|---|---|---|---|
| All | Embodied Carbon | All | Bill of Materials (worksheet) that lists the quantities of major structure, enclosure, and hardscape materials used in the project, along with the cradle-to-gate (A1–A3) embodied carbon emissions for each material. Provide a description of the data sources used to determine the embodied carbon values for each material. Include justification of used baselines (regional, industry, similar construction type, etc.) if EPA GSA, CLF, or other recommended embodied carbon values are not available. Projects using life-cycle assessment or embodied carbon software tools may report the results from their tool. |
| All | Embodied Carbon | All | Provide alternative documentation if EPDs are not available. |
| All | High- Priority Embodied Carbon Sources | Document the top three high-priority embodied carbon sources and describe the solutions considered to reduce the impacts. |
