Clean Factories - Factory Energy Conservation

• CO₂ emissions per basic unit (global)
• CO₂ emissions per unit of actual production (Japan)
• CO₂ emissions (by region)
• CO₂ emissions breakdown by fuel (Japan)

• * The GHG protocol's CO₂ emissions factors for each country are used for electricity purchased outside Japan.
• * The factors related to fuels are based on the Guidelines for Calculating Greenhouse Gas Emissions from Businesses (Draft 1.6) by the Ministry of the Environment, Japan.

• * The factors used for purchased electricity are the average of all types of power at the point of use, reported by the Federation of Electric Power Companies of Japan.
• * CO₂ emissions factors for individual fiscal years are: 0.410 kg CO₂/ kWh (fiscal 1991), 0.407 kg CO₂/kWh (fiscal 2003), 0.436 kg CO₂/kWh (fiscal 2004), 0.421 kg CO₂/kWh (fiscal 2005), and 0.425 kg CO₂/kWh (fiscal 2006). The value for fiscal 2006 is used for estimating the level of fiscal 2007.
• * The calculation method for CO₂ emissions per unit of actual production (Japan) was changed. The effect of the fiscal 2002's revision of in-house system was not reflected in fiscal 1991. Therefore, figures for past fiscal years were also changed. In comparison with the previous calculation method, basic unit indexes have been lowered by about 16% in each year.
