Abstract: The amounts of CO₂ sequestrated and CO₂ emission reduced are compared and estimated in the rare forest sustainable management project in Hubei Province by using the biomass,forest volume regression model and carbon content conversion.The project is expected to sequestrate 234792.44t of carbon in the 25-year crediting period,equivalent to 860905.61t of CO₂ emission reduction,which is 6.5 times the CO₂ emissions generated from the project activities.The implementation of the project therefore will play an important role in reducing emissions.

Key words: rare forest, forest carbon sink, Hubei Province
