Port of Long Beach
LONG BEACH — The Port of Long Beach reported that historic supply chain disruptions, COVID-19 restrictions, and record cargo volumes combined to create unprecedented numbers of ships waiting along the coast and congestion at the San Pedro Bay port complex, driving up emissions in 2021. Despite these unprecedented factors, the POLB continued to move ahead in developing zero-emissions technology in its quest to become a zero-emissions port.
The port’s annual emissions inventory report, presented to the Long Beach Board of Harbor Commissioners on Oct. 3, found diesel soot is down 88%, nitrogen oxides have decreased 49%, and sulfur oxides have decreased 96% compared to 2005. In the prior study year, diesel particulates had decreased 90%, nitrogen oxides 62%, and sulfur oxides 97%. The port uses a baseline of 2005, the year before the original San Pedro Bay Clean Air Action Plan or CAAP was adopted.
The global supply chain congestion last year resulted in a series of events causing the rise in emissions in San Pedro Bay. Specifically, a large number of vessels, mainly container ships, sat at anchor or loitered during cargo surges. When the ships berthed at terminals where a COVID-19 safety agreement capped the size of work groups, the vessels stayed longer. More cargo-handling equipment was used to keep up with the activity, and trucks waited longer in queues as a result of systemwide logistics issues in the Harbor District, across the region, and throughout the nation. Additionally, a higher than usual number of visiting ships were not equipped with shore power, and other ships used less shore power due to a California emergency energy-restriction order event.
The port continues to meet its 2023 targets for diesel particulate matter and sulfur oxides. In the previous inventory, greenhouse gas emissions were down 10% compared to 2005. In this year’s inventory, greenhouse gas emissions are up 22% since 2005. The increase was mainly due to the unusually large number of oceangoing vessels staying at anchor off the coast.
In November 2021, the shipping industry created a new ship queuing system to largely eliminate ships at anchor by keeping waiting vessels farther off the coast. Today, the number of container ships at anchor in San Pedro Bay is seven, a significant reduction from the peak of 109 ships in January 2022. Preventing congestion will effectively reduce ship emissions in the future.
In order to tackle greenhouse gasses and criteria pollutants, the Port of Long Beach has set a goal of all zero-emissions cargo-handling equipment by 2030 and a zero-emissions drayage truck fleet by 2035. About 17% of the cargo-handling equipment at the port is electric powered, the largest such fleet in the United States. As a signal of that progress, last month, the port announced that a trucking company partner will convert to fully-zero emissions by 2025 – 10 years before the 2035 goal.

Since 2021, the port has put in place a number of initiatives to further reduce air pollution in future inventories and build a technological and operational bridge to a zero-emissions future. These include:
The annual emissions inventory is reviewed by the U.S. Environmental Protection Agency, California Air Resources Board and South Coast Air Quality Management District. Learn about the Port’s emissions inventory here./https://www.epa.gov/air-emissions-inventories
