The Healthy Building Network and Cascadia Green Building Council groups collaborated to develop the Pharos Project and the Living Building Challenge Red List of building products to avoid. That effort has evolved into a new initiative with BuildingGreen called the Materials Research Collaborative. The Collaborative is working toward developing a new open standard for reporting called a Health Product Declaration (HPD), that will complement Environmental Product Declarations and Life Cycle Assessments. The HPD would address product content and health information in a standardized reporting protocol.
