From the 9th to the 13th of June 2025, France will co-host, with Costa Rica, the Third United Nations Ocean Conference (UNOC3). For this crucial event, around 100 Heads of State and Government will gather in Nice, as well as tens of thousands of researchers, scientists, economic actors, activists and citizens from around the world. On this occasion, France’s aim will be clear: protecting the Ocean through tangible action.

The Ocean is our common good. It feeds and protects our peoples. It makes us dream and travel. It provides us with sustainable energy, trade, resources and infinite scientific knowledge.

One person out of three relies on the Ocean for livelihood, yet the Ocean is in danger. It’s an area that is still largely unknown, and lacks the global governance and funding necessary for its preservation. The figures are worrying: more than eight million tons of plastic end up in the Ocean every year, according to a study published in the journal Science. Moreover, more than a third of fish stocks suffer overfishing, while ocean acidification, rising sea levels and the destruction of marine ecosystems gain pace, as direct consequences of climate change.

We must act now. More than ever before, we must make sure that multilateral action is equal to the challenges of protecting the Ocean.

Ten years after COP21 and the Paris Agreement, which established a binding global framework to limit climate change, the third United Nations Ocean Conference is a historic opportunity. The “Nice Ocean Agreements” can form an international pact for the conservation and sustainable use of the Ocean, fully in line with the Sustainable Development Goals adopted by the United Nations in 2015.

To this end, the talks in Nice need to be operational and action-focused, aiming for better governance, further financing and greater knowledge of the seas.

When it comes to governance, the Agreement under the UN Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas beyond National Jurisdiction (BBNJ Agreement) is essential. The high seas, which represent more than 60% of the Ocean, are currently the only area not governed by international law. The lack of surveillance and common rules is causing a real social and environmental disaster, with massive hydrocarbon and plastic pollution, illegal and unregulated fishing techniques, and the capture of protected mammals. To end this legal vacuum, we need the BBNJ Agreement to be ratified by 60 countries, so as to come into force.

We are delighted to be able to count on the commitment of Greece to the entry into force of the BBNJ Agreement. Together, committed to protecting the oceans, we will celebrate this great victory in Nice.

Generally speaking, the protection of the Ocean also requires public and private financing, and support for a sustainable blue economy. To continue enjoying the incredible economic opportunities offered by the Ocean, we need to make sure marine resources can regenerate.

In Nice, several commitments will be announced for global trade, shipping, tourism and investment.

Lastly, how can we protect something that we don’t – or insufficiently – know? We need to enhance our knowledge of the Ocean and disseminate it more effectively. Today, we are capable of mapping the surface of the Moon or of Mars, but the depths of the Ocean – which covers 70% of Earth’s surface – remain unknown. Together, let’s mobilize science, innovation and education to better understand the Ocean and raise public awareness.

In the context of ever faster climate change and overexploitation of marine resources, the Ocean is not an issue like any other. It’s everyone’s business.

As a leading maritime nation, Greece can make a difference – as the ambitious announcements made at the “Our Ocean Conference” hosted in Athens in 2024 clearly showed – and we are sure that it will make a valuable contribution to the UNOC3. France will therefore be delighted to welcome in Nice Prime Minister Mitsotakis and the Greek delegation for this major event in support of ocean protection.
