The Healthy Building Network was founded in 2000 on the initiative of leaders from the national environmental health movement based on this belief. There are many examples of the opportunities for change in the building materials market. The Healthy Building Network is deeply committed to the goal of achieving environmental justice. Since 2000, our projects have directly resulted in the introduction of new, healthier building materials into commercial markets, shifting over $4 billion in materials purchases from toxic materials to healthier alternatives that are comparable in both price and performance to the materials they have replaced.
