What is embodied carbon in timber construction?

Embodied carbon refers to the greenhouse gas emissions associated with the manufacture, transport, installation, maintenance, and end-of-life processing of building materials — everything except the operational energy use of the building. For timber, this includes emissions from forestry operations, sawmilling, kiln drying, transport, and any chemical treatments.

For timber, this includes emissions from forestry operations, sawmilling, kiln drying, transport, and any chemical treatments. Uniquely among structural materials, timber also stores biogenic carbon (CO₂ absorbed during tree growth), which can offset or exceed the production emissions.
