Compliance Methods

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. Find guidance documents, tools, and a compliance schedule for state and alternative fuel provider fleets.

Standard Compliance

Standard Compliance requires covered fleets to acquire a percentage of alternative fuel vehicles (AFVs) each year based on the number of light-duty vehicles they acquire. Most established fleets use this method.

Alternative Compliance

Alternative Compliance allows covered fleets to obtain a waiver from Standard Compliance and instead implement petroleum-reduction measures. This method can work well for new fleets and biodiesel fleets.

**How do Standard Compliance and Alternative Compliance methods compare?**
	Standard Compliance primarily through AFV acquisitions	Alternative Compliance through petroleum reduction
Acquire 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
Acquire light-duty AFVs	Each acquisition counted toward a fleet's AFV-acquisition requirements	Credit for alternative fuel use on a gasoline gallon equivalent (GGE) basis
Acquire 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
Implement 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.
Fuel with 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
Invest in alternative fuel infrastructure, alternative fuel non-road equipment, and emerging technologies	Credit based on investment amount	No credit
Reduce vehicle miles traveled (VMT)	No credit	Credit for petroleum reduction in the model year VMT is reduced
Reduce vehicle idling	No credit	Credit toward petroleum reduction
Implement truck stop electrification	No credit	Credit for covered fleet only; no credit for third-party use
