The Port of Los Angeles has entered into separate Memorandum of Understandings (MOUs) with the Port of Tokyo and the Port of Yokohama – to more formally collaborate on sustainability and environmental issues. The agreements were signed by Port of Los Angeles officials during the 2023 California Japan Clean Energy Trade Mission and calls for cooperation and sharing of best practices on environmental and sustainability initiatives, including the digitation of the supply chain to optimize efficiency and reduce port operational impacts.
