The 2012 transportation law (MAP-21) required transportation agencies to begin using a new system of performance measures to govern how federal dollars are spent and hold them accountable for making progress on important goals, like congestion, traffic fatalities, reliability, road/bridge condition, mode share and carbon emissions. For two years, USDOT worked to establish this new system, soliciting reams of public feedback, and finalizing the measures in January of this year.
Climate impacts aside, tracking carbon emissions is one of the best ways to judge how efficiently we’re moving people and goods. More on that in a minute.
The Trump Administration is attempting to repeal this carbon emissions measure. Take action and provide an official comment to USDOT in support of keeping it intact. (Official notice here)
