UN member states have finally agreed to a text on the first international treaty to protect the high seas, a fragile and vital treasure that covers nearly half the planet.

After years of negotiations, negotiators from more than 100 countries completed the UN treaty – a long-awaited step that environmental groups say will help reverse marine biodiversity losses and ensure sustainable development.

“The ship has reached the shore,” conference Chair Rena Lee announced at the UN headquarters in New York shortly before 9:30 pm on Saturday (02:30GMT Sunday), to loud and lengthy applause from delegates.
The legally binding pact to conserve and ensure the sustainable use of ocean biodiversity, under discussion for 15 years, was finally agreed after five rounds of protracted UN-led negotiations.

The treaty is seen as a crucial component in global efforts to bring 30 percent of the world’s land and sea under protection by the end of the decade, a target known as “30 by 30” agreed in Montreal, Canada, in December last year.

The treaty will also oblige countries to conduct environmental impact assessments of proposed activities on the high seas.

Economic interests were a major sticking point throughout the latest round of negotiations, which began on February 20, with developing countries calling for a greater share of the spoils from the “blue economy”, including the transfer of technology.

An agreement to share the benefits of “marine genetic resources” used in industries like biotechnology also remained an area of contention until the end, dragging out talks.

‘Victory for multilateralism’

UN Secretary-General Antonio Guterres commended the delegates, according to a spokesperson, who said the agreement was a “victory for multilateralism and for global efforts to counter the destructive trends facing ocean health, now and for generations to come”.

“It is crucial for addressing the triple planetary crisis of climate change, biodiversity loss, and pollution,” a UN statement said.
Greenpeace says 11 million square km (4.2 million square miles) of ocean needs to be put under protection every year until 2030 to meet the target.

“Countries must formally adopt the treaty and ratify it as quickly as possible to bring it into force, and then deliver the fully protected ocean sanctuaries our planet needs,” said Laura Meller, a Greenpeace oceans campaigner who attended the talks. “The clock is still ticking to deliver 30 by 30. We have half a decade left and can’t be complacent,” she added.
