In the case of biomass gasification power generation technologies in Guangdong province as CDM project,for example,based on the three baseline determined in this research and applying the incremental cost analysis approach,the unit carbon-mitigation cost of middle-size biomass gasification power generation was calculated,and the sensitivity was also analyed at same time.

In this research,the application of the co-combustion technology of biomass with coal for power generation in Guangdong is used as a Clean Development Mechanism(CDM) case to reveal the mitigation cost per unit carbon for the power generation by co-combustion under different proportions of fuel.
