NSF International offers chemical reviews in accordance with Clean Production Action’s (CPA) GreenScreen for Safer Chemicals program. GreenScreen reviews, which are offered through NSF International’s sustainability division, allow organizations to substitute hazardous chemicals with safer alternatives.
CPA's GreenScreen for Safer Chemicals is a comparative chemical screening method that focuses on hazard reduction and informed substitution. NSF’s team of toxicologists, chemists and biologists perform comparative chemical hazard assessments by reviewing product ingredients and formulations in accordance with the Green Screen protocol. Based on this analysis, chemicals earn one of four benchmark scores, each defining progressively safer chemicals. For example, benchmark one indicates a chemical of high concern, while benchmark four indicates a chemical with low hazard levels. Benchmark U is reserved for chemicals with insufficient data.
Offering GreenScreen chemical reviews complements NSF Sustainability’s expanding portfolio of green chemistry and sustainability services, which also includes the Environmental Protection Agency's Design for the Environment (DfE) and GreenBlue’s CleanGredients.
