The Ocean We Need for the Future We Want

Ocean Science for Sustainable Development

The Intergovernmental Oceanographic Commission (IOC) of UNESCO is the UN’s lead body for ocean science, promoting international cooperation to strengthen the management, sustainable use, and resilience of the ocean. Bringing together 153 Member States, the IOC coordinates global efforts in ocean observations and services, tsunami warning systems, ocean science, capacity development, and ocean literacy, ensuring that science effectively informs policy, society, and sustainable ocean governance. Through its work, the IOC contributes to UNESCO’s mission to advance scientific knowledge and build capacity as foundations for peace, societal progress, and sustainable development. As the coordinator of the UN Ocean Decade of Ocean Science for Sustainable Development (2021-2030), the IOC leads global efforts to transform ocean knowledge into action for the benefit of people and the planet. 

The 33rd session of the UNESCO-IOC Assembly will take place from 25 June-03 July 2025 at UNESCO HQ in Paris. The Assembly meets once per biennium with the purpose to review the work of the Commission, including the work of the Member States and the Secretariat, and formulate a common work plan for the coming two years.
