ESG Management

NGK Group Basic Sustainability Policy

Since our founding, the NGK Group has worked to solve social issues through our unique ceramic technologies. Based on the NGK Group Philosophy of Enriching Human Life by Adding New Value to Society, we aim to continue contributing to the realization of a sustainable society and to earn the trust of society by meeting its expectations toward us. We have incorporated this thinking into the NGK Group Basic Sustainability Policy in April 2023.

ESG Action System

ESG (Environmental, Social, Governance) is central to the management of the NGK Group. Amidst ongoing overseas business expansion, we seek to ensure greater managerial transparency and autonomy within 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.
In 2019, the ESG Committee was established as a body for information sharing, opinion exchange and policy discussion among senior management. In 2021, the ESG Management Department was established in order to handle lateral implementation of ESG-related activities across the NGK Group and to strengthen information dissemination about the activities. Furthermore, in April 2022, the ESG Committee was reorganized as the ESG Management Committee, which is chaired by the President, as a body reporting to the Board of Directors for strengthening initiatives on sustainability issues that incorporate elements of ESG and the SDGs.
In 2025, the ESG Management Committee was renamed the Sustainability Management Committee.

NGK Group Signs UN Global Compact

The NGK Group is a signatory to the United Nations Global Compact, which advocates for independent action on the part of companies, endorsed by the United Nations. We believe that addressing a broad range of social problems through our business activities, while measuring progress against indicators such as the Sustainable Development Goals (SDGs), is an important corporate social responsibility.

Task Force on Climate-Related Financial Disclosures (TCFD)

In February 2020, the NGK Group announced our support for recommendations issued by the Task Force on Climate-Related Financial Disclosures (TCFD) created by the Financial Stability Board (FSB). Since then, we have evaluated how to apply the TCFD framework towards resolving issues facing NGK Group operations, such as the risks and opportunities posed by climate change, and towards necessary information disclosure.
Below, we disclose information related to scenario-specific analyses conducted based on the four themes outlined in the TCFD recommendations: governance, strategy, risk management, and metrics and targets.
We will continue to expand analysis work and enhance information disclosure as part of our commitment to communicating with our stakeholders. We will accurately identify climate change-related influences on Group operations and implement response measures to promote sustainable growth for our business.

Information Disclosure Based on TCFD Recommendations

Taskforce on Nature-related Financial Disclosures (TNFD)

In January 2024, the NGK Group endorsed the efforts of the Taskforce on Nature-related Financial Disclosures (TNFD), an international initiative that strives to develop and provide a framework for disclosing nature-related financial information. We also registered as a TNFD Early Adopter. Going forward, we will promote disclosures aligned with the recommendations of the TNFD, and accelerate our efforts to protect and restore biodiversity and nature.

Information Disclosure Based on TNFD Recommendations

SBTi (Science Based Targets initiative)

The NGK Group has obtained certification from the international accrediting agency SBTi (Science Based Targets initiative)*1 under its Corporate Net-Zero Standard*2 for our greenhouse gas reduction targets. We are working towards a more than 90% reduction in emissions (Scope 3) by 2050 for our entire value chain compared to the base year of FY2022. As a step towards achieving this goal, we have set a target of 25% reduction in Scope 3 emissions by 2030 compared to the base year. This has allowed our goal to be certified as a Net-zero target by SBTi.

SBTi (Science Based Targets initiative)

1 SBTi
An international environmental initiative that encourages companies to set greenhouse gas emission reduction targets in line with what the latest climate science deems necessary to meet the goals of the Paris Agreement – limiting the rise in average global temperatures to 1.5°C above pre-industrial levels. It was jointly established in 2015 by four organizations: the CDP, the United Nations Global Compact, World Resources Institute (WRI) and the World Wide Fund for Nature (WWF).

2 Corporate Net-Zero Standard
A standard for achieving the goal set by the Paris Agreement of limiting the rise in average global temperatures to 1.5°C above pre-industrial levels. SBTi recognizes that in order to keep the rise in global average temperatures to 1.5°C, it is necessary to reduce emissions of greenhouse gases by at least 90% throughout the entire value chain by the year 2050. The initiative believes that Net zero can be achieved by removing the remaining 10% of greenhouse gases from the atmosphere using techniques such as carbon removal.

RE100

RE100 (100% Renewable Electricity) is a global initiative made up of companies that aim to use renewable energy to power all of their operations. We joined the initiative in October 2022. The NGK Group identified carbon neutrality as one of the social issues to be addressed in its mid- to long-term vision NGK Group Vision: Road to 2050. In the NGK Group Environmental Vision formulated at the same time, the Group set the target of net zero CO₂ emissions by 2050 and has been working on expanding its use of renewable energy as a strategy to achieve this target.
