Environmental Management

Print this page

Basic Philosophy

Our environmental management system, operating on the environmental policy shared by the entire Group, ensures systematic and effective environmental preservation activities. Under this system, all Group companies strive to achieve the Eco Vision.

Promotion system

Our group has a matrix-type structure including business departments and respective regions, promoting environmental activities while having individual roles clarified. Each department is expected to manage its own targets on items relevant to business activities, for example, “Global warming”, “Natural resources”, “Toxic, hazardous chemicals”, and “Key quality” under the Global Eco Vision 2020 for the practice along with business activities. Meanwhile, we take the initiatives to such activities as compliance of regulations, raising environmental awareness, and communication with local society mainly on the region basis in accordance with action plans. Various sub-committees are set up as the cross-functional team across the department for promoting activities.
The activities will be confirmed with respect to the progress toward the target, and task in Central Environmental Committee at which President, directors, department managers, environment control managers in the respective regions, and chairpersons of the sub-committees are present for continuous improvement.

The Establishment Status of our Environmental Management System

We received ISO 14001 integrated certification for NGK SPARK PLUG CO., LTD. and 9 group companies in Japan.
Other domestic and overseas group companies have already been certified for environmental management systems including ISO14001 certification, individually, resulting in 18 overseas group companies which have received the certification in the end of the fiscal 2018.

*See Sustainability Databook for the locations which acquired ISO14001.

Environmental Risk Management

Inherent in business activities are various risks including environmental incidents and pollution. NGK SPARK PLUG's GROUP identifies these risks and endeavors to reduce and/or prevent them.

PCB Control

PCB waste stored at our Nagoya Plant and Komaki Plant were disposed of in 2018. Only CS NAKATSUGAWA has PCB wastes and it is under strict control for proper disposal.

On-site Confirmation of Waste Material Treatment

We regularly visit our waste disposers to confirm that consigned waste materials are being processed in accordance with our agreement. In fiscal 2018, we visited 79 companies and confirmed that their waste was properly disposed of.

Handling of Asbestos

We have been taking appropriate measures to prevent health hazards from asbestos. All asbestos used in our facilities has been completely removed. Some asbestos is still present in buildings as insulators, and we will continue to adhere to stringent control measures and periodical confirmation.

Preventing Chemical Leaks

In order to prevent soil and water contamination caused by chemical leaks, we have been implementing countermeasures involving equipment that includes preventing leaks through the development of double layered storage tanks and the early detection of leaks by installing pipes above ground. Wastewater treatment facilities of the respective plants discharge the wastewater only confirmed to be harmless through monitor measurement under routine management.

Drills for Emergency Situations

We hold regular drills for emergency situations to prepare for unforeseen accidents, etc. Each department identifies potential environmental accidents to prevent associated adverse environmental impacts.
SparkTec WKS held drills for blocking drainage assuming that wastewater accidentally flows outside the premise.

Compliance Status

To ensure compliance with environmental laws and regulations as well as agreements with local municipalities, etc., we set stringent voluntary standards to prevent violations and complaints. In fiscal 2018, there were zero violations of laws or regulations in Japan, and three instances that demanded improvement concerning noise. Since we found problems on how and when we worked regarding noise complaints, we immediately carried out countermeasures, working to prevent recurrence.

Environmental Accounting

What is important in promoting environmental management is to gain a grasp of the costs and effectiveness of environmental preservation activities. We have been adopting environmental accounting since 1999, and in 2003 the accounting scope was expanded to include the Groups in Japan (integrated certification).
In fiscal 2018, our environmental conservation costs were 13,228 million yen for the Groups in Japan (integrated certification), a decrease of 13% over the previous fiscal year. The economic benefit associated with environmental conservation activities totaled 389 million yen.

Environmental Education

Environmental education is conducted to deepen employees’ understanding of environmental issues and raise their environmental awareness.
In addition to rank-specific education, we hold four courses on “Environmental basics”, “Environmental management system”, “Calculation methods for substances with an environmental burden”, and “Environmental laws and regulations (for facilities).
Starting in 2017, we went to the departments related to these four laws and regulations and provide on-site environmental law training focused on the necessary compliance.
In regard to the “Environmental Handbook” for employee education, we will enhance the content of the handbook to take in consideration the latest trends around the world.
