Scotland's North Sea oil and gas industry faces another crucial period, with the future of major offshore developments caught between the need to secure energy supplies, protect industrial jobs and meet the UK's climate commitments.
At the centre of the debate are the Rosebank oilfield and the Jackdaw gasfield, both off the coast of Scotland. The projects have become symbols of a much wider argument about the future of the North Sea: should the UK encourage new domestic production, or concentrate its efforts on moving away from fossil fuels as quickly as possible?
The stakes are considerable. The oil and gas industry supports a network of engineering companies, specialist contractors, equipment suppliers and other businesses, many of them based in Scotland. A decision affecting offshore development can therefore have consequences far beyond the platforms themselves.
But the economic argument is more complicated than simply counting the barrels of oil or quantities of gas that could be produced.
Why Rosebank and Jackdaw matter
Rosebank is a major undeveloped oilfield west of Shetland, while Jackdaw is a gas development in the central North Sea.
Their original approvals were challenged because the environmental assessments had not properly accounted for the emissions created when the extracted oil and gas were eventually burned.
Following legal proceedings, the original consents were quashed. Any fresh decision must take account of the wider climate impact, rather than examining only emissions generated directly by constructing and operating the installations.
That distinction is important. Producing oil and gas involves emissions from extraction and processing, but burning those fuels also releases greenhouse gases. The environmental assessment must consider the wider consequences.
The UK Government now faces the challenge of deciding how the projects should be treated under the applicable legal and climate framework. Their future has become an important test of how ministers balance energy security, investment and environmental obligations.
Will new production lower energy bills?
One of the strongest arguments made by supporters of new North Sea development is that domestic production can help protect the UK's energy security.
The UK continues to use oil and gas, and domestic production can reduce the amount that must be imported. It can also sustain work for engineers, technicians, offshore workers and the businesses that supply them.
However, there is an important qualification: more oil and gas produced in British waters does not automatically mean lower prices for British households or businesses.
Oil is traded in international markets, and prices are influenced by global supply, demand, geopolitical tensions and shipping disruptions. Gas prices are also affected by international markets and the UK's wider supply arrangements.
New production could contribute to domestic supply, but it would not insulate the UK from a global price shock. Nor would the approval of a new field necessarily produce an immediate increase in available supply.
That matters when assessing claims that approving Rosebank or Jackdaw would directly reduce petrol prices, diesel costs or household energy bills.
Energy security is a legitimate objective, but it should not be confused with a guarantee of cheaper energy.
The jobs argument is more complicated
The North Sea industry provides highly skilled employment and supports specialist companies whose expertise has been developed over decades.
Those skills are valuable, particularly as Scotland seeks to expand offshore wind, electricity infrastructure and other energy technologies. The same engineering knowledge, offshore experience and project-management capability may be relevant across different parts of the energy sector.
Supporters of continued oil and gas development argue that new projects would help sustain this industrial base and provide work while the transition to lower-carbon energy takes place.
Opponents question whether approving new fields provides the best long-term protection for employment. They argue that projects with limited operating work may create a burst of construction activity without securing equivalent permanent employment, while investment could be diverted from industries expected to grow as the energy system changes.
Both arguments deserve examination. A large project value does not tell us how many jobs will be created, how long they will last or how much work will go to Scottish suppliers.
Those questions require detailed evidence about construction employment, permanent staffing, contracts, wages and the proportion of expenditure retained in Scotland.
What about the supply chain in the Highlands?
For the Highlands and Islands, the future of the North Sea matters because of the links between offshore energy and local engineering, maintenance and logistics businesses.
Aberdeen remains a major centre for the industry, but the wider supply chain extends across Scotland. Companies in smaller communities can depend on contracts won from major operators and their principal contractors.
A sudden contraction in offshore work could therefore have consequences for businesses that have invested in specialist equipment and training.
However, the answer cannot simply be to preserve every existing activity indefinitely. Businesses need confidence that demand will remain strong enough to justify investment, and workers need realistic opportunities to transfer their skills into new areas.
That requires a managed transition, with training linked to actual employment opportunities and a credible pipeline of projects.
For Caithness and Sutherland, the wider lesson is that energy policy should be judged partly by the industrial opportunities it creates locally. It is not enough to announce a national investment if the resulting jobs and contracts are concentrated elsewhere.
The climate question cannot be ignored
The case against new oil and gas development is not confined to opposition to fossil fuels in principle.
The UK has climate commitments, and the emissions associated with new developments must be assessed against those obligations. There are also questions about whether long-lived infrastructure could become less commercially attractive as demand changes and lower-carbon alternatives expand.
Investors must consider the risk that projects approved today could face a different market in the years ahead. Government policy, international climate action and changing energy technology can all influence the commercial life of an asset.
At the same time, the UK cannot instantly eliminate its demand for oil and gas. The transition must account for the needs of households, industry, transport and electricity generation, as well as the reliability and affordability of alternative supplies.
The difficult question is how to manage that dependence while avoiding unnecessary long-term commitments to fossil fuels.
Scotland needs more than a choice between two extremes
The debate is often presented as a simple choice between protecting North Sea jobs and tackling climate change. In practice, Scotland needs a plan that addresses both.
That means being honest about the employment and tax revenues associated with oil and gas, while also recognising the risks of relying too heavily on a mature industry whose long-term direction is changing.
It means assessing individual projects on their legal, environmental and economic merits rather than assuming that every development is either essential or unacceptable.
It also means developing alternative sources of industrial employment before existing opportunities disappear. Offshore wind, grid infrastructure, engineering, decommissioning and other energy-related activities could provide work, but they require investment, skills and sustained demand.
The decision must stand up to scrutiny
Rosebank and Jackdaw are important because their future will signal how the UK intends to manage the competing demands of energy security, industrial employment and climate policy.
Approving a project would not guarantee lower energy bills or permanent jobs on the scale sometimes suggested. Rejecting one would not, by itself, create replacement employment for the workers and suppliers affected.
The Government therefore needs to explain clearly what each decision means for energy supplies, emissions, public revenues and jobs, including how many positions are temporary and how many are expected to last.
For Scotland, the objective should be to protect valuable industrial skills while building a broader energy economy capable of providing secure, skilled work in the decades ahead.
The real test is not simply whether more oil and gas can be extracted from the North Sea. It is whether Scotland can manage the transition in a way that protects workers and communities without losing sight of the environmental responsibilities that will shape the country's future.
