Abstract:

Issues with regard to the uncertainty in estimating the net anthropogenic greenhouse gas removals by sink are discussed through analyzing the process that the sources of uncertainty generate in estimating the net anthropogenic greenhouse gas removals by sink and the uncertainty of the sources. The approaches and proposes for quantifying the uncertainty of sources and the uncertainty in estimating the net anthropogenic greenhouse gas removals by sink are put forward in this paper. We intend to provide help for investors in deciding prior efforts to improve the accuracy of approach in future and in choosing proper methodologies.

Key words: clean development mechanism (CDM), afforestation and reforestation, the net anthropogenic greenhouse gas removals by sinks, uncertainty
