Incentives and Laws

The Alternative Fuels and Advanced Vehicles Data Center tracks state-enacted incentives and laws relating to alternative fuel use and reducing petroleum consumption. It also keeps a database of expired incentive and laws enactments for historical purposes. Expired legislation allows users to track engaged policymakers and trends in favored technologies and policy tools over time and to record engaged policymakers. The Excel files below contain data that you can download, save, and manipulate for individual research.
