Clean Factories - Factory Energy Conservation

• Energy-conservation rate^* targets and results (fiscal 2007)

Greenhouse gases (GHGs) typically emitted from our operations comprise CO₂, together with Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs) and Sulfur Hexafluoride (SF6). Of these gases, CO₂ emitted through energy consumption accounts for 92% of the total emissions. We have set a target for fiscal 2011 to reduce CO₂ emissions per basic unit^*1 by 10% from fiscal 2001 levels, on a global basis. Additionally in Japan, we are simultaneously seeking to achieve the target^*2 set for fiscal 2011 by the four electrical and electronics-related associations:^*3 to reduce CO₂ emissions per unit of actual production by 28% from 1991 levels. In fiscal 2007, we achieved a 24% reduction (from fiscal 2001 level) on a global basis and a 35% reduction (from 1991 levels) in Japan, accomplishing both our targets. Efforts to reduce CO₂ emissions from factories are also being made based on the Three-Year Energy Conservation Plans formulated by each business site, which are revised annually. We have introduced our own energy-conservation rate as an indicator of the effectiveness of our corporate efforts.
   We intend to step up our energy conservation activities, particularly in the business segments and regions that exhibit an increase of CO₂ emissions.
