Under the Energy Policy Act of 1992 (EPAct) and subsequent regulations, certain vehicle fleets operated by state agencies or alternative fuel providers are required to acquire alternative fuel vehicles as a fraction of their light-duty vehicle acquisitions. Covered fleets may also meet some of their requirements by using biodiesel blends of 20% (B20) or higher in medium- or heavy-duty vehicles. This chart shows the amount of biodiesel purchased by covered fleets from 2000 to 2023.
