The groundbreaking advisory opinion was unanimous, and consultants say it might result in extra wide-ranging claims for damages towards polluting nations.
The opinion by the court docket, the International Tribunal for the Law of the Sea, will not be binding, but it surely mentioned that, legally, nations should take all needed measures to cut back, management and forestall marine air pollution brought on by human-made greenhouse gasoline emissions.
The stance taken by the tribunal, which is usually known as the Oceans Court docket, is prone to have an effect on how different worldwide and nationwide courts tackle the rising risks posed by greenhouse gases that trigger the heating and acidification of the oceans.
Because the world warms, the oceans are absorbing a big quantity of the surplus warmth, which has the potential to alter ocean currents and the marine ecosystem and contribute to coral bleaching, amongst different risks. Acidification, which can be harmful to sea life and may alter marine meals webs, occurs as ocean waters soak up carbon dioxide, the principle greenhouse gasoline warming the world.

The opinion issued by the 21 judges on Tuesday successfully expanded the definition of marine air pollution to incorporate greenhouse gases. The conference, which was negotiated within the Nineteen Seventies, doesn’t point out these emissions and their antagonistic results on the world’s oceans, that are primarily based on newer science.
“We didn’t understand how critical these emissions had been within the Nineteen Seventies,” mentioned David Freestone, the co-author of a 2023 World Bank report on the authorized dimension of sea degree rise who has adopted the hearings and debates on the court docket. “At the moment, individuals had been involved about acid rain.”
Key questions addressed by the court docket included whether or not extreme greenhouse gasses represent “air pollution of the marine atmosphere” and, in that case, whether or not international locations will be held to account for that air pollution. The judges mentioned sure in each circumstances.
Leaders of the island nations that introduced the case argue that current local weather accords haven’t made sufficient progress to forestall lasting injury to the oceans. They are saying that whereas they contribute solely a small fraction of worldwide emissions, they’re already bearing the brunt of catastrophic results of the altering local weather.
“That is actually an epic David and Goliath contest,” Payam Akhavan, the lead lawyer for the group that introduced the case, mentioned at a latest information briefing. He mentioned that a few of the world’s smallest nations had been invoking the ability of worldwide legislation towards main polluters.
China and Saudi Arabia, a significant oil exporter, strongly challenged the islands’ request throughout final yr’s hearings within the case, saying that the court docket lacked ample authority to set out new guidelines. However on Tuesday, the judges mentioned the court docket did have jurisdiction.
