The UK government faces mounting pressure to make a decision on the approval of two major North Sea oil and gas projects, Jackdaw and Rosebank, amid concerns over energy security, economic investment, and emissions. Both fields are operated by Adura, a joint venture between Shell and Norwegian company Equinor, which have collectively invested nearly £11 billion in the developments.

The projects were initially approved by the previous Conservative government—Jackdaw in 2022 and Rosebank in 2023—but a court ruling last year invalidated these consents on the grounds that the government had not adequately assessed the environmental impact of the emissions involved. Since then, political indecision has delayed progress, with some attributing the stalemate to internal party considerations ahead of a recent by-election in Holborn & St Pancras.

Jackdaw, primarily a gas field, is smaller in scale with an expected production life of about ten years. It is projected to contribute approximately 6 percent of the UK’s gas supply and would emit around 0.8 percent of the country’s total emissions. Proponents argue that local gas production is preferable to reliance on imported liquefied natural gas (LNG) from the United States or supplies from Norway, both of which come with higher transport emissions and increased energy costs.

Rosebank, in contrast, is a substantially larger oil field expected to produce up to 69,000 barrels per day at peak output, with an operational timeline extending over several decades. The oil field’s emissions are anticipated to be much higher due to its nature as an oil-producing site, which has raised environmental concerns among critics of the project.

Anders Opedal, CEO of Equinor, has warned that failure to approve these projects would constitute a major setback for the UK’s attractiveness to investors in the energy sector, potentially making the country less investible. This viewpoint is echoed by other producers such as Ithaca Energy, which has recently expanded investment activities to Canada, citing the UK’s high tax regime as a deterrent. The current tax rates for North Sea production reach up to 78 percent, significantly above Canada’s corporate tax rate of 30 percent, prompting calls for fiscal reform to encourage continued investment.

Economic supporters of the projects highlight that the developments could create thousands of jobs—estimated at 3,500 during peak construction—and positively impact the UK’s balance of payments by reducing dependence on costly imports. Some experts also note that sustained domestic oil and gas production, combined with expansion of renewable energy, could contribute to a more balanced and secure energy mix in the UK.

At present, approval is pending with the government, led by Prime Minister Andy Burnham, who faces pressure to conclude the matter following the recent by-election. Energy Secretary Miatta Fahnbulleh is reportedly leaning toward sanctioning the Jackdaw project first, given its smaller size and potentially lower emissions impact, while the larger Rosebank project remains under closer scrutiny.

As the UK continues to rely on oil and gas for around 75 percent of its energy needs, the decision on whether to proceed with these projects will have significant implications for the country’s energy policy, investment climate, and environmental commitments moving forward.
