Since the Port of Long Beach began implementing its clean air programs in 2006, air pollution from port-related sources has been reduced every year, according to an “emissions inventory” study released on Monday that compares data from 2005 through 2011.

The study shows that all of the key air pollutants have experienced a reduction during this time period. This includes a 50 percent cut in smog-forming nitrogen oxides, an 80 percent cut in sulfur oxides, a 23 percent reduction in greenhosue gases and a dramatic 75 percent reduction in airborne diesel particulates.

These numbers are the positive results of the Clean Air Action Plan, which was jointly adopted by the ports of Los Angeles and Long Beach in 2006. It reflects the Ports’ efforts to aggressively limit or prevent the negative air impacts that result from the use of ships, trucks, tractors, locomotives and cranes that maneuver cargo around the port. During this time, the Port also switched to lower-sulfur fuels for all waterfront equipment as well as phased out old short-transport trucks, which were contributing major pollutants to the air. 

On July 1, the Port of Long Beach also began its Green Ship Incentive Program which provides cash benefits to shipping companies who bring the newest, cleanest vessels to the Port.
