How much CO₂ does timber sequester per cubic metre?

Structural softwood sequesters approximately 0.7–0.9 tonnes of CO₂ per cubic metre of timber (depending on species density). This carbon remains locked in the timber for the lifetime of the building.

Structural softwood sequesters approximately 0.7–0.9 tonnes of CO₂ per cubic metre of timber (depending on species density). This carbon remains locked in the timber for the lifetime of the building. When combined with the low embodied carbon of timber production (typically 0.1–0.3 tCO₂e/m³), timber achieves a net negative carbon footprint — it stores more carbon than is emitted during its production and transport.

Why this matters

This question relates to Carbon Footprint of European Timber vs Steel vs Concrete, which covers the broader topic in detail. Understanding this specific aspect helps architects, builders, and timber dealers make informed specification decisions.
