How much embodied carbon is saved by reusing timber?

Reusing structural timber saves approximately 500–700 kg CO₂ equivalent per cubic metre compared to using new timber (which itself has negative embodied carbon due to sequestration). The saving comes from: avoiding harvesting and processing energy (50–80 kg CO₂/m³), maintaining carbon sequestration in the timber (200–210 kg CO₂/m³ stored), and avoiding the production of alternative materials that would be needed if the timber were not reused (substitution benefit of 300–500 kg CO₂/m³).

Timber reuse is one of the highest-impact circular economy strategies available in construction.
