State and Alternative Fuel Provider Fleets

The Energy Policy Act (EPAct) of 1992 requires certain state government and alternative fuel provider fleets to acquire a percentage of alternative fuel vehicles (AFVs) each year. Fleets can earn credits for biodiesel use and for AFVs acquired beyond their requirements. These credits can be traded or sold to other fleets to help them meet their requirements. When tracked over time, the dynamics of the EPAct State and Alternative Fuel Provider (S&FP) Rule shows trends that are presented in the following spreadsheets. The Excel files below contain data that you can download, save, and manipulate for individual research. See data for:
