Environmental Communication

Print this page

Basic Philosophy

It is essential for the NGK SPARK PLUG's GROUP to realize close coordination with local communities and become highly reliable for continuous business operations. For achievement of the goal, sharing information on the Group's environmental activities is regarded as the best approach. We have been endeavoring to disclose information and improve communication in an accurate and easy-to-understand way.

Hosting plant tours

We accept plant tours for the purpose of observing our environmental efforts and facilities. A deeper understanding of our Group's activities and better communication are achieved by seeing our facilities firsthand and engaging in question and answer sessions. In fiscal 2016, we hosted 56 tours and welcomed 1,198 visitors at our plants.

Environmental Meeting

We host environmental meetings with local residents as a venue for communication. At these meetings, we explain our daily environmental activities as well as hear opinions and comments from participants on how we can further improve things. In fiscal 2016, we hosted 8 such meetings, with a total of 28 participants.

Local Clean-up Activities

We regularly hold clean-up activities near the office to preserve the local environment. We also continue to participate in beautifying activities hosted by local municipalities, etc. In fiscal 2016, a total of 832 people participated in such activities.

Conservation of Biodiversity

NGK SPARK PLUG’s GROUP defines preservation of biodiversity that has become increasingly important around the world as one of our environmental themes as essential as global warming control and recycling of resources.
In April 2013, we established the NGK SPARK PLUG Group Biodiversity Action Guidelines which indicate our policy and action plan regarding biodiversity.
Based on the guidelines, recognizing that activities such as the use of energy and resources have an effect on biodiversity, we will work in cooperation with business partners and external organizations to reduce the impacts of our entire business activities

System for Environmental Commendations

Based on our target to “Improve Environment Consciousness” set under the Global Eco Vision 2020, we have established an environmental commendation system for the NGK SPARK PLUG's GROUP to commend outstanding environmental initiatives.
The environmental commendation system was launched in 2014 aimed at environmental activities and initiatives in all divisions and departments of the company groups. The outstanding case will be commended by the President during meetings of the Central Environmental Committee.
In fiscal 2016, the third year of the system, commendations were given to 10 cases with respect to, for example, reduced CO2 emission during production by improving productivity and quality, reduced CO2 emission during logistics by enhancing efficiency of transportation between plants, reduced waste disposal by reconsidering operation process, product design that suppresses the use of rare metal, and development of environment-oriented products.


Comment by award-winning division

Contribution to Environment by Quality Improvement

We won the award on the theme of “Elimination of air cleaning step for removing adhered contaminant”.
As a result of our fundamental examinations on countermeasures against problem of chronic defective quality, we succeeded in elimination of cleaning air as well as quality improvement. Through our efforts, we have learned that quality improvement leads us to “Power reduction = CO2 emission reduction”. In spite of very small amount of air fed to each cylinder, the total air amount resulting from conversion into the annual figure over horizontal business network results in surprising effects. We will further take the initiative of “Quality improvement = Environmental activity” for further effects onward.
