What is happening with the Jackdaw and Rosebank gas and oil fields?
Jackdaw Gets Green Light as Rosebank Decision Remains Pending
Constantvpn.com – The UK has cleared the Jackdaw gas development in the North Sea to begin production, ending a lengthy period of court challenges and political dispute. A separate decision on Rosebank, a much larger proposed oil development west of Shetland, has still not been made.
The two projects have become central to the argument over Britain’s future energy strategy. Supporters see domestic production as a way to sustain employment and reduce exposure to imported fuel supplies. Opponents argue that approving further extraction is incompatible with efforts to limit the emissions driving more frequent heatwaves and destructive extreme weather.
Where are the projects?
Jackdaw lies roughly 150 miles, or 241km, east of Aberdeen. The government has said gas from the field could enter the system by the end of the month. Its offshore facilities include a production platform and drilling operation in the North Sea.
Rosebank is situated about 80 miles, or 128km, north-west of Shetland. It is regarded as the UK’s biggest undeveloped oil resource and would produce some gas alongside its oil output. If it receives approval, operations are intended to begin in 2027.
Although both schemes are often discussed together, their roles in the energy system would differ. Jackdaw is primarily a gas project with a comparatively direct connection to the UK network. Rosebank would produce a heavier form of crude oil, much of which would need to be processed overseas.
Why did the approvals return to government?
Licences for the developments were issued under the previous Conservative government, in 2022 and 2023. Environmental organisations subsequently brought legal cases challenging those decisions.
Last year, the Court of Session in Edinburgh found that the approvals for Jackdaw and Rosebank had been unlawful because the government had not properly considered the climate consequences of burning the oil and gas extracted from the fields. The ruling required more detailed assessments of those downstream emissions.
Revised climate estimates were then published for consultation. The government was required to consider the projects again, taking account of input from industry regulators. Prime Minister Andy Burnham had previously said that Labour would honour existing licences while declining to issue new oil and gas licences.
Jackdaw has now passed that renewed approval process. Rosebank remains with the regulator and has not yet been sent to the energy secretary for a final decision.
What could Jackdaw provide?
When the development was announced in 2022, its backers said the field could generate enough gas to meet the needs of 1.4 million homes. Because it can be linked relatively easily to Britain’s energy infrastructure, gas can be brought ashore without the longer timetable associated with a more complex new oil development.
At maximum output, Jackdaw is expected to lift UK gas production by about 6%. Over an estimated 11-year operating life, the government says the scheme could retain hundreds of jobs and contribute around £2.9bn to the economy.
Those points sit at the heart of the case made by the industry: domestic supply may offer practical support to offshore workers and related businesses while international conflicts continue to create uncertainty around global energy supplies.
Why would Rosebank not automatically cut bills?
Rosebank is projected to yield as many as 500 million barrels of oil across a 25-year lifespan. Even so, a larger domestic supply does not guarantee lower household energy costs. Oil and gas prices are set in international markets, where major disruptions can affect prices across many countries.
The war in Ukraine and tensions involving Iran illustrate how global events can rapidly influence fuel costs. The UK would still need to import oil and gas even if both North Sea projects operate, leaving consumers exposed to movements in world markets.
Rosebank’s oil presents an additional complication. Britain’s remaining refineries are not designed to process the heavier crude expected from the field. Most of it would therefore be exported to the Netherlands. If products made from that crude, including diesel or aviation fuel, were needed in the UK, they could later be brought back into the country as imports.
Fatih Birol, the International Energy Agency’s executive director, has questioned whether additional North Sea drilling would materially alter Britain’s energy position.
“would not change much for the UK's energy security”
He also argued that new drilling would not reduce energy bills because prices would continue to be set internationally.
Emissions remain the central dispute
Both fields are operated by Adura, a joint venture involving Equinor of Norway and Shell. Aberdeen-based Ithaca Energy holds a 20% stake in Rosebank.
Jackdaw’s lifetime emissions have been a particular point of disagreement. Ithaca estimated that the field could be responsible for 35.8 million tonnes of carbon emissions over its operating life, a figure comparable with 90% of Scotland’s emissions in 2023. Adura has put forward a lower estimate of about 23.6 million tonnes, equivalent to 60% of that annual Scottish total.
The projected emissions associated with Rosebank are far greater, approaching 250 million tonnes of planet-warming pollution. For campaigners, that scale makes approval difficult to reconcile with national climate goals. They contend that speeding up investment in cleaner technologies would offer a more durable route to energy security and employment.
For ministers, regulators and communities connected to the North Sea industry, the unresolved Rosebank decision will test how existing fossil-fuel licences are balanced against legal climate obligations, jobs and the UK’s continuing dependence on global energy markets.
