| EXPO-roof saves 4238 tons of carbon¶  Deutsche Messe AG has decided consciously to realize its EXPO-roof with timber. Thereby an active contribution to climate protection was made. On LIGNA HANNOVER 2009, world fair for the forestry and wood industries, a statement and a documentary sign were given to Deutsche Messe AG by the director of the Advisory board for timber of North Rhine-Westphalia, Matthias Eisfeld. The amount of carbon saved by timber is for "wood-laymen" often surprisingly. To emit this amount of carbon saved by the EXPO-roof, a car has to cover a distance of about 22 million km, that would be 700 times around the world. By way of comparison: a person in Germany produces in the annual average about 10 tons of carbon. This amount is essentially made up of fumes by car-driving, heating-up the apartment and consume of electricity.Carbon dioxide is split during the process of photosynthesis in the leaf. The carbon C remains in the wood while the oxygen O is released into the atmosphere. Through this process the amount of carbon in the atmosphere is reduced for the period of use and the carbon is deposited in the wood. Sustainable forestry is, of course, a precondition. As it is complied in Germany for several centuries. For every tree felled, a new one is planted. And it is not allowed to take more wood out of the forest as grows again in the same time. That´s why the use of timber is active climate protection! Consequently the increased use of timber agrees the personal carbon-balance and the environment is intensified disburdens. write your comments about the article :: © 2009 Construction News :: home page |
