|
Fighting Global Warming |
|
| Strategies |
| · |
Reduce emissions of carbon dioxide (CO2) and other gases that contribute to global warming |
| · |
Reduce energy consumption |
| Goals |
| · |
Reduce the consumption of electricity, water and gas from production equipment and on-site facilities, and reduce CO2 emissions by at least 6% by 2012 compared with the baseline year of 1990 (in accordance with the Kyoto Protocol) |
| · |
Reduce energy consumption (CO2 equivalent) by unit of production output, by an average of at least 1% per year for the medium- and long-term future, and by at least 25% by 2012 compared with the baseline year of 1990 (in accordance with Act on the Rational Use of Energy and targets established by the Japan Electrical Manufacturers' Association) |
| Current Progress |
| · |
Ongoing participation in the Japanese government's Challenge 25 campaign
Adopted policies to promote casual dress codes in summer months at head office, branch offices and subsidiaries (2004)
Adopted policies to shut off external lighting for company signage at plants (2006)
|
| · |
Implemented policies to shut off computers and lighting during lunch hours (2004) |
| · |
Ongoing conversion of HVAC fan motors and exhaust fan motors at plants to energy-efficient inverter units |
| · |
Upgraded light fixtures (fluorescent and mercury vapor) at plants to energy-efficient fixtures |
| · |
Reviewed the company's contract electricity and reduced the peak power demand, based on power savings gained from implementing the above day-to-day energy conservation measures (November 2006) |
| · |
Planning to examine methods for achieving partial self-sufficiency of power through deployment of power generating equipment based on clean energy such as solar and wind power |

|
Reducing Waste |
|
| Strategies |
| · |
Engage in detoxification of PCB-contaminated waste |
| · |
Reduce the volume of industrial waste for landfill disposal |
| Goals |
| · |
Finish the detoxification of PCB-contaminated waste by 2016 (in accordance with Japan's Law Concerning Special Measures Against PCB Waste)
|
| · |
Reduce the volume of industrial waste for landfill disposal to 89% or lower compared with levels in the baseline year of 1998 (in accordance with targets established by the Japan Electrical Manufacturers' Association) |
| Current Progress |
| · |
Launched initiatives to improve paper recycling (2003) |
| · |
Constructed holding area for industrial waste and implemented stricter rules for waste processing (2004) |
| · |
Implemented stricter sorting of scrap metal (2005) |
| · |
Deployed "tear and crush" shredders that are better suited for paper recycling (2006) |
| · |
Initiatives for shredding and recycling of confidential documents were featured on an NHK television new program (March 2007) |
| · |
Filed application for dexotification of PCB-contaminated waste (2006) |

| Fig. 2 Total CO2 Emissions and CO2 Emissions by Unit of Production Output |
|
Achieved a 53% reduction of total CO2 emissions in 2006 compared with 1990 levels. The reduction is partly due to the consolidation of manufacturing facilities, but also the result of active investment in energy conservation technologies as part of the company's recent efforts to reduce CO2 emissions.
CO2 emissions by unit of production output in 2006 are down by 34% compared with 1990 levels, due to the reduction of total CO2 emissions and improvements in production efficiency. |
|
|
| Fig. 3 Landfill Disposal of Industrial Waste |
|
The volume of industrial waste destined for landfill disposal is down by more than 10% in FY2006 compared with levels in 1998. |
|
|
| Fig. 4 Recycling Rate of General Waste |
|
Output of general waste was more than 1,200 tons in 1996, but has lately hovered at around the 600 ton level. The recycling rate has steadily improved to exceed 70% as a result of implementing initiatives for paper recycling, from around 30% previously. |
