 For example, aboveground biomass resulting from land use changes can currently be converted to recognised emissions credits under the Kyoto Protocol Clean Development Mechanism (CDM).Increases in soil carbon for reasons other than reforestation either through changes to land management practices or through the burial of biochar are currently not included in emissions credit systems such as the CDM.These certificates of legal title can be traded as a form of currency independently of their use as an offset, yielding additional economic benefits.
