The UK government has approved extraction at the Jackdaw gas field in the North Sea, despite acknowledging that this decision could make it harder for Britain to convince other countries to move away from fossil fuel production.

UK energy secretary Miatta Fahnbulleh approved the drilling on Wednesday after months of high-profile debate, fuelled in part by interventions from US President Donald Trump. She argued that the project would boost energy security in the wake of the Middle East fossil fuel crisis, protect hundreds of jobs and add £2.9 billion ($3.88bn) to the UK economy.

She said Jackdaw’s gas would be cleaner than imported gas and would not prevent the UK from meeting its legally-binding carbon targets and its goal of net zero by 2050. As the field is already licensed, she said extraction was consistent with the Labour Party’s 2024 manifesto promise not to issue any new oil and gas licenses.

The same morning, the government announced a new Energy Wealth Fund to reinvest oil and gas revenues in the climate transition. It will start with £2 billion ($2.67bn) from the government and be topped up over time with tax revenues from offshore oil and gas production.

Climate campaigners in the UK and abroad were quick to condemn the decision, while a leading legal expert told Climate Home News it goes against the advice of the International Court of Justice. Meanwhile, the government’s own documents reveal that it recognises the drilling could damage the UK’s reputation and its ability to push forward the global transition away from fossil fuels.

“Climate leadership” blow

The 92-page decision document says Fahnbulleh “acknowledges that international standing on climate is important and accepts that a decision to grant consent may not further the UK’s international climate leadership.”

It adds: “She acknowledges concerns about the potential implications for the UK’s credibility and influence – including the difficulty inherent in encouraging other states to move away from fossil fuel production while the UK continues, in a limited and transitional way, to draw on its own domestic resources.”

While noting that Jackdaw has not been issued with a new license – just permission to extract gas – the document says Fahnbulleh “accepts this does not fully resolve the underlying tension in the UK’s position” but “considers this alongside the substance of the UK’s wider record [on emissions reduction], which remains significant”.

It continues that she accepts these concerns are “legitimate” and weigh against approving gas extraction, but only gives this argument a “moderate negative weight” set against the benefits of gas production.

“Huge” wrong signal

In international climate talks, the UK has long supported the transition away from fossil fuels and is one of very few major oil and gas producers to ban new licenses. Across the North Sea, the Norwegian government continues to make offshore areas available for oil and gas exploration through annual licensing rounds.

Climate experts and campaigners shared the concern, acknowledged in the decision document, that approving Jackdaw could set a precedent for fossil fuel production elsewhere. Sam Fankhauser, professor of climate change economics at Oxford University, said the direct climate impact of Jackdaw is “much smaller than the debate around it would suggest” but the “wrong signal it sends, however, is huge”.

Bob Ward, policy and communications director at the Grantham Research Institute on Climate Change, said that while Jackdaw’s output will be very small, “it will signal to other fossil fuel producers that they too should carry on with business as usual, less than a month before the COP31”.

Kenyan campaigner Mohamed Adow, director of Power Shift Africa, called the decision “a serious blow to Britain’s international climate credibility” as “the UK cannot expect developing countries to move away from fossil fuels while giving the green light to new drilling in its own backyard”.

International Court of Justice

In July 2025, the International Court of Justice (ICJ) advised that government failure to take appropriate climate action “including through fossil fuel production” may amount to an internationally wrongful act.

The UK voted in favour of a United Nations resolution welcoming the advisory opinion. Yet, in its Jackdaw decision document, it notes that the ICJ opinion is not legally binding and says the UK does not accept the court’s opinion that the customary international law duty to prevent significant harm to the environment applies to climate change.

Fahnbulleh concludes that, although it will have “significant effect on the environment”, gas drilling in Jackdaw “would not lead to significant harm to the environment” – and so does not breach any duty to prevent such harm. Instead, the government document says the duty should be considered “as a matter of policy rather than legal obligation”.

Margaretha Wewerinke-Singh, who led Vanuatu’s legal team pushing for the ICJ’s advisory opinion, told Climate Home News that treating the duty as a matter of policy rather than legal obligation is “not how international law works”. “An advisory opinion is not a judgement,” she said, “but it states the law as it stands, and that law binds the UK whether or not it accepts it.”

“Even as a matter of policy,” she added, “the decision asks the wrong question: whether Jackdaw on its own would cause significant harm. The Court found that accumulated emissions are already causing significant harm. What matters is whether approving new production is consistent with the stringent due diligence the duty requires.”

Public support for decision

While the decision was criticised by climate campaigners and the opposition Green party, polling reported by Politico suggests that 55% of British adults support drilling at Jackdaw, with just 14% opposed. Even supporters of the UK’s net zero target back new drilling by more than two to one, the polling found.

Jackdaw is one of two North Sea oil and gas fields the government has been debating whether to extract more from for months. While Jackdaw is a small gas field, the other, Rosebank, is a much larger field that holds mostly oil.

Rosebank’s emissions are estimated to be around seven times higher than Jackdaw’s. Fahnbulleh told Sky News that Rosebank is “different” to Jackdaw because its oil would be exported, whereas Jackdaw’s gas will be used in the UK, adding that she will consider it “in its own right”.

The Guardian reported on Wednesday that UK officials say Fahnbulleh is minded to refuse approval for Rosebank. She has not yet taken a final decision on Rosebank, the newspaper said, but a ruling is expected later this year.
