UN body that publishes the authoritative scientific assessment of climate change. In practice, the term appears in two very different places: on regulated certification documents, where it has a fixed technical meaning, and in marketing copy, where it is often used loosely to imply a benefit that has never been audited.
Treat IPCC as a starting question rather than an answer. Ask who defined it, who checks it, and whether the check covers the whole product or a single component. A claim backed by a named standard, a certificate number and an expiry date is worth far more than the same word printed on a box.
On RevWix, every product page separates verified claims from unverified ones, so when you see IPCC attached to a listing you can trace it back to the certification, the material or the company policy that supports it.
