Authorised Declarant Status, Embedded Emissions, Certificates and Supplier Data
One Excel workbook. Chapter 10 builds a cash-flow model and stops one step short of the year that matters: it warns that budgeting only the 2026 lump sum understates 2027 “substantially”, and leaves the word where the number should be. This file supplies the number, sizes the buffer the chapter recommends and never sizes, and finds a term the surrender formula counts twice. It is free. Nothing is gated behind a sign-up, and no email address is asked for.
Appendix F · Chapters 10, 11 and 13
“Substantially” is a factor of exactly two. Certificates cannot be bought before 1 February 2027; the 2026 obligation is surrendered by 30 September 2027; and through the same year the declarant is building holdings against 2027 imports at each quarterly checkpoint. On one calendar that is €6,750 in March, €8,100 in June, €6,075 plus €27,063 in September, €6,075 in December — €54,063 against a lump sum of €27,063. A treasurer who budgets only the lump sum has budgeted 50.1 per cent of the year. And the two is structural, not coincidental: the factor doubles while the checkpoint is a half, so half the 2027 obligation is exactly the whole of the 2026 one.
The surrender formula counts one term twice. Step four of chapter 10 says it applies the CBAM factor and the free-allocation adjustment. Its own table applies the factor and nothing else — 14,400 × 2.5 per cent = 360, with no room for a second multiplier, so the implied adjustment is exactly 1.00. The table is right: chapter 11 sets the factor and the retained free allocation as complements, so the factor already carries the adjustment. But chapter 11 also states the formula as five separate terms including that adjustment. A reader who builds from the formula arrives at a smaller obligation than the chapter’s own worked example — and under-declaring is what Article 26(1) sanctions.
The cap the chapter warns about does not bind. Hold O(1+b), surrender O, repurchase O×b, cap O. The cap binds only above a buffer of 100 per cent of the obligation. At ten, twenty or fifty it does not bind at all. What binds is the 31 October deadline — a diary entry with an owner, not a financial constraint, and it should not be priced like one.
Which makes the buffer close to free, and the decision independent of the penalty. Thirty-six certificates cost €2,700 and, carried eight months at five per cent, cost €90. The break-even probability of a shortfall does not depend on the buffer size — carry and protection scale together, so the ratio is identical at five per cent and at thirty. And expressing the penalty as a multiple of the certificate price puts the break-even between 3.3 and 0.7 per cent across the whole plausible range, so the decision never needs the indexed figure chapter 13 rightly refuses to print.
And €3.40 a tonne becomes €65 by 2030. Same book of imports, same intensity, same price — only the factor moves: €13.50 in 2028, €30.38 in 2029, €65.47 in 2030, €135.00 in 2034. Nineteen times by 2030, which is inside the horizon of every supply contract being signed now. The workbook also tests chapter 11’s claim that four fifths of the increase falls after 2029: it is 79.5 per cent, exact to a tenth of a point, and the verdict cell prints CONFIRMED. Twenty-eight checks.
Go to sheet 4 and read the last two rows. Then replace Northbeck’s four volume cells on sheet 1 with your own quarterly imports and the intensity with your own supplier figure: everything downstream is linear, so the whole calendar rescales in five keystrokes. Then go to sheet 5 and change the penalty multiple — the break-even column closes the argument about whether to hold a buffer without anyone having to establish the indexed penalty first.
It cannot confirm the regulation. The book is unusually careful about this and the workbook keeps its caution: the checkpoint percentage, the checkpoint dates and the phase-out schedule are the figures as consistently reported, and the book says plainly that a verbatim read of the consolidated text returned a different percentage in one case. Confirm them against the consolidated regulation before you rely on any of this operationally, and record the date of your read. The workbook can only tell you what follows if the parameters are what they are reported to be — which is why every one of them is an editable cell rather than a constant.
| Amber fill | an input — you may edit these |
| Grey fill | a formula — do not overtype these |
| ADDED | an input the book does not state — four treasury parameters, and nothing else |
| Checks sheet | twenty-eight controls — seven exist only to reproduce the book before extending it |
Northbeck Metals is the book’s own invented company and the volumes and intensity are its own. The prices, dates, factors and rules are the published framework as the book reports them. This is not legal or compliance advice, and the regulation should be confirmed against its consolidated text.
The workbook opens in Microsoft Excel, LibreOffice Calc, Google Sheets and Numbers. It uses no macros and no add-ins, so nothing needs to be enabled or trusted. If your spreadsheet asks to update links on opening, decline — there are none.
