What is Embodied Carbon?

Embodied carbon is the greenhouse gas emitted producing, transporting, and installing building materials — the carbon 'baked in' before the building operates a single day. As operational energy gets cleaner, embodied carbon becomes the dominant share of a building's lifetime footprint.

In practice

Teams measure it by attaching emission factors (from EPDs) to quantities, then reduce it through material choices — lower-carbon concrete mixes, mass timber, reuse. Estimating tools increasingly report carbon next to cost from the same takeoff.
