MAS Certified Green® has been accepted for Feature 04 Parts 1, 2, 3, 4, 5.
The MAS Certified Green® program integrates testing requirements of California Department of Public Health (CDPH) Standard Method V1.1, the BIFMAM7.1 Test Method and Formaldehyde emission testing requirements of the Cal EPA – ARB with chemical emission limits referenced by the USGBC LEED, CHPS and CARB organizations. The MAS Certified Green® program is ISO/TEC 17025 and 17065 compliant and recognized by LEED, CDPH, BIFMA and CHPS.

MAS Certified Green® is also accepted for LEED v4 EQ Credit Low-Emitting Materials Third Party Certifications and Labels. It meets CDPH for emissions, CARB or SCAQMD for VOC content (wet-applied), and ANSI/BIFMA for furniture.

GUT has been accepted for Feature 04 Part 3.

The GUT standard was created by the European carpet industry, and aims ""to improve continuously all environmental and consumer protection aspects throughout the life cycle of a textile floor covering (from production to installation, to use phase and recycling"".

This standard is only applicable to Part 3, and thresholds are as follows:

Termination criteria 3 days after loading:
TVOC: 250 µg/m³
Formaldehyde: 9 µg/m³

Desired values 28 days after loading:
TVOC: 100 µg/m³
Formaldehyde: 4 µg/m³

Previously published as an AAP:
Field and Laboratory Emission Cell (FLEC) emissions testing is approved as an emissions testing methodology only for furniture and furnishings that are made up of a uniform material and have flat testing surfaces on which the FLEC emissions testing methodology may be applied. For example, flat surfaced cabinetry that is made up of a uniform material may be tested using this methodology. However, chairs that are made from a variety of materials that lack flat surfaces may not be tested using this methodology. The emissions test must be administered by a third party investigator with no affiliation with the project. The associated costs are the responsibility of the project team. Additional tests performed in accordance with ISO 16000 methodology must be performed for total aldehydes and 4-Phenylcyclohexane and must meet the thresholds specified in the WELL Building Standard.

Previously published as an AAP:
The following referenced standards may be used in lieu of ANSI/BIFMA e3-2011 Furniture Sustainability Standard Section 7.6.1 and 7.6.2, testing in accordance with ANSI/BIFMA Standard Method M7.1-2011:
- the Finnish M1 label for non-upholstered furniture
- the Blue Angel label for upholstered furniture
If these standards are used, the furniture must also be separately tested for 4-phenylcyclohexane and total aldehydes and held to the same limits specified in ANSI/BIFMA e3-2011 section 7.6.1 and 7.6.2
