Publication discusses research-based principles of forest carbon accounting

Forests can potentially contribute to efforts to mitigate greenhouse gas emissions. Thus, it is important to account for carbon within forest ecosystems and changes in forest carbon stocks when developing climate change policy.

For more than a year, a team of experts appointed by the Society of American Foresters, including Reid Miner of NCASI, has been working to review and summarize the science on forest carbon accounting. The results of that review are now available in a publication titled “Forest Carbon Accounting Considerations in U.S. Bioenergy Policy.” The abstract from the review follows.

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 CO2 emissions, although it is long-term cumulative CO2 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 CO2 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.
