REDUCE EMBODIED CARBON

MRc2

1–4 points: A 10% reduction of embodied carbon is required for LEED Platinum projects.

INTENT

To reduce the embodied carbon impacts of materials used in commercial interiors projects.

REQUIREMENTS

Achievement pathways	Points
Commercial Interiors	1–4
Option 1. Reduce Embodied Carbon of New Materials	1–4
AND/OR
Option 2. Interiors Life-Cycle Assessment	1–4

Option 1. Reduce Embodied Carbon of New Materials (1–4 points)

Points are awarded according to Table 1. In dustry averages for material categories are defined by the U.S. Environmental Protection Agency, the most recent Carbon Leadership Forum Material Baselines report, or similarly robust and widely recognized publications and industrywide environmental product disclosures applicable to the project region.

Projects must track the GWP/unit of the materials installed, reconciling the design-phase embodied carbon intensities if materials or GWP values have changed. The reconciliation of material quantities is not necessary unless quantities have changed more than 10% from design through construction.

Projects must use project-specific material quantities and identify product-specific or facilityspecific Type III EPDs for covered materials to demonstrate reductions. Biogenic carbon may only be included for calculations that include C-stage emissions.
