About Certified Green

Green Building is the Future of Building Construction and Interior Furnishings in the United States and Internationally


What Is Certified Green?

Certified Green is a registered trademark of Materials Analytical Services, LLC (MAS). 


This “green leaf” mark was created so consumers could readily identify interior construction products, furniture and furnishings which have been thoughtfully designed and manufactured to dramatically lower chemical emissions released into the indoor environment.


Reduced Volatile Organic Compounds (VOCs) = Healthier Air

In response to the US EPA and Consumer Product Safety Commission concerns over health effects stemming from increased exposures to volatile organic compound (VOC) emissions inside buildings, schools and residences, regulators and  industry groups worked to develop standards to dramatically reduce and in some cases eliminate the release of hazardous chemicals from construction products and furniture.  As with many environmental issues, the State of California Department of Public Health (CDPH) was one of the first groups of scientists to look at and develop a test methodology to determine what types of chemicals are released from common building products. This gave birth to Section 01350, which has since been adopted and referenced by the:

  • U.S. Green Building Council's LEED Rating system

  • Collaborative for High Performance Schools (CHPS)

Other industry organizations like the Carpet and Rug Institute (CRI) and the Business + Institutional Furniture Manufacturers Association (BIFMA) have built on the concerns related to VOC emissions and developed additional testing protocols and standards in those industries.  It's impossible today to read a paper or watch a newscast and not encounter the term “Green” as a metaphor for sustainability, environmental stewardship or improved indoor air quality. 


The MAS Certified Green® program integrates the rigorous product testing requirements of the CDPH Standard Method V1.2, the BIFMA M7.1 Test Method and Formaldehyde emission testing requirements of the Cal EPA – ARB with the conservative chemical emission limits referenced by the USGBC LEED, CHPS and CARB organizations.  There simply is not a more conservative or rigorous IAQ - product testing program available.  The MAS Certified Green® program is ISO/IEC 17025 and 17065 compliant and recognized by LEED, CDPHBIFMA and CHPS. 


Certification Verification, Complaints and Appeals

For inquiries regarding IAQ product certification, interested consumers and end-users can refer to the active product listings of MAS Certified Green® compliant products in four broad categories (Furniture, Flooring, Construction Materials, and Paints & Finishes) by clicking here. For questions regarding products not listed on-line or for previously certified products, requests can be made by contacting us at 770-866-3200 or at info@mastest.com.


For complaints regarding potential fraudulent use of the MAS Certified Green® name and/or mark or product certification appeals or technical inquiries relative to evaluation procedures and rules for granting, maintaining, extending, reducing, suspending, withdrawing or refusing certification can be made by contacting Bob Schmitter, 

Emissions Department Manager at 770-866-3212 or at bschmitter@mastest.com. Transparency is the cornerstone of integrity and non-bias product certification under the MAS Certified Green® program.
