Making 90% of our new buildings from wood, rather than concrete and steel, could cut global CO2 emissions by 4% - more than the climate footprint of flying. How? Growing trees absorb carbon dioxide from the air and when used in construction, that CO2 remains stored in the wood 鈥� carbon captured in your beams, floors and walls. Now, treated timber can be versatile enough to build housing estates and strong enough for skyscrapers 鈥� or 鈥減lyscrapers鈥�. Tom Heap explains how it all works 鈥� and explores the benefits of living in a more wooden world.
