Our CO₂ emission in FY2011 calculated based on the "system to calculate, report, and publicize greenhouse gas emission", etc. of the "Act on Promotion of Global Warming Countermeasures" increased by 13% compared to the previous year to 124.4 million tons.

With the Kyoto mechanism credit, etc. taken into account in the result, the adjusted CO₂ emission in FY 2011 was 124.2 million tons (13% increase compared to the previous year) and the adjusted CO₂ emission factor was 0.463kg-CO₂/kWh (24% increase compared to the previous year).

Although electricity sales decreased in FY 2011, both the CO₂ emission and the adjusted CO₂ emission factor increased due to an increase in the power generated at thermal power stations as a result of the long-term shutdown of nuclear power stations.

The CO₂ emission factor will be announced as the emission factor per electric utility after the government review.
