Ships in the port of Nice sounded their fog-horns on Friday, a brassy crescendo to a rare moment of global unity as the Third UN Ocean Conference drew to a close.

Moments earlier, more than 170 countries had adopted by consensus a sweeping political declaration promising urgent action to protect the ocean.

“We close this historic week not just with hope, but with concrete commitment, clear direction, and undeniable momentum,” Li Junhua, Under-Secretary-General for Economic and Social Affairs and Secretary-General of the summit, told reporters.

Co-hosted by France and Costa Rica, the five-day event brought 15,000 participants, including more than 60 Heads of State and Government, to France’s Mediterranean coast.

With over 450 side events and nearly 100,000 visitors, the gathering, dubbed UNOC3, built on the momentum of previous ocean summits in New York (2017) and Lisbon (2022). It culminated in a shared call to expand marine protection, curb pollution, regulate the high seas, and unlock financing for vulnerable coastal and island nations.

Ambitious pledges

The conference’s outcome, known as the Nice Ocean Action Plan, is a two-part framework that comprises a political declaration and over 800 voluntary commitments by governments, scientists, UN agencies, and civil society since the previous conference.

“These range from advocacy by youth to deep-sea ecosystem literacy, capacity building in science and innovation, and pledges to ratify intergovernmental treaties,” Mr. Li said.

The pledges unveiled this week reflected the breadth of the ocean crisis. The European Commission announced an investment of €1 billion to support ocean conservation, science, and sustainable fishing, while French Polynesia pledged to create the world’s largest marine protected area, encompassing its entire exclusive economic zone – about five million square kilometers.

Germany launched a €100-million programme to remove underwater munitions from the Baltic and North Seas. In addition, New Zealand committed $52 million to strengthen ocean governance in the Pacific, and Spain announced five new marine protected areas.

A 37-country coalition led by Panama and Canada launched the High Ambition Coalition for a Quiet Ocean to tackle underwater noise pollution. Meanwhile, Indonesia and the World Bank introduced a ‘Coral Bond’ to help finance reef conservation in the country.

“The waves of change have formed,” Mr. Li said. “It is now our collective responsibility to propel them forward – for our people, our planet, and future generations.”
