Resource Conservation
We are reducing paper consumption as part of our strategy to conserve resources.
TEL is also taking other measures for effective use of resources, such as water conservation, avoiding
vehicle engine idling, and purchasing recycled products.

Efforts to Reduce Paper Usage
All companies in TEL are working to reduce of paper consumption. For example, all employees are encouraged to use both sides of172097

paper and to reduce the paper size when making copies. In addition,(All sites in Japan and a portion of sites overseas)

efforts are being made to share information without using paper, forexample, by using electronic means for intra-office memos and notices. As a result of these and other efforts, the entire TEL used about
12 million fewer sheets of copy paper in FY 2003 than in the previous year, a reduction of about 11%.
We will continue to use recycled paper in every sites (with theexception of a few special applications), and to review office procedures thereby to minimize the use of paper records and forms.
We are also trying to help protect forests by using paper cups
made of kenaf in place of conventional paper made from wood fiber,
and are encouraging employees to limit the use of paper cups.

Installation of Water-Saving Systems(Air-Cooled Vacuum Pump)
To reduce water usage, the Saga plant has converted from awater-cooled vacuum pump used in manufacturing to an aircooled type. This is because calculations and a study by the Resource Conservation Committee showed that the conventional
pump was consuming a large amount of municipal water. By
converting, the plant
was able to reduce water usage by about
18,000m3 per year,
which was also quite
good in terms of costbenefit analysis.
