How this ranking works

Each product's score is the percentage-weighted plastic share of its listed fiber composition — polyester weighs 100, viscose 10, cotton 0, with every weight public. Only products whose material evidence passed a completeness audit are ranked here; a low score with incomplete evidence is a conservative estimate, not proof of a plastic-free product.
