The Ports of Los Angeles and Long Beach are the two busiest marine container ports in the nation. In 2006 the Ports jointly adopted their first Clean Air Action Plan (CAAP). This plan was updated in 2010 and again in 2017. Implementation of the CAAP, as well as a variety of CARB regulations, led to significant early emission reductions of Diesel Particulate Matter (DPM, a toxic carcinogen), Sulfur Oxides (SOx, a key component of regional particulate matter), and Nitrogen Oxides (NOx, a key contributor to regional smog). Emission reductions have continued in recent years, but at a slower pace. The ports remain the largest contributor to NOx in our region, and DPM emissions from port sources continue to disproportionately impact neighboring communities. For this reason, emission reduction control measures have been included in the 2016 Air Quality Management Plan as well as the AB 617 Community Emission Reduction Plan for the Wilmington, Carson, West Long Beach.

This proposed facility-based measure seeks to develop specific actions that the ports can take to significantly reduce emissions from their operations, including through implementing the CAAP or other measures that ultimately will assist with achieving air quality standards and reduce impacts on nearby communities.
