As a consequence the construction sector needs to move towards using renewable raw materials as swiftly as possible. Manufacturing of cement and use of concrete is very harmful to the climate on a global level. Cement production and the use of concrete are currently responsible for one tenth of all global CO2 emissions, which is why the greater use of wood in high-rise apartment buildings and in large constructions needs to be accelerated.<\/p>\n
If European house construction, currently based on concrete, was based on wood, the consumption of non-renewable natural resources in construction would be reduced by two-thirds; energy consumption from the manufacturing of building materials and construction halved and CO2 emissions cut more than by one half.<\/p>\n
Use of cement worldwide has grown steadily over the past 20 years and is now 4.200 million tons per annum. Cement manufacturing requires a great deal of energy and the production process also emits carbon dioxide as a result of a chemical reaction. Hence, the overall climate impact is substantial.<\/p>\n
