*1: Target reviewed owing to change in production plan. *2: CGS operating rate reduced owing to the effect of increased price of city gas. *3: PFC recovery measures suspended. *4: Reuse rate lower for products produced overseas in comparison with Japan.
Mid-term environmental strategies
The Elpida Memory Group is working to establish Elpida Memory as an environmental brand by creating eco-products that benefit the environment, ensuring that its factories are ecologically friendly, and raising environmental awareness, based on the following mid-term strategies:
benefiting the environment by creating eco-products with higher device integration and functionality, and less energy consumption;
increasing numbers of chip per unit wafer by shrinking the design rule, thus boosting productivity (manufacturing energy consumed per product);
increasing the efficiency of manufacturing processes and reducing the energy and resources used per unit wafer or unit production, to attain the goal of ecofactories that exceed industry standards;
reducing greenhouse gases by introducing new materials and manufacturing technologies;
reducing waste through the adoption of new wasteprocessing technologies;
implementing measures to spread environmental awareness among employees, their families, and local communities; and
establishing the image of Elpida Memory as an environmental brand.
Promotion of plan for complete elimination in FY2008
Completely eliminated by FY2008
*1: The conversion factor for CO2 emissions of purchased power supply is based on the conversion factor used by power suppliers in a reference year. *2: If it is assumed that wafer input to the 300-mm line will be 100,000 wafers/month in 2010 and the 200-mm line will be decommissioned, the amount produced will change accordingly.
* Increasing the memory capacity per unit area of wafer and reducing CO2 emissions per wafer mean that CO2 emissions in total bit units will decrease by half by 2010 compared with 2006.
