GreenScreen Certified™

Frequently Asked Questions About GreenScreen Certified™

GreenScreen Certified™ is a new certification standard that promotes the use of inherently safer chemicals in products. The certification meets increasing demand for: a) safer chemicals in manufacturing and b) a simple platform that enables the communication of safer chemicals in products and formulations across supply chains. GreenScreen Certified is based on the GreenScreen® for Safer Chemicals, a globally recognized tool that identifies hazardous and safer chemicals through a rigorous benchmarking scoring system. GreenScreen Certified will be applied to different product categories, with the Textile Chemicals representing the first product application.

Catalyzed by Greenpeace’s “Detox Campaign” in 2013, the apparel industry is now a leading sector in redesigning manufacturing processes to be safer for people and the planet. Levi Strauss & Co., H&M, and the industry collaboration known as Zero Discharge of Hazardous Chemicals (ZDHC) are among the leaders in defining pathways to identifying and selecting inherently safer chemicals for use in the apparel sector. By reducing the hazards of chemicals in manufacturing, the industry reduces the risks of chemicals to workers, communities, and to a brand’s bottom line. 


How can apparel brands clearly communicate to suppliers their interest in safer chemicals and how can chemical formulators clearly communicate to brands their progress to safer chemicals in products? Needed is an independent, NGO-developed, and transparent hazard assessment framework that has widespread recognition in industry and acceptance among environmental groups.



Clean Production Action launched GreenScreen CertifiedTM Standard for Textile Chemicals to provide a clear and robust communication platform concerning chemicals in textile formulations. GreenScreen Certified enables formulators to communicate actions they are taking to help downstream partners manage regulatory and reputational risks related to chemicals and meet sustainability goals.  And GreenScreen Certified provides brands with the platform to communicate their preferences and requirements for safer chemicals in textile formulations.

GreenScreen for Safer Chemicals is a hazard assessment method that can be used to evaluate any chemical against 18 human and environmental health factors. A GreenScreen assessment of a chemical will result in the chemical being assigned one of five Benchmark™ (BM) scores: 1 (red), 2 (orange), 3 (yellow), 4 (green), or “U” for unspecified.


GreenScreen List Translator™ assigns a chemical a score based on information from over 40 authoritative and screening hazard lists developed by national and state governmental agencies, intergovernmental organizations, and NGOs. These lists include REACH categorizations and chemical hazard classifications by countries using the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). List Translator assigns a chemical one of four scores depending on the list(s) a chemical is on (or not on).



A GreenScreen Benchmark (BM) score is more rigorous than a List Translator (LT) score because a BM-score is based on a much more comprehensive set of toxicological data, while an LT-score is solely based on chemical hazard lists.

Formulators of textile chemicals can now have their products certified to one of three levels based on GreenScreen List Translator (LT) and Benchmark (BM) scores. The GreenScreen Certified Standard for Textile Chemicals uses LT- and BM-scores to specify three levels of progress to safer chemicals: Bronze, Silver, and Gold. Requirements by certification level for a textile formulation include:                            





1. Meet the requirements as specified by the Zero Discharge of Hazardous Chemicals Group B Manufacturing Restricted Substances List.
2. Contain no intentionally added chemical substances (greater than 0 ppm) or impurities (at or above 100 ppm) that have a List Translator score of LT-1. This means a formulation would contain no chemicals with an LT-1 score based on the assessment of each chemical ingredient against over 2,000 known chemicals of high concern listed on international chemical hazard listings.






1. Meet the requirements as specified by the Zero Discharge of Hazardous Chemicals Group B Manufacturing Restricted Substances List.
2. Contain no intentionally added chemical substances (greater than 0 ppm) or impurities (at or above 100 ppm) that have a GreenScreen BM-1 score. This means a formulation would contain no BM-1 chemicals as assessed using the GreenScreen for Safer Chemicals method.






1. Meet the requirements as specified by the Zero Discharge of Hazardous Chemicals Group B Manufacturing Restricted Substances List.
2. Contain no intentionally added chemical substances (greater than 0 ppm) or impurities (at or above 100 ppm) that have a GreenScreen score of BM-1 or BM-2.

GreenScreen Certified creates value for users because it:


  • Builds on the GreenScreen method.
  • Establishes three levels of certification for textile formulations that specify increasingly more stringent requirements for safer chemicals (based on hazard assessment).
  • Integrates ZDHC’s MRSL into all three levels of certification.
  • Provides a clear platform for communicating chemical hazards in products across supply chains.
  • Allows transparency around chemical hazard, while protecting proprietary formulations.
  • Is developed and maintained by Clean Production Action, an independent, mission-driven NGO that creates strategies and solutions for safer chemicals.



GreenScreen Certified enables:



  • Brands to clearly specify their preferences and requirements for safer chemicals in textile formulations.
  • Formulators of textile chemicals to visibly promote their:
    • avoidance of known chemicals of high concern, List Translator (LT)-1 chemicals and
    • use of safer chemicals (no GreenScreen BM-1 and/or BM-2 chemicals) to brands and the public.


GreenScreen Certified provides a clear, new and transparent B2B communication tool on chemical hazards in textile formulations.   

Step 1: Registration: Determine if your products fall within the program’s scope – commercially available chemical formulations used in textile manufacturing. Sign into to register your company and receive details on the Standard for Textile Chemicals.


Step 2: Choose Service Provider:



a. Select third-party GreenScreen Certification Service Provider.



b. Submit product inventory information and documentation to your GreenScreen Certification Service Provider. This will require identifying the chemicals intentionally added to the formulation (by weight percent) and presence of any impurities on the ZDHC MRSL. Use the product inventory form to compile information on chemical ingredients in your product(s). See the GreenScreen Certified™ Standard for Textile Chemicals for all requirements.



c.Service Provider provides you with a Verification Summary Report for each product.



Step 3: Verification:



a. Submit your completed Verification Summary Report to Clean Production Action.
b. Clean Production Action verifies information and certification level.



Step 4: Licensing:



a. Applicant signs License Agreement and pays fee for certification.
b. Clean Production Action issues Certificate for the certification level achieved and signs license agreement, which includes rights for use of the logo.



Certificates last for the duration of the version of the standard.

The estimated time frame is one to four months, depending on certification level, preparatory work done prior to submitting information to a Service Provider, and availability of Service Providers.            

Costs will vary depending on:


  • Certification Level. For example, Bronze certification will require less time and expense than Silver or Gold.
  • Number of chemicals that must be assessed.
  • Number of products assessed.
  • Fees charged by GreenScreen Certification Service Provider.

All formulators and their products are published on our registry, which includes the products, manufacturers, and level to which they are certified. Clean Production Action will also regularly publish newsletters, press releases, and social media posts promoting GreenScreen Certified™.

Analytical testing is not required; however, if analytical testing was used to determine the identity and/or concentration of any substance listed in the Product Inventory Form, the Applicant must provide a copy of up-to-date analytical test results from an accredited laboratory to qualify for certification.

Yes. Products must meet the Zero Discharge of Hazardous Chemicals (ZDHC) Group B manufacturing restricted substances (MRSL) list to qualify for any level of the GreenScreen Certified™ Standard for Textile Chemicals. This list is maintained by ZDHC and specifies allowable limits for certain substances. Substances not listed on the ZDHC Group B mRSL must be disclosed and assessed GreenScreen if present at > 0 ppm (> 0%) for intentionally added substances and ≥ 100 ppm (0.01%) for impurities.

No. To ensure all inventory and MRSL thresholds are met, third-party GreenScreen Certification Service Providers may need to work directly with an Applicant's suppliers to obtain proprietary data, however. See the Product Inventory Form for a full list of required documentation.
