EPA issues ANPR on Clean Trucks Initiative, seeking input from public and stakeholders

Green Car Congress

The US EPA issued an Advance Notice of Proposed Rulemaking (ANPR) for the Cleaner Trucks Initiative (CTI). 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%.
