The Federal Transit Administration (FTA) issued its finalized guidelines for eliminating the Biden-era “social cost of carbon” criterion for the Capital Investment Grants (CIG) program.

According to an article in Progressive Railroading, “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.”

In a press release from August, the agency called the calculation “overly complex” and said the action is part of USDOT’s effort to “remove unnecessary regulatory requirements and provide the best support possible for locally driven transit projects.”
