What is required for a product to count towards the "Sustainable Materials" credits?

For a product to contribute towards the "Sustainable Materials" credits, it is essential that it is backed by documentation proving the sustainability and regenerative sourcing of the materials. This is critical in the LEED framework because it helps building projects ensure that the materials used have been sourced in a manner that is environmentally responsible and socially equitable.

Sustainable sourcing often includes criteria such as using materials that are renewable, recycled, or have a low impact on the environment during their lifecycle. Documentation can include certifications from recognized standards or other verified claims that showcase a product's sustainability features. This promotes transparency and encourages manufacturers to adhere to better environmental practices.

Given the context of LEED, the importance of this documentation is to substantiate the sustainability claims made by manufacturers and to inform designers and buyers about the properties of the materials they are selecting for their projects.
