UPDATE 1-Japan says energy-origin CO2 falls 6.7 pct last year

*Energy-origin CO2 makes up 90% of Japan greenhouse emissions

*Japan eyes minus 6% target (Adds details)

TOKYO, Oct 30 - Japan's emissions of energy-origin CO2, the main global-warming greenhouse gas, fell 6.7 percent to 1,138 million tonnes in the year to March 2009 from a year earlier, the trade ministry said on Friday.

In the year to March 2008, Japan, the world's fifth-biggest emitter, saw its emissions rise 2.3 percent to a record 1.37 billion tonnes in carbon dioxide (CO2) equivalent, of which 1,219 million tonnes was from energy-origin CO2 emissions, final data released by the government in April showed.

Japan's commitments to the Kyoto Protocol are to cut emissions to 1.19 billion tonnes on average in the five years to March 2013, down 6 percent from 1990 levels.

Energy-origin CO2 emissions, which are largely affected by industrial activities, account for about 90 percent of Japan's total greenhouse gas emissions.

Japan's plans to meet its minus 6 percent reduction goal include government spending on carbon offsets from abroad via the Kyoto Protocol's market schemes.
