News Finding: * About 12% to 19% of annual global fossil fuel consumption would be saved including savings achieved because scrap wood and unsellable materials could be burned for energy, replacing fossil fuel consumption.
Paper Finding: In efficient cases, less wood would be harvested than is growing, so the forests and harvest rates would be more than sustainable; in fact, the unharvested wood could accumulate in some forests and save even more CO 2 (forest pathway).
News Context: They found that increasing the wood harvest to the equivalent of 34% or more of annual wood growth would have profound and positive effects:
  
  * Between 14% and 31% of global CO 2 emissions could be avoided by preventing emissions related to steel and concrete; by storing CO 2 in the cellulose and lignin of wood products; and other factors. * About 12% to 19% of annual global fossil fuel consumption would be saved including savings achieved because scrap wood and unsellable materials could be burned for energy, replacing fossil fuel consumption. Wood-based construction consumes much less energy than concrete or steel construction.
Paper Context: Building with less efficient wood products also sequesters even more FF CO 2 , largely because less efficient products both use more product wood (storage pathway) and burn more scrap-wood and unmerchantable logs that displace more FF energy (energy pathway). In efficient cases, less wood would be harvested than is growing, so the forests and harvest rates would be more than sustainable; in fact, the unharvested wood could accumulate in some forests and save even more CO 2 (forest pathway). If none of the unharvested wood growth burned or rotted, CO 2 savings would be greatest by using wood for efficient building products, but not harvesting the excess that would only be used directly for energy.
