Material Transparency
Material transparency allows building professionals to research hidden product impacts like embodied carbon, toxic ingredients or byproducts, and social responsibility in the supply chain.
Manufacturers may release many types of documents in order to facilitate transparency. These include:
-
Environmental product declarations (EPDs), which show the environmental impacts of producing and disposing of a product
-
Health product declarations (HPDs), which disclose ingredients and their toxicity profiles
-
Corporate sustainability reports, which look at the overall environmental impacts of a whole company
