UK Energy Secretary Greenlights Jackdaw Gas Field, Leans Toward Rejecting Rosebank Oilfield

UK Energy Secretary Miatta Fahnbulleh officially approved the development of the Jackdaw gas field on October 21, 2026, a project projected to boost the nation's domestic gas production by approximately 6% at its peak[1][3][14]. Concurrently, Fahnbulleh is reportedly "leaning towards rejecting" the Rosebank oilfield, which is described as Britain's largest untapped oil field[6][8][10].

This diverging approach to two significant North Sea energy projects highlights the government's complex task of balancing energy security and economic benefits with its climate commitments. The decisions carry implications for the UK's energy independence, its economy, and its progress toward net-zero emissions[1][4][9].

What the records show

On October 21, 2026, the North Sea Transition Authority (NSTA) granted final development and production consent for the Jackdaw gas field, following Energy Secretary Fahnbulleh's agreement to an updated Environmental Statement[2][3][5][14]. Operated by Adura, a joint venture between Shell and Equinor, the project is expected to begin supplying gas to British homes and businesses by the end of October 2026[1][4][5]. The government anticipates Jackdaw will operate for up to 11 years, adding an estimated £2.9 billion to the UK economy and representing a £2.1 billion opportunity for the North Sea supply chain, securing hundreds of jobs[4][9][14].

In contrast, reports from The Guardian and other outlets indicate that Fahnbulleh is "minded to reject" the Rosebank oilfield[8][10][11]. Rosebank, located approximately 80 miles northwest of Shetland, is significantly larger and described as one of the biggest untapped oil fields in the North Sea[6][8]. Fahnbulleh differentiated the two projects, stating to The Guardian, "One is a gasfield that caters for the domestic market, while the other is an oilfield that is mainly for export"[8][10]. Reports also suggest Rosebank's carbon emissions are about seven times higher than Jackdaw's, though these figures have not been independently verified[11].

The timeline of approvals

The original development consent for Jackdaw was signed in 2022 by the previous Conservative administration[2]. However, a judicial review in approximately January 2025 led to the suspension of Jackdaw's consent and voided permits for Rosebank, citing insufficient assessment of "Scope 3 emissions," which are emissions from burning the extracted oil and gas[2][9]. This required Adura to reapply for new licenses for Jackdaw[9]. The Labour Party's 2024 election manifesto included a pledge against issuing new licenses for North Sea oil and gas exploration[4][9].

What changed and for whom

The re-approval of Jackdaw provides a boost to the UK's domestic gas supply and the North Sea energy industry, protecting jobs and contributing to the economy[4][9][14]. Energy Secretary Fahnbulleh defended the decision, stating domestic production would strengthen energy security and reduce reliance on imported fuels[9][13]. Concurrently with Jackdaw's approval, the government announced a new Energy Wealth Fund, starting with an initial £2 billion investment to channel future North Sea oil and gas tax revenues into renewable and low-carbon energy projects[14]. Environmental groups have criticized the Jackdaw approval, expressing serious concerns about its climate impact[4][9]. Industry and the Conservative Party have urged the government to approve Rosebank, citing economic benefits and energy security[12].

What the Secretary has said publicly

Energy Secretary Miatta Fahnbulleh has affirmed her sole authority over the Rosebank decision, noting a "tight" regulatory framework designed to withstand court scrutiny[6]. She reiterated that each application must be judged on its own merits and remain consistent with the UK's climate obligations and net-zero path[8][9][10]. On October 23, 2026, Prime Minister Andy Burnham stated that the decision on Rosebank would be "done properly," emphasizing the careful consideration given to Jackdaw's approval[7].

What we could not confirm

The exact timeframe for a final decision on the Rosebank oilfield could not be confirmed. Whether Prime Minister Andy Burnham or Chancellor John Healey could overrule Energy Secretary Fahnbulleh's decision on Rosebank also remains unconfirmed[10][11]. Independent verification of the reported carbon emission differences between Rosebank and Jackdaw was not available[11].
