Nov. 14, 2018—On Tuesday, the United States Environmental Protection Agency (EPA) announced its Cleaner Trucks Initiative. This initiative includes a future rulemaking to establish updated standards to address oxides of nitrogen (NOx) emissions from the engines of heavy-duty, on-highway trucks.
The Truck and Engine Manufacturers Association (EMA) said it supports the initiative. Over the past 20 years EMA manufacturers have innovated and implemented advanced clean technologies to reduce NOx emissions by over 90 percent and particulate emissions by over 98 percent.
It’s been 20 years since EPA last set NOx emission standards for heavy-duty truck engines, and those standards were set in accordance with a certification and compliance program architecture that evolved from roots established almost 40 years ago.
