Why ATA’s Push to Weaken EPA Heavy‑Duty Standards Hurts the Trucking Industry

A coalition of environmental, health, and labor organizations argues that the American Trucking Associations' (ATA) push to weaken EPA heavy-duty NOx standards would harm public health, burden truck drivers, and hinder US market competitiveness. The authors assert that manufacturers are prepared for the 2027 benchmarks and that the transition to cleaner technology is essential to reduce the disproportionate pollution caused by heavy-duty vehicles.

• The authors argue that weakening the EPA's NOx rule would lead to "technological stagnation" and lock trucking fleets into "dirtier, less efficient engines," which would increase long-term costs for drivers and fleets amid diesel price volatility.
• Heavy-duty vehicles are identified as a major pollution source, accounting for 59% of the transportation sector's NOx emissions and 55% of its particulate pollution, despite making up only 6% of the on-road fleet.
• The document highlights the severe health risks for truck drivers due to "in-cabin pollution," which the American Lung Association links to higher mortality rates from lung cancer compared to unexposed workforces.
• The authors claim that major manufacturers have already confirmed their ability to meet the 2027 benchmarks, citing PACCAR, Cummins, and Daimler as companies that are prepared or have already developed engines meeting the 2027 heavy-duty NOx standard.
• The letter states that the technology required for compliance, specifically evolutions of selective catalytic reduction (SCR) and aftertreatment systems, is already cost-effective and has been used for 15 years.
