On November 13, EPA announced the Cleaner Trucks Initiative (CTI) to further decrease nitrogen oxide (NOx) emissions from on-highway heavy-duty trucks and engines.
The CTI will include a future rulemaking that will update the existing NOx standard which was last set in 2001 while also streamlining compliance and certification requirements. EPA intends to publish a proposed rule in early 2020. This action follows petitions for rulemaking from over 20 organizations, including from state and local air agencies across the country.
