NGK ISSUES ENVIRONMENTAL REPORT 2002

NGK INSULATORS, LTD. has issued its "Environmental Report 2002" an annual statement which covers NGK's commitment to environmental conservation for the fiscal year 2002.
This year's environmental report is the fourth edition since the first issue in FY1998. The Report is an upgraded version of the FY2001 report which followed a new format based on the Environmental Reporting Guidelines as per the Ministry of Environment. It thoroughly covers various environmental conservation activities, including the Environmental Action Plan in effect until 2006, broad schedules, and specific achievements. Furthermore, this report was issued three months in advance. NGK's "Environmental Report" will be issued annually and can be found on our Internet homepage at: http://www.ngk.co.jp/.
In this new age, in which the very structure of society is changing, and regulation systems related to the environment are being augmented to respond to the needs of a society that values environmental conservation, NGK has established a "Core Policy on the Environment" aimed at contributing to the solution of environmental challenges based on the "Triple-E" business fields of Ecology, Electronics and Energy.
In addition, one of the policies of our new three-year management plan, starting from fiscal 2002, is "Green Management", which aims at contributing to a variety of environmental action assignments. Green Management is comprised of four main activities: 1) preventing global warming, 2) reducing emissions, 3) developing products that benefit the environment, and 4) implementing Green Logistics. Furthermore, to respond swiftly to the needs of a sustainable society, each fiscal year NGK establishes the Environmental Action Plan. And NGK will further enhance its environmental activities through its business operations groupwide. The Annual Report 2002 stipulates NGK's various environmental conservation activities focusing mainly on the contents as follows:

Environmental Accounting

  • In FY 2000, NGK introduced environmental accounting as a tool for managing and ascertaining the state of its environmental conservation activities.
  • The environmental cost in FY 2002 rose approximately ¥890 million from the previous fiscal year to ¥2.61 billion owing to the reinforcement of facilities and the development of processes to decrease the burden on the environment. The direct economic effect from environmental conservation measures rose approximately ¥100 million from the previous fiscal year to ¥280 million, mainly as a result of the increased sales of reusable substances, and the conservation of energy and resources.

ISO 14001 Certification

  • Continuing groupwide efforts (including overseas) are being made to acquire ISO 14001 certification. In March 1998, NGK's three main domestic production bases simultaneously received ISO 14001 certification, and 10 domestic Group companies as well as 4 overseas Group companies also received certification for their plants. By fiscal 2002, 53% of our consolidated business sites had been ISO 14001 certified.
  • By FY2007, 100% of our consolidated business sites will have ISO 14001 and other certification.

Energy Conservation (Reduction of CO2 Emissions)

  • Efforts to prevent global warming are focused on such production facilities as large size kilns, and include developing or improving combustion technologies to conserve energy as well as shifting to the use of environmentally friendly fuels that reduce the volume of CO2 emissions.
  • The total CO2 emission volume in FY2002 was 162,000 tons, showing only a slight (0.3%) increase since the previous year. The basic unit (total amount/sales) was 79.2 tons of CO2/¥100 million, an increase of 9.2 tons of CO2/¥100 million mainly due to a drop in net sales. The basic unit (total amount/production) (index) was 92.4%, showing a decrease of 3.2% due to increased energy conservation.
  • In FY2002, NGK started to calculate its greenhouse gas emissions. The emission amount decreased 11% to 166,000 tons from the previous year largely due to 60% reduction of SF6 insulating gas, which has a particularly strong greenhouse effect.
  • CO2 emissions reductions target is to decrease the number of basic unit (total amount/sales) to FY1991 levels (70 tons of CO2/¥100 million) by FY2006.

Reduction of Industrial Waste

  • In addition to reducing various types of industrial waste generated during its production processes, efforts are being stepped up to effectively reuse and render into new resources those waste products in order to realize zero emissions.
  • The total volume of industrial waste produced in fiscal 2002 was 18,424 tons, an increase of 26%, and the total volume of waste for final disposal was 7,754 tons, an increase of 34% from the previous year, mainly due to temporary increase in waste materials accompanying the renewal of the tunnel kiln. The total volume of material recycled increased 20% to 10,670 tons from the previous year.
  • NGK is targeting at reducing waste for outside disposal by 50% (2,700 tons) compared to FY 2001 level by FY2004 and achieving zero emissions in fiscal 2006.

Management of Chemical Substances

  • Full-fledged operation of the Chemical Substances Management System began in October 2001 and, currently, more than 8,000 chemicals are registered in the system. NGK's chemicals are carefully stored in its approximately 1,200 storage boxes.
  • NGK handled 337 tons of 62 PRTR-listed substances in FY2002, as well, 10 substances were reported to the government. Atmospheric emissions of PRTR-listed substances in FY2002 totaled 31 tons, and the amount transferred was approximately 34 tons.
  • NGK plans to reduce over 80% of atmospheric solvent emissions of PRTR-substances to FY2001 levels until FY 2006.

Green Purchasing

  • Starting in the fall of 2000, NGK began a full-fledged implementation of a policy to give preference to the purchase of consumables, such as office supplies, that qualify as Green Products. In March 2002, a new purchasing system, Benrinet, was introduced, and 500 new Green Products were added to the system, bringing the total to 850 products.
  • In September 2001, NGK concluded a contract with Japan Natural Energy Co., Ltd. for Certification of the Green Power system, and began commission of 2 GWh of wind power per year from January 2002, corresponding to reduction of 806 tons of CO2 emission.
