Where this number comes from. GreenSpecs scores the evidence a product puts in front of you: the wording of the claim, what the packaging discloses, and whether an independent certifier stands behind any of it. Each score is a GreenSpecs assessment generated by our scoring model from the product label and public claim text on the date shown. It is not a laboratory test, not a lifecycle assessment, and not a safety rating. The full method is published here.
