TEN CONCEPT BRIEFS · Chapter I.01 — The Ninety Days
One page each. A reader who reads only these ten pages has the chapter.
BRIEF 1 — Scarcity as a Ratio
The idea. Scarcity is not a quantity. It is a relationship between how fast you draw on something and how fast it comes back.
S = D / (R · r)
D = demand per period R = the standing stock
r = regeneration rate per periodA thing is scarce when D > R · r. Conventional economics almost always sets r = 0 — it treats the stock as fixed and reasons only about how to divide it. That is correct for a barrel of oil already pumped. It is wrong for a forest, a fishery, a soil, a skill base, a customer relationship, or a reputation.
Worked example. A woodlot holds 1,000 tonnes of standing timber and grows at 4 percent a year. Its regeneration is 40 tonnes per year. Draw 30 tonnes a year and the stock rises; the sustainable draw next year is larger than this year's. Draw 50 and the stock falls, and each year's sustainable draw is smaller than the last. The difference between those two policies is twenty tonnes and the direction of the entire enterprise.
Why it matters. It gives you a third lever. Everyone knows you can reduce demand or find more supply. Almost nobody in a commercial setting is managing r. Regenerative economics is, formally and completely, the discipline of operating on r.
You already know this because you have watched a team that was pushed too hard get slower, and a team that was invested in get faster, and you did not need a model to see which one was drawing down its stock.
BRIEF 2 — The Positive Core
The idea. Every organisation is already doing something regenerative, and almost nobody has costed it.
This is not a morale-building claim. It is an observation about how such practices enter organisations: sideways. Someone protected a supplier. Someone refused to replace a machine that still worked. Someone built a team that people do not leave. None of these arrived with a business case, because none of them seemed to need one — and so they sit in the accounts unlabelled, outperforming quietly.
Where to look. Five places, in this order: waste streams; the team with anomalously low turnover; the asset that outlived its depreciation schedule; the supplier you have never re-tendered; and the thing people are quietly proud of. The last one is found by asking, out loud, in a room.
Worked example. A manufacturer discovers that one plant's maintenance supervisor has been rebuilding a press rather than replacing it for eleven years. The replacement cost is £400,000 every eight years. His rebuild programme costs £22,000 a year. Nobody had ever put those two figures on the same page.
Why it matters. It is far easier to grow something already working than to install something that is not. Starting from the positive core means your first result is a measurement, not a forecast — and a measurement is very much harder to argue with.
BRIEF 3 — Appreciative Inquiry, and the Four Ds
The idea. Systems move in the direction of what they persistently ask about. So ask about what gives life.
Appreciative Inquiry, developed by David Cooperrider and Diana Whitney, is not positive thinking. It is a method with a defended empirical claim: an organisation that spends its inquiry on deficits gets very good at cataloguing deficits, and one that spends its inquiry on strengths gets very good at multiplying strengths.
The four Ds.
- Discovery — what is already working, at its best?
- Dream — what becomes possible if that were the norm?
- Design — what structure would make it the norm?
- Destiny — how does it sustain once nobody is pushing?
The house adds a fifth: Delight. A design that is merely correct does not get adopted; a design that is a pleasure to be inside does. Delight is not decoration — it is the adoption mechanism, and it is why a model spreads without a mandate.
The question rule. Never "what is broken?" Always "when has this worked, what made it work, and what would it take to have more of that?"
Why it matters. The deficit question and the appreciative question aimed at the same situation return different data, and the appreciative one returns data you can build on.
BRIEF 4 — Energy Return on Investment
The idea. What matters is not how much energy exists. It is how much energy it costs to get energy.
EROI = energy delivered / energy invested to deliver itThe numbers.
| Source | EROI | Net energy to society |
|---|---|---|
| Oil, 1930 | 100:1 | 99.0% |
| Oil, today | 15:1 | 93.3% |
| Solar photovoltaic | 12:1 | 91.7% |
| Hall's societal floor | 11:1 | 90.9% |
The uncomfortable reading. Sunlight arrives at roughly nine thousand times human primary energy consumption — the flux is genuinely enormous. But the margin between what our systems return and what an industrial civilisation is thought to need is not large. Charles Hall's argument is that a society needs a system-wide EROI near 11:1 to fund everything that is not energy production: medicine, schooling, art, childhood, retirement.
What this does not mean. It does not mean renewables fail. EROI estimates for photovoltaics vary widely by method, boundary and installation, and have been improving. The figure is contested and is treated properly in Volume III.
Why it matters. It is the discipline that keeps abundance honest. The abundance is real; the margin is thin; a serious economics says both sentences and refuses to choose between them.
BRIEF 5 — The Crossover Year
The idea. Regenerative options usually start behind. The question that decides everything is not whether they overtake, but when.
Model it simply. Let an extractive operation decline at d per year as its stock depletes, and a regenerative one compound at g as its stock builds, with the regenerative option starting 25 percent behind.
extractive -3%/yr vs regenerative +2%/yr -> crosses in year 6
extractive -5%/yr vs regenerative +3%/yr -> crosses in year 4The real problem this exposes. Four to six years is longer than the tenure of most people who would have to approve it. That is not a failure of the economics. It is a mismatch between the horizon of the asset and the horizon of the decision-maker, and it is the single largest structural obstacle in this book.
What follows from it. Do not propose a four-year programme. Propose a pilot sized so the crossover lands inside a budget cycle. Then use the result to buy the four-year programme.
Why it matters. Because "it pays off eventually" has never persuaded a capital allocation committee, and it never will. A date will.
BRIEF 6 — Pilot Sizing
The idea. There are exactly two constraints on a pilot, and they pull in opposite directions.
Large enough: effect > 3 x (period-to-period noise)
Small enough: cost < the discretionary authority of
one already-persuaded personThe first constraint exists because a result inside the noise band is not a result. It is an anecdote with a decimal point, and it will be argued away by the first person who does not want it to be true. Three times the standard period-to-period variation is a rough but serviceable threshold.
The second constraint exists because approval processes kill pilots. Every additional signature is an additional opportunity for the answer to be "not this quarter." A pilot that fits inside one person's existing discretion does not need a process.
When no pilot satisfies both. This happens, and it is informative. It means either your effect is too small to matter — in which case choose a different candidate — or your organisation's discretionary authority is too concentrated, which is a sponsorship problem, not a measurement problem.
Why it matters. Most transition attempts die at exactly this point, and they die because the pilot was sized to be impressive rather than to be measurable.
BRIEF 7 — The Baseline
The idea. The most valuable document in the whole ninety days is a signed piece of paper that says what was true before you changed anything.
Why it must be signed, and signed early. An unagreed baseline is not a baseline. It is a future dispute. When the result arrives, anyone who dislikes it will attack the comparison, and if the comparison was never agreed, they will win — not because they are right, but because the burden of proof lands on you.
What a baseline needs.
- The metric, defined precisely enough that two people compute it identically.
- The period, long enough to include normal variation.
- The method, written down.
- The verifier, named — internal audit is sufficient and is usually free.
- Two signatures: the sponsor and finance.
The discovery hidden inside this. Very often you will go looking for a baseline and find there isn't one. That is not a setback. It is the finding: regenerative practice is under-adopted largely because it is unmeasured, and the fix for that is a report, not a philosophy.
Why it matters. Everything downstream — the facility, the repayment, the story, the scale-up — rests on this one page.
BRIEF 8 — The Shared-Savings Facility
The idea. Finance the transition out of what it saves, so it never competes with anything for capital.
This is the structure of an energy performance contract, and your organisation may well have used one already without recognising the precedent.
The mechanics.
| Term | Setting |
|---|---|
| Facility size | Verified cost + 15% contingency, inside one signature |
| Baseline | Agreed and signed before deployment |
| Verification | Named method and verifier; IPMVP if a standard is wanted |
| Repayment | 70–80% of verified savings until repaid |
| Reversion | 100% of savings to the operating unit thereafter |
| Term | Just past the computed crossover; hard review at year three |
| Security | The savings stream, and nothing else |
The reversion clause is the clever part. It costs the balance sheet nothing and it buys you the operating unit's genuine cooperation, because they are not funding head office — they are funding a facility that hands them the whole benefit once it clears.
Why it matters. It converts an ethical argument into a financing structure, and financing structures get approved by people who would never approve an ethical argument.
BRIEF 9 — The Decision Inequality
The idea. One number decides it, and it belongs on the front page.
verified annual saving
------------------------------------------ > WACC
facility size + verification cost + adminIf the return on the facility exceeds the organisation's weighted average cost of capital, this is the cheapest capital available to the organisation and should be presented in exactly those words.
What to be careful about. Include the verification and administration cost. People leave them out, the auditor puts them back in, and the credibility lost is worth more than the margin gained. Use verified savings, not projected.
The framing this unlocks. You stop being the person with the values proposition and become the person with the arbitrage. Those two people receive very different meetings.
Why it matters. Nearly every regenerative proposal is presented as a cost with a moral justification. Presented correctly, a great many of them are returns with an incidental moral benefit — and the second framing is both more persuasive and, in these cases, more accurate.
BRIEF 10 — Irreversibility
The idea. End the ninety days with one commitment that cannot be quietly undone.
A signed contract. A covenanted allocation. A published metric. A hire.
Why quietly matters more than undone. Reversal is rarely a decision. It is a slow absence of renewal — the pilot is not cancelled, it is simply not re-funded, and nobody has to defend that. Irreversibility removes the option of drift.
What it does to the organisation. A reversible pilot is an opinion. An irreversible one is a fact the organisation must now metabolise: reporting has to accommodate it, someone owns it, and it appears in next year's plan because it is already there.
How small it can be. Very. The published metric is often the strongest of the four, and it costs nothing. Once a number is in the standing pack, removing it requires someone to explain why — and that is a conversation nobody wants to have.
Why it matters. Because the failure mode of every transition is not rejection. It is evaporation.
