Sustainability Management
Basic Approach
Based on the NGK Group Philosophy of Enriching Human Life by Adding New Value to Society, we aim to provide new value through our unique ceramic technologies to contribute to the realization of a sustainable society and earn the trust of society by meeting its expectations toward us.
We have made this our basic philosophy with respect to the sustainability of the NGK Group. And in order to achieve the NGK Group Philosophy, we will contribute to bring about a carbon neutrality and digital society while keeping ESG (Environmental, Social, Governance) and the Sustainable Development Goals (SDGs) in mind. In this way, we aim to improve our sustainable value creation.

Governance
The NGK Group positions ESG at the center of our corporate management. Amidst ongoing overseas business expansion, we seek to ensure greater managerial transparency and autonomy in an environment which cultivates within every member of the NGK Group a sense of fairness accompanied by decision-making and action in accordance with international norms.
The risks and opportunities related to our Group’s sustainability issues that include ESG elements, are collected and confirmed by the Sustainability Management Committee. The details of Sustainability Management Committee activities are then reported to the Board of Directors at least once a year, and necessary items are discussed and reported at meetings of the Board of Directors and the Executive Committee before being implemented as policies. In addition, the Risk Management Committee monitors the formulation of policies, development of frameworks, and status of execution relating to risk management. Various committees, etc. also perform risk management for individual risk items. The President serves as the chair of the Sustainability Management Committee and Risk Management Committee, and the executive officers and department managers in-charge of head office divisions and business divisions serve as its members.

Risk Management
The risks and opportunities related to the NGK Group’s sustainability issues are identified and handled as important material items by the Board of Directors and the Executive Committee.
When identifying materiality, we evaluated various environmental and social issues that were candidates for materiality along the two axes of “impact on our business” and “demands and expectations of stakeholders/impact on people and the environment” then used this to create a materiality map. Based on this, the Sustainability Management Committee extracted materiality candidates, then the Board of Directors and the Executive Committee considered the risks, opportunities, and primary initiatives for each, and determined them to be material items.
These items are handled by each of the related committees, then brought together by the Sustainability Management Committee. Meanwhile the risks and opportunities are monitored, managed (governance), identified, and evaluated (risk management) through reports, etc. to the Board of Directors and the Executive Committee.
Strategies, Indicators, and Objectives
We have set KPIs for all of our material items, and are pursuing relevant initiatives.
Core Themes of Sustainability Activities
We identify materiality based on the NGK Group Basic Sustainability Policy. And we work to enhance the effectiveness of governance to serve as the foundation of value creation as we promote environmental and societal initiatives.
