How JoinEthically Investigates Ethical Claims Like "Recycled Polyester"

JoinEthically investigates claims such as "recycled polyester" by tracing them back to the mills where the material is actually made, rather than relying on brand press kits. Its investigation into three major labels' recycled-fabric claims found that the certifications checked out but the volume math behind them did not — meaning a label can be technically accurate while the quantity of recycled content it implies is not supported. This approach applies to any claim that depends on a supply chain you can't see from the product page: recycled content, traceable wool, direct trade, and similar sourcing statements.

The core method: follow the claim to the mill

The platform's stated editorial standard is that scores and investigations are assembled from primary sources — certifications, disclosures, and factory audits — and never from brand press kits. For a claim like "recycled polyester," that means the verification doesn't stop at the certificate. It continues to the facility that produced the fabric, where the numbers behind the claim can be checked.

The fast-fashion investigation illustrates the distinction:

• The certification is real. A mill can hold a valid recycled-content certification.
• The volume math may not hold. How much certified recycled material actually flows into a given line of garments is a separate question, and it's the one the investigation found was not being checked by anyone outside the mills.

So when you see a recycled-fabric claim, the useful question isn't only "is there a certificate?" but "how much of this product is actually made from the certified material, and who verified that?"

What gets checked, and what doesn't

JoinEthically describes a single scorecard applied to every product and company, built on three questions:

Scores are assembled by editors from primary sources, and readers can see the sourcing behind every point. Scores are re-checked by hand rather than only at intake, so a score moves if a company changes course.

Why "certified" and "accurate" aren't the same thing

The gap the investigation exposes is a general one worth understanding: certification systems verify that a material can be traced, not that a specific product contains the amount a shopper would assume. A brand can therefore make a statement that is literally true while the implied scale is misleading.

For a concrete case: a label states a garment is made with recycled polyester, and a certificate exists for the mill's recycled input. The unverified step is the ratio — how much of that garment's fiber is the certified recycled material versus virgin polyester. That ratio is what determines whether the claim means what a shopper thinks it means.

How to use this when you're evaluating a claim

1. Find the primary source, not the marketing page. Look for the certification body, the mill, or the disclosure the brand cites.
2. Ask what the certification actually covers. Traceability of a material is not the same as the percentage in the finished product.
3. Check whether anyone outside the company verified the numbers. In the fast-fashion case, the answer was no until the investigation did it.
4. Treat the score as sourced, not as a vibe. JoinEthically's stated model is that every point traces back to a document you can inspect.

Where this fits in the wider platform

Investigations are one part of the site, alongside independently scored product reviews, company scorecards built from public disclosures and supply-chain audits, practical guides, vetted charities, and a community forum. The investigation format itself is editorially produced and labeled — the recycled-polyester piece is credited to an investigations editor and marked as an 11-minute read, signaling a reported piece rather than a summary.
