It involves a detailed review of the scientific literature to attempt to determine hazard levels for all endpoints and calculate a GreenScreen benchmark.
CoHC - Chemicals of High Concern (polymer residuals & catalysts): Version 1.4 of the GreenScreen added special rules for benchmarking polymers which include analysis of residual monomers and/or catalysts present at or above 100 ppm.
[4] For example Apple is using GreenScreen framework and similar approaches to find safer materials in its products and processes.
[5] The GreenScreen is also referenced publicly by sustainability standards in several of these industries, including the Health Product Declaration Standard (HPD),[6] Portico,[7] Building product disclosure and optimization - material ingredients credits in the US Green Building Council's LEED program,[8] the International Living Future Institute's Living Product Challenge[9] (related to the Living Building Challenge, and by various governmental bodies.
[citation needed] The GreenScreen standard is developed, maintained and published by Clean Production Action (CPA), a non profit organization, based in the United States.
[citation needed] The GreenScreen has substantial overlaps with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) and the criteria of the US EPA’s Design for the Environment.
GreenScreen includes endocrine activity, addresses PBTs more comprehensively and considers environmental transformation products.
