Recently especially after 1990, we have experienced so many natural disasters or abnormal climate changes which might have been caused by global warming. Now it became common understanding that the green house gas or CO2 emitted by the combustion of fossil fuel is the main cause of the global warming. Reflecting the economic growth and increase in population, the consumption of fossil fuel is expected to increase largely during this century especially by remarkable energy requirement in developing countries. Japan has committed to decrease GHG (green house gas) emission level by 6% compared with 1990 emission level at the 1st Commitment Period (2008-2012) given by the requirement under Kyoto-Protocol. On the other hand, Japan also has to meet the energy requirement needed during its term, even though the increasing ratio is so mild compared with the past or developing countries. However recent forecast expects GHG emission level at that time will exceed about 13 % over the 1990 level, which forces Japan to take further energy saving technologies such as adopting higher efficient gas turbine cycle. This paper explains the Japanese energy situation, future energy and demand prospect, and finally the outline how to meet the above mentioned CO2 emission target, focusing the importance of energy saving technologies.
