What about the land use impact of timber production?

Timber production requires significantly more land than steel production per unit of structural material. A typical 5-storey timber building uses approximately 500 m³ of timber, requiring roughly 2–3 hectares of managed forest over a 70-year rotation.

Timber production requires significantly more land than steel production per unit of structural material. A typical 5-storey timber building uses approximately 500 m³ of timber, requiring roughly 2–3 hectares of managed forest over a 70-year rotation. However, this land simultaneously provides ecosystem services (carbon sequestration, biodiversity habitat, water filtration, recreation) that steel production land (mines, steelworks) does not. In sustainably managed forests, the land is continuously productive — each harvest is followed by replanting, creating a perpetual cycle. The key question is whether forest management is sustainable, not whether land is used.
