San Pedro Bay Ports' Clean Air Action Plan Best Practices and Lessons Learned

The Clean Air Action Plan (CAAP) at the Ports of Los Angeles and Long Beach, collectively known as the San Pedro Bay Ports (SPBP), is a groundbreaking program. The Case Study of the San Pedro Bay Ports’ Clean Air Action Plan 2006–2018 provides a summary of the CAAP’s background and history followed by three focused discussions on environmental justice and levers of community influence; technologies and practices for development and deployment; and the 2017 Clean Truck Program. Best practices and lessons learned presented in the case study that other port operators and near-port communities may find useful when implementing air quality actions include the importance of:

CAAP Origins and Background

The San Pedro Bay Ports (SPBP) are the entry point for up to 40 percent of U.S. containerized cargo imports. As the SPBP capacity to transfer cargo expanded with the rapid growth of international trade in the early 2000s, so did diesel-powered vehicles and equipment, that continued the ports’ role as being a large contributor to the region’s poor air quality. In 2000, the South Coast Air Quality Management District (SCAQMD) published a study that reported a high risk of cancer resulted from air pollution from diesel exhaust. The study raised public awareness of the health effects of air pollution, and near-port communities began mobilizing to oppose the Ports’ expansion and demanded action to improve air quality. SPBP leaders were also becoming increasingly aware of a trend toward stricter environmental regulations and saw potential cost savings in taking pre-emptive environmental action. In response, the ports and partners developed the CAAP in 2006, with subsequent revisions in 2010 and 2017. The CAAP reflects a process of continuous stakeholder engagement that can serve as a roadmap for other port operators considering air quality actions and for near-port communities interested in advocating for their health and wellbeing in partnership with ports.

CAAP Development and Implementation

The Ports developed the CAAP to be a living document: each update includes new data and strategies as information and technology became available. Each version of the CAAP addresses the “fair share” of the Ports’ pollutant emissions that were contributing to regional air quality problems; tailors control strategies to specific emission source types (i.e., vessels, heavy-duty trucks, cargo-handling equipment, etc.); and reflects the most recent, accurate annual emissions inventories and estimates. There were two updates to the original 2006 CAAP: 2010 and 2017. Key elements and outcomes of each version are presented below.

Built on engagement, collaboration, and information sharing, productive community-port working relationships are fluid, time-intensive, and essential to the success of port environmental programs. Community-port collaborations do not need to start with a fully comprehensive clean air plan, and ports just beginning outreach and communication efforts will likely need to take incremental steps.

Lesson Learned: Emission Inventories, Quantified Targets, and Technical Innovations

Developing emissions inventories can help ports set quantitative targets and determine where to reduce emissions, while also providing timely information to demonstrate the effectiveness of clean air efforts to the surrounding community. Technical innovations, including through technology demonstrations and changes to operational practices, can support emission reductions while maintaining a balance with economic viability.

Lesson Learned: Partnerships with Government and Industry

Collaboration with state and local governments, along with the shipping industry and technology developers and manufacturers, were crucial for CAAP development and implementation. Governments can direct money toward port projects that reduce emissions, develop voluntary incentive programs, partner with port entities to obtain additional resources, and—when appropriate—develop cost-effective regulations to reduce emissions.
