The One Ocean Science Congress will be held in Nice, France on 3-6 June, 2025.
There is One Ocean
There is One Ocean, a global common and a critical resource to human prosperity and well-being. It plays a crucial role in regulating the climate and supporting the livelihoods of three billion people, the vast majority in developing countries.
Climate change, overfishing, pollution, and conflict use
The Ocean is under threat from combined pressures such as climate change, overfishing, pollution, and conflicting uses. It is also a source of solutions, for example to mitigate and adapt to climate change. The Ocean urgently needs decisive, swift, and unified efforts to address its critical condition and maximize the solutions it offers. This presents a major challenge for the global community at the Third United Nations Conference on the Oceans (UNOC3), to be held in Nice from 9 to 13 June 2025. The goal is to spur action and implement SDG 14, which is the least funded of all Sustainable Development Goals.
A UNOC3 Special Event dedicated to Science
CNRS and IFREMER have been tasked with organizing the One Ocean Science Congress (OOSC), a UNOC3 Special Event dedicated to Science, and to provide Heads of State, Government, and the broader society, with comprehensive scientific insights on the Ocean's health and future trajectory. Science-informed decisions should enable the conservation and sustainable use of the Ocean, optimize the solutions it offers, and safeguard the services and benefits it provides to humanity.
About the One Ocean Science Congress
The Congress will feature a mix of plenary sessions, including opening and keynote speeches, alongside parallel oral and poster presentations. To enhance interactions between science and society, action and policy, and to engage civil society more broadly, 'townhalls' such as panels and roundtables will also be arranged.
Key themes
- Integrating knowledge systems, with a focus on responsibility and respect for the ocean
- Effectiveness, equitability and safety of ocean-based approaches to reach the mitigation and adaptation goals of the Paris Climate Agreement
- Protection and restoration of marine and coastal ecosystems to ensure sustainable and equitable management
- Knowledge of the deep ocean and ways to enable its sustainable use
- Marine genetic resources: from discovery to equitable access and sharing of associated benefits
- Transparency in the fisheries sector, including illegal, unreported and unregulated fishing
- Sustainability, equitability, and safety of ocean-based food systems
- Marine plastic pollution
- Environmental footprint of maritime transport and decarbonization of shipping
- Vibrant science to inform and support ocean action
