The Ninety Days

Volume I — Transition: From Here to the Living Economy

THE PLATE

A woman in a gold silk blouse writing in an open book at her desk, morning light through the window behind her catching the candles. — Plate I.01The Ledger at First Light.A ninety-day plan is not a document. It is a decision that has been given a shape, and then given a morning.

THE LETTER

You did not come to this book for a philosophy of economics. You came because something in the way your organisation makes money has started to feel like it is working against the thing your organisation is for, and you would like that to stop being true.

That is the right instinct and it is a more common one than you think. The Chief Financial Officer of a mid-sized manufacturer, a farmer with three hundred hectares and a bank covenant, a fund manager with a mandate that mentions impact in the third paragraph, a founder of eleven people, a city treasurer — all of them arrive at the same sentence: I can see what the better version looks like, and I cannot see how to get there from inside next quarter's numbers.

This chapter is about the ninety days. Not the vision, not the paradigm, not the theory of value — those are Volume II, and they are worth your time later. This is the practical question, answered practically: what does a person actually do, starting on a Monday, to move a real organisation toward a regenerative economics without asking anyone for permission they will not get?

The answer is unglamorous, which is why it works. You are not going to transform anything in ninety days. You are going to do four things: find the place where the living-systems approach is already outperforming inside your own numbers, measure it properly, make one small irreversible commitment, and tell one true story about it to the person who controls the next allocation.

That is it. That is the whole chapter. Everything below is how.

The reason it is ninety days and not a year is that ninety days is one reporting period, and one reporting period is the smallest unit of organisational time that produces evidence a finance function will accept. You are not trying to win an argument. You are trying to produce a number.

— The Editors

DISCOVERY

What is already working

Begin here, and begin here always: something in your organisation is already regenerative and nobody has costed it.

This is not encouragement. It is an empirical regularity, and it holds because regenerative practices tend to enter organisations sideways — as a maintenance decision, a retention initiative, a supplier relationship somebody protected, a piece of equipment somebody refused to replace. They arrive without a business case because nobody thought one was needed, and so they sit in the accounts unlabelled, quietly outperforming.

The first ninety days are an act of discovery in the technical sense: you are looking for the positive core that already exists, because it is far easier to grow something that is working than to install something that is not.

Consider what has already been found by people who went looking.

Interface, the carpet manufacturer. In 1994 Ray Anderson set his company the goal of taking nothing from the earth that could not be replaced. What is less often reported is where the money came from: the first several years of the programme were funded almost entirely by avoided waste. Interface's own reporting through the 1990s and 2000s attributes several hundred million dollars of cumulative avoided cost to the waste-elimination programme alone — money that was, before the programme, leaving the building unnoticed as offcuts and rejected runs. Anderson did not begin with a new plant. He began by finding what the plant was already throwing away.

Mondragon, in the Basque country. Founded 1956, now a federation of roughly ninety-five cooperatives employing on the order of seventy thousand people. The number worth carrying is not its size but its behaviour under stress: through the Spanish financial crisis, when national unemployment rose above 26 percent, Mondragon's cooperatives relocated workers between businesses and reduced hours and pay rather than shedding people. Some parts of the federation failed — Fagor Electrodomésticos, a founding cooperative, went into insolvency in 2013, and that failure is part of the record and part of the lesson. The federation absorbed most of the displaced workers. The structure did not prevent business failure. It changed what business failure did to people.

Preston, in Lancashire. Beginning around 2013, the city council and a group of anchor institutions — the university, the police, the housing associations, the college — examined where their combined procurement spend went and deliberately redirected what they could to suppliers within the local economy. Independent evaluation of the programme found that the proportion of anchor institution spend retained in Preston rose substantially over the following years, from a low base to a considerable multiple of it. The mechanism was not new money. It was the same money, routed differently.

Grameen Bank. Muhammad Yunus's original observation in Jobra was that forty-two people were trapped by a total of twenty-seven dollars of debt. The lesson was not that micro-credit is a panacea — the subsequent literature is genuinely mixed, and we will do that arithmetic honestly in Volume III — but that the binding constraint was not the absence of capital. It was the shape of the available capital.

Four cases, four continents, one pattern: in each, someone found a resource that was already present and already being wasted, and changed its routing rather than its quantity. That is the discovery move, and it is the whole of your first thirty days.

So: where is it in your organisation? It is usually in one of five places.

Waste streams. What leaves the building that someone would pay for?
Retention. Which team has anomalously low turnover, and what is that team doing that the others are not?
Maintenance. Which asset has outlived its depreciation schedule, and who made that happen?
Supplier relationships. Which supplier have you never re-tendered, and why has that been the right call?
The thing you are quietly proud of. Ask the question directly. People know.

Do not evaluate yet. Just find them. You are looking for four or five, and you will need only one.

THE ARITHMETIC

What works, what does not, and where the line sits

Now we cost it. This is the movement that makes the difference between a conviction and a proposal, and it is where most transitions die — not because the numbers are bad, but because nobody ran them.

First, the frame. Scarcity is a ratio, not a quantity.

Define scarcity properly and it becomes a variable you can move:

        S  =  D / (R · r)

  D  demand per period
  R  the standing stock
  r  the regeneration rate per period

A resource is scarce when demand exceeds what the stock regenerates in the period. This is elementary and it is not what most economics does — most economics treats scarcity as a property of the stock alone, which is to say it sets r = 0 and then reasons about allocation.

The consequence is the single most useful idea in this volume: there are three ways to reduce scarcity, and conventional practice only ever uses one. You can reduce D. You can increase R — find more, buy more, extract more. Or you can increase r, the regeneration rate. Regenerative economics is, formally, the discipline of operating on r.

Note what this does to the intuition. If r is greater than zero and you hold D below R · r, the stock does not deplete — it grows, and the sustainable draw grows with it. The forest, the fishery, the soil, the customer relationship, the reputation, the skilled workforce. Each is a stock with a regeneration rate, and each is routinely managed as though it had none.

Second, the energy case, done honestly.

The first edition of this work stated that solar energy arrives at roughly ten thousand times human consumption. Let us tighten it, because the precise figure is more useful.

  incident solar at the surface        173,000 TW
  global human primary energy (2023)      ~19 TW
  ------------------------------------------------
  ratio                                    9,105x

Nine thousand times. Not ten thousand — and the correction matters not because the smaller number is less impressive but because a reader who checks one number and finds it loose will not check the second one. Precision is a courtesy to the sceptic, and the sceptic is the reader you are writing for.

Third — and this is the movement that does the real work — what does not work.

An abundant flux is not an abundant supply. The relevant constraint is not how much energy arrives; it is how much energy it takes to get the energy. The measure is Energy Return on Investment, and the numbers are sobering:

  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%

Charles Hall's argument — and it is contested, which we will treat properly in Volume III — is that an industrial society needs a system-wide EROI somewhere around 11:1 to fund everything that is not energy production: healthcare, education, the arts, childhood, retirement. Below that, the energy system consumes the surplus that civilisation is made of.

Read the table again and notice the discomfort. The abundance is real. The margin is not large. An honest regenerative economics says both sentences and does not choose between them.

Here is the second honest negative, and it is the one that will decide your ninety days. Regenerative approaches usually start behind. They cost more up front, they yield less in year one, and they are financed against a hurdle rate set by the alternative. The question is not whether they win eventually. It is when, and whether your organisation can hold on that long.

So compute the crossover. Let an extractive operation decline at rate d per year as the stock depletes, and a regenerative operation compound at rate g as the stock builds. Start the regenerative option 25 percent below the extractive one — a realistic transition penalty.

  extractive -3%/yr  vs  regenerative +2%/yr   ->  crosses in year 6
  extractive -5%/yr  vs  regenerative +3%/yr   ->  crosses in year 4

Four to six years to cross, from a quarter behind. That is a real answer, and it is an uncomfortable one, because four years is longer than the tenure of most of the people who would have to approve it.

This is why the ninety-day method does not propose a four-year programme. It proposes a pilot small enough that the crossover happens inside a budget cycle, and large enough that the number is not noise. Which brings us to the size question, and to the only formula in this chapter you should memorise:

  Pilot must be large enough that:   effect  >  3 x (period-to-period noise)
  Pilot must be small enough that:   cost    <  the discretionary authority
                                               of one person who is already
                                               persuaded

If no pilot satisfies both, you do not have a pilot problem. You have a sponsorship problem, and that is Chapter I.09.

DREAM

What becomes ordinary

Imagine the version of this that has already happened, and describe it plainly, because a dream stated in the future tense is a wish and a dream stated in the present tense is a specification.

In the organisation that has made this transition, the finance function is not the obstacle to regeneration. It is the instrument of it. The controller maintains a second column beside the depreciation schedule showing which assets are appreciating — the soil, the skill base, the supplier relationships, the brand's permission to be trusted — and that column is reviewed with the same seriousness as the first. Nobody finds this unusual. It is simply how the accounts are kept.

The capital allocation committee has a standing question in its papers: what is the regeneration rate of the stock this investment draws on, and does this investment raise it or lower it? Proposals that lower it are not forbidden. They are simply priced correctly, which turns out to be enough.

Procurement knows where its money lands. Not in the aggregate, sentimentally, but by postcode and by counterparty, because somebody built the report once and now it runs monthly. When a contract comes up for renewal there is a column showing what proportion of that spend returns to the local economy within one cycle, and it is one of the four numbers that decides.

The people who work there can describe how the value they create reaches them. Not as a slogan — as a mechanism, with a formula, on a page they could show you. When the business does well they can point to the specific line where that shows up in their own circumstances, and when it does badly they can point to the same line. They trust the mechanism because it is legible, and it is legible because somebody insisted on making it so.

And the organisation still meets its obligations. It pays its debts, it clears its covenants, it returns capital. This is not a story about an organisation that stopped being a business. It is a story about one that stopped leaving money on the table in the form of stocks it was silently depleting, and started counting the things it had always known mattered.

None of this requires a change in the law, a change in the tax code, or a change in anybody's heart. It requires four or five reports that do not currently exist, and one person willing to build them.

DESIGN

The ninety days, built

Here is the structure. It is deliberately narrow.

Days 1–30: Find and cost the positive core.

Run the discovery. Take the five candidates and cost each one properly — including, and this is the part people skip, the counterfactual. What would have happened without it? A retention effect is worth the fully loaded cost of the turnover it prevented, which is typically far larger than the salary line suggests once you include recruitment, ramp time, and the productivity of the team around the vacancy.

Choose one. The criteria, in order:

It is already working, so you are not forecasting, you are measuring.
Its effect is at least three times period-to-period noise.
Its cost sits inside one persuaded person's discretion.
You can describe it in one sentence to someone who does not care.

Days 31–60: Measure it properly and build the instrument.

Two workstreams, run together.

The measurement. Establish the baseline before you change anything else. You need a number from before. If you do not have one, you have just discovered the most valuable thing in the ninety days: the reason regenerative practice is under-adopted is very often that it is unmeasured, and the fix is a report, not a philosophy.

The instrument. Decide how it will be financed and how the return will be shared. This is the finance-level move and it is treated in full in the next movement.

Days 61–90: Commit irreversibly, and tell one true story.

One small commitment that cannot be quietly reversed — a signed contract, a covenanted allocation, a published metric, a hire. Irreversibility is the point. A reversible pilot is an opinion; an irreversible one is a fact that the organisation must now metabolise.

Then the story. One page. Baseline, intervention, result, and what it implies at ten times the size. Given to exactly one person: whoever controls the next allocation. Not the board, not the all-hands, not the newsletter. One person, one page, one number.

DESTINY

How it holds when you stop pushing

The failure mode of every transition programme is that it is load-bearing on one person's enthusiasm, and enthusiasm has a half-life.

Three things make it self-sustaining, and only three.

It is in the reporting pack. Anything reviewed monthly persists; anything reviewed by exception does not. Getting your metric onto the standing pack is worth more than any presentation you will ever give.

Somebody's compensation moves with it. Not necessarily much. The signal matters more than the magnitude — an unpaid metric is a hobby.

It has a second owner. One person is a hobby, two is a practice. Recruit the second owner before you need them, and recruit them by giving them the credit for the first result.

Now the honest part. Here is where this fails. It fails when the pilot is sized to be impressive rather than to be measurable, and the result comes back inside the noise band. It fails when the sponsor moves roles in month four and the successor inherits a commitment without the conviction. It fails when the measurement was built after the intervention, so there is no clean baseline and the result can be argued away by anyone who wants to. And it fails — most often — when the person running it tries to win the argument philosophically before they have won it numerically. The order matters. Number first, then story, then philosophy, and the philosophy is optional.

DELIGHT

What it feels like

There is a particular pleasure in the moment the report comes back and the number is real. It is quieter than you expect. Not triumph — recognition. The feeling of having suspected something for a long time and finally being able to put it on a page in a form that another person cannot argue with.

And then a second pleasure, better than the first: the meeting where somebody who was not persuaded uses your number in their own argument, for their own purposes, without attributing it. That is the moment a finding becomes infrastructure. It has stopped being yours, which is exactly what you wanted.

The work itself is good work. It is detective work — going through the accounts looking for the place where something is quietly going right — and detective work is one of the few kinds of labour that is intrinsically absorbing. You will find, if you are honest, that you enjoy the thirty days of looking more than the sixty days of building. That is not a flaw in you. It is a signal about what this economics is actually like from the inside: it is not sacrifice, it is noticing.

OPERATIONALIZE THIS

At the level of finance

Everything above becomes real at the moment it acquires an instrument. Here is the instrument, in the form a treasurer will recognise.

The structure: a ring-fenced regeneration facility with a shared-savings return.

You are not asking for a grant and you are not asking for philanthropy. You are proposing a self-liquidating facility repaid out of verified savings — the same structure as an energy performance contract, which your organisation may already have used without noticing the precedent.

The mechanics.

Facility size. The verified cost of the intervention, plus 15 percent contingency. Keep it inside one signature.
Baseline. Agreed and signed before deployment by both the sponsor and the finance function. This is the single most important document in the transaction. An unagreed baseline is not a baseline; it is a future dispute.
Measurement and verification. Named method, named period, named independent verifier — internal audit is sufficient and is usually free. Reference IPMVP if your organisation wants a standard to point at.
Repayment. A fixed percentage of verified savings — 70 to 80 percent — until the facility is repaid, then the savings revert entirely to the operating unit. That final reversion is what buys you the operating unit's genuine cooperation, and it costs the balance sheet nothing.
Term. Set it just past your computed crossover. If the arithmetic said four to six years, write five, with a hard review at three.
Security. The savings stream. If the intervention does not save, there is nothing to repay, and the facility should say so explicitly.

The balance sheet treatment. Where the intervention creates or improves a long-lived asset — soil, plant, a repairable product line — capitalise it and depreciate over the asset's regenerated life, not its extracted life. That is frequently the entire argument: an asset whose productive capacity is rising should not be depreciating on a schedule that assumes it is falling. Talk to your auditors early. This is a conversation about useful economic life, which is a conversation they have every year.

The counterparty. Internal first, always — treasury lending to a business unit. The internal version can be documented in a week and gives you a track record. Only once you have two completed internal facilities should you take the structure to an external lender, because now you are presenting a proven mechanism rather than a proposal.

The number that decides it. One figure, and it should be on the front page:

              verified annual saving
   ------------------------------------------  >  your organisation's WACC
    facility size + verification cost + admin

If that inequality holds, this is not an ethical proposal. It is the cheapest capital available to your organisation, and it should be presented as such.

The first ninety days on a page.

Day	Action	Artifact
1–15	Find five candidates	A list, costed roughly
16–30	Choose one, cost it properly with the counterfactual	A one-page cost case
31–45	Agree and sign the baseline	The signed baseline
46–60	Draft the facility terms; secure the one signature	Facility memo
61–75	Deploy. Begin measurement	Measurement log
76–90	First verified result; write the one page	The one page, one person

APPRECIATIVE QUESTIONS

Twelve, for a room

Discovery — what is already working

Think of a time in the last two years when this organisation did something that was clearly right for the long term and paid off sooner than anyone expected. What was it, and who made it happen?
Where in our accounts is something quietly appreciating that we depreciate?
Which of our supplier relationships would we protect even if a cheaper offer arrived tomorrow — and what do we actually get from it that the price does not show?

Dream — what becomes possible

If our finance function became the strongest advocate for regeneration in the building, what would it be doing on a Tuesday morning that it does not do now?
Imagine our reporting pack three years from now, and it contains one number we would be proud to have on the front page. What is that number?
If every person here could describe exactly how the value they create reaches them, what would change about how we work?

Design — what we build

What is the smallest thing we could commit to this quarter that we could not quietly reverse?
Who is the one person whose signature would make this real, and what do they need to see?
What baseline do we wish we had started measuring three years ago — and what stops us starting it this month?

Destiny — how it holds

What would have to be true for this to still be running when everyone currently in this room has moved on?
Who is the second owner, and what would we have to give them for it to be genuinely theirs?
What is the first sign we would see if this were quietly dying, and who would notice it first?
