Through its just-announced Cleaner Trucks Initiative (CTI), EPA aims to further decrease nitrogen oxide (NOx) emissions from on-highway heavy-duty trucks and update a current engine exhaust standard in an early-2020 rulemaking. Set in 2001, the standard culminated in 2010 with a 0.2-gram brake-horsepower-hour NOx threshold for which engine manufacturers deployed selective catalytic reduction equipment and urea-based diesel exhaust fluid.

EPA- and National Highway Traffic Safety Administration-proposed performance standards covering 2021–2027 model year heavy- and medium-duty trucks would achieve up to a 24 percent reduction of fuel consumption and carbon dioxide emissions when measured against a 2018 vehicle. The agencies address concrete mixers and dump trucks within a larger Vocational Vehicles category of heavy- and medium-duty models, representing what officials estimate is about 20 percent of fuel consumption in the transportation universe their proposal covers.
