GreenScreen is a method for comparative chemical hazard assessment. It is used to assess the inherent hazards of chemicals and their potential effect on human health and the environment. The List Translator score (LT-) is a designation based on initial stand-alone screening of a substance against GreenScreen authoritative hazard lists. The Benchmark score (BM-) is a designation based on a full GreenScreen assessment, which includes a comprehensive review of all available information including 1) measured data from standardized tests and scientific literature, 2) estimated data from suitable analogs and models, 3) hazard lists. Both are free, public protocols; however, a full assessment used for a public claim must be completed by a licensed profiler. https://healthymaterialslab.org/tool-guides/hml-resources
