Alternative Fuels
EPA promotes and expands the use of environmentally beneficial alternative fuels and vehicles by providing the states with tools, such as benefits models, State Implementation Plan Credits, and the Clean Fuels Fleet program. EPA also coordinates with the Department of Energy and Department of Transportation so that their Energy Policy Act and Transportation Equity Act of the 21st Century programs promote alternative fuels and vehicles having the greatest environmental gains.
