[2024] UKSC 20
R (Finch on behalf of the Weald Action Group) v Surrey County Council
Supreme Court of the United Kingdom · 20 June 2024

- Court
- Supreme Court of the United Kingdom
- Decided
- 20 June 2024
- Citation
- [2024] UKSC 20
- Status
- Decided; since applied to Whitehaven, Rosebank and Jackdaw
What was decided
The UK Supreme Court held that Surrey County Council acted unlawfully when it approved an oil project at Horse Hill without assessing the climate impact of burning the oil the project would produce. Where burning a project’s product is inevitable and can be estimated, those emissions are an effect of the project and must be assessed.
Why it matters
Finch decides what must be assessed, not what must be decided. Before it, the climate section of an oil project’s assessment could cover a small fraction of the project’s footprint. Now the largest number has to be on the table when the decision is made, and the reasoning has since been applied to a coal mine in Cumbria and to oil and gas fields in the North Sea.
3–2Majority in the Supreme Court; all five justices agreed the question has one right answer
10.6 MtCO2 from burning the oil, as estimated in the council’s own evidence
140,958 tOn-site CO2 counted in the developer’s assessment, described as “negligible”
