5-Year Environmental Action Plan

Approach

The NGK Group promotes environmental management integrated with its business activities, working toward the realization of the NGK Group Environmental Vision. We are currently strengthening our response to environmental challenges under the Sixth 5-Year Environmental Action Plan.

Sixth 5-Year Environmental Action Plan (FY2026–FY2030)

We developed the Sixth 5-Year Environmental Action Plan by building on the outcomes and lessons of previous plans, with a strong focus on alignment with our materiality, long-term management plan, NGK Group Environmental Vision, and NGK Group Environmental Policy.
In addition to carbon neutrality, where progress is most advanced, the plan strengthens our efforts toward a circular society and coexistence with nature. For a circular society, we promote the circular economy. For coexistence with nature, we address risks and opportunities based on the recommendations of the Taskforce on Nature-related Financial Disclosures (TNFD).
As a comprehensive response to our materiality, we have also incorporated environmental pollution prevention, including pollution prevention, as a key theme of the Sixth Plan.
Looking beyond 2030, in addition to advancing the circular economy, we are initiating the quantification and disclosure of environmental contributions from our products and services.
We will also respond appropriately to sustainability disclosure requirements, including SSBJ (Sustainability Standards Board of Japan) standards and CSRD (Corporate Sustainability Reporting Directive), and work to deepen stakeholders' understanding of NGK Group's initiatives.
The Sixth Plan sets clear, quantitative management targets. We manage performance at appropriate levels from the perspectives of societal expectations and enhancement of corporate value. By FY2030, we will publish target values for high-priority items, sending a clear commitment to both internal and external audiences.

Key Highlights of the Sixth 5-Year Environmental Action Plan

  • With an eye on FY2030 and beyond, we are strengthening efforts on the circular economy, addressing nature-related issues, and developing and introducing environmental contribution indicators for our products and services.
  • We are also strengthening initiatives across the value chain through reducing Scope 3 emissions, promoting resource circulation, and addressing coexistence with nature.

Structure of the Sixth 5-Year Environmental Action Plan

  • The plan consists of initiatives aligned with the NGK Group Environmental Vision and initiatives targeting the protection of the global environment as a whole.

Initiatives by Category

Toward Carbon Neutrality (GHG Emissions Reduction)

We advance Scope 3 emissions reduction through innovation, renewable energy use, and value chain initiatives, with a focus on the period beyond 2030.

This table summarizes our carbon neutrality initiatives and KPIs. We reduce Scope 1 and 2 emissions through energy conservation and the use of our own products. We also advance Scope 3 emissions reduction through innovation, renewable energy use, and value chain initiatives, with a long-term view extending beyond 2030. PDF file opens in a new window

Toward a Circular Society (Circular Economy)

Building on our longstanding efforts to reduce facility waste, we are expanding our focus to the value chain and taking action to address the circular economy, a growing global trend.

This table summarizes our circular society initiatives and KPIs. With circular economy promotion as the overarching theme, it presents specific initiatives and KPIs for the efficient use of raw materials, waste reduction, and product reuse and extended service life.

Toward Coexistence with Nature (Nature Positive)

NGK Group addresses the risks and opportunities in its relationship with nature, as identified through TNFD disclosures. To reduce our environmental impact on nature, we are strengthening efforts in water resource conservation, alongside our existing pollution prevention measures.

This table summarizes our coexistence with nature initiatives and KPIs. With nature positive promotion and pollution prevention as the overarching themes, it presents specific initiatives and KPIs for reducing the environmental impact of raw materials, water resources, air emissions, and our own products.

General Environmental Initiatives (Environmental Contribution of Products, External Assessment, Disclosure, Collaboration, Training)

Looking ahead to FY2030 and beyond, we will begin quantifying the environmental contribution of our products and services. We will also advance our response to sustainability disclosure frameworks and standards, including the EU's CSRD and Japan's SSBJ standards.

Looking ahead to fiscal year 2030 and beyond, we will begin quantifying the environmental contribution of our products and services. We will also advance our response to sustainability disclosure frameworks and standards, including the EU's CSRD and Japan's SSBJ standards.

Results and Review of Fifth 5-Year Environmental Action Plan

Under the fifth 5-Year Environmental Action Plan, NGK Group advanced company-wide initiatives across three priority themes: carbon neutrality, circular society, and coexistence with nature. We achieved all targets set for FY2025.
In carbon neutrality, we reduced CO2emissions and expanded renewable energy adoption. We also commenced Scope 3 emissions disclosure and initiated efforts toward SBT certification. In the circular society area, we made meaningful progress in waste reduction. At the same time, we recognize that transitioning to a circular economy grounded in resource recycling remains a key challenge ahead. In coexistence with nature, we began addressing TNFD requirements, working to identify nature-related risks and opportunities and strengthen our disclosures.
Building on these results and remaining challenges, the sixth 5-Year Environmental Action Plan will advance our environmental initiatives and further embed them in our business operations, contributing to the realization of a sustainable society.
