The best path to a sustainable building is to know what’s in the materials being used to build it. However, questions remain among manufacturers and buyers about just how to evaluate and compare the environmental profiles of similar building products and materials. For example, what is the significance of a product bearing an eco-label? What are the differences between various types of product eco-certifications? What mechanisms exist to support comparisons between similar products? And, what steps can manufacturers take to bring environmentally preferable products to market as efficiently and as cost effectively as possible? This course will discuss each of these tools and how they can collectively provide information regarding the environmental impact of products, as well as their environmental performance, and offer an objective means of comparing similar products. Ultimately, these mechanisms enable buyers to make more informed decisions about the products they purchase, spurring further advances in product sustainability.
