In 2019, the Board of Port Commissioners (Board) adopted a resolution authorizing Port staff to update the Port's 2007 Clean Air Program to align with State programs, develop District-related strategies, and identify projects that would reduce emissions and improve air quality. This update has evolved into the proposed project, the Maritime Clean Air Strategy (MCAS), which is a planning document that identifies long and near-term goals and policies, and identifies potentially feasible strategies and measures, to help reduce emissions while promoting maritime operations.
The MCAS provides a framework for the Port to assist in identifying future projects and initiatives in the near and long-term to improve health through cleaner air for all who live, work, and plan on and around San Diego Bay. Near-term goals and objectives aim to be achieved by June 30, 2026, whereas long-term goals and objectives aim to be achieved by 2030. Near-term goals will help accelerate the deployment of zero emission technologies and build confidence in the marketplace. One of the near-term objectives includes a commitment to complete a comprehensive update to the MCAS in 2025, that will include more specificity for year 2030, when more information is known. Goals and objectives are tied to the seven maritime emission sources (cargo handling equipment, harbor craft, ocean-going vessels, trucks, rail, shipyards, and Port fleet) and stakeholder priorities (public health, community enrichment, and enabling).
