ABSTRACT

The concentration of green house gas (GHG) in the global atmosphere is continuously increasing year by year, and the control of anthropogenic GHG discharge is becoming a very signifi cant problem for the human world. The Kyoto Protocol adopted by UNFCCC/COP3 requires IMO to make a GHG emission control plan of international sea transportation by 2005. This paper studies on some key issues such as emission index, control target, technological measures for CO2 emission control, etc. from the viewpoint of systems approach. The study indicates that emission factor EF, which is defi ned as the CO2 emission amount per unit transportation quantity, is appropriate for indexing the emission from ship. Regarding the emission control plan, the paper investigates some important issues from both technological and institutional aspects. The paper derives some useful formulas for EF, which represent clearly the effects of each component composing the ship system on EF. Those equations could be used for carrying out research and development systematically and effectively in order to improve the EF.
