Diesel Emissions Reduction Act (DERA) Program

The U.S. Environmental Protection Agency established the DERA Program to reduce pollution emitted from diesel engines through the implementation of varied control strategies and the involvement of national, state, local, and tribal partners. DERA includes programs for existing diesel fleets, regulations for clean diesel engines and fuels, and regional collaborations and partnerships. For information on available grants and funding opportunities, see the DERA Funding website.
