What are regional materials and why is it valuable?

• A. Materials sourced from within a region; reduces transportation emissions and supports local economies.
• B. Materials imported from overseas for better quality.
• C. Materials that are regional branding only.
• D. Materials that are not allowed in LEED projects.

Answer: (A)

Regional materials are materials that are extracted, processed, and manufactured within a defined geographic region near the project site. The value lies in lowering transportation energy and emissions by reducing how far supplies have to travel, which helps shrink the project’s embodied carbon. It also strengthens the local economy by supporting nearby suppliers and workers, contributing to a more resilient regional supply chain. In LEED, using regional materials helps demonstrate a lower environmental footprint and supports transparency about where materials come from.

Other ideas miss the point: importing from overseas increases transportation impacts; focusing only on branding ignores the actual sourcing location; and saying regional materials aren’t allowed in LEED is incorrect—the concept is actively encouraged to earn credits.
