Four research-based insights are essential to understanding forest bioenergy and "carbon debts." (1) As long as wood-producing land remains in forest, long-lived wood products and forest bioenergy ...reduce fossil fuel use and long-term carbon emission impacts. (2) Increased demand for wood can trigger investments that increase forest area and forest productivity and reduce carbon impacts associated with increased harvesting. (3) The carbon debt concept emphasizes short-term concerns about biogenic CO(2) emissions, although it is long-term cumulative CO(2) emissions that are correlated with projected peak global temperature, and these cumulative emissions are reduced by substituting forest bioenergy for fossil fuels. (4) Considering forest growth, investment responses, and the radiative forcing of biogenic CO(2) over a 100-year time horizon (as used for other greenhouse gases), the increased use of forest-derived materials most likely to be used for bioenergy in the United States results in low net greenhouse gas emissions, especially compared with those for fossil fuels.

On page 599 in the upper right hand column, the text should read, "...the estimated 100-year GWPs for biogenic CO2 from increased use of logging slash for energy are 0.23 and 0.49, respectively, ... ...meaning that the biogenic CO2 from these sources exerts 23 and 49% of the net radiative forcing of fossil fuel CO2 over 100 years."
