Ocean Summit in Nice: Emmanuel Macron Announces Implementation of High Seas Treaty

“To the fifty or so ratifications already deposited here in the past few hours, fifteen more countries have formally committed to joining,” stated the French head of state, celebrating a key milestone in protecting two-thirds of the planet’s ocean surface. Once the 60th ratification is officially confirmed, the treaty will enter into force 120 days later.

A Historic Treaty for a Global Common Good

The High Seas Treaty, also known as BBNJ (Biodiversity Beyond National Jurisdiction), marks a major breakthrough in international ocean governance. It aims to regulate marine biodiversity in areas beyond national jurisdictions — zones frequently exposed to overexploitation, illegal fishing, and unregulated extractive ambitions.

Guterres Warns Against a “Wild West” in the Deep Sea

In a powerful speech, UN Secretary-General António Guterres warned against descending into unrestrained ocean exploitation:
“The deep sea cannot become a Wild West. I hope we can change course — to replace plundering with protection,” he declared.

His remarks came at a time when some states — notably the United States under former President Donald Trump — have expressed interest in unilaterally launching deep-sea mining projects in the Pacific’s international waters.

Macron: “The Abyss Is Not for Sale”

Emmanuel Macron also issued a thinly veiled warning to powers eyeing seabed resources:
“The abyss is not for sale. No more than Greenland, Antarctica, or the high seas,” he declared, in an implicit critique of Donald Trump’s past proposal to buy Greenland — a Danish autonomous territory rich in minerals. Macron is scheduled to visit Greenland on June 15, in a strong symbolic move.

A High-Profile Conference: Nice as the “Blue Capital” for a Week

The city of Nice is hosting over 100 delegations, including 50 heads of state or government — such as Brazilian President Lula da Silva — and thousands of scientists, diplomats, NGOs, and climate stakeholders, until Friday, June 13. This massive mobilization reflects the urgency of the climate and ecological crisis.

Held in a setting as iconic as it is alarming — the Mediterranean, which reached a record temperature of 28.9°C in summer 2024 — the conference aims to produce a joint declaration, the result of months of negotiations, along with concrete commitments to protect marine ecosystems.

A Summit to Usher in a New Era for Maritime Law

This treaty — the product of two decades of international negotiations — could become the central legal tool for protecting the planet’s most vulnerable marine areas. That is, if the promises made are followed by concrete and coordinated action.
