Here is a thought experiment that should worry every board. Take your P&L. Now add the true cost of the water you drew down, the soil you degraded, the emissions you released, the pollution someone else will eventually clean up, and the ecosystems you quietly consumed. Not a token carbon line. The full bill. For most companies, the profit disappears. For many, the whole business goes underwater.
That is not an activist claim. It is an accounting one. And it is the reason the next durable business model is not sustainable or circular — it is restorative, backed by an economic model that can finally put a number on what was free.
The profit is an accounting illusion
Externality is a polite word for someone else pays. For a century, the dominant business model has run on a convenient fiction: some costs could be treated as external. Pollution. Carbon. Depleted soil. Water stress. Biodiversity loss. Cleanup deferred to the public balance sheet. These costs never went away — they were simply left out of the accounts.
Leave enough cost out and any business looks profitable. The margin is not real; it is the gap between what the company actually consumed and what it bothered to count. When you add up the full material footprint — the water, biomass, soil, minerals and sinks behind everything a company sells — the true cost of operating is far larger than the reported one. Most business models look solvent only because they are undercounting the cost of their own inputs.
Put plainly: current business models are not profitable. They are subsidised — by nature, and by the future.
The subsidy is being withdrawn
That subsidy is now being priced back in, from several directions at once, and none of them is optional.
Regulation is closing the gap: carbon reporting, extended producer responsibility, disclosure requirements, litigation over historic harm. Insurance is closing it faster — insurers are not making a moral argument when they raise premiums, narrow coverage or exit a region; they are pricing exposure, forced to translate risk into money, which makes them the earliest warning system a business has. And measurement is closing it permanently: natural capital accounting exists precisely to move nature from scenery to balance sheet, from moral concern to economic constraint, from “free” to a line item with a number attached.
And now the process has an accelerant. For most of history, the reason externalities stayed external was simple: measuring them was slow, expensive and easy to contest. That excuse is expiring. AI removes the friction that protected the fiction. It can pull satellite imagery, supply-chain records, shipping data, sensor feeds, filings, certifications and public reporting into a single view and compare what a company claims against what it actually does — at a speed and cost no auditor could match. Where verifying a firm’s true footprint once took a regulator years, an agent can now assemble the picture in an afternoon. The gap between reported cost and real cost, which used to be too expensive to close, is becoming cheap to expose.
That changes the timeline, not just the tooling. Regulation is the intent, but AI is the enforcement mechanism it never had. A vague environmental claim survived as long as checking it was harder than making it. Reverse that ratio — make verification cheaper than the claim — and every unpriced liability becomes discoverable, comparable and, eventually, chargeable. Once the number exists, it cannot be un-seen. When a cost becomes visible, it becomes measurable, litigable, insurable, reportable and priceable. And a cost that can be priced eventually is priced — only now the “eventually” is measured in years, not decades.
This is a solvency question, not an ESG one
Reframe it as a balance sheet and the stakes change. A company that depends on water but has never priced its water risk is not being responsible or irresponsible — it is carrying an unrecognised liability. Same for the firm that depends on soil, pollinators, stable weather, cheap energy or long supply lines it has never mapped. Those dependencies are debts the accounts don’t show.
- Depleted soil and water are a liability the moment a regulator or an insurer puts a price on them.
- Deferred cleanup is a liability that transfers back the day the rules change.
- Stripped-down suppliers and burned-out people are capacity liabilities that come due as failure and cost.
A business whose real liabilities exceed its real assets has a name. It is insolvent — it just hasn’t been forced to file yet. The future brings the invoice.
Why the next model is restorative
If the linear, extractive model is structurally bankrupt once nature is priced, then reducing harm is not enough. Doing less damage still runs the account in one direction — it just slows the rate of loss. Sustainability buys time. It does not restore solvency.
A restorative model does. It is the only model whose economics improve as natural capital gets priced, because it runs the account the other way: it rebuilds the systems it draws on. Turn throughflow into round-flow — repair, refurbish, remanufacture, reuse, recover — and waste stops being a deferred cost and becomes an asset you already own. Restore soil, water, supplier health and workforce capacity, and you are not buying goodwill; you are building the one balance sheet that regulation, insurance and measurement are all now converging to reward.
The strategic logic is blunt: as nature moves onto the books, extractive models take on liabilities faster than they earn, and restorative models build assets faster than they spend. The crossover is not a values choice. It is arithmetic.
The model that makes it countable
This only works if it can be quantified, and increasingly it can. Natural capital accounting, full-cost and true-cost accounting, and the emerging disclosure frameworks all do the same essential job: they attach a number to the water, soil, carbon and cleanup that used to sit outside the ledger. The moment those numbers land inside the accounts, three things flip. The extractive business’s hidden liabilities become visible. The restorative business’s rebuilt capacity becomes a countable asset. And the comparison between them stops being a matter of reputation and becomes a matter of net worth.
The future fitness move
Run the experiment for real. Take your biggest dependencies — water, soil, energy, materials, supplier health, your own people — and put a defensible cost on drawing them down and a defensible value on restoring them. Don’t chase perfection; start with the largest assumptions, the ones that would move the number most.
Then ask the only question that matters: if that full cost sat inside your accounts today, are you still profitable? If the honest answer is no, you don’t have a sustainability problem. You have a solvency problem with a deadline — and that deadline is arriving faster than most boards think, because the machinery that prices the invoice is no longer slow. The restorative model is not the ethical option. It is the only version of the business that is still solvent once the invoice arrives.
The bill is coming either way. AI is what turns “eventually” into “soon.” Restorative businesses are the ones who read it early — and rebuilt before it was priced.
