Japanese Target on Global WarmingJapanese Target on Global Warming
( By METI)
p Under the Kyoto Protocol, Japan has a target to reduce GHG emission up to 6%relative to the levels pertaining in 1990, to be achieved on an annual basis from 2008 to 2012.
p CO2 emissions originated by energy represent 90% of total greenhouse gases.
