Comply with the following requirements:

Embodied Carbon

• Quantify the embodied carbon impacts (global warming potential or GWP) of the structure, enclosure, and hardscape materials for the project. All ancillary structures, such as parking structures or outbuildings within the LEED project boundary, must be included in the calculations. At a minimum, include asphalt, concrete, masonry, structural steel, insulation, aluminum extrusions, structural wood and composites, cladding, and glass.

• Quantify the cradle-to-gate (A1–A3) embodied carbon emissions for each material, defined as the product’s GWP/unit times the amount of material used.

o Alternatively, projects using life-cycle assessment or embodied carbon software tools

may report A1–A3 results from their tool.

AND

High-Priority Embodied Carbon Sources

Identify the top three sources of embodied carbon on the project and describe how projectspecific strategies were considered to reduce the impacts of these hot spots.
