How does LEED define 'sustainable materials'?

LEED defines 'sustainable materials' as those that have a reduced impact on the environment and health throughout their entire lifecycle—this includes production, use, and disposal. This definition emphasizes the importance of considering the environmental footprint of materials, which encompasses factors such as resource extraction, manufacturing practices, and end-of-life impacts. By focusing on the entire lifecycle, LEED promotes materials that not only minimize harm during their use but also encourage responsible sourcing and recycling or disposal practices, helping to create a healthier indoor environment and reduce overall resource consumption. This holistic approach aligns with the fundamental goals of sustainability, which are to protect both the environment and human health while driving innovation in materials choices.
