Compliance Methods for State and Alternative Fuel Provider Fleets

State and alternative fuel provider fleets that are covered fleets may meet their Energy Policy Act (EPAct) requirements through one of two compliance methods: Standard Compliance or Alternative Compliance.

How do Standard Compliance and Alternative Compliance compare?



Standard Compliance

(Primarily AFV Acquisitions

Alternative Compliance

(Petroleum Reduction)

Light-duty non-AFV electric vehicles ½ credit per non-AFV HEV, non-AFV PHEV, or non-AFV FCEV

¼ credit per neighborhood electric vehicle (NEV) (though not an LDV)
Petroleum reduction from non-AFV electric vehicles
Light-duty AFVs Each acquisition counted toward a fleet's AFV-acquisition requirements Credit for alternative fuel use on gasoline gallon equivalent (GGE) basis
Medium- and heavy-duty AFVs and non-AFV HEVs Credit (one per AFV, ½ per non-AFV HEV) only after requirements are met with light-duty AFV acquisitions Credit for alternative fuel use on a GGE basis
Energy-efficient conventional fuel technologies No AFV credit Petroleum reduction from other fuel-efficient conventional vehicle technologies counts toward petroleum reduction in the model year efficiencies occur.
Biodiesel blends Credit for every 450 gallons of biodiesel in blends of B20 or higher; capped at 50% of annual requirements Credit for biodiesel used in any blend percentage on a GGE basis; no cap on amount of biodiesel used to meet requirements
Investments in alternative fuel infrastructure, alternative fuel non-road equipment, and emerging technology Credit based on investment amount No credit
Vehicle miles traveled (VMT) reduction No credit Credit for petroleum reduction in the model year VMT is reduced
Idle reduction No credit Credit toward petroleum reduction
Truck stop electrification No credit Credit for covered fleet only; no credit for third-party use
