As UN Ocean Conference opens in France, a push to turn promises into protection

THE third UN Ocean Conference opened on Monday as pressure mounts for nations to turn decades of promises into real protection for the sea.

French President Emmanuel Macron, delivering the keynote address in the host city of Nice, urged countries to move "from words to deeds" in safeguarding the oceans.

He warned "the fight for the ocean is at the heart of the years-long battles we've been waging - for biodiversity, climate, our environment and health".

The conference comes as just 2.7 per cent of the ocean is effectively protected from destructive extractive activities, according to the nonprofit Marine Conservation Institute.

That's far below the target agreed under the "30x30" pledge to conserve 30 per cent of land and sea by 2030.

Atop this year's agenda is ratification of the High Seas Treaty. Adopted in 2023, the treaty would for the first time allow nations to establish marine protected areas in international waters, which cover nearly two-thirds of the ocean and are largely ungoverned.

"It's the Wild West out there with countries just fishing anywhere without any sort of regulation, and that needs to change," said Mauro Randone, regional projects manager at the World Wildlife Fund's Mediterranean Marine Initiative.

"The high seas belong to everyone and no one practically at the same time, and countries are finally committing to establish some rules."

The ocean is critical in stabilising Earth's climate and sustaining life. It generates 50 per cent of the oxygen we breathe, absorbs around 30 per cent of carbon dioxide emissions and captures more than 90 per cent of the excess heat caused by those emissions. Without a healthy ocean, experts warn, climate goals will remain out of reach.

The treaty will only come into force once 60 countries ratify it. As of Monday, just 32 countries had. Advocates hope UNOC can build enough momentum to cross the threshold, which would allow for the first official Oceans Conference of Parties.
