Licensed GreenScreen® Profilers

GreenScreen® Profilers are organizations that have demonstrated expertise in toxicology and chemistry and that have the capacity to provide GreenScreen® assessments on a consulting basis. The licensed profilers are kept up to date on all method revisions, and Clean Production Action audits their application of the method to ensure that it is being applied as intended.
