Green Car Congress
JANUARY 7, 2020
The eventual CTI rulemaking will establish new, more stringent emission standards for NO x and other pollutants for highway heavy-duty engines. From 2007 to 2017, US NO x emissions dropped by more than 40%. EPA last revised NO x standards for on-highway heavy-duty trucks and engines in January 2001. The EPA Administrator announced in November 2018 that EPA would pursue the Cleaner Trucks Initiative (CTI) to update NO x emissions standards for heavy-duty trucks.
