Port of San Diego focuses on electrification and bay protection

During Green Port Month in September, the Port of San Diego highlighted its progress in terms of improving air quality and the San Diego Bay’s protection. The port’s update relates the latest results from its Maritime Clean Air Strategy (MCAS), adopted in 2021 to reduce emissions from maritime activities.

The port and its partners have committed $240 million to maritime electrification and freight efficiency. These commitments support shore power improvements, the replacement of diesel-powered cargo-handling equipment with electric alternatives, and the introduction of the first fully electric tugboat in the United States. The report indicates the port has met 67% of its MCAS goals and implemented 88% of its objectives set for 2026.

According to the update, vessels connecting to shore power and using the emissions capture and control system at berth have achieved the following emission reductions:

• 75% for diesel particulate matter;
• 63% for nitrogen oxides;
• 30% for greenhouse gases.

The annual Green Port Year in Review also highlights the addition of 1,050 linear feet (320 metres) of Coastalock tide pool units along Harbor Island and the Sweetwater Channel. In addition, 200 employees volunteered to collect approximately 6,000 pounds (2.72 metric tons) of rubbish, while operations at Zuniga Shoals removed 84.3 metric tons of sunken vessels and marine debris.
