From Wood Construction Goes Seriously Vertical. But Does it Really Sequester Carbon? First of all, it ignores recent research. They show the graph above from a study of an Oregon clearcut and repeat the information from a 1993 study that claims that harvested wood products sequester only 15% of site emissions as an excuse to completely ignore and discount the fact that wood sequesters carbon . Except that wood does sequester carbon, a lot of it. But as far as this article is concerned, it doesn't happen. Kyoto said so! (except in Kyoto they were not talking about construction,they were talking about carbon offsets.) They are only measuring the energy it takes to run an American clearcut operation and marking it up.
