Applicant and/or Project Eligibility Requirements

All states are eligible for this program.

Decarbonization Considerations

This pilot program allows participating states to reduce cost sharing requirements for various decarbonization programs offered by DOT, shifting up to 100% of project costs to the federal government.

Equity Considerations

This pilot program could encourage less-resourced states to participate in DOT decarbonization programs, not just those that can afford cost matches. Based on the programs referenced, US territories and Tribal governments may be eligible to apply, but that should be confirmed with the administrators and/or Secretary prior to proceeding.
