How is LBC compliance determined?

The Living Building Challenge (LBC) indicator in Portico indicates whether the product is LBC Red List-Free according to the content inventory submitted in Portico. To be considered Red List-Free, a product record must have:

  • All contents disclosed to a disclosure threshold of 100ppm
  • No unrecognized substances (all must be identified by CASRN, or matched to a biobased or unregistered substance in the Pharos Chemical and Material Library)
  • No substances listed on the Living Building Challenge Red List

Red List compliance is shown at the substance level by an indicator with the abbreviation "RL." A green checkbox indicates compliance, a red "x" indicates the substance is listed on the Red List, and a grey question mark indicates that the substance is unrecognized and therefore compliance cannot be determined. If no Red List substance is listed but any unrecognized substance is listed, the product's overall LBC Red List-free indicator will display as "Unknown."

Declare labels are not incorporated into the LBC Red List-free indicator, as not all Declare labels indicate that a product is Red List-free. However, where available, a Declare label may be found in the Verification and Public URL section of a product profile.

Portico has enabled specific support for LBC exceptions as part of the exception types available to project teams. Exception types may be edited at the global level (across all projects) by partner administrators, or at the project level by project administrators. To enable LBC red list exceptions on a product, create an exception type with the special condition selected for "Requires identifying relevant red list exception type." Projects using default exception types may already have this option enabled under an exception type labeled "Not compliant with 3rd party standards."
