individual boards. Thus, no waste is created in the production of CLT BBS; the entire log is processed sensibly. As the wood additionally originates from forests that are kept under sustainable management, building solid timber houses is no problem for our forest either, quite the contrary even. Cultivated forests have even more CO2 storage capacity than non-cultivated forests, and thereby make an even bigger contribution to climate protection. 4,500 m³ of binderholz CLT BBS, i.e. the volume of CLT BBS that was installed in the Dalston Lane project, grows back in the Austrian forest alone within only 3 hours. If you build a solid wood house, you will not only give yourself a treat, but also do a good thing for the forest and the entire environment. Examples of CO2 storage in buildings If 10% of all houses in Europe were built of wood, the carbon emissions would reduce by an entire 1.8 million tonnes per year (rounded 2% of the entire carbon emissions). The devastating earthquake in L‘Aquila (Italy, 2009) cost 70,000 people their homes. They were to be reconstructed in high-quality and earthquake-proof construction design. binderholz CLT BBS emerged as the winner in the international tender procedure. Overall, 11,000 m³ CLT BBS were delivered and thus 29,600 m² of residential area were created. In the Austrian forest, 40 m³ of wood regrow per minute. Thus, it takes just 7 hours until the wood delivered to L‘Aquila had regrown in the Austrian forest. In these 11,000 m³, 25,300 tonnes of CO2 are bound for the long term. This is as much CO2 as 1,000 Europeans or 5,000 cars per year emit on average. Each cubic metre of wood that is used as substitute for other building materials, reduces the CO2 emissions in the atmosphere by 1.1 tonnes on average. When adding this to the one tonne of CO2 that is stored in the wood, approx. two tonnes of CO2 are stored overall in one cubic metre of wood.
