2025 UN Ocean Conference
Nice, France | 9 June - 13 June 2025
Our Ocean, Our Future, Our Responsibility
"The ocean is fundamental to life on our planet and to our future. The ocean is an important source of the planet’s biodiversity and plays a vital role in the climate system and water cycle. The ocean provides a range of ecosystem services, supplies us with oxygen to breathe, contributes to food security, nutrition and decent jobs and livelihoods, acts as a sink and reservoir of greenhouse gases and protects biodiversity, provides a means for maritime transportation, including for global trade, forms an important part of our natural and cultural heritage and plays an essential role in sustainable development, a sustainable ocean-based economy and poverty eradication."
- political declaration of the 2022 united nations ocean conference
The high-level 2025 United Nations Conference to Support the Implementation of Sustainable Development Goal 14: Conserve and sustainably use the oceans, seas and marine resources for sustainable development (the 2025 UN Ocean Conference) will be co-hosted by France and Costa Rica and held in Nice, France, from 9 – 13 June 2025.
The overarching theme of the Conference is “Accelerating action and mobilizing all actors to conserve and sustainably use the ocean”. The Conference aims to support further and urgent action to conserve and sustainably use the oceans, seas and marine resources for sustainable development and identify further ways and means to support the implementation of SDG 14. It will build on existing instruments to form successful partnerships towards the swift conclusion and effective 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 organizations, international financial institutions, other interested international bodies, non-governmental organizations, civil society organizations, academic institutions, the scientific community, the private sector, philanthropic organizations, Indigenous Peoples and local communities and other actors to assess challenges and opportunities relating to, as well as actions taken towards, the implementation of Goal 14.
The Conference will build on the previous UN Ocean Conferences, hosted by Sweden and Fiji in 2017 in New York and by Portugal and Kenya in 2022 in Lisbon.
