UL GREENGUARD Certification Program

Products that have achieved GREENGUARD Certification are scientifically proven to meet some of the world’s most rigorous third-party chemical emissions standards, helping to reduce indoor air pollution and the risk of chemical exposure.

Overview

The majority of everyday chemical exposure in people occurs through the air we breathe in our homes, offices, schools and other indoor environments. These airborne chemicals are commonly referred to as volatile organic compounds (VOCs), which are used to manufacture and maintain building materials, interior furnishing, cleaning products and personal care products.

Studies by the U.S. Environmental Protection Agency (EPA) and other researchers have found that VOCs are common in indoor environments and that their levels may be two to a thousand times higher than outdoors.

UL GREENGUARD Certification Mark

There may be anywhere from 50 to hundreds of individual VOCs in the indoor air at any one time. Some may produce objectionable odors at low levels, but many have no noticeable smell. Many VOCs are irritants and can cause headaches, eye, nose and throat irritation, and dizziness. Long-term exposure to certain VOCs may lead to chronic diseases or cancer. At high concentrations, some VOCs are toxic.

The products that we use to build and furnish our indoor environments can have a significant impact on indoor air pollution levels. Products that have achieved GREENGUARD Certification are scientifically proven to meet some of the world’s most rigorous, third-party chemical emissions standards, helping to reduce indoor air pollution and the risk of chemical exposure, while aiding in the creation of healthier indoor environments.

Our UL GREENGUARD® Certification Program has established test methods and emission limits for these product groups:

  • Building materials, furniture and furnishings
  • Electronic equipment
  • Cleaning and maintenance products
  • Medical devices for breathing gas pathways 
Building products and furnishings

We offer two tiers of certification:  GREENGUARD Certification and GREENGUARD Gold Certification. All certified products are subject to a review of the manufacturing process and routine testing to help ensure minimal impact on the indoor environment.

GREENGUARD Certification

GREENGUARD Certification emissions limits were first used as purchasing specifications for the EPA and the state of Washington for furniture and commercial building products. GREENGUARD Certification criteria have been the basis for the LEED credit for low-emitting furniture since 2002. Office furniture products that are GREENGUARD Certified are also compliant with the Business and Institutional Furniture Manufacturers Association (BIFMA) X7.1 standard and BIFMA e3 credit 7.6.1.

GREENGUARD Gold Certification

The GREENGUARD Gold Certification standard includes health-based criteria for additional chemicals and also requires lower total VOC emissions levels to help ensure that products are acceptable for use in environments like schools and healthcare facilities. In addition to limiting emissions of more than 360 VOCs and total chemical emissions, GREENGUARD Gold Certified products must also comply with requirements of the state of California’s Department of Public Health (CDPH) “Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions from Indoor Sources Using Environmental Chambers, Version 1.2 (2017)” (also known as California Section 01350). Office Furniture products that are GREENGUARD Gold Certified are also compliant with the BIFMA X7.1 standard and BIFMA e3 credits 7.6.1, 7.6.2, and 7.6.3.

A summary of the allowable emission limits for GREENGUARD Certification and GREENGUARD Gold Certification is available.

Non-industrial 3D printers:

Medical devices for breathing gas pathways

UL GREENGUARD Certification for Medical Devices includes testing for VOCs, particulates and leachables in condensate, as well as a complete risk assessment that models expected exposure during use. This certification Standard was developed to be compliant with the ISO 18562, Biocompatibility Evaluation of Breathing Gas Pathways in Healthcare Applications, series of standards.

The ISO 18562 standard upon which the certification program is based is available from ISO.

Cleaning and maintenance products

Benefits

By choosing products with GREENGUARD Certification, you are creating a healthier indoor environment for your home, office or institution and reducing chemical exposure. GREENGUARD Certification Standards are among the most rigorous in the world, so you can be confident that these certified products live up to their claims.

Why UL

UL’s GREENGUARD Certification program is recognized and referenced in numerous building programs, standards and specifications around the world. Products with GREENGUARD Certification or GREENGUARD Gold Certification can contribute to the achievement of points in established green building rating systems, such as LEED, BREEAM, Fitwel and others, and satisfy code or ordinance criteria and meet indoor air quality specific request for proposal (RFP) requirements.
