Informal summary report of the ocean and climate change dialogue 2025
The ocean and climate change dialogue (“dialogue”) was mandated by the Conference of the Parties at its twenty-sixth session. The 2025 dialogue was held in hybrid mode on 17–18 June 2025, in conjunction with the sixty-second session of the subsidiary bodies in Bonn, Germany. As the co-facilitators of the dialogue, we have prepared this report that provides a summary of the discussions that took place on three topics, chosen in consultation with Parties and observers: first, Ocean-based measures in the Nationally Determined Contributions, second, the ocean under the Global Goal on Adaptation, and third, Ocean-climate-biodiversity synergies. The cross-cutting issues included means of implementation, particularly finance, as well as science.
The dialogue offered a vital space for enhancing collaboration, understanding and building ocean-based climate action, illustrating needs, opportunities and case studies, as well as highlighting key messages for consideration at COP30.
We encourage Parties to read these messages in conjunction with and as a complement to the key messages of the previous informal summary reports of the 2023 and 2024 ocean dialogue.
