On November 19, the U.S. Environmental Protection Agency (EPA) released its revised Framework for Assessing Biogenic CO2 Emissions from Stationary Sources. The Framework reflects the findings and recommendations from reviews of a prior draft document. The EPA is now requesting a peer review of the revised Framework. The document continues to reflect the complexity involved in establishing a methodology to calculate the impact of biogenic emissions. Biomass stakeholders are encouraged to review the state guidance memo and the Framework report at the EPA’s website: http://epa.gov/climatechange/ghgemissions/biogenic-emissions.html.
