Red List Free Materials
Materials verified clear of all 800+ chemicals on the Living Building Challenge Red List — third-party documented.
Toxicity Screening — All Clear
This material screens clear across all seven independent toxicology authorities we use on every project.
Material Type
Living Building Challenge Material Certification
Material Description
Red List Free is the most stringent material-level certification in residential construction. To earn the LBC Red List Free label a product must contain zero ingredients from the Living Building Challenge's list of ~800 chemicals (organized into 22 classes including the families on our Avoid list). The certification is third-party verified by the International Living Future Institute, with the manufacturer required to disclose every intentional ingredient down to 100 ppm. Declare and HPD (Health Product Declaration) labels are the documentation standards. EBH specifies Red List Free wherever an equivalent product carries the certification — paints, flooring, cabinetry, insulation, and increasingly even electrical and plumbing components.
Composition & Origin
Health Profile — All Endpoints Clear
Severity scored 0–10 against the same 10 hazard endpoints we use for the chemical families on the avoid list. Every score is 1–2 — essentially no signal across every endpoint.
Common Forms & Brands
- Declare label (International Living Future Institute)
- HPD — Health Product Declaration
