Under the Kyoto Protocol Japan committed itself to cutting emissions by 6% from 1990 levels in the 2008-2012 period. Absolute CO2 emissions have risen by nearly 15% from 1990 to 2006 [ 14]. The actual 2020 target is equivalent to a cut of 8% below 1990 emission level. Nevertheless climate policy may change due to the recent elections in Japan. In September 2009 the new Prime Minister announced plans for a commitment to reduce national emissions by 25% by 2020, relative to 1990, and to implement a cap-and-trade system within the Japanese economy.
