Norway's Supreme Court annuls three North Sea oil licenses over unassessed combustion emissions

The ruling

Norway's Supreme Court on Friday, 13 November 2026, declared three oil production licenses in the North Sea invalid. The judges found that the approvals had been reached through procedural defects, because the impact assessments covered only production emissions. The court confirmed the rulings of the two lower courts, which had already backed the two environmental groups that brought the case. Production is already under way at Breidablikk and Tyrving, and output from Yggdrasil is due to start in 2027. The court stressed that the ruling does not mean the licenses have automatically lost their validity for their holders, but the government must now re-examine them.

Why the court found the approvals defective

The court's statement said that emission assessments had been carried out, but they concerned only what is called production emissions. The later combustion emissions, produced when the extracted oil is burned, were not covered. The court put the requirement this way in its note:

“emissions from the combustion of extracted oil must be subjected to an impact assessment”

Oil companies were not parties to the proceedings, which is why the ruling does not strip them of their rights on its own. The statement added that a majority of six of the 11 judges considered the impact studies and the authorities' assessments insufficient. The Supreme Court sat in plenary session with 11 judges instead of the usual five, a format reserved for cases of particular importance.

Case history

The case began in 2023, when Natur og Ungdom and the Norwegian branch of Greenpeace challenged the licenses for the Tyrving, Breidablikk and Yggdrasil fields. The groups argued that the licenses had been granted before environmental impact studies were carried out. The Norwegian government had allowed development of the fields despite the lawsuits. A first-instance court sided with the groups in January 2024, prompting the Ministry of Energy to appeal. An appeal court upheld that decision in November 2025, and the government then took the matter to the Supreme Court.

Reaction and what happens next

Haldis Tjeldflaat Helle, head of the Norwegian section of Greenpeace, commented to AFP shortly after the ruling was announced. She called it a victory in the following words:

“It is a historic victory for the climate and for Norwegian democracy”

Helle also said that large emitters would now have to declare how much they contribute to the climate crisis. The Norwegian government did not respond to an AFP request for comment at first. The Ministry of Energy is now responsible for re-examining the three licenses. Legal experts and nongovernmental organizations challenging oil and gas licenses are expected to analyse how far the decision reaches. Litigation of this kind has been gaining prominence worldwide.
