Healthy Building Network (HBN) envisions a future in which all people and the planet thrive when the environment is free of hazardous chemicals. HBN's mission is to advance human and environmental health by improving hazardous chemical transparency and inspiring product innovation. As a non-profit organization, our work broadly benefits the public, especially children and the most marginalized communities, who suffer disproportionate health impacts from exposures to toxic chemicals. Since 2000, HBN has defined the leading edge of healthy building practices that increase transparency in the building-products industry, reduce human exposures to hazardous chemicals, and create market incentives for healthier innovations in manufacturing. We are a team of researchers, engineers, scientists, building experts, and educators, and pursue our mission on three fronts: 1) Research and Policy — uncovering cutting-edge information about healthier products and health impacts, 2) Data Tools — producing innovative software platforms that ensure product transparency and that catalog chemical hazards, and 3) Education and Capacity Building — fostering others' capabilities to make informed decisions. We work to reduce toxic-chemical use, minimize hazards, and eliminate exposure, especially to those chemicals of concern deemed unnecessary or which fail to improve product performance. We promote the development of affordable green chemistry solutions that support a healthy, successful, circular economy.
