Carbon Neutrality Strategic Roadmap and 5-Year Environmental Action Plan

To achieve the NGK Group Environmental Vision, we formulated a Carbon Neutrality Strategic Roadmap built on four strategic pillars. The Group has set a target of achieving net zero CO₂ emissions across the entire Group by 2050. As milestone targets on the path to this goal, we aim to reduce CO₂ emissions to 500,000 tons in FY2025 (a 32% reduction compared with FY2013) and to 370,000 tons in FY2030 (a 50% reduction compared with FY2013).CO₂ emissions in FY2025 are currently projected to be approximately 400,000 tons, and we expect to achieve the FY2025 target. Looking ahead, we will consider accelerating the achievement of net zero by promoting the development of technologies related to hydrogen and CCU/CCS (carbon capture, utilization, and storage).

Carbon Neutrality Strategic Roadmap (Scope 1 and Scope 2)

In FY2021, we established the fifth 5-Year Environmental Action Plan, which encompasses our environmental action targets through FY2025.
This is the first five-year plan aimed at realizing the NGK Group Environmental Vision announced in April 2021, which targets net zero CO₂ emissions by 2050. We aim to achieve our Environmental Vision by focusing on its key themes of carbon neutrality, a recycling-oriented society, and harmony with nature.

Reference Year, Target Year, Control Scope

• Reference Year: FY2013 (for some, FY2019)
• Target Year: FY2025
• Control Scope: Consolidated (for some, Japan)

Below are the results to date of this 5-Year Action Plan, the targets and results for FY2024, and the targets for the final year of this plan, in FY2025.
Regarding the target for consolidated CO₂ emissions in FY2025, we have revised the target from 550,000 tons, which was set in early 2021, to 500,000 tons. This revision reflects the steady progress made in energy saving initiatives and the expansion of renewable energy adoption.

We achieved all of our targets for FY2024.
We were able to achieve our target with our carbon neutrality efforts. We emitted 540,000 metric tons of CO₂ in contrast to our target of 600,000 metric tons by promoting energy conservation activities, expanding the use of renewable energy and taking other measures. In addition, the rate of the power we used derived from renewable energy was 26%. Thus, we also achieved this target.
We achieved our quantitative targets for the reduction of waste and the management of water withdrawal in our efforts toward a recycling-oriented society.
In terms of harmony with nature, we promoted an expansion in the content of our disclosures based on the Taskforce on Nature-related Financial Disclosures (TNFD).
We contributed to local communities and raised environmental awareness by holding seminars with the Environmental Partnership Organizing Club (EPOC) and using in-house presentation meetings to promote environmental communication.
