Red Listed Products

Living Building Challenge Version 2
Acceptance is growing for a "Red List" of materials that are considered environmentally hazardous. The Red List, created by Living Building Challenge, precludes usage of the following:
  • Asbestos
  • Cadmium
  • Chlorinated Polyethylene and Chlorosulfonated Polyethlene
  • Chlorofluorocarbons (CFCs)
  • Chloroprene (Neoprene)
  • Formaldehyde
  • Halogenated Flame Retardants
  • Hydrochlorofluorocarbons (HCFCs)
  • Lead
  • Mercury
  • Petrochemical Fertilizers and Pesticides
  • Phthalates
  • Polyvinyl Chloride (PVC)
  • Wood treatments containing creosote, arsenic or pentachlorophenol
These compounds are found in many building materials; finding and adopting suitable alternatives will require a significant investment for many manufacturers.

The investment may be worthwhile, however, since the number of developers prohibiting Red List materials is increasing. For example, Google is among organizations that have banned the use of Red List products. Google is alleged to be building facilities at the rate of 40,000 sq. ft. a week.

Anthony Ravitz, Google’s project coordinator for real estate and workplace services, says the firm's decision is based on an economic analysis of the true costs of using a material, including the health and vitality of its employees and avoiding expensive claims for illness due to exposure to potentially dangerous materials. He calls upon manufacturers to provide better transparency about what is in their products, saying, “We don’t have complete information about what’s in our products. It’s not readily available. Until we have that, it will be difficult to make the best decisions.”
