How does timber help achieve net zero buildings?

Timber contributes to net zero buildings through a dual mechanism unique among structural materials: first, it has very low embodied carbon in production (processing emissions of 50–80 kg CO₂/m³ are far below steel at 1,500–2,000 kg CO₂/m³ or concrete at 200–400 kg CO₂/m³); second, it actively sequesters atmospheric carbon during growth, storing approximately 900 kg CO₂ per cubic metre of standing timber (210 kg CO₂/m³ remains stored in construction timber at service moisture content). This combination means timber construction can achieve negative embodied carbon — the structure itself becomes a carbon sink.
