– TCO Certified Accepted Substance List

Safer alternatives to hazardous substances listed here

Hazardous substances in IT products are a risk to human health and the environment. Criteria in TCO Certified aim to reduce or eliminate the use of these substances, drive transparency and develop pathways to safer alternatives.

Simply banning substances isn’t enough. We need better information about the substances that are being used to replace them. With TCO Certified, a chemical is considered a high risk until it is proven to be otherwise. GreenScreen® for Safer Chemicals is used to identify a pathway to safer alternatives. Only plasticizers, flame retardants and process chemicals that achieve a benchmark score of 2, 3 or 4 by a Licensed GreenScreen Profiler are added to TCO Certified Accepted Substance List and may be used in the products and manufacture of certified products.
