Methodology for calculating CO₂ emissions
· The factors of fuels are based on the Guidelines for Calculating Greenhouse Gas Emissions (Ver. 2.2) by the Ministry of the Environment, Japan
· The factors used for purchased electricity are the average of all types of power at the using end, reported by the Federation of Electric Power Companies of Japan.
· The CO₂ emissions factors (kg-CO₂ /kWh) for individual fiscal years are set at 0.417 for fiscal 1991, 0.425 for fiscal 2006 and 2007 and 0.410 for fiscal 2008 and onwards.
· In CO₂ emissions per basic unit of actual production^*, we reduced by 34% in fiscal 2009 compared to fiscal 1991 level when using 0.453 kg-CO₂ /kWh as the newest CO₂ emission factor against a 35% reduction target in fiscal 2011 by four electrical and electronics-related associations in Japan. When using 0.417 kg-CO₂ /kWh for a CO₂ emission factor, which is the same as a base year, a reduction rate in fiscal 2009 was 38%.
* CO₂ emission per basic unit = CO₂ emissions/(consolidated sales/Bank of Japan’s corporate goods price index [electrical machinery and equipment])
