Read the 17-Org Industry Letter to the Engine Manufacturers Association – 8/4/2025

Seventeen businesses, environmental advocates and public health organizations on Monday sent a letter to North America’s truck and engine manufacturers urging them to remain committed to the Clean Truck Partnership (CTP) agreed to in 2023… There is, however, debate over the validity of the agreement now that the Advanced Clean Trucks and CARB’s Omnibus regulations have been revoked by Congress. The Western States Trucking Association in June filed a petition with California’s Office of Administrative Law (OAL) challenging the CTP.
