UN adopts ‘historic’ treaty to protect the high seas, ecosystems vital to humanity
- The landmark accord will establish a legal framework to extend swathes of environmental protections to international waters
- After more than 15 years of discussions, including 4 years of formal negotiations, UN member states finally agreed on the text for the treaty

The world’s first international treaty to protect the high seas was adopted on Monday at the United Nations, a landmark environmental accord designed to protect remote ecosystems vital to humanity.
Secretary General Antonio Guterres hailed as a “historic achievement” the treaty that will establish a legal framework to extend swathes of environmental protections to international waters, which make up more than 60 per cent of the world’s oceans.
Following more than 15 years of discussions, including four years of formal negotiations, UN member states finally agreed on the text for the treaty in March after a flurry of final, marathon talks.
The text, since frozen, has been pored over by the UN’s lawyers and translators to make sure it matches in the body’s six official languages.
“Healthy oceans, from coastal waters to remote high seas and deep seabed areas, are integral to human health, well-being, and survival,” a group of scientists noted in The Lancet journal.

Scientists have increasingly come to realise the importance of oceans, which produce most of the oxygen we breathe, limit climate change by absorbing CO2, and host rich areas of biodiversity, often at the microscopic level.
