For the person working inside a gainshare arrangement — where a defined share of verified improvement returns to the people who created it. This chapter is about how to read a boundary honestly, and a gainshare is a boundary: a line, a measurement, and a consequence for crossing it. Everything the chapter says about grading evidence applies directly to the scheme you are paid under.
A gainshare has four parts: a baseline, a measure, a share, and a period with a verifier. Look at that list again beside the chapter's definition of a boundary: a control variable, a proposed value, an uncertainty band, and a reading.
They are the same object. A gainshare is a boundary with money attached, and everything that goes wrong with planetary boundaries goes wrong with gainshares, for the same reasons and in the same order.
So this workbook does one thing: it teaches you to grade your own scheme the way an auditor would grade a nature statement, and then to ask for the specific changes that grading reveals.
Exercise 1.1 — Grade your own measure (two hours)
Take your scheme document and apply the chapter's three tests to the measure you are paid on.
Write A, B, C or D against your measure, with one sentence of reasoning.
What each grade means for you.
Exercise 1.2 — Find where your scheme already reports by place (one week)
The chapter's appreciative cases all share one property: they report at the scale where the effect happens. HELCOM sets nutrient limits by Baltic sub-basin. Lake Taupō caps nitrogen by catchment. TNFD's first instruction is Locate.
Find the one place your scheme already does this — one line, one cell, one sub-total that is reported at the level of the actual work — and write down who put it there. That person is your ally for everything that follows, and they already believe the argument.
Exercise 1.3 — The appreciative team conversation (45 minutes)
Run this with your team. The wording matters:
"Think of a period when the scheme paid well and it clearly reflected what we actually did. What was different about how it was measured that time?"
Take notes on the measurement, not the outcome. You are assembling evidence about which measures track your work honestly, which is the highest-value thing you can bring to a scheme review.
Exercise 2.1 — The band width of your own baseline (90 minutes)
This is the chapter's central computation, applied to you.
Your baseline was set from a period of data. That data has variation. Compute the period-to-period standard deviation of your measure, and then:
band width = (upper plausible baseline − lower plausible baseline)
band share = band width ÷ the baseline value
Now compare with the chapter's table. The tightest published planetary boundary band is ozone at 5.3 percent of its boundary. The widest is the extinction rate at 900.0 percent. The Grade A boundaries average 24.1 percent, median 20.5 percent; the Grade D pair average 483.3 percent — a difference of 20.1 times on the means and 23.6 times on the medians.
If your own band share is above about 30 percent, your baseline is a judgement wearing a number, and any result inside that band will be arguable by anyone who wants it to be. That is not a complaint; it is a specific, fixable finding, and the fix is a longer baseline period or a tighter measure.
Exercise 2.2 — The aggregation test on your own scheme (45 minutes)
The chapter's division, applied to you.
190 Mt N/yr ÷ 1,600 Mha = 118.75 kg N/ha/yr
the same total on a fifth = 593.75 kg N/ha/yr 5.0 x
The point is that the global total is identical in both worlds and the outcomes are not. Now ask: is your gainshare measured on a total that would be identical if your team's contribution were zero and another team's had doubled?
If the answer is yes, you are being paid on an aggregate that is invariant to your own work. That is the single most common structural defect in gainshare design, it is exactly the defect Blomqvist and colleagues found in the footprint aggregate — where five of six components sit at or below unity and the carbon term carries 37.5 percent of the total and 100 percent of the overshoot — and the fix is the same one: report the component, not the composite.
Exercise 2.3 — Covenant or stock? (45 minutes)
Find out which shape your scheme's consequences have, because they are usually mismatched to the thing being measured.
position $500,000,000 illustrative
overshoot 5 %
---------------------------------------------------------------
under a COVENANT $500,000,000 the whole thing
under a STOCK $25,000,000 proportional
ratio 20.0 x
Schemes with a gate — miss the threshold and the pool is zero — are covenants. Schemes with a slope — the pool moves with the improvement — are stocks. A gate on a measure with a wide band is the worst combination available: a step consequence on a number nobody can defend to a decimal place. If that is your scheme, you have found the thing worth raising, and you can put a ratio on it.
Exercise 2.4 — The honest negative about your own scheme (30 minutes)
Write the strongest case against it. Really write it.
Bringing one of these forward yourself, with the arithmetic, is the fastest route to being taken seriously by the people who run the scheme.
Exercise 3.1 — Build the four statements for your team (two weeks)
Your team has all four kinds and reports one.
| Statement | What goes in it, on your floor |
|---|---|
| Covenant schedule | The one or two hard gates: a safety limit, a consent condition, a permit threshold. Level, reading, headroom. |
| Asset register | Condition of the things you tend — the machine, the tooling, the skill base, the relationships. Gross, impairment, net. |
| Flow account | Throughput where it lands: waste by stream, energy by line, nutrient or emission by receiving place. |
| Watch list | Real, material, not reliably measurable. Disclosed, graded, never added to anything. |
Take the asset register first. It is where the uncounted value sits, because a stock that is being tended appreciates and nothing in a standard scheme records that.
Exercise 3.2 — Build the baseline nobody built (two weeks)
Choose the one thing in your register that you can see improving and nobody counts.
Then change nothing for the full period. Measuring before intervening feels like lost time and it is the foundation of every claim you make afterwards.
That sixth line is what this chapter adds to the standard practice, and it is worth more than it looks: a proposal that grades its own measure and prints its own uncertainty band is very difficult to attack, because the attack has already been made by the person proposing.
Exercise 3.3 — Ask for the local denominator (one conversation)
The single highest-value change you can request, and it usually costs nothing: report my measure against the place it happens, not against a group total.
The argument is already made for you in the chapter and in the standards. HELCOM allocates by sub-basin. Lake Taupō caps by catchment. TNFD locates before it evaluates. You are not asking for special treatment; you are asking for the denominator that every serious framework has converged on.
Exercise 3.4 — Ask what the ratchet is actually worth (30 minutes)
If your scheme has a small percentage adjustment attached to a large outcome, price it the way the chapter prices a sustainability-linked loan.
drawn facility $400,000,000 illustrative
margin ratchet 25 bp
annual value $1,000,000 / yr
consequence it claims to price $400,000,000
ratio 400 x = 0.25 %
A quarter of a percent of the consequence changes nobody's behaviour, and a scheme that costs money and buys no behaviour is a scheme with a short life. If your share percentage is at that order of magnitude relative to the value being created, say so — calmly, with the division written out. It is an argument for the scheme's survival, not against it.
Exercise 4.1 — Into the standing review (one conversation)
Get your metric, with its grade, onto whatever is reviewed monthly. Anything reviewed monthly persists; anything reviewed by exception disappears. It is usually a five-minute ask that nobody makes.
Exercise 4.2 — The second reader (this month)
One other person who understands the measure well enough to defend it when you are away, and who gets public credit for the first result. One person is a hobby; two is a practice.
Ask them to falsify your grading rather than approve it, by a route that does not use your reasoning. The author is the one person who cannot see it — which is why this edition itself is written under a rule that nobody checks their own claims.
Exercise 4.3 — The dated log (ongoing, ten minutes a week)
What changed, when, what the number did, what grade it carried. Ten minutes.
When the scheme is reviewed — and it will be — the person with a dated contemporaneous record is believed and everybody else is negotiating from memory. Highest return on effort in this entire workbook.
Exercise 4.4 — Delight, honestly (ongoing)
The chapter's delight is the relief of a document that says what it does not know. In a gainshare that has a precise meaning: a scheme people trust is one where they can see which parts are measured and which are judged.
Ask your team directly: can you point to the line where what we did shows up, and can you tell which lines are read and which are estimated? If they cannot, the scheme is not delivering its main benefit whatever it is paying — because the legibility is the benefit, and the payment is the receipt for it.
Work through this once. Keep the answers.
| Answer | Where it is written | |
|---|---|---|
| The measure, as a formula | ||
| Its evidence grade, by the three tests | ||
| Its band share — band width over baseline value | ||
| Read by an instrument, or modelled? | ||
| Reported against a place, or a group total? | ||
| Baseline value and date | ||
| Does the baseline ratchet? On what published schedule? | ||
| Gate or slope — step consequence or proportional? | ||
| Share percentage, and of gross or net | ||
| Allocation basis | ||
| Measurement period and verifier | ||
| Cap, floor, carry-forward | ||
| What is on the watch list, and is it summed into anything? | ||
| Dispute process |
Any blank row is a question worth asking, and asking it in this form — calmly, in writing, as a request for clarity rather than a challenge — is how a scheme gets better without anyone losing face.
The order matters, and it is the same order the executive in the parallel workbook is being taught: number, then story, then philosophy — and the philosophy is optional.
"I've graded the measure we're paid on against three tests — whether one number describes the whole system, whether it's read or modelled, and whether the threshold is demonstrated. It comes out as a flow reported on a group total, and the band on our baseline is wider than I'd want to defend in a review. I've built a four-week baseline on the local denominator instead, signed, and it's attached. It's one page — can I leave it with you?"
Note what that does not contain: no grievance, no comparison with another employer, no argument about fairness in the abstract. You are arriving with a grade, a band and a baseline, which is precisely what the executive is being taught to arrive with.
That is not a coincidence. It is the point of the whole volume — the practitioner and the corporation are not operating different economics, only different vocabularies.
