Press Releases 2013

Our CO₂ emission factor in FY2011 based on the "Act on Promotion of Global Warming Countermeasures" was 0.406kg-CO₂/kWh (a 12% decrease compared to the previous year) with Kyoto mechanism credits, etc. taken into account. Consequently, our 5-year average CO₂ emission factor over the period from FY 2008 to FY 2012, to which our self-imposed target applies, is expected to be 0.377kg-CO₂/kWh (an 0.8% decrease compared to FY 1990).

In FY 2012, our CO₂ emission was 141.2 million tons (a 14% increase compared to the previous year) since power generated by thermal power generation increased due to the shutdown of nuclear power stations although the electricity sales was at almost the same level as that in the previous year. However, as we reflected Kyoto mechanism credits, etc., corresponding to 32.1 million tons, we saw a decrease in CO₂ emission factor compared to the previous year.

We set a self-imposed target, which is "to reduce our CO₂ emission factor (the five-year average CO₂ emission factor) by 20% compared to FY 1990", and made efforts to achieve this target. However, we do not expect that we can achieve the target even when an additional credit that will be issued later for FY 2012 is reflected in the comparison against the self-imposed target.

The CO₂ emission factor in FY 2012 will be announced as "actual emission factor, adjusted emission factor, etc., per electric utility company" after the government review.
