The Port of Long Beach has approved an addendum to a joint zero-emission infrastructure agreement with the Port of Los Angeles and the South Coast Air Quality Management District (South Coast AQMD).
The Long Beach Board of Harbor Commissioners approved the addendum on 10 August, following approval by the South Coast AQMD Governing Board on 7 August. The Los Angeles Board of Harbor Commissioners is scheduled to consider the same measure on 13 August.
The underlying cooperative agreement was approved in December 2025 and requires the two ports to develop zero-emission infrastructure plans covering five major categories of mobile equipment and transport operating in and around the San Pedro Bay port complex.

Under the latest addendum, three additional measures would be incorporated into the agreement. The ports would implement a truck utilisation incentive programme, enhance the Environmental Ship Index incentive programme and develop a memorandum of understanding to provide $20 million to South Coast AQMD for regional truck infrastructure.
The addendum also commits the ports to prepare five environmental studies or projects. Details of those studies are not set out in the summary presented to the Los Angeles Harbor Commission.
The three new measures are not final implementation approvals. According to the Los Angeles Harbor Department, each measure will be brought to the respective boards individually for consideration once it has been fully developed. The term of the cooperative agreement remains unchanged and runs through 31 December 2030.
The agreement covers infrastructure planning for cargo-handling equipment, harbour craft, trucks, trains and ocean-going vessels. The ports are developing the plans in three phases, beginning with a draft in May 2027, while approved plans covering all emissions categories are required by the end of 2029.
The latest Long Beach decision adds the proposed incentive and infrastructure measures to that programme while retaining separate approval processes for their final design and implementation.
As of 11 August, Los Angeles has not yet approved the addendum. Its Harbor Commission agenda for 13 August recommends approval and authorisation for the Executive Director to execute the amended agreement.
If approved in Los Angeles, the addendum would have received backing from all three parties to the cooperative agreement. The individual measures, including the proposed $20 million regional truck infrastructure arrangement, would still return to the boards for further consideration.
