"Federal highway officials say the proposed regulation would bring clearer data, but critics say it’s an example of federal overreach".
"The Department of Transportation on Thursday proposed a new requirement that states and metropolitan areas measure the amount of carbon dioxide being released through driving on interstate highways and other major roads.
The proposed rule would obligate state and local officials to set targets to reduce emissions in the coming years, using 2021 as the baseline. It would add emissions to an existing list of performance measures — originating from transportation bills in 2012 and 2015 — that includes data on safety, congestion, pavement and other items.
Transportation is the top U.S. source of greenhouse gas emissions, and federal highway officials under President Biden say the proposed regulation is meant to bring clearer data, increased transparency and better decisions at all levels of government and among the driving public. The rule is intended to track and reduce tailpipe emissions that spur climate change."
