Diesel emissions at the Port of Long Beach dropped for the fifth consecutive year since the port’s Clean Air Action Plan was adopted in 2006.
The Long Beach inventory of emissions for 2011 shows a reduction in all categories of pollution. Diesel particulate matter plunged 75 percent from the 2005 baseline. Nitrogen oxides were down 50 percent and sulfur oxides dropped 80 percent. Greenhouse gases declined 23 percent.
Although cargo volume declined 10 percent last year, port executives attribute most of the emission reductions to the success of the CAAP that was adopted jointly by Long Beach and the neighboring Port of Los Angeles.
“Our clean air programs are effectively reducing air pollution from port sources – the numbers clearly demonstrate that,” said Susan Anderson Wise, president of the Long Beach Board of Harbor Commissioners.
The use of low-sulfur fuel and slow steaming to port by ocean vessels were cited as major reasons why emissions declined. The port’s clean-truck program that replaced thousands of older vehicles with new trucks was also an important factor.
Wise said additional measures will be required if the port is to reach its long-term emissions reduction goals. Long Beach and Los Angeles in 2010 updated the CAAP to include more stringent emissions reduction measures.
