Basic Philosophy

Major climate change could cause the risk of hindering the establishment of a sustainable society. As a part of our activities to aid in mitigating climate change from medium- and long-term perspectives, we set targets for CO2 emission basic unit in fiscal 2020 under Global Eco Vision 2020. Aiming at achievement of the targets, we have been proceeding with fractionalization of energy management, and reduction in energy consumed by air conditioning system while focusing on building ventilation amount.

Achieving Target CO2 emission basic unit in fiscal 2016

The CO2 emission basic unit in fiscal 2016 was 1.25 tons/million yen, meeting our fiscal 2016 target of 1.28 tons/million yen (decrease by 1% as compared with fiscal 2015). The CO2 emission basic unit has been improved by 16% for 5 years since fiscal 2012 owing to energy saving effect resulting from updating of facilities (energy-saving type) and revising our manufacturing conditions.

Energy Conservation during Transportation

As a Specified Consigner designated under the Act on the Rational Use of Energy, we endeavor to reduce CO2 emissions during transportation, proceeding with reduction in shipping distance by reorganizing/integrating plants, and reconsidering the waste-disposal service vendor.
In fiscal 2016, our energy usage basic unit was 1.05 kL/100 million yen, improved by 1.3% as compared with the previous fiscal year.

Energy Conservation in Office

We implement daily energy-saving measures in our workplaces, including turning off lights and computers during breaks and keeping office air conditioning at moderate levels, 28ºC in summer and 20ºC in winter, to which we adjust by dressing lightly or adding layers of clothing.
We are also creating green curtains, installing arched sunshades and thermally insulating the outdoor units of air conditioners to reduce power consumption for air conditioning in the summer.
In fiscal 2016, too, we worked to consolidate PC servers, upgrade air conditioners, and convert fluorescent lighting to LED lighting.

Use of Natural Energy

We promote the use of natural energy.
We installed three solar power generation units and one solar water heater at our Headquarters Factory. The Komaki Plant has a solar power generator unit that can generate a maximum of 107 kW of electricity. In overseas, the solar power generation units have been introduced into Woojin Industry Co., Ltd., and NGK Spark Plugs (India) PVT. LTD. In fiscal 2016, we generated a total of 350 MWh sourced from natural energy in both domestic and overseas companies, which is equivalent to reduction of 200 tons of CO2.
