Pharos provides resources to assess human and environmental health hazards of chemicals and building materials, and tools to collaborate to find safer alternatives. Products listed in the Pharos database are evaluated based on a range of criteria, including their potential impacts on human health (e.g., toxicity, emissions), environmental impact (e.g., resource depletion, energy use), and overall sustainability performance. The Pharos Project promotes transparency by providing clear and accessible information about the materials listed in its database.
