Fleet performance data collected through the Federal Automotive Statistical Tool (FAST) website reveals trends in federal agencies' alternative fuel vehicle (AFV) acquisitions, petroleum reduction efforts, and alternative fuel use. These data can help agencies analyze their fleets' performance in meeting federal mandates.

The Federal Energy Management Program posts federal fleet performance data sets in various formats, including charts and maps, data sets, and annual reports that can be downloaded, saved, and manipulated for individual research.

The methodologies section explains which agencies, vehicles, and fuels are covered and tracked through FAST. For more information about the data, analyses, and trends presented, contact Jesse Bennett at the National Renewable Energy Laboratory (NREL).

EPAct 1992 Alternative Fuel Vehicle Acquisition Requirements Data
Excel file shows AFV requirements, acquisitions, and credits for federal agencies.
Federal Fleet Vehicle Inventories
Excel files detail federal AFVs by fuel type, total domestic federal fleet AFVs by agency and year, and more.
EPAct 2005 Waivered Alternative Fuel Vehicles Data
Excel files detail annual data regarding federal agencies' waivered alternative fuel vehicles under EPAct 2005.
Federal Fleet Fuel Consumption Data
Excel files detail federal fleet fuel consumption, which is measured in gasoline gallon equivalents.


NREL's analysis of federal fleet performance uses data derived from FAST. Certain covered federal departments and agencies are required to report annually on the number of alternative fuel vehicles in their fleets as well as the total number of all vehicles, whether light-, medium-, or heavy-duty. They are also required to specify and quantify the type of fuel used. Total vehicle counts and alternative and petroleum fuel consumption amounts are for domestically based vehicles, including law enforcement and emergency vehicles.

  • Army Corps of Engineers
  • Court Services and Offender Supervision Agency
  • Executive Office of the President
