Third United Nations Conference on the Oceans (UNOC3)

UNOC3 will be focused on “Accelerating action and mobilising all actors to conserve and sustainably use the ocean”. The conference aims to foster urgent and expanded action to conserve and sustainably use the ocean, seas, and marine resources for sustainable development and to identify further ways to support the implementation of Sustainable Development Goal 14. It will build on existing instruments to forge effective partnerships toward the swift conclusion and efficient implementation of ongoing processes that contribute to the conservation and sustainable use of the ocean. The conference will involve all relevant stakeholders, bringing together governments, the United Nations system, intergovernmental organisations, international financial institutions, other interested international agencies, non-governmental organisations, civil society organisations, academic institutions, the scientific community, the private sector, philanthropic organisations, Indigenous peoples and local communities, and other stakeholders to assess the challenges and opportunities related to the implementation of Goal 14 and the measures taken toward that end.

In addition to the plenary session bringing together the 193 Member States of the United Nations, dialogue sessions will be held bringing together Member States, international organisations and representatives of civil society (NGOs, scientists, businesses). These dialogues, the Ocean Action Panels, will highlight the commitment of the various players and the creation of coalitions and projects in favour of the Ocean. They will help to anchor the Conference in action by proposing concrete solutions with all the participants.

The conference will be preceded by three special events: the One Ocean Science Congress (June 4-6, 2025, in Nice), the Blue Economy and Finance Forum (June 7-8, 2025, in Monaco), and the Ocean Rise & Coastal Resilience Coalition (June 7, 2025, in Nice).
