Norway's Supreme Court ruled on Friday that the government's development approvals for three North Sea oil and gas fields are invalid, because the environmental assessments behind them did not adequately account for the climate impact of burning the oil and gas the fields will produce.

The judgment, in case HR-2026-2428-S, was carried by a majority of six judges to five, according to summaries of the ruling published on Friday. It covers Equinor's Breidablikk field and Aker BP's Tyrving field — both already producing — and Aker BP's Yggdrasil area, the largest of the three, which is under development and scheduled to come on stream next year.

The case was brought by Greenpeace Nordic and the environmental organisation Nature and Youth (Young Friends of the Earth Norway) against the Norwegian state. Their argument was that the approvals were granted without assessing so-called Scope 3 emissions — the greenhouse gases released when the extracted oil and gas are ultimately burned by customers.

The court held that the assessment must also consider the cumulative combustion emissions associated with other existing and approved petroleum developments on the Norwegian continental shelf, and found the government's assessments deficient on procedural grounds.

Invalid approvals — but the oil keeps flowing

The Supreme Court was explicit that its ruling does not shut the fields down. The oil companies were not parties to the case, it said, so declaring the government approvals invalid does not automatically mean the companies' permits cease to apply, Reuters reported.

Instead, the government must now reconsider each of the three developments under the correct requirements and decide whether the permits can be reissued. Operations at Breidablikk and Tyrving were allowed to continue throughout the appeals process.

The Oslo District Court and the Borgarting Court of Appeal had both earlier ruled against the government in the same litigation, but likewise stopped short of halting production from the affected fields.

A climate test set during COP31

The ruling lands while delegates from around 200 nations are gathered in Antalya, Türkiye, for the COP31 climate conference, and it sharpens the long-running tension between Norway's position as one of the world's largest oil and gas exporters and its international climate commitments, The Guardian reported.

For energy markets, the immediate effect is limited — no supply is lost and no new production timetable has been set — but the judgment establishes that future Norwegian offshore approvals must count the full climate cost of the hydrocarbons they unlock, including emissions from burning them, before they can be considered lawful.

What happens next: Norway's energy ministry must redo the assessments for Breidablikk, Tyrving and Yggdrasil, this time including combustion and cumulative shelf emissions, and take fresh decisions on the permits. Environmental groups are expected to press for the same test to be applied across the shelf.
