OVERVIEW
Materials really do matter to the health of occupants and the environment, but finding out what is in a product—and why—is not easy.
Products also have to perform as intended, so there are often tradeoffs between performance and the most sustainable materials.
Here you will find articles on:
-
the least hazardous, most environmentally sustainable materials used in products
-
environmental product declarations that can reveal the life-cycle impacts of materials
-
standards and third-party certifications that provide important VOC criteria and other health and performance metrics
-
chemicals of concern in building materials
You’ll also learn how what makes a product green can differ from product category to product category, and why multi-attribute vetting is critical no matter what product or material you’re selecting or specifying.
