Two decisions now approaching the final stage could have consequences far beyond the oil and gas industry.
Public consultations on the Jackdaw and Rosebank North Sea developments are reaching their deadlines, reopening one of the biggest economic arguments facing Scotland: how quickly should the North Sea oil and gas industry decline, and what happens to the thousands of skilled jobs and businesses that currently depend upon it?.
The Jackdaw consultation closes 10 August, while the Rosebank consultation closes 17 August. Both are part of the revised environmental consent process following court rulings that required the projects' assessments to take account of emissions from the eventual use of the oil and gas produced.
These are therefore much more than two planning exercises.
They are a test of Britain's future energy and industrial policy.
Why Rosebank matters
Rosebank, located west of Shetland, is the larger of the two developments.
Equinor estimates that the project represents around £8.5 billion of investment, with approximately £6.6 billion expected to be spent in the UK economy.
Its environmental submission estimates that Rosebank could generate around £25 billion of GVA over its lifetime.
At peak production, annual GVA is estimated at about £2 billion, equivalent to almost 1% of Scottish GDP.
The project is also expected to generate significant activity for the supply chain, with Equinor already working with hundreds of suppliers around the UK.
Those numbers explain why the project has attracted such strong support from parts of the Scottish business community.
But they are estimates, not guaranteed economic benefits.
The amount actually captured by Scotland will depend on how much work goes to Scottish companies rather than suppliers elsewhere in Britain or overseas.
Jackdaw is different
Jackdaw is primarily a gas development, located around 150 miles east of Aberdeen.
Its importance is therefore not simply about jobs.
The field could supply around 6.5% of UK Continental Shelf gas at peak production, with the gas entering the National Gas transmission system through St Fergus.
That makes Jackdaw particularly interesting for Scotland.
The St Fergus terminal and the wider gas infrastructure around the north-east have been important parts of Britain's energy system for decades.
Keeping that infrastructure active matters because Britain's North Sea production is declining while the country continues to consume substantial quantities of gas.
How many jobs are really at stake?
This is where the debate becomes complicated.
Industry estimates suggest that Rosebank and Jackdaw together could support around 3,500 jobs at peak construction, with approximately 880 jobs sustained during production across communities in the UK.
The developers also estimate that the two projects together could generate more than £28 billion of GVA over their lifetimes.
But those figures need to be understood carefully.
Jackdaw itself is highly automated.
Documents submitted to the regulator indicate that only 27 additional direct full-time jobs are specifically associated with the Jackdaw installation, while wider employment associated with the project is much larger because it includes supply-chain and existing offshore jobs.
That distinction matters.
The argument for these projects is not that thousands of people will suddenly be employed directly on two new platforms.
The argument is that major projects keep an entire industrial ecosystem working.
That includes engineers, fabricators, electricians, welders, surveyors, marine companies, helicopter operators, accountants, consultants, equipment manufacturers, logistics companies and professional services.
And that is where Scotland is particularly exposed
Scotland has an enormous amount of expertise built up around offshore energy.
The Offshore Energies UK industry estimates that Scotland's wider offshore energy sector supports approximately 128,400 jobs and contributed around £24 billion to the Scottish economy in 2024.
Oil and gas is only part of that figure.
The same companies and workers are increasingly involved in offshore wind, subsea engineering, carbon capture, hydrogen and other emerging technologies.
This is why the argument cannot simply be reduced to oil versus renewables.
The real economic question is whether Scotland can maintain the skilled workforce and supply chains that will be needed for the next generation of offshore energy.
What happens if the projects disappear?
This is perhaps the most important question.
If North Sea oil and gas projects decline more quickly than new offshore industries develop, Scotland could experience a period in which skilled workers leave the sector faster than renewable industries can absorb them.
That is not simply an Aberdeen problem.
The economic supply chain stretches across Scotland and into the Highlands and Islands.
A specialist engineering company may have contracts in Aberdeen, Shetland, Caithness and elsewhere.
A marine business may service several different industries.
A fabrication company may move from oil and gas work into offshore wind.
A highly skilled engineer can work across multiple energy technologies.
If the work disappears, however, the skills themselves can eventually disappear.
And once skilled workers have left Scotland, they are not necessarily easy to bring back.
What could this mean for Highland?
The Highland economy has a particularly interesting connection to the North Sea energy industry.
The region does not have the concentration of oil companies found in Aberdeen, but it has businesses and workers connected to engineering, marine services, ports, transport, construction and energy infrastructure.
There is also a much bigger opportunity emerging.
The Highlands and Islands are becoming increasingly important to offshore wind and electricity infrastructure.
That means the same workforce could potentially move from one part of the energy economy to another.
But that transition takes time.
A worker cannot necessarily move directly from maintaining an oil installation to manufacturing an offshore wind turbine.
Companies need contracts, investment and certainty before they can make that transition.
Energy security is another part of the argument
Jackdaw's gas is particularly relevant because Britain still needs gas.
The UK can reduce its use of fossil fuels, but it cannot eliminate them overnight.
If domestic production falls faster than consumption, Britain becomes increasingly dependent on imports.
That means buying gas from international markets and transporting it into Britain.
The argument from supporters of Jackdaw is therefore that producing some of the gas Britain will need domestically can provide greater security and retain economic activity within the country.
Critics counter that the projects will not determine household energy bills because oil and gas are traded in international markets.
That criticism is important.
Rosebank and Jackdaw will not suddenly make petrol or household gas dramatically cheaper.
Their economic significance is much broader: production, investment, supply chains, taxation and energy security.
And then there is the tax question
The Treasury also has an interest.
The UK oil and gas industry has historically generated substantial tax revenues, although the amount received varies dramatically according to oil and gas prices, production levels, investment allowances and the tax regime.
The developers of Jackdaw and Rosebank argue that the projects could generate significant additional tax receipts.
But again, these should be treated as estimates rather than guaranteed windfalls.
The economics of North Sea projects have become much more complicated because development costs are high and the tax regime has changed substantially.
The real choice facing Scotland
This is why the Rosebank and Jackdaw consultations matter so much.
The debate should not be:
"Do we want oil and gas or do we want renewables?"
Scotland needs to think about both.
The North Sea oil and gas industry is declining.
That is a reality.
But the decline does not necessarily have to mean the disappearance of Scotland's offshore energy industry.
The opportunity is to use the existing workforce, companies, ports, engineering expertise and infrastructure to build the next generation of energy industries.
That requires investment in offshore wind, electricity transmission, hydrogen, carbon capture and other technologies at the same time as managing the decline of oil and gas.
The danger of getting the timing wrong
There is a genuine economic risk on both sides.
Move too slowly away from fossil fuels and Scotland risks missing climate targets and investing in assets with shorter economic lives.
Move too quickly and the country could lose skilled workers and companies before replacement industries are ready.
That is the difficult balancing act facing the UK and Scottish Governments.
For Aberdeen it could determine whether the city remains one of Europe's great energy centres.
For the Highlands, it could determine whether the region captures some of the enormous investment now being planned in offshore energy — or simply watches the jobs and contracts go elsewhere.
These decisions are bigger than two oilfields
Rosebank and Jackdaw will not determine the future of Scotland's energy industry by themselves.
But they are symbolic of a much bigger decision.
Does Scotland allow its existing offshore energy industry to decline first and hope that the renewable economy replaces it later — or does it deliberately use today's oil and gas expertise, companies and workers as the bridge into tomorrow's energy economy?
That may ultimately be the most important economic question raised by these two consultations.
The answer will affect far more than the oil industry.
It could determine the future of thousands of Scottish jobs, hundreds of supply-chain companies and the economic future of communities from Aberdeen to Shetland — and potentially into the Highlands as well.
