OSLO, Nov 13 — Norway’s Supreme Court on Friday ruled that three oil licences granted by the government in the North Sea were invalid since their emissions impact had not adequately been accounted for.

The court agreed with climate campaigners, who challenged the validity of the licences, arguing that the environmental impact assessments had not considered the emissions from burning the oil after it had been extracted.

The campaigners had already won victories in two lower-court rulings.

The high court ruled that the plans for extraction and expansion were “invalid due to procedural errors”.
