Why use ASTM D6866?
The global “green” initiative is to associate renewable biomass with either reduced greenhouse emissions (Kyoto Protocol) or energy produced from renewable biomass (UK Renewable Obligation Certificates). Since CO2 is a major atmospheric culprit (if not “the” atmospheric culprit), relating policy criteria directly to CO2 via ASTM D6866 is most appropriate. All guidelines, such as the Renewable Portfolio Standard as well as the Voluntary Reporting of Greenhouse Gases, allow you to remove biogenic CO2 directly from the cap.
