How these scores are produced
Product scores on this page are produced automatically. We read the composition and certification details a retailer discloses on the product page, match each material to our research database, and apply the published clothing-score process: every product starts at 100; five material factors — microplastics, PFAS, material half-life, production energy, and fiber shedding — apply penalties weighted by how much of the garment that material makes up; a sixth factor, azo dyes, applies to the garment as a whole; and a small adjustment reflects whether any certification was disclosed. GOTS, bluesign, OEKO-TEX Standard 100, and Cradle to Cradle can also mark a product azo-dye-free. We do not lab-test garments. The Analyzed Product Profile then summarizes those product scores. It is not a corporate sustainability score, and it is not the retired LLM brand assessment.

If a figure on this page is wrong, send a correction. We aim to respond within 24 hours. A review can temporarily hide a disputed claim; it is not an automatic permanent removal.
Sourced corporate evidence
These are sourced claims, not a corporate score. Missing topics are not assessed, not scored as zero.
