UNOC 2025 Special Events

One Ocean Science Congress

4-6 June 2025, Nice, France 

The aim of the One Ocean Science congress is to provide Heads of State, Government, all participants of the third United Nations Ocean Conference, and the broader society, with comprehensive scientific insights on the ocean’s health, dynamics and future trajectory, on its conservation and sustainable uses, and on the services and benefits it provides to humanity.

The congress aims to explore various scenarios for the ocean in terms of the changing pressures it faces, its resilience, its restoration ability and the impact on public policy and management practices at local and global levels. It will assess the ocean’s capacity to support significant transitions as outlined in the 2030 Agenda for Sustainable Development, particularly Sustainable Development Goal 14, which promotes the conservation and sustainable use of marine and coastal ecosystems.

Building on this wealth of knowledge, science-based recommendations will be formulated to the Heads of State and Government, who will meet in Nice at UNOC3, and to the wider international community, urging them to prioritize the ocean within the sustainable development framework and to increase funding for research into ocean solutions, infrastructure and the intersection of ocean policy and society.

Key partners: The One Ocean Science Congress is co-organized by the French National Centre for Scientific Research (CNRS) and French national institute for ocean science and technology (Ifremer).
