After the first two Conferences in New York (2017) and Lisbon (2022), France and Costa Rica are jointly organizing the third United Nations Ocean Conference (UNOC3) in Nice, from 9 to 13 June 2025. Ten years after COP21 and the Paris Agreement, UNOC3 is seeking to bring together all United Nations Member States, specialized agencies, civil society, the private sector and international donors, and through the Nice Ocean Agreements, achieve what was achieved for the climate with the Paris Agreement in 2015.
