Taking Action to Clean the Air

The Port is committed to operating a clean port to improve the health of everyone who lives and works in the harbor area and ports around the world.


What is the Clean Air Action Plan?

The Port of Los Angeles launched the Clean Air Action Plan (CAAP) in 2006. The landmark initiative kicked off a new era of aggressive environmental measures targeting harmful emissions from ships, trains, trucks, harbor craft and off-road terminal equipment. CAAP is an ongoing program whose benefits include:

  • Accelerating the adoption of clean technologies
  • Achieving ongoing clean air gains
  • Mandating pollution control strategies
  • Improving regional air quality


Launching a New Era of Environmental Stewardship

The Port of Los Angeles, in partnership with the Port of Long Beach, made history in 2006 by adopting the San Pedro Bay Ports Clean Air Action Plan (CAAP), a sweeping program for reducing air pollution from all port-related sources. CAAP maps out specific strategies, milestones and goals for cutting harmful emissions from ships, trains, trucks, harbor craft and cargo handling equipment. The plan details pollution control, regulatory and operational measures for reducing diesel particulate matter (DPM), nitrogen oxides (NOx), sulfur oxides (SOx), greenhouse gases (GHG) and other primary pollutants associated with smog, health risks and climate change. Tracking annual progress and monitoring air quality in the harbor area and surrounding communities are essential plan components.

Pursuing Ongoing and New Clean Air Strategies

In addition to more than a dozen specific pollution control measures, CAAP strategies include leases requirements for Port tenants, Port-funded incentives, grants, and voluntary programs. The plan also incorporates requirements set by regulatory agencies, including those born out of strategies first developed in the San Pedro Bay ports. From the outset, CAAP was established as a living document that the Port periodically reviews and updates as it achieves clean air milestones. Working together, the Port of Los Angeles and the Port of Long Beach are now preparing the next major update as they move closer to CAAP’s ultimate goal of eliminating harmful air emissions from all port-related sources.

Accelerating Clean Technologies

The Technology Advancement Program (TAP) is another key component of the CAAP. Under TAP, the two ports established a fund to support testing new and emerging clean technologies. TAP grants defray the cost of demonstrating promising green technology and accelerating its availability in the marketplace.

Improving Air Quality in the San Pedro Bay Area and Southern California

Under CAAP, the Port of Los Angeles and the Port of Long Beach set stringent standards and goals for cleaning the air and improving the health of the San Pedro Bay region. Those standards and goals were established in collaboration with regional, state and federal air agencies to meet and exceed government clean air requirements. As a result of their aggressive strategies, the ports exceeded their 2023 targets for reducing DPM and SOx emissions in 2014 and are close to achieving their 2023 goal for reducing NOx emissions. The baywide standard for reducing health risk is the same as the state’s goal of reducing the residential cancer risk 85% by 2020 compared with 2005. The ports met that goal in 2014.
