What this toolkit is: a complete implementation and quantification toolkit for running one full product carbon footprint (CFP) study under ISO 14067:2018 — from commissioning and scope decisions through inventory, calculation and interpretation to the study report and whatever may be said publicly about the result. ISO 14067:2018 is a quantification standard: it sets principles, requirements and guidelines for quantifying and reporting the carbon footprint of a product. It is not a management-system standard, and there is no certification against it — a CFP is a measured quantity in kg CO2e per functional or declared unit, not a grade, a label or a pass. This toolkit is built around that fact: its job is to make the number defensible and to keep every claim made from it inside what the study actually supports.

The three-component discipline: wherever the result is stated, the fossil, biogenic and direct land-use-change components are reported separately — never silently merged into a single figure that hides where the carbon came from. Biogenic carbon is carried as an uptake-and-release pair across the life cycle; carbon stored in the product is stated as content and held out of the result, so a stored-carbon figure can never be dressed up as a removal. A partial CFP is always labelled partial, with its boundary printed next to the number. Emission factors are treated as data with provenance: source, year and geography are recorded for every factor, in the workbook and in the report.

Two complete worked studies: the toolkit teaches by finished work, not by fragments. Northgate Plastics Ltd, a fictional manufacturer, runs a complete study of a 20-litre HDPE jerry can: partial CFP 2.68 and full CFP 2.83 kg CO2e per declared unit, every stage printed row by row so the result can be re-derived independently — including the inventory balance check that catches a 460 kg booking error, and a worked uncertainty treatment that scores the significant flows and carries a band (about ±8 percent) into the report instead of letting two decimal places pretend to be certainty. Hartwell Foods Ltd’s oat drink (1 litre at retail) takes on the harder ground: biogenic carbon and land-use change in their own columns, and a contested co-product allocation worked through the standard’s order in the open — subdivision first, system expansion tested and refused on the evidence, the dry-matter split adopted and defended, and the losing bases priced in print (the economic basis would have reported a result 15.9 percent higher). The same study refuses, on the record, a drafted claim that its oats “soak up” carbon — the arithmetic does not support it, and the toolkit shows why.

The quantification workbook (Excel) is the calculation engine: one row per flow, fossil, biogenic and land-use-change factors in separate columns with provenance beside them, and 192 working formulas producing the stage subtotals and the partial and full CFP — no hand-typed totals, no hidden arithmetic. Its Guidance sheet carries the method and both studies’ calculations, so the workbook you calculate in is the workbook the examples were calculated in. Alongside it, the study report record is built item by item on clause 7 of the standard — 29 content rows covering the results, the separately stated values and all required and optional information — so a finished report is complete by construction rather than by memory.

The claims gate: most CFP damage is done after the calculation, in communication. The toolkit’s communication, claims and critical review record routes every external statement through a gate before it may run — including a thirteen-condition comparison gate drawn from the standard’s Annex B that must be evidenced, condition by condition, before any comparative or public claim, with the limitations of Annex A built into the method rather than left as fine print. A refused claim or comparison is a normal, recorded outcome: the worked example’s first comparison attempt fails eleven of the thirteen conditions and is stopped, with the reasons kept on file.

What's inside (15 documents, all at Rev. 0):

• Pack Read Me — the pack map, the honesty rules its results are stated under, and where to start
• 01 · Guide — the CFP System Guide: the method end to end, the twelve principles as working tests, the specific greenhouse gas treatments, failure patterns
• 02 · Goal and Scope — the procedure for defining goal, scope and system boundary, with its goal, scope and boundary definition record
• 03 · Inventory — the procedure for collecting and validating life-cycle inventory data, with its activity data and data quality record (ten-aspect quality assessment, balance checks, weakest datasets named)
• 04 · Quantification — the calculation procedure (allocation in the standard’s order, impact assessment, interpretation, sensitivity) with the quantification workbook
• 05 · Report and Claims — the reporting, communicating and critical review procedure, with the clause-7 study report record and the communication, claims and critical review record
• 06 · Worked Example — Worked Examples: both complete studies, Northgate and Hartwell, end to end
• 07 · Completion Notes — per-artifact notes: the fields users most often get wrong, the judgement calls, and a check to run before each artifact is closed
• 08 · Training — a 30-slide overview deck with speaker notes
• 09 · Traceability — a 155-row matrix mapping every clause, subclause, annex heading and defined term of ISO 14067:2018 to the place in the toolkit that addresses it

Who it is for: LCA and carbon footprint practitioners who want a disciplined, auditable study file rather than a spreadsheet that grew; sustainability and quality managers commissioning or reviewing a first CFP and needing to know what a defensible study looks like from the inside; and consultants who run CFP studies for clients and want the records, gates and report structure already built.

How it works: commission the study and read the guide’s opening sections → fix the goal, scope, boundary, cut-off and data requirements and approve them before any data is collected → collect and quality-assess the inventory, run the balance checks, and name the weakest datasets → allocate in the standard’s order, calculate by formula in the workbook, interpret and sensitivity-test → assemble the report on the clause-7 record, pass critical review, and communicate only what the claims gate allows — then log the tracking baseline so the next study starts from evidence, not from scratch.

Every document is an editable Word or Excel file with [Organization name] placeholders — no locked PDFs, no licence keys. Honest limits: the emission factors used in the worked examples are labelled ILLUSTRATIVE secondary values, printed so every calculation can be followed and checked — for a real study you substitute your own licensed inventory data. The toolkit quantifies and reports a footprint; it does not verify one (verification is a separate activity under ISO 14064-3, performed by others) and it certifies nothing. It supports your organization’s CFP work using ISO 14067:2018; it does not include the ISO 14067 standard itself.
