Embodied Carbon
“Embodied carbon” typically refers to the upfront greenhouse gas emissions associated with producing building materials.
Structural materials like steel and concrete tend to have the highest embodied carbon within a building, but all the other products, even down to interior finishes like drywall and carpet, come into play as well. To learn about the embodied carbon of a specific product, look to an environmental product declaration. A whole-building life-cycle assessment is necessary to understand the emissions associated with an entire project.
