​​​California’s leadership in sustainable trade took center stage in Tokyo o​​n Sept. 29, 2025,​ during a ​California trade mission​ ​​led​ ​​by ​​California State Treasurer Fiona Ma.​ The delegation​ ​brought together more than ​50 delegates from the California legislature, port authorities and ​private industry​​ for ​high-level talks with the Port of ​​Yokohama​ on port resiliency and sustainability.​

Representing Pacific Environment, Davina Hurt and Katsunori Hirano ​joined ​the 10-member delegation from the Port of Yokohama, led by Director General Yasuhiro Shimbo of the Port and Harbor Bureau of the City of Yokohama,​ to exchange ideas and strategies for building cleaner, more sustainable ports across the Pacific​. 

Three​ major​ California port authorities — the Port of Long Beach, Port of Los Angeles and ​Port of Hueneme​ — presented their ongoing efforts aimed at decarbonizing their respective ports. The city of Yokohama followed with a presentation, highlighting key strategies from its own port decarbonization plan​ launched in ​March​ 2025.​

The event culminated ​in ​a forward-looking discussion between the three California ports and the Port of Yokohama for future collaboration. Top executives — including Noel Hacegaba, Chief Operating Officer of the Port of Long Beach; Dina Aryan-Zahlan, Deputy Executive Director of Development for the Port of Los Angeles; Jason Hodge, Port of Hueneme Commissioner of the Oxnard Harbor District; and Yasuhiro Shimbo — demonstrated a strong commitment to building lasting partnerships.  

Pacific Environment played an active role in​ the event and​ aided in a constructive discussion​ post-event​, particularly around​ alternative clean energy and ​the development of green shipping corridors: dedicated routes on which zero-emission ships and other carbon-reducing infrastructure are deployed. We witnessed the city of Yokohama’s strong commitment to collaborative efforts ​and​ the state of California’s ​leadership in advancing port decarbonization and climate-aligned trade.​ 

​​This event marked a​n important​ step for Pacific Environment in ​strengthening ​trust with port leadership on both sides of the Pacific​. Through continued engagement, we aim to​ advanc​e​ a goal of fostering ​long-term​ communication and collaboration to reduce ​maritime ​emissions and promote clean energy through green shipping corridor initiatives​ and alternative fuel infrastructure​. We remain steadfast in our support of visionary port authorities — including the Ports of Long Beach, Los Angeles and Hueneme, as well as the Port of Yokohama — as they work toward the shared goal of transitioning to resilient and sustainable ports.​ ​​ 

​​​Strategies and trends were also discussed during the trade mission. ​It is clear that ​​Japan is pursuing a measured yet ambitious path toward maritime decarbonization. Some important points we learned during the mission include:​​​ 

  • Ammonia and methanol are emerging as leading alternative fuel strategies.
  • Ports and shipyards are at the heart of national demonstration projects.  
  • Finance and industry coalitions are emerging as crucial enablers of progress.  
  • NGO networks are bridging private and public sectors to accelerate climate action.  
  • Japan is positioning itself as a regional “fast follower,” emphasizing safety, scalability and cross-sector governance.  

​​​​The Japan-California trade mission re-affirmed the importance of ongoing face-to-face dialogue in managing ​​the global transition toward clean maritime trade.​​​​ ​​​We are deeply grateful to the city of Yokohama for welcoming us as part of the Port of Yokohama’s delegation and for the opportunity to contribute to this meaningful ​and timely ​dialogue.
