Clean Factories - Factory Energy Conservation

• CO₂ emissions reduction achieved by introduction of co-generation systems (CGS) (Japan)
• Power generation and ratio of Co-generation electricity to total electrisity (Japan)

• *1 Average CO₂ emission factor for all types of power, including nuclear, thermal, hydro, and renewable.
• *2 CO₂ emission factor correction value (for CGS power) = CO₂ emission factor of thermal power - average CO₂ emission factor for all types of power (on the assumption that in-house CGS power replaces thermal power).
• * The CO₂ emissions factor for each fiscal year was 0.410 kg CO₂/kWh (FY1991), 0.407 kg CO₂/kWh (FY2003), 0.436 kg CO₂/kWh (FY2004), 0.421 kg CO₂/kWh (FY2005), and 0.425 kg CO₂/kWh (FY2006). The CO₂ emissions factor for FY2007 is calculated with the value of FY2006.
