Release: December 18, 2001


NGK INSULATORS, LTD. has issued its "Environmental Report 2001" which covers NGK's commitment to environmental conservation for fiscal year 2000.

In order to nurture the health of a viable environment for the next generation, NGK pursues its "Triple E" areas of Ecology, Electronics and Energy. The key concept of the Company's Core Policy of the Environment is to contribute to the solutions of environmental issues through our work in these three areas. NGK not only strives to reduce the environmental impact of all business activities, but also to develop products and technologies that contribute to environmental conservation.
The Report specifically introduces NGK's various environmental protection activities focusing mainly on energy conservation and waste reduction. This year's report follows a new format, based on the Environmental Reporting Guidelines of the Ministry of Environment, and includes consolidated data of manufacturing subsidiaries located in Japan.

1. Based on the Environmental Reporting Guidelines

The Environmental Reporting Guidelines issued by the Ministry of Environment in February 2001 position an environmental report as an environmental communication tool, and include necessary contents to fulfill social accountability. The entire format of the "Environmental Report 2001" has been based on these Guidelines. The following items have been modified or added.

1) NGK and the Environment

The complete picture of the main input/output in production is clearly specified in addition to NGK's business activities and involvement regarding environmental impact. The main input/output in production covers input amount of energy, material, chemical substances etc. and output amount of products, CO2, industrial waste etc.

2) NGK's Environmental Action Plan

NGK has established the Environmental Action Plan aimed at strengthening and expanding its environmental activities currently underway. To achieve this goal, the Company enhances its efforts in such areas as reduction of industrial waste and chemical substances, and includes manufacturing subsidiaries in these efforts. NGK has set goals of reducing CO2 emissions on a per net sales unit basis to fiscal 1990 levels by fiscal 2005 and reducing 50% of amount of waste disposal by fiscal 2003 to achieve no-waste in fiscal 2005.

3) Environmental Accounting (Environmental Conservation Effects, Economic Effects)

In fiscal 1999, NGK introduced environmental accounting as one tool for comprehending and managing its environmental protection activities. This year, we have calculated Environmental Conservation Effects and Economic Effects in addition to Environmental Costs. The environmental cost in fiscal 2000 was 1.72 billion yen on a non-consolidated basis. The direct economic effect amounted to 160 million yen due to sales of useful substances.

4) Management of Chemical Substances (Amount of substances handled, emitted and transferred)

PRTR-listed chemical substances that are handled, emitted and transferred are calculated based on the chemical substances management system established in 1999. NGK handled 236 tons of 67 chemical substances, of which 12 substances required reporting in fiscal 2000. Atmospheric emissions and other types from these substances totaled 25 tons, and around 10 tons were transferred to outside the site.

2. Added Consolidated Data

Since disclosure on a consolidated basis has become the mainstream approach in recent years, NGK added consolidated data of 14 domestic manufacturing subsidiaries. Objective coverage in this area will be expanded in the future.

This year's environmental report is the third edition since the first issue of FY 1997 report. Our "Environmental Report " will be issued annually and put on our Internet homepage at:
