States no longer have to set targets for highway emissions

The US Federal Highway Administration has removed a rule that required states to set declining carbon dioxide targets for their highway systems. This means state transportation departments and planning organizations no longer have to report on their progress toward reducing emissions from roads.

The US government will no longer track or require states to reduce greenhouse gas emissions from their highway systems. This change removes a key lever for federal oversight of state-level climate action in transportation. It also makes it harder to measure the actual climate impact of new road construction or expansion projects.
