Ithaca Energy is a pure-play North Sea oil and gas operator with minimal climate action. Scope 3 emissions—orders of magnitude larger than reported Scope 1 and 2—remain unquantified. The company faces a January 2025 court ruling invalidating Rosebank's consent and active NGO campaigns characterizing it as expansion-focused with no transition intent.

How is Ithaca Energy's SINK score calculated?
Same ten questions for every company. No private weighting.
SINK = (0.3 × Base + 0.7 × Performance) × ScaleWhat evidence is Ithaca Energy's score based on?
10 sources used in this assessment. All publicly available. Each row shows which of the ten questions it informed.
60% of them were published by Ithaca Energy itself; the rest come from independent sources.
Ithaca Energy reports the emissions from running its own operations, but does not disclose the emissions from burning the oil and gas it sells. For a hydrocarbon producer that is the larger part of the footprint by a wide margin — typically the great majority of it. This score is calculated on the conservative basis the methodology applies when the dominant category is absent, and the absence itself is part of the finding. It is not an estimate of undisclosed emissions, and it would change if the company published them.
“gross operated absolute Scope 1 and 2 emissions have increased to 448,190 tCO2e in 2024 (2023: 435,792 tCO2e)”
“Environmental performance data for each of our operated assets is submitted to the UK environmental regulator (OPRED) via the Environmental Emissions Monitoring System (EEMS)”
“On 30 January 2025, the Court of Session ruled that consent had been unlawfully given in relation to the sanctioning of the Rosebank field development and that a new consent application would be required which included Scope 3 emissions”
“Our focus today, and in the near term, is to deliver emissions reduction projects as set out in our asset ERAPs.”
“Centralise environmental data collection post Business Combination”
“number of reportable releases to sea (spills) fell by circa 70% in H1 2025, in comparison to H1 2024”
“Chemical use and discharge is strictly regulated and a permit is required before any use or discharge to sea”
“Ithaca Energy is a 'pure play' fossil fuel company that is dedicated to expansion and has no intention of transitioning away from oil and gas.”
“Court rules Rosebank and Jackdaw approvals invalid”
“Over 80 organisations have written to the CEOs of 12 major banks, calling on them to stop financing Ithaca if it continues to pursue its Rosebank project.”
