TL;DR

Review a carpet tile sustainability claim only after fixing the exact product identity and the claim's scope. Recycled-content statements, EPDs, VOC certificates, test reports and supplier declarations do different jobs. Check the covered product, version, method or programme, geography, issuing body and validity. A percentage, logo or broad label cannot by itself prove that the offered construction meets a project's tender requirement.

The direct answer: make every claim product-scoped

Ask for a traceable document set, not a stronger adjective. Put the claim beside the exact product code and record what the file says, where it applies, when it was issued and what the tender still needs confirmed.

Lock the product identity before reviewing an environmental claim.
Separate an EPD, a recycled-content statement, a VOC document and a supplier declaration.
Read programme, method, geography, validity and scope rather than relying on a logo.
Leave project requirements open until current evidence matches them.

Tender language often compresses different environmental subjects into one word: sustainable. A disciplined review expands the word into a document request. This page explains a review method; it does not assert any UNIJOY EPD, recycled-content level, VOC result, certificate or project outcome.

Create a tender evidence request

Record	What to check	What it cannot prove
Product identity	Series, exact code, colourway, format and backing configuration to which the claim must attach.	That a collection-wide or generic statement applies to the offered build.
Claim type	Whether the document concerns recycled content, lifecycle declaration, emissions, another test or a supplier statement.	That one document answers every environmental question.
Scope and method	Named programme/method, declared unit or boundary where applicable, covered products and exclusions.	A performance, health, fire, acoustic or suitability conclusion.
Geography and time	Market/region, issue date, version, validity and any renewal condition.	That an expired or another-region file remains current.
Tender decision	Requirement, evidence received, owner for clarification and unresolved exception.	That an unverified label meets a project criterion.

Editorial evidence flow only; it does not establish a UNIJOY product specification, test result, certificate scope, approval or project outcome.

What a green label cannot establish

Marketing wording	Evidence to request	Do not infer
‘Contains recycled content’	Current product-scoped statement explaining material, amount/basis and covered construction.	Recyclability, an EPD, emissions result or project suitability.
‘EPD available’	The actual declaration, programme, version, product scope and validity.	A universal environmental preference, health claim or tender compliance.
‘Low VOC’	Current certificate or test document with method, sample and scope.	Any other performance result or coverage for another product.
Leaf logo / ‘eco’	The criteria, scheme owner, scope and current supporting file.	That every environmental or project requirement is met.
‘Sustainable backing’	Exact backing configuration and relevant current evidence for the stated claim.	Recycled percentage, acoustics, stability, recyclability or suitability.

Review published technical-resource categories first, then send the exact product reference and tender wording when you need a current document or clarification about its scope.

Frequently asked questions

Does an EPD prove that a carpet tile is suitable for a tender?

No. An EPD is a defined environmental declaration with a stated product scope and programme context. Compare that scope with the tender requirement and request any other evidence separately.

Can a recycled-content percentage prove a whole sustainability claim?

No. It needs a product-scoped basis and does not by itself establish recyclability, emissions, EPD status, certification scope or suitability for a project.

What should be checked on a carpet tile environmental document?

Check the exact product identity, document type, issuer/programme, version or issue date, method, geography, validity, covered construction and exclusions before using it in a tender record.
