What We Know About the Rosebank Oil Field Decision

Rosebank is an undeveloped oil field roughly 80 miles northwest of Shetland, and a decision on whether to let it start producing is expected from the UK government within weeks, according to BBC News. If approved, oil and gas would be pumped up through a large ship stationed above the field. Energy Secretary Miatta Fahnbulleh holds the formal power to decide, and she has called affordability of energy bills her "overriding objective," the BBC reported. Prime Minister Andy Burnham said Wednesday only that a decision would be "taken in due course."

Why are Labour MPs divided over Rosebank?

More than a dozen Labour MPs raised concerns about approving Rosebank during a Westminster Hall debate this week, the BBC reported, arguing the field is "incompatible" with the UK's climate commitments. Separately, more than 60 of Labour's roughly 400 MPs have indicated support for a backbench letter opposing Rosebank that has been drafted for Burnham but not yet sent, according to the BBC.

One signatory told the BBC that approving Rosebank "would not create new jobs, would bring minimal money into the Treasury and be bad for the climate," adding that "the government's central aim is to tackle the cost of living crisis, and drilling for more oil at Rosebank isn't the answer." Sheffield Central MP Abtisam Mohamed told the debate that "Rosebank fails on every test," arguing it "will not benefit taxpayers who will shoulder the vast majority of the development costs," will not strengthen energy security because "most of the oil will be sold on international markets," and will not lower bills because constituents "will remain exposed to volatile fossil fuel prices," per the BBC. Former frontbencher Richard Burgon said Rosebank "is not compatible with our climate targets" and that it is "dangerous to pretend otherwise."

Other Labour MPs back approval. Supportive lawmakers pointed to economic benefits and noted that some other parts of the world emit far more greenhouse gases than the UK, warning against relying on imported oil instead, the BBC reported. Chancellor John Healey is reported to favor approval, according to the BBC.

Who actually makes the final call on Rosebank?

The UK government has consistently described Rosebank as a quasi-judicial decision resting formally with the energy secretary, Fahnbulleh, rather than with the cabinet or Parliament as a whole, the BBC reported. She already approved production at the Jackdaw gas field in the North Sea last month, giving some indication of her approach, though Rosebank remains undecided.

What happened in court that forced a new decision?

Rosebank and Jackdaw were originally licensed by the previous Conservative government in 2023 and 2022, respectively, according to the BBC. The Court of Session in Edinburgh ruled last year that those approvals had been granted unlawfully, which left the current Labour government needing to make fresh decisions on whether to give both fields the go-ahead. Jackdaw has since cleared that fresh review; Rosebank has not.

How does this fit with Labour's 2024 manifesto pledge?

Labour's manifesto when it entered power in 2024 pledged not to "issue new licences to explore new fields," the BBC reported. Because Rosebank's licence predates that government and is being reconsidered only because of the court ruling, ministers have treated it as a legacy approval decision rather than a new licence — a distinction that underpins the government's case for potentially approving it despite the manifesto language, even as critics argue the practical climate effect is the same.

The UK is committed to reaching net zero emissions by 2050 and to limiting global warming to no more than 1.5C above pre-industrial levels, targets that opponents of Rosebank cite directly in their objections, per the BBC.

What to watch next

• Whether Fahnbulleh's formal decision, described by the BBC as expected "in the coming weeks," approves, rejects, or imposes conditions on Rosebank.
• Whether the backbench letter — currently backed by more than 60 Labour MPs, according to the BBC — is formally sent to Burnham before a decision is announced.
• Any additional public statements from Healey, Burnham, or Fahnbulleh clarifying the economic or climate reasoning behind the eventual call.
• Reaction from Conservative leader Kemi Badenoch, who the BBC reported has already sought to highlight divisions inside Labour over the issue.
• Whether the Rosebank outcome is challenged again in court, given that the Court of Session's prior ruling is what reopened the decision in the first place.

For now, the record shows a governing party publicly split between MPs citing climate targets and Treasury returns on one side, and MPs citing energy security and economic benefit on the other — with the deciding vote, in effect, belonging to one Cabinet minister rather than to Parliament.
