Fleet Performance Data

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

The Federal Energy Management Program (FEMP) posts Federal fleet performance data sets in various formats, including annual reports, reference graphics, and data files that can be downloaded, saved, and manipulated for individual research. Data sets are organized into the following topics:

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

Federal Fleet Fuel Consumption Data

Fuel consumption is measured in gasoline gallon equivalents (GGE). One GGE contains the same amount of energy as a gallon of gasoline regardless of the actual volume (or density) of fuel.

Methodologies

Data used for NREL's analysis of the Federal fleet are 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.

The Federal agencies required to report this information include:

  • Army Corps of Engineers
  • Court Services and Offender Supervision Agency
  • Department of Agriculture
  • Department of Commerce
  • Department of Defense (including Army, Air Force, Navy, U.S. Marine Corps, and Defense Agencies)
  • Department of Education
  • Department of Energy
  • Department of Health and Human Services
  • Department of Homeland Security (since 2003)
  • Department of Housing and Urban Development
  • Department of the Interior
  • Department of Justice
  • Department of Labor
  • Department of State
  • Department of Transportation
  • Department of the Treasury
  • Department of Veterans Affairs
  • Environmental Protection Agency
  • General Services Administration
  • National Archives and Records Administration
  • National Aeronautics and Space Administration
  • National Science Foundation
  • Nuclear Regulatory Commission
  • Office of Personnel Management
  • Smithsonian Institution
  • Social Security Administration
  • Tennessee Valley Authority
  • United States Postal Service

Total vehicle counts are for domestically based vehicles and include law enforcement vehicles and emergency vehicles. Total alternative fuel and total petroleum fuel also includes fuel used by domestically based vehicles, including law enforcement vehicles and emergency vehicles.
