How does MR guide material selection and waste in LEED?

• A. It focuses only on the color of materials.
• B. It eliminates all packaging.
• C. It promotes sustainable materials, reduction of waste, and responsible procurement across supply chains.
• D. It has no impact on procurement.

Answer: (C)

Materials and Resources (MR) in LEED is about choosing products that minimize environmental impact throughout their life cycle and supporting responsible buying practices across the supply chain. It promotes sustainable materials—emphasizing factors like recycled content, durability, low emissions, and regional availability—so selections reduce embodied energy and environmental harm. It also focuses on waste reduction through strategies such as construction and demolition waste management, reuse and recycling of materials, and designing for end-of-life recyclability. Across the supply chain, MR encourages responsible procurement—assessing supplier practices, transparency, and overall environmental performance—so decisions support broader sustainability goals. That combination—sustainable material choices, waste minimization, and responsible procurement—best captures how MR guides material selection and waste in LEED.
