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.
