The production and processing of wood uses less energy than most other building materials, giving wood products a very low carbon footprint. Wood can often be used in place of materials like steel, aluminum, concrete or plastics that require large amounts of energy to produce. This means that there are less carbon dioxide emissions associated with wood products than other major building materials.

Substituting a cubic metre of wood for other construction materials (concrete, blocks or bricks) could save up to 1 tonne of CO2 emissions.
