Alternative Fuel Vehicles (AFVs) & Technology
GSA Fleet assists federal customers in acquiring vehicles that help to meet federal sustainability requirements and reduce costs.
Federal agencies are required to:
- Purchase alternative fuel vehicles (AFVs);
- Acquire all light-duty vehicles as low greenhouse gas vehicles;
- Optimize fleet size;
- Reduce GHG emissions;
- Increase zero emission vehicles or plug-in hybrid acquisitions; and to
- Properly account for and report fleet data.
Federal fleets are required to obtain 75 percent of their light-duty annual acquisitions as AFVs in Metropolitan Statistical Areas (MSAs). Vehicles acquired outside of the MSAs also count toward an agency’s percentage, but are not required. Section 301 of EPACT defines alternative fuels as:
- Denatured alcohol;
- Mixtures containing up to 85 percent methanol or denatured ethanol;
- Natural gas; and
- Propane (liquefied petroleum gas).
In addition, the National Defense Authorization Act of 2008 expanded the definition of an alternative fuel vehicle to include:
- Any vehicle achieving a significant reduction in petroleum consumption;
- Advanced lean burn technology vehicles;
- Fuel cell vehicles; and
- Hybrid electric vehicles.
