Climate activists won a court case in Norway against the state over development plans at a handful of oil and gas fields under the sea off the Nordic country’s coast.

Greenpeace Norway and Young Friends of the Earth argued that development plans at the Breidablikk, Tyrving and Yggdrasil fields, approved by the ministry of energy in 2021 and 2023, are invalid. On Thursday, the Oslo District Court concluded that the impact of combustion emissions must be considered by law, and that no impact assessment of such emissions had been carried out in connection with the decisions in question, it said.
