What is the definition of "regional materials" in LEED?

The definition of "regional materials" in the context of LEED refers to materials that are extracted, processed, and manufactured within a certain distance from the project site. This definition emphasizes the importance of sourcing materials locally, as it supports local economies, reduces transportation emissions, and decreases the overall environmental impact associated with shipping materials over long distances. By encouraging the use of regional materials, LEED promotes sustainable practices and resources that can be readily available for construction projects while fostering community engagement and development.

Options focusing on foreign-sourced materials, recycled or salvaged materials, or large-scale production do not align with LEED's specific focus on the proximity of material sourcing to the project site. These alternatives may have their own merits in sustainability, but they do not capture the essence of what qualifies as "regional materials" within the LEED framework. By recognizing and prioritizing regional materials, LEED contributes to the broader goals of sustainability and reduced carbon footprint in building practices.
