  • All substances on this list have been reviewed and the benchmark set by approved Clean Production Action (CPA) licenced profilers.
  • All substances of a mixture shall be accounted for. Non-accepted components shall not exceed concentration levels of 0.1% by weight of the flame retardant or plasticiser.

GreenScreen® for Safer Chemicals Benchmarks

GreenScreen® for Safer Chemicals is the tool used 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 finding safer alternatives to the most hazardous substances.

All substances achieving a GreenScreen benchmark are assessed by licensed profilers accredited by Clean Production Action to carry out Green Screen Assessments. In TCO Certified, substances achieving a GreenScreen benchmark 2 or better are accepted for compliance with the criteria for non-halogenated substances.

Benchmark 4
Few concerns
Benchmark 3
Slight concern
Improvement possible
Benchmark 2
Moderate concern
Use but search for substitutes
Benchmark 1
High concern
Insufficient data to assign a benchmark
