Abstract
(S3007 · 119th Congress) Latest action (2025-10-14): Read twice and referred to the Committee on Environment and Public Works.
Why this matters
Diesel heavy-duty trucks are a major source of NOx and particulate emissions, and federal standards set the trajectory for both compliance costs on truck manufacturers/fleets and public health impacts in freight corridors. A statutory rollback would constrain EPA’s ability to tighten heavy-duty emissions rules and could shift the cost-benefit balance away from air-quality and health improvements toward lower vehicle and fuel costs. At introduction with no committee action, its practical effect is signaling only.
