Substance types
  • FR = Flame retardant
  • PL = Plasticizer
  1. Interchangeable CAS numbers
  2. Assessment is freely available here
  3. Assessment is freely available here
  4. The benchmark is altered from 2 to U after a re-classification of the carcinogenicity endpoint. A valid assessment report must be submitted or this chemical will be removed from the accepted substance list on the set sunset date.
  5. Trade name specific benchmark in accordance to polymeric criteria in GreenScreen v1.4 for organic substances. Other trade names for the same CAS# number must provide a separate GS assessment since any relevant production impurity can impact the final benchmark.


All substances on this list have been reviewed and the benchmark set by Licensed GreenScreen profilers. For assessments that are not freely available, please contact the Licensed GreenScreen Profiler (Profiler) who conducted the assessment to purchase access to the completed assessment.

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
