Product carbon footprint or EPD: two different deliverables
A customer asks for "the carbon footprint of the product". Sometimes they want a verified CFP under ISO 14067:2018. Sometimes they want a published EPD under ISO 14025:2006, with a programme operator and a product category rule. The two overlap in method and diverge in almost everything else.
What each deliverable is.
Product carbon footprint (CFP)
ISO 14067:2018- A single impact category: climate change, expressed as CO2e per declared unit.
- Built on the LCA framework of ISO 14040 and ISO 14044.
- Cradle-to-grave by default; a partial CFP covers defined stages, such as cradle-to-gate.
- Where a CFP-PCR exists for the product category, it applies.
- Verified against ISO 14064-3:2019 and reported in a CFP study report.
Environmental product declaration (EPD)
ISO 14025:2006 · EN 15804+A2 for construction- A Type III declaration: multiple indicators, not climate alone.
- Requires a programme operator and a product category rule (PCR).
- Independently verified, then published in the programme register with a validity period.
- Comparability between EPDs is only valid inside the same PCR and programme.
- For construction products, EN 15804+A2 is the core PCR; ISO 21930:2017 applies for building works.
Which one does the requirement point to?
| The requirement says | Likely deliverable | What you also need |
|---|---|---|
| "Provide the product carbon footprint" | Verified CFP to ISO 14067:2018 | A declared unit, a defined boundary, and a decision on cradle-to-gate versus cradle-to-grave |
| "An EPD is required for tender submission" | Published EPD to ISO 14025:2006 | A programme operator, the applicable PCR, an LCA, and time for verification and publication |
| "EN 15804 compliant declaration" | Construction EPD under EN 15804+A2 | Modules A1–A3 as a minimum, and the modules the client actually requires |
| "Scope 3 category 1 data from suppliers" | Cradle-to-gate partial CFP per purchased product | Alignment with the customer's allocation and boundary rules, or the data will not be usable |
| "CBAM embedded emissions" | Neither — this is a regulatory calculation | Embedded emissions per Implementing Regulation (EU) 2025/2547, verified by a CBAM-accredited verifier |
The order that avoids rework.
Name the user and the requirement
Which customer, which tender, which framework, and the exact wording of the clause. Everything below follows from it.
Before anythingFix the declared unit
One tonne, one square metre, one unit of packaged product — with the function it delivers. A change here invalidates everything downstream.
DefinitionFix the boundary and the modules
Cradle-to-gate or cradle-to-grave; for construction, which of the EN 15804 modules. State the cut-off criteria and the allocation rules.
BoundaryBuild the inventory and the model
Primary data for the foreground system; documented secondary data with database, version and geography for the background.
LCAIndependent verification
Performed by a body that took no part in preparing the study. For an EPD, verification also has to satisfy the programme operator's own rules.
VerificationPublication or issue
A CFP results in a verified study and statement. An EPD is registered and published with a validity period, after which it must be revised or withdrawn.
