The US Environmental Protection Agency (EPA) has launched the Cleaner Trucks Initiative (CTI) to further decrease NO x emissions from on-highway heavy-duty trucks and engines. The US has made major reductions in NO x emissions, but it’s been nearly 20 years since EPA updated these standards.

On 6 March 2020, the California Air Resources Board (CARB) proposed to set an intermediate FTP NO x emissions limit of 50 mg/bhp-hr in model years 2024-2026 with a final FTP standard of 20 mg/bhp-hr in 2027, representing a 90% reduction below today’s standard of 200 mg/bhp-hr.

Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. Establish a bio-bank of samples to support future HEI-sponsored research in this area.

CARB approved the State Strategy for the State Implementation Plan ( State SIP Strategy ), which describes CARB’s commitment for further reducing vehicle emissions needed to meet federal air quality standards over the next 15 years. The Board also approved the South Coast Air Quality Management District’s comprehensive air quality plan.

Use of electric vehicles would achieve greater reductions in GHG emissions, corresponding to the rate that the electric grid becomes cleaner, through greater reliance on renewables and low- and non-emitting generation. The study analyzes two potential scenarios of the future electric sector, the “Base GHG” and “Lower GHG” scenarios.

A longer service life reduces the fleet’s turnover rate to cleaner, lower-emitting engines, therefore increasing future-year emission estimates. Most tugs are operating in locations near America’s ports which do not meet current federal health-based air quality standards.
