Truckers, builders celebrate repeal of carbon emissions rule for highways
- On April 18, 2025, the U.S. Department of Transportation, under the leadership of Secretary Sean Duffy, officially withdrew a Biden-era regulation that required states to establish and report greenhouse gas emission targets for highways.
- The rule originated to reduce carbon dioxide emissions by establishing performance metrics for state transportation agencies but faced lawsuits from multiple Republican-led states and opposition over its legal authority.
- Supporters of the repeal argue the regulation would have imposed costly mandates, disrupted local priorities, and created bureaucratic barriers, while some climate advocates have expressed concerns about lost federal emissions oversight.
- Secretary Duffy announced that he eliminated the excessive climate mandate to prevent any extreme political influences from obstructing efforts to upgrade the nation’s highways, reflecting the administration’s commitment to fostering economic growth and aligning policy accordingly.
- The repeal, effective May 19, 2025, gained backing from trucking groups, road builders, and state highway officials who see it as removing regulatory burdens and restoring state autonomy over transportation planning.
