"More than 175 environmental organizations sent a letter Tuesday to Transportation Secretary Pete Buttigieg urging him to adopt a federal rule that requires state and city transportation departments to measure and set standards for their greenhouse gas emissions.
The letter, signed by national groups such as Sierra Club, U.S. Public Interest Research Group and Transportation for America, thanked the Biden administration for taking the first step toward implementation of the emission rule but urged them to adopt it as quickly as possible.
“The transportation sector is the largest contributor to greenhouse gas emissions in the United States,” the letter reads. “The addition of the greenhouse gas measure to the Department’s existing performance measurement framework will shine needed light on the climate impacts of these investments and lead to more informed decision-making.”"
