Sample data

No input yet — a real flooring product, read the way your own text, URL, or PDF will be. Each claim is read twice: the impression it invites, and what its evidence establishes. The gap is the greenwash risk.

Subject: Evidence request — 7 sustainability claims

Hi,

I'm evaluating these materials for a current project and would like to substantiate the sustainability claims below before specifying. For each, could you share the supporting evidence and the specific details noted?

1. “Claims PFAS Free”
   Please share a Chemical Exclusion Statement or GreenScreen Certified, stating the chemical family, scope, threshold, test method or attestation and certificate level.
   (Ask which components were tested, the detection threshold, and whether this is a test report or just a statement.)

2. “Has Environmental Product Declaration”
   Please share an Environmental Product Declaration, stating the program operator, product category rule, declared unit, lifecycle modules and valid until.
   (An EPD reports numbers; it doesn’t mean low. Ask for the GWP and whether it’s product-specific.)

3. “Claims Recycled Content”
   Please share a Material Content Disclosure or GreenCircle Certified Certificate, stating the content type, percentage, calculation basis, product scope and source authority.
   (Ask pre- vs post-consumer, the percentage, and whether it’s the whole product or one layer.)

4. “Has CDPH Low-Emitting Material Test”
   Please share an Indoor Air Quality Emissions Certificate, stating the program or method, certificate id or report, valid until and product scope.
   (CDPH method references need the tested product scope and report/certificate basis.)

5. “Claims Low VOC Emissions”
   Please share an Indoor Air Quality Emissions Certificate, stating the program or method, certificate id or report, valid until and product scope.
   (Low-VOC emissions should not be confused with VOC content; require method and threshold context.)

6. “Has Product-Specific EPD”
   Please share an Environmental Product Declaration, stating the program operator, product category rule, declared unit, lifecycle modules and valid until.
   (It’s disclosure, not a pass/fail. Compare the GWP to a baseline before calling it low.)

7. “Has FloorScore Certification”
   Please share an Indoor Air Quality Emissions Certificate, stating the program or method, certificate id or report, valid until and product scope.
   (FloorScore is an emissions certification; do not represent it as a chemical-content or zero-VOC claim.)

Where a claim is supported only by a product-page statement rather than a test report or program record, please let me know — that affects how I can rely on it.

With thanks,
[Your name]
