• U.S. Chamber Testimony for EPA's Virtual Public Hearing on Control of Air Pollution from New Motor Vehicles: Heavy-Duty Engine Standards

April 13, 2022

Thank you for the opportunity to present comments on behalf of the U.S. Chamber of Commerce.

Since 1990, economy-wide NOx emissions from highway vehicles have declined by 75%, even as overall vehicle miles traveled have increased by nearly 50%.

Continued improvements in advanced technology diesel engines are a key driver of this success and one of many reasons U.S. air quality is among the cleanest in the world.
