As part of its commitment to global environmental conservation, NHK Spring has identified the reduction of CO₂ emissions toward a decarbonized society and the achievement of zero industrial waste (non-recyclable materials) as materialities (important issues).

Since publishing the Environmental Voluntary Plan in 1993, the entire NHK Spring Group has been involved in global environmental conservation activities. To further clarify NHK Spring Group's future role in helping to realize a sustainable society, the President & CEO personally declared "NHK Spring Group's Environmental Challenges" in September 2021. In line with the Medium-Term Management Plan through FY2026, each Production Division is implementing measures to reduce CO₂ emissions and industrial waste (non-recyclable materials). Progress toward these goals is monitored through the Global Environmental Response Committee, which also discusses additional reduction measures. As of FY2024, initiatives are progressing as planned. In FY2025, we will advance preparations for the collection and aggregation of Scope 3 data.

Based on the NHK Spring Group's Environmental Challenges declaration, the Global Environmental Response Committee has formulated a long-term plan of environmental activities for each business and strengthened activities with a view to realizing a sustainable society in NHK Spring Group.
The Global Environmental Response Committee meets twice a year. The Committee sets interim goals related to the Environmental Challenges, and compiles scenarios and promotes activities for realizing them. It periodically reports on the progress of activities to the Management Committee so that they can be reflected in the management strategy.

At NHK Spring Group, we have been working to reduce CO₂ emissions in line with the NHK Spring Group’s Environmental Challenges, contributing to the realization of a decarbonized society. To identify the risks and opportunities that climate change presents to NHK Spring and their potential impacts, we conducted a scenario analysis with the aim of strengthening NHK Spring’s medium- to long-term strategy and examining the need for additional measures.

<TCFD Scenario Analysis>

■ In line with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), we identified and assessed a comprehensive range of climate-related risks and opportunities, selected those of highest relevance, and evaluated their significance through scenario analysis.

■ In the scenario analysis, we assumed two cases: one in which stringent climate countermeasures are taken, limiting the global temperature rise to below 2℃ compared with pre-industrial levels (the “Below 2℃ Scenario”), and another, for reference, in which temperatures rise by 4℃ compared with pre-industrial levels (the “4℃ Scenario”).

■ Under each scenario, we evaluated the potential impacts on NHK Spring’s business activities based on projected changes in the external and social environment for the years 2030 and 2050.

NHK Spring has built a risk management structure in which the President and Representative Member of the Board acts as the chief responsible officer and the President of the Corporate Planning and Control Division acts as the executive officer in charge. Under this framework, we manage risks including climate-related risks (both physical and transition risks).

In risk management, we work to prevent risks before they occur, minimize any damage, and establish countermeasures to prevent recurrence, while monitoring progress on their implementation.

At the same time, we recognize that establishing a governance process in which the Board of Directors is explicitly involved in risk management remains a challenge to be addressed, and we will work toward its realization going forward.

NHK Spring Group has set reduction targets for CO₂ emissions calculated from energy consumption and is engaged in global environmental conservation activities. Until FY2020, emissions were managed on a sales intensity basis, but since FY2021, with the aim of achieving carbon neutrality, they have been managed on a total CO₂ emissions basis.

As part of our proactive efforts to advance global environmental conservation, we have established CO₂ reduction targets under NHK Spring Group’s Environmental Challenges.

NHK Spring Group's Environmental Challenges
(CO₂ emission reduction targets for Scope 1 and Scope 2, covering NHK Spring and its domestic consolidated subsidiaries)
① Achieve carbon neutrality by 2039. To this end, reduce CO₂ emissions by 50% compared with FY2013 levels by 2030.
② Aim to achieve zero industrial waste by 2039. To this end, reduce the volume of industrial waste by 95% compared with FY2013 levels by 2030.

In March 2025, we also established a target of achieving carbon neutrality (Scope 1 and Scope 2) by 2050, covering NHK Spring as well as domestic and overseas consolidated subsidiaries.
