CO_2 UNDERGROUND SEQUESTRATION AND GREENHOUSE GASES MITIGATION IN JAPAN

摘要

In June 2002, Japan ratified the Kyoto Protocol this committing it self to reducing its GHG emissions between 2008 and 2012 by 6% to below the 1990 emissions level. Since then the Japanese government has paid special attention to policies and measures for GHG reductions through fuel switching, land-use and forest management, as well as improvements in energy efficiency and implementing CO_2 underground storage technology. This paper presents the CO_2 gas in first order and other GHG emissions in Japan trough time and in different economic sectors, it then goes on to the different abatement methods needed to achieve the UNFCC goal of atmospheric greenhouse gas concentrations stabilization with a particular emphasis placed on CO_2 underground storage projects. We quote two CO_2 underground sequestration pilot projects; one is the two-year enhanced coal bed methane recovery project in the Ishikari coal basin in Hokkaido and the other is the five-year CO_2 sequestration with enhanced gas recovery pilot project in an active natural gas field located at Iwanohara Base in Nagaoka City, Niigata Prefecture.
