In today's market, green, safer chemistry is a significant competitive advantage. GreenScreen® from Clean Production Action (CPA) is the first open source screening tool to promote the design, manufacture and use of safer chemicals in products. NSF Sustainability is an approved third-party profiler of ingredients and products in accordance with the GreenScreen chemical hazard assessment protocol.

The GreenScreen method provides guidance on assessing a chemical and assigning a hazard rating (low, moderate or high) for each of 18 different hazard endpoints. The assessment results are used to assign a benchmark score to the chemical, from 1 to 4. The lowest rating of 1 indicates a chemical of high concern or one with an incomplete dataset, ratings of 2 and 3 indicate progressively safer chemicals, and the highest rating of 4 indicates a chemical with a complete dataset and low hazard levels. GreenScreen has been a major success in aiding companies and governments in substituting hazardous chemicals with safer alternatives.

Benefits of Reviews

For formulators/fabricators: The GreenScreen® assessment helps identify safer chemicals for a similar functional use and also supports informed substitution of materials and continual improvement. The benchmarking scoring system provides a simple method for non-technical buyers to consider hazards when making purchasing decisions, which reduces business risk and advances sustainability in product design.

TCO Certification, a sustainability certification for IT products, recommends the use of GreenScreen® for Safer Chemicals on halogenated flame retardants and the toxic chemicals used to replace them. 

For chemical suppliers: The GreenScreen benchmarking process provides an elegant way to communicate the safety of your product to your downstream users. Your customers can be assured that the GreenScreen report is accurate and verified.
