availability, and continued acquisition of light duty or medium duty vehicles with higher fuel economy, to include AFVs such as flex-fuel vehicles, hybrid electric vehicles, low greenhouse gas emitting vehicles (LGHGEVs), and plug-in hybrid electric vehicles (PHEVs) when they are commercially available and cost feasible versus comparable non-PHEVs.

Section 13218 of the Energy Policy Act of 1992, 42 USC 13218(b), requires each Federal agency to place its annual fleet AFV compliance report on a publicly available website. More information about the DOS AFV Program is provided in the most recent reports, which are reproduced below. More information about AFs is available at
