The latest diesel emissions inventory released by the Port of Los Angeles shows that the Clean Air Action Plan reduced pollution more than 70 percent in 2010 even as cargo volume rose by 5 percent, the Journal of Commerce reported.
The report states that sulfur oxide emissions per 10,000 TEUs plummeted 76 percent and diesel particulate matter emissions dropped 71 percent since the port’s first inventory taken in 2005.
Since 2005, Nitrogen oxide emissions fell 52 percent, carbon monoxide dropped 48 percent and hydrocarbon emissions decreased 45 percent. DPM is classified as a toxic air contaminant and known carcinogen and NOx and SOx are key components of smog.
Emissions associated with cargo handling operations show DPM emissions down 39 percent from 2009. NOx emissions dropped 25 percent and SOx emissions declined 45 percent last year compared to 2009.
The emissions inventory measures actual records of activity by ships, trucks, trains, cranes and other yard equipment. The technique was developed in cooperation with the South Coast Air Quality Management District and the California Air Resources Board to ensure accuracy.
“This is the second straight year we have achieved dramatic reductions in every emissions category,” said Geraldine Knatz, executive director of the Port of Los Angeles. She cited the port’s vessel speed reduction program and clean-truck plan as key factors in the emissions reductions.
