Federal Transit Administration Administrator Marc Molinaro yesterday announced the agency finalized guidance for the Capital Investment Grants (CIG) program, which included eliminating calculations for a "social cost of carbon" criteria that had been required under the Biden administration.
FTA will revert to a previously used methodology that relies on the U.S. Environmental Protection Agency’s National Ambient Air Quality Standards designation, based on the city in which a transit project is located, FTA officials said in a press release.
The updated guidance also incorporates other feedback received in response to the August 2025 Proposed Policy Guidance public comment period. Among the 16 respondents providing comments were transit agencies, interest groups, policy organizations and individuals, FTA officials said.
FTA applied the updated guidance to rate projects for the CIG program’s FY2026 annual report, which is available here.
