Housing 90% of the world's population in timber buildings by 2100 could cut additional carbon dioxide in the atmosphere by the equivalent of roughly 20 times U.S. annual emissions from energy use, according to German researchers. To achieve that reduction however, tree plantations covering an area as big as Alaska would have to be created.
Continuing conventional construction could "claim 35–60% of the remaining carbon budget associated with limiting the global temperature increase to below 2°C", according to a paper by Potsdam Institute for Climate Impact Research, published in Nature Communications.
