Abstract
This discussion paper is for the policy makers and researchers to have better understandings on the specific content of the international collaboration project on global warming mitigation, the nature of the negotiation between the host and the investor, and the policy correspondence by the government. To do so, first, this paper has sorted out the issues such as the baseline related to the economic evaluation of greenhouse gases (GHGs) emission reduction project (i.e. estimation of GHGs emission reduction amount and cost). Second, the economic evaluation of the actual Activities Implemented Jointly (AIJ) project between China and Japan has been made. From the results of it,various issues relating to the estimation of the specific size of the GHG emission reduction cost and amount through negotiation have become apparent. Third, by the monetary valuation of the local emission reduction effect of an air pollutant (Sulfur Dioxide:SO2) of this AIJ Project, it has quantitatively indicated the rise of the project’s economic value. Finally, along with the presentation of the author’s opinion relating to the specific type of the project expecting investments, appropriate policies, especially by the Japanese Government to deal with the global warming mitigation projects, and the specific input method of public funds have been discussed.
