Southwest Research Institute engineers have developed the next generation of clean diesel engine technology to reduce hazardous nitrogen oxides (NO x ) and carbon dioxide emissions while minimizing fuel consumption. In 2013, CARB contracted SwRI to investigate potential approaches for achieving an ultra-low NO x target in three stages.

The study found the potential for 1,500–2,000 Bering Strait transits in 2025, a three- to four-fold increase from 440 transits in 2013 (based on the medium-growth scenario). Most recently MARPOL was amended through the “1997 Protocol,” which added Annex VI, Regulations for the Prevention of Air Pollution from Ships. Earlier post.).

demonstrates that mandatory upgrades to diesel truck fleets serving the Port of Oakland are responsible for significant reductions in two major air pollutants. Pollutant concentrations were measured at high time resolution in the exhaust plumes of more than a thousand drayage trucks as they drove toward the Port on a major access road.
