“Program valuation factor = multiplier assigned to each compliance program:
• GreenScreen benchmark. Products that have fully inventoried chemical ingredients to 100 ppm:
o All ingredients assessed using GreenScreen List Translator and have no Benchmark-1 hazards, 100% value (by cost)
o All ingredients have undergone a full GreenScreen assessment and have no Benchmark-1 scores, 150% value (by cost)
• Cradle to Cradle Certified version 2.1.1:
o Gold, 100% value (by cost)
o Platinum, 150% value (by cost)
• Cradle to Cradle Certified version 3.0:
o Silver, 100% value (by cost)
o Gold or Platinum, 150% value (by cost)
• REACH Optimization. This is an alternative compliance path for projects outside the U.S. If the product contains no ingredients listed on the REACH authorization or candidate list, value it at 100% of cost.”

Manufacturer’s Inventory
Manufacturers may publicly disclose all ingredients by name and Chemical Abstract Service (CAS) registry number. No third-party verification is required for this option, but the information must be publicly available; direct disclosure to the designer or contractor is not acceptable.
If a specific ingredient cannot be disclosed for proprietary reasons, the manufacturer may withhold the name and CAS registry number but still provide the following information:
• Role or function in the product
• Amount, as a percentage of total product content or ppm
• GreenScreen LT score (GS List Translator) or GS Benchmark score (full GS). Report hazard levels and hazard endpoints that result in scoring the ingredient as LT-1 or LT-P1 using GS List Translator (e.g. High for Carcinogenicity) or hazard levels and hazard endpoints that result in scoring the ingredient as Benchmark 1 using full GreenScreen. It is not necessary to report hazards associated with higher Benchmark levels or LT-UNK (Unknown) using GS List Translator.
All ingredients that constitute 0.1% (1,000 ppm) or more of the product must be accounted for. This threshold is 10 times lower than the typical 1% minimum threshold for reporting on a material safety data sheet (MSDS).
Health Product Declaration Open Standard
Disclosure is done through Health Product Declaration (HPD), which is an open standard for reporting product ingredients and their associated health hazards. Manufacturers that use HPDs must provide the nonproprietary information listed above (role or function, amount, and health hazards) for every ingredient, not just those whose names have been withheld. The manufacturer affirms “full disclosure of known hazards” on the front summary page and further affirms the level of disclosure with residuals/impurities. For the material to comply with the credit requirements, the HPD standards for the 1,000-ppm level must be attained and the appropriate box on the summary page checked.
An HPD is several pages long, with a one-page summary listing company information, metadata about the report, and ingredients, and continuing on subsequent pages with more detail about individual ingredients and their associated health hazards, plus details on any certifications and associated materials. GreenScreen List Translator scores and/or Benchmarks, if any, are listed for each ingredient in HPDs, in the contents section. A report from a certified GreenScreen profiler may also be used to document the GreenScreen benchmarks for a product’s ingredients.
Manufacturers that use the standard HPD format reduce uncertainty about whether the information that they have provided meets the credit requirements, and they create a report that should be useful in other settings as well.
Qualifying HPDs developed under the Open Standard version 1.0, 2.0, 2.1 or subsequent versions of the standard are eligible for documenting credit achievement if the HPD is still valid at the time that the product is purchased and used on a project.

GreenScreen Benchmark 1
The GreenScreen hazard assessment method evaluates individual chemicals. GreenScreen is based on a toxicological assessment that starts with a collection of authoritative lists of “chemicals of concern” published by governmental and nongovernmental organizations (GreenScreen List Translator). These substances are known to be associated with certain health problems. The assessment then proceeds to reviews of the scientific literature, use of structure activity relationship models and chemical analog data to fill data gaps (Full GreenScreen). Chemicals are assigned to one of four main categories: those of highest concern, as indicated in the authoritative lists, are assigned Benchmark 1. Chemicals that are not on the major authoritative lists and pass a toxicological review based on Clean Production Action’s protocols can be assigned benchmarks that indicate lower levels of concern; Benchmark 4 is the lowest level of concern. A full GreenScreen assessment overrides the results of screening using the GreenScreen List Translator only.
The GreenScreen List Translator has been automated by two software providers. It can be accessed through the Chemical and Material Library found in Healthy Building Network’s Pharos Tool, the ToxNot website, and in the GS List Translator module in the GreenWERCS software tool by The Wercs. The Interstate Chemicals Clearinghouse has created a website where GreenScreen assessments can be posted by various participating State governments and shared with no costs or restrictions. The GreenScreen Store is another source for some freely available full assessments: www.greenscreenchemicals.org/gs-assessments
Option 1 of this credit requires only the GreenScreen List Translator review of ingredients to ensure that none of the ingredients are on the authoritative lists and thus flagged as Benchmark 1 substances. Project teams should look for documentation from manufacturers that either identifies all ingredients in the product or identifies and characterizes any benchmark hazards.
Option 2 requires the Full GreenScreen toxicological assessment to ensure that none of the ingredients are Benchmark 1. Project teams should look for documentation from manufacturers that shows each ingredient in the product has been subject to a full GreenScreen assessment by a licensed GreenScreen Profiler and that the product contains only Benchmark 2 and higher ingredients.
Products using GreenScreen version 1.2, 1.3, or subsequent versions are eligible for documenting credit achievement if the analysis/scores are valid at the time that the product is purchased and used on a project.
For Manufacturers and Suppliers
GreenScreen’s List Translator assigns hazard classifications based on the various governmental and authoritative hazard lists including lists of chemicals classified using the Globally Harmonized System of Classification and Labeling. The GreenScreen List Translator can be used to identify chemicals that achieve or may achieve the Benchmark 1 level of concern. Under Option 1, manufacturers that keep certain ingredients proprietary must characterize any health hazards from those ingredients, as indicated by the List Translator or a full GreenScreen assessment.
Under Option 2, the manufacturer must warrant that no ingredients in the product at levels of 0.01% or more (100 ppm) are designated as Benchmark 1 chemicals based on the referenced lists defined by the List Translator. These products achieve compliance at the first level of the option.
The second level of compliance requires that all ingredients be Benchmark 2 or higher. There is no definitive List Translator for Benchmark 2, so manufacturers must engage an independent third party to screen all their ingredients, using the screening protocol defined by GreenScreen, and certify that none of them are Benchmark 1.
Products using GreenScreen version 1.2, 1.3, or subsequent versions are eligible for documenting credit achievement if the analysis/scores are valid at the time that the product is purchased and used on a project.

Example GreenScreen List Translator Result
The GreenScreen List Translator identifies each list that GreenScreen references, including its source, which hazards in the GreenScreen it covers, whether it is “authoritative” or “screening,” and which GreenScreen hazard level and subsequent Benchmark score applies, along with other data.
