Which LEED knowledge domain addresses the sustainable sourcing of materials and waste management?

• A. Indoor Environmental Quality
• B. Energy and Atmosphere
• C. Materials and Resources
• D. Regional Priority

Answer: (C)

Sustainable sourcing of materials and waste management is addressed in the Materials and Resources domain. This domain focuses on how building products are selected and sourced, including the environmental impact of extraction, manufacturing, and transport, as well as how waste is managed—from construction and demolition waste to overall materials optimization and reuse. It covers strategies like selecting products with transparent ingredient information, pursuing recycled content, using regional materials to reduce transportation impact, and implementing construction waste management plans to divert waste from landfills. In contrast, other domains target different concerns: indoor environmental quality centers on occupant health and comfort; energy and atmosphere focuses on energy use and emissions; regional priority highlights region-specific issues but not the broad scope of materials lifecycle and waste. So, the correct domain is Materials and Resources because it governs the sustainable sourcing of materials and how waste is handled.
