Trees absorb and store billions of tonnes of carbon every day and all the products derived from wood - such as walls, windows, floors, doors, paper, desks and many more - keep on storing carbon throughout their lifetime. Studies show that more emissions are captured and stored in timber products than are emitted during harvesting, processing, manufacturing and transportation combined. For every metre cube of timber used across the supply chain, roughly one tonne of carbon is stored. That makes timber the only truly sustainable construction material. To have an idea, if we built 200,000 new houses in timber, we would store around 4 million tonnes of carbon dioxide every year!
