In almost all areas of building, wood and wood-based materials are regarded as a “sustainable” product. Wood is also generally cost-effective, lending itself to prefabrication, easy processing and resource-saving methods of building. In addition, thanks to its thermal properties and the way it responds to moisture, wood has a positive effect on indoor air quality. As regards its environmental life cycle assessment, the arguments in favour of wood are persuasive, as building in wood is regarded as environmentally compatible and climate-neutral. Trees take up carbon dioxide from the atmosphere and store it in the wood as carbon. This carbon remains in the wood product after processing. And, although processing does cause CO² emissions (generating the process energy required and producing the adhesives), the quantity is normally smaller than that which is locked in the wood.
