For years, Britain’s elites told us that Net Zero was destiny ,the moral, financial and technological path to prosperity.
Banks would fund it, unions would defend it, and engineers would deliver it.
That story ended on 3 October 2025, when the Net Zero Banking Alliance , the crown jewel of Mark Carney’s green-finance empire ,voted to wind down its operations and retreat into “guidance-only” status.
The City that once promised to save the planet has quietly admitted it can’t even save its own balance sheet.
The Green Bubble didn’t burst all at once. But that day marked the rupture that exposed the truth: Britain’s Net Zero project is collapsing from every direction,finance, labour, engineering and politics.
1 | Finance Walks Away — Carney’s Collapse
Mark Carney’s Net Zero Banking Alliance (NZBA) was launched in 2021 with fanfare. Over 130 major banks, controlling 40 per cent of global assets, pledged to “align portfolios with 1.5°C.”By 2025, it was in retreat. Returns from green-finance funds have lagged global indices for three straight years;
billions have left ESG products; and legal departments are warning that political targets breach fiduciary duty.
On 3 October 2025, members voted to suspend operational work indefinitely.
Carney’s flagship venture ,once hailed as the moral compass of capitalism , became an empty shell.
The symbolism is stark:
when ideology collides with risk management, ideology loses.The City’s message is clear: decarbonisation by decree is bad business.
2 | The Workers Revolt. Unite Says “Ditch Net Zero”While financiers retreat, the workers are rebelling.
Britain’s largest private-sector union, Unite, has demanded that Labour “ditch Net Zero” unless it protects domestic jobs.General Secretary Sharon Graham told reporters: “My members have no problem with Net Zero — but it must be a workers’ transition.”Under the current plan it isn’t. Green policy has become deindustrialisation in disguise:
shuttered steelworks, unaffordable power, and foreign supply chains taking the jobs Britain used to own.
For decades, Net Zero was sold as the Left’s crusade. Now the Left’s biggest union calls it a betrayal.When workers and financiers walk away in the same week, the consensus has already cracked.
3 | The Grid Groans — Europe’s Warning
In April 2025, Spain and Portugal suffered Europe’s worst blackout in twenty years.The culprit? Cascading overvoltages — too much renewable power flooding the grid without enough baseload to stabilise it.
ENTSO-E, Europe’s grid authority, called it “new territory.”Translation: too much wind and solar, not enough physics.Britain’s own grid faces the same fragility. National Grid ESO has issued repeated “high-voltage” alerts during low-demand weekends, paying wind farms millions to switch off while importing steady power from gas and nuclear.We are approaching the same cliff edge Spain went over — only pretending it’s progress.
4 | Politics in Disarray
At Westminster the contradictions multiply.
Energy Secretary Ed Miliband wants to link wind-farm subsidies to trade-union charters — effectively pricing politics into electricity bills.
Meanwhile the Treasury is alarmed by the £60 billion-plus cost of grid reinforcements to connect stranded renewable projects.And in a quiet admission of failure, the Government is reviving nuclear — naming six decommissioned sites for new reactors, including Wylfa, Oldbury and Hartlepool.
They know what they cannot say: without nuclear baseload, Net Zero collapses.
5 | The Great Unravelling
By autumn 2025 the pattern is undeniable:
Finance has left the room.Labour has lost faith.The grid is breaking.Politics is eating itself.
Carney’s collapse on 3 October is not an isolated failure; it’s the signal flare of a broader truth — the Net Zero edifice was built on borrowed money, imported hardware and wishful thinking.The cracks are now fault lines, and through them we glimpse the gaping hole ahead.
6 | The Reckoning and the Way Out
Britain must choose:
keep pouring billions into an ideological sinkhole, or rebuild an energy system grounded in engineering and sovereignty.
That means:
Fast-tracking Rolls-Royce SMRs on existing nuclear sites.Upgrading the AC grid before chasing fantasy hydrogen schemes.Backing domestic manufacturing instead of subsidising imports.Replacing carbon-target law with an energy-security law that puts reliability first.
7 | Closing Word 3 October 2025 will be remembered as the day the Green Bubble finally burst.
When the financiers walked, the unions revolted, and the engineers warned, the illusion could no longer hold.What comes next is not the end of progress — it’s the return of reality.
