How to Read a Carpet Tile EPD
TL;DR
Start with the product name and backing covered by the EPD. Next check the programme operator, product category rules (PCR), declared unit and life-cycle modules. Read the environmental indicators only after those fields match the carpet tile in your specification. For comparisons, use declarations with compatible rules, units and scope; save the exact EPD revision with the tender record.
Find the product named in the EPD
An environmental product declaration (EPD) reports life-cycle environmental information for a defined product or product group. ISO 14025:2026 sets requirements for EPD programmes and declarations. For carpet tiles, the practical first question is whether the declared product, backing and manufacturing scope include the tile you plan to buy.
Read the EPD fields in order
- Product identity: manufacturer, product name, variants and manufacturing sites.
- Programme and registration: the programme operator, registration number, publication date and validity period.
- PCR and standards: the Product Category Rules and LCA standards used to calculate the declaration.
- Declared unit: for example an area or mass basis. Do not compare values calculated on different units.
- System boundary and modules: identify which life-cycle stages are included and which are not declared.
- Impact indicators: record the indicator name, unit, reference service life if supplied, and any scenario assumptions.
- Verification: identify the independent verifier and whether the declaration is programme-verified.
- Comparability note: compare only declarations with equivalent products, PCR, units, boundaries and assumptions.
Compare like-for-like declarations
Imagine two carpet tile EPDs with different declared units or life-cycle modules. Their headline impact numbers cannot be compared directly. Put the PCR, unit, modules, service-life assumptions and indicator units side by side first. If they differ, ask the programme operator or supplier for a comparable basis rather than ranking the products from a single number.
Add the EPD to a project submittal
For a project file, keep the EPD registration number, issue and expiry dates, version, covered product code or range, PCR, declared unit, modules and verification details beside the finish schedule. A separate product data sheet or test report is needed for technical properties such as fire classification or acoustics.

Frequently asked questions
What does a carpet tile EPD describe?
It reports life-cycle environmental information for the product and scope named in the declaration.
Can two carpet tile EPDs be compared?
Compare their PCR, declared unit, modules, indicators, assumptions and product scope first.
Does an EPD give fire or acoustic ratings?
Those properties need the relevant product data sheet or test report.
