Carbon Storage &Greenhouse gas
Recent research by the Cooperative Research Centre for Greenhouse Accounting compared the amount of greenhouse gas emissions generated by the manufacture of timber products, with the amount of emissions generated by other common building materials.
The results showed that by substituting timber in the construction of a typical family home, greenhouse gas emissions equivalent to up to 25 tonnes of carbon dioxide, could be saved.
In order to produce 1kg of timber, a tree consumes 1.47kg of CO2 and returns just over a kilo of oxygen into the atmosphere.
When trees are harvested and used to make wood products, the carbon remains stored in the wood for the life of the product. About 50 per cent of the dry weight of wood is carbon.
It is far more preferable to have the carbon stored in trees and in wood products on the surface of the Earth than in the atmosphere, where it contributes to climate change.
Using wood to build long-lasting, efficient and durable homes and other buildings will help reduce the amount of carbon dioxide in the atmosphere. Wood has been one of the main building materials throughout human history.
Wood is the only building material that helps tackle climate change. It is important to remove carbon from the atmosphere as well as reduce new carbon emissions going into the atmosphere. Wood achieves both.
