Of the thousands of chemicals available for commercial use, only about 1% have ever gone through testing to assess their effects on human health and the environment. In TCO Certified, we use the GreenScreen® for Safer Chemicals to identify a pathway to safer alternatives to be used in certified products. GreenScreen offers an objective, scientific way of assessing these potential effects and identifying safer alternatives to the most hazardous substances.

Developed by the US-based non-profit Clean Production Action, GreenScreen provides a structured approach to evaluating human health and environmental safety data for a variety of chemical substances. Once a substance is assessed in accordance with these risks, the GreenScreen methodology assigns it to one of five possible Benchmark scores, based on the level of concern.

Since 2015, TCO Certified has incorporated the use of GreenScreen to identify safer flame retardants that replace restricted halogenated substances. These safer alternatives are listed on the TCO Certified Accepted Substance List. In TCO Certified generation 8, we have added plasticizers to this process since we have identified safer alternatives to the four plasticizers currently restricted in RoHs, for use in certified products. We will also be assessing industrial cleaners and solvents process chemicals in accordance to GreenScreen with the goal to identify safer alternatives that can be used during manufacture.

For compliance with TCO Certified, a chemical substance included in a certified product must achieve a GreenScreen score of Benchmark-2, -3, or -4.
