Editorial Policy of Sustainability Website

Editorial Policy

NGK has created a dedicated sustainability section on its corporate website in order to deliver information about the NGK Group’s environmental, social and governance (ESG) initiatives for a sustainable society to a broad range of stakeholders in a timely manner.
We have archived our initiatives as of the end of August 2023 under the title of the NGK Group Sustainability Website Data 2023 (PDF). Plus, we have collected data on each initiative over time in our ESG Data Collection (Environmental) (Social) (Governance).

We also publish the NGK Report which conveys financial and non-financial information together with business strategies in a concise and clear manner to foster greater understanding of the NGK Group’s corporate value and vision.
