LOS ANGELES (CNS) - Emissions of cancer-causing pollutants from diesel- powered equipment and vehicles at the Port of Los Angeles have taken a 79 percent dive since 2006, when measures to cut port pollution were first adopted, port officials announced today.

Overall, pollution due to port activity continued to be on the decline,  according to a presentation on 2012 air pollution readings heard by the Board of Harbor Commissioners, which overseas the Port of Los Angeles.

In addition to the drop in diesel particulate matter, sulfur dioxide emissions since 2006 were down 88 percent and nitrogen dioxide emissions dropped 56 percent, officials said.

The impact of port pollution on the Los Angeles basin also has lessened when compared with 2005 levels.

In 2012, sulfur dioxide originating from the port made up 6 percent of the overall amount throughout the region, down from 25 percent in 2005, while nitrogen dioxide made up 3 percent. Diesel particulate matter generated at the ports was 4 percent of the region's emissions in 2012.

“Every year really does count and our systematic approach has accelerated our progress,” said Los Angeles Harbor Commission President Cindy Miscikowski. “Much of the credit is shared by our industry partners who have invested in technology that in some cases surpass government regulations.”

Clean air measures by the port include shifting trucks to cleaner- burning technology.
