The Nitto Group’s response to climate change

Recognizing that responding to climate change is an important management issue, the Nitto Group has strategically included such responses in its management agenda and announced its support for the recommendations by the Task Force on Climate-related Financial Disclosures (TCFD) in May 2022. After announcing our support, every year, we assess the impact that climate-change-related risks and opportunities may have on our business and make revisions as necessary. In fiscal years 2025 and 2026, we have further accelerated our response to climate change and, in order to enhance its effectiveness, established new targets and indicators, including GHG emission reduction targets by scope.

Governance

The Nitto Group has set “responding to climate change” as one of its material issues for sustainability and is strengthening its efforts to combat climate change. The Group is formulating and promoting short- to medium-term and long-term strategies including environment for each issue by establishing a sustainability governance system, where the Corporate Strategy Meeting body (the President and COO serves as the chair of the Corporate Strategy Meeting) plays the central role under the direction and supervision of the Board of Directors (the Chairman of the Board and CEO serves as the chair of the Board of Directors). In addition, in order to increase the effectiveness of environmental initiatives including climate change response, the Group has established the Global Green Committee led by the Vice President in charge of promoting climate change-related issues and strengthen cross-organizational coalitions while examining strategies and implementing and promoting countermeasures against the issues. The Nitto Group's governance structure is as follows:
The Group places ESG (Environment, Society and Governance) at the core of its management. As such, rather than establishing a general sustainability committee or ESG committee, we use the Corporate Strategy Meeting, chaired by the President & COO and comprising of all Vice Presidents, as a platform to discuss the promotion of ESG management. This enables us to incorporate ESG into management in a swift and appropriate manner, and to achieve governance that ensures higher feasibility by integrating the company’s sustainability and growth strategy.

Role of the Board of Directors

The Board of Directors makes decisions on important matters, for instance, management policies, management indicators and targets related to the environment including climate change (future-financial indicators), such as the mid-term management plan and support for external initiatives. Each quarter, it provides periodic directions, and conducts supervision, concerning the climate change targets (future-financial indicators) of the mid-term management plan as well as the status of progress toward target achievement, and, as necessary, adds new items to the agenda if a material matter arises.
The Board of Directors is comprised of Directors who possess qualifications, knowledge, and experience related to sustainability, including climate change, and who thus impart it with a sustainable and greater supervision function.
Please see the section below for the skills of each Director.

Policies related to the Board of Directors (members) and the Board of Corporate Auditors (members) Nitto Group Integrated Report 2025(P.59 Skills Matrix)

Role of the Corporate Strategy Meeting

The Corporate Strategy Meeting is responsible for deliberation and decision-making regarding specific policies and measures for action based on management policies and management indicators regarding the environment including climate change, as well as managing risks and opportunities and monitoring progress towards achieving targets on a monthly basis. It provides periodic reports––on a quarterly basis––to the Board of Directors on its deliberations and decisions and the progress of initiatives, and, as necessary, provides additional reports if a material matter arises. Additionally, to ensure that the matters deliberated and decided are promptly disseminated throughout the company, the Corporate Strategy Meeting comprises all Vice Presidents who are in charge of business execution departments, special function departments, and regional management.

Role of the Vice President and department in charge

We appoint the Vice President in charge of promoting environmental initiatives including climate change, and also have special function departments responsible for implementing those initiatives that serves as a department in charge of the environment. The department regularly assesses the risks and opportunities related to climate change, considers strategies (including transition plans), as well as executes and promotes measures to tackle climate change issues. The Vice President manages the results of these assessments, the details of their consideration, and their implementation and promotion.
In order to enhance the feasibility of climate change initiatives, we have established the Global Green Committee that is managed by the Vice President in charge of promoting climate change initiatives, aiming to strengthen cross-organizational cooperation among the various functional departments involved, including departments promoting ESG management in general, procurement departments, business execution departments, and regional management. The major activities of the Global Green Committee are as follows:
The progress of these initiatives is periodically reported to the Corporate Strategy Meeting primarily by the department in charge of the environment.

The major activities of the Global Green Committee

Risk and opportunity management

The Group appropriately manages key risks and opportunities related to climate change that management recognizes may significantly impact its business activities, and implements comprehensive management across the Group by combining them with other key risks that also significantly impact its business activities.

Risk/opportunity assessment and selection process

Regarding key risks and opportunities related to climate change in business activities, the Group understands the impact of changes in the internal and external environment; evaluates and identifies(selects) relative importance based on the “magnitude of impact” on business in the case of an incident and the “possibility of occurrence”; and determines the priority of the risks and opportunities.
We utilize scenario analysis to identify the risks and opportunities associated with the shift to a low-carbon economy that are expected due to climate change, as well as the risks of physical damage posed by factors such as extreme weather, for not only Nitto but the entire value chain stretching from our suppliers to customers, and then make a qualitative and quantitative assessment of the possible financial impacts.

Risk/opportunity management process

The Nitto Group appropriately manages the identified major risks and opportunities associated with environment issues including climate change under the Risk Management Promotion System below.

The key risks and opportunities related to the environment issues including climate change will be monitored by business execution departments and regional managers in collaboration, while the department responsible for environmental issues will assume responsibility for managing them. Information regarding monitored risks, together with information managed by other special function departments, will be reported and deliberated monthly at the Corporate Strategy Meeting, which consists of Directors and Vice Presidents. The results of the deliberation will be instantly instructed to each responsible department and countermeasures will be promptly taken to strengthen controls. The progress of the implementation and improvement will be again reported to the Corporate Strategy Meeting to increase the effectiveness of the Group management.
At the end of the fiscal year, the department in charge of the environment, as the department responsible for the environment management, conducts a self-evaluation on the major risks associated with the environment issues including climate change that were reported and reviewed in the Corporate Strategy Meeting in accordance with evaluation criteria such as the implementation structure establishment, controls and preventative measures implementation, and the occurrence of incidents as well as the responses to them. The department in charge of risk management evaluates the results of the self-evaluation from an independent viewpoint. The risk management department and the Vice President in charge of risk management independently conduct evaluations based on established criteria and report the results to the Corporate Strategy Meeting and the Board of Directors.

Integration with group-wide risks

As a group, we manage risks and opportunities related to the environment issues including climate change comprehensively by integrating them with other major risks that significantly impact our business operations. We assess the relative importance of individual risks by analyzing them using a graph with two axes––a vertical axis representing the “degree of impact” on our business in case of occurrence or manifestation, and a horizontal axis representing the “probability of occurrence”––and recognize the significance of climate change risks among group-wide risks. We categorize these group-wide risks into “business risks,” which are associated with our businesses, and “operational risks,” which can generate group-wide impact, and implement appropriate risk management on a group basis. The major group-wide risks in fiscal 2024 are as follows. Please see here for more details.

Business Risks

Strategy

In line with external trends, as exemplified by the conclusion of the 2015 Paris Agreement and the Japanese government’s carbon-neutral declaration, the Group carried out a scenario analysis regarding transition risks and physical risks and opportunities expected due to climate change across the entire value chain, which includes not only the Group but also its suppliers and customers. The results of the scenario analysis have been incorporated into 2030 management indicators, including Nitto Group Carbon Neutral 2050, and into the mid-term management plan Nitto RISE 2028. The Group has promoted initiatives to remove solvents, save energy, use renewable energy, and create products that contribute to the environment, and confirm that it would be able to minimize risks and maximize opportunities, and that the strategy would be useful.
The Group recognizes “responding to climate change” as its material management issue and strategically incorporates them into its management.

Definition of scenarios

We forecast the impact that changes in the business environment caused by climate change may have on our businesses and management, and then create scenarios based on this. We consider the “1.5°C scenario,” under which the average global temperature does not exceed that of preindustrial times by more than 1.5°C by 2050, and the “4°C scenario,” under which the average global temperature is likely to exceed that of preindustrial times by 3.2 to 5.4°C by 2050.
These scenarios are created based on information published by the international organizations indicated below. The business environment assumed in each scenario is as follows.

[1.5℃ Reference Scenario]
References: IEA NZE 2050 (Net Zero Emissions by 2050 Scenario in IEA's World Energy Outlook 2023) and RCP2.6, etc.
[4℃ Reference Scenario]
References: IEA STEPS (Stated Policies Scenario in IEA's World Energy Outlook 2023) and RCP8.5, etc.

Business impact (financial impact)

We identify the risks and opportunities in the short term (less than three years), medium term (three to five years), under the business environment assumed in the respective scenarios. The short-term and medium-term risks and opportunities are reflected in the mid-term management plan. For the long-term risks and opportunities, we conduct a financial quantitative analysis to identify the business impact (financial impact) in the event that the respective scenarios materialize. The business impacts in the medium and long term are as follows.

Type of risk/opportunity Event Assumed risks and opportunities Impact calculation item 1.5℃ 4℃
2030 2050 2030 2050

Monetary impact Small: less than 3 billion yen; Medium: 3 to less than 10 billion yen; Large: 10 billion yen or over.
Those marked with a hyphen are not evaluated as the business impact is expected to be minimal.

Under the 1.5°C scenario, the major factors of profit decline are as follows: increase in transition costs (raw material costs) to low GHG-emitting raw materials, increase in taxation costs (operating costs) due to the increased introduction of carbon taxes and carbon levies, and increase in petroleum-derived raw material costs due to carbon taxes and other taxes in the upstream of the value chain passed on to raw materials.
On the other hand, we expect revenue from products contributing to the environment (PlanetFlags products) to increase due to increased demand for recycled products.
Under the 4°C scenario, the major factors of profit decline are as follows: increase in petroleum-derived raw materials procurement costs due to soaring fossil fuel prices, and damage to the company’s buildings, facilities, infrastructure, etc., plant shutdowns, and lost opportunities (decrease in revenue) due to a flood, high tide, etc. On the other hand, we expect revenue from medical-related products, from among our products contributing to human life (HumanFlags products), to increase with the increase of health damage, such as infectious diseases due to rising average temperature.

Responses to risks and opportunities

We have reviewed our responses to risks and opportunities under the respective scenarios.

Responses to risks (risk minimization)

Under the 1.5°C scenario, we will take the following measures to minimize risk: promote energy saving in the manufacturing process by shifting to solvent-free processes, achieve energy saving by improving infrastructure and utility efficiency, and strive to utilize fully renewable energy. Furthermore, by promoting the development of recycled materials in cooperation with our suppliers, we will reduce the usage of raw materials through the effective procurement of sustainable materials and effective utilization of resources.
These measures will enable the reduction of GHG emissions, which will in turn enable us to mitigate the increased taxation costs by approximately 50% due to the increased introduction of carbon taxes and carbon levies by 2030. Since we expect to achieve carbon neutrality in our GHG emissions (Scope 1 and 2) by 2050, we do not believe our costs will increase.
Additionally, as we can reduce our power purchases by energy saving and using renewable energy, we believe it will be possible to mitigate the increase in capital expenditures due to the development and introduction of high energy-efficient technologies by approximately 50% by both 2030 and 2050.

Under the 4°C scenario, we will take the following measures to minimize risk: reduce the usage of raw materials through the effective utilization of resources and develop preemptive prevention measures through the promotion of business continuity management (BCM) across Nitto Group business locations. We believe these measures will enable us to mitigate the increase in petroleum-derived raw materials procurement costs due to soaring fossil fuel prices, as well as the damage to the company’s buildings, facilities, infrastructure, etc., plant shutdowns, and lost opportunities due to a flood, high tide, etc. by both 2030 and 2050.

Responses to opportunities (opportunity maximization)

Under the 1.5°C scenario, we will work on expanding our lineup of products contributing to the environment (PlanetFlags products) in order to maximize opportunities. We expect revenue from products contributing to the environment to increase due to increased demand for low-carbon products such as recycled products.

Similarly, under the 4°C scenario, we will work on expanding our lineup of products contributing to human life (HumanFlags products). We expect revenue of medical-related products due to an increase in health damage, such as infectious diseases due to rising average temperatures.

We believe we will be able to maintain a certain level of profit by consistently creating PlanetFlags and HumanFlags products.

Please see here for PlanetFlags & HumanFlags.

The results of the scenario analysis have been incorporated into 2030 management indicators, including Nitto Group Carbon Neutral 2050, and into the mid-term management plan Nitto RISE 2028, confirming the effectiveness of the strategy.
Our 80-billion-yen investment for decarbonization over the ten-year period from 2021 to 2030 is being directed primarily to minimize the risks assumed in the 1.5°C scenario: shifting to solvent-free processes, improving infrastructure and utility efficiency, and using renewable energy. Scenario analysis has shown that these measures will enable us to save more than 10 billion yen in costs in 2030 on a single-year basis. Therefore, we believe the expected benefits make it a reasonable investment.
We consider this as validation of the resilience of our strategies for both the 1.5°C scenario and 4°C scenario, and will aim to minimize risks and maximize opportunities even further moving forward.

Indicators and Targets

The Group has set “responding to climate change” as one of its material issues for sustainability and believe that reducing GHG emissions, a cause of global warming, is essential for a sustainable growth and the realization of a sustainable environment and society, and that it is an important social responsibility. Therefore, the Group aims to achieve carbon neutrality in our GHG emissions (Scope 1+2) by 2050, and has declared the “Nitto Group Carbon Neutral 2050” initiative.
In addition, the Group ensures that the countermeasures are implemented to minimize risks and maximize opportunities and has established 2030 management indicators and targets to regularly monitor and manage the progress of those countermeasures. In order to achieve our ideal state through the resolution of Material Issues for Sustainability, the Nitto Group as a whole has established “GHG emissions,” “Renewable energy ratio,” “Resource utilization ratio,” “Sustainable materials procurement ratio,” and “Flags revenue ratio” as materiality KPIs.
Moreover, for “GHG emissions (Scope 1+2)”, which the overall target is 400 thousand tons*1, the Group has set individual targets for fiscal 2026—330 thousand tons for “GHG emissions (Scope 1)” and 70 thousand tons for “GHG emissions (Scope 2)”—to enhance the effectiveness of activities.
Although we have previously focused on improving our waste plastics recycling ratio, given that plastics account for roughly half of our total waste, we newly introduced the “Resource utilization ratio,” in the fiscal 2025, to promote the active circular use of a broader range of resources beyond plastics.

*1 In August 2024, we set science-based GHG emissions reduction targets (Scope 1+2 and Scope 3) aligned with the 1.5°C pathway and obtained the SBT (Science Based Targets) certification.

Management of indicators and targets

We enhance the feasibility of the indicators and targets for each risk and opportunity by not only implementing management on a group level, but also by allocating group targets to the business execution departments, setting individual targets for each business execution department, and developing business-specific measures in addition to group-wide measures. Each business execution department confirms the progress toward target achievement monthly; the department in charge of the environment manages the progress on a group-wide basis and provides a report to the Corporate Strategy Meeting. The indicators and targets are reviewed once a year to make any necessary revisions depending on the progress status or changes in the external environment. Further, the future-financial indicators are reviewed when we update the mid-term management plan once every three years, and revisions are made following review and decision by the Board of Directors.

Progress toward our targets

■Efforts and progress regarding GHG emissions (Scope 1 and 2)

The Nitto Group has thus far worked to reduce its energy consumption as part of its efforts to reduce GHG emissions. For example, we are advancing multifaceted energy‑saving initiatives, including the shift to solvent‑free products, the effective utilization of waste heat, and the introduction of high‑efficiency equipment. We are also continuing medium‑ to long‑term procurement through the use of Power Purchase Agreements (PPAs) and promoting the transition to renewable energy.
Going forward, we will work toward achieving our 2030 targets—330,000 tons for GHG emissions (Scope 1) and 70,000 tons for GHG emissions (Scope 2)—by reducing GHG emissions across our supply chain and advancing the planned procurement of corporate PPAs.

■Efforts and progress regarding GHG emissions (Scope 3)

We are currently examining reduction measures to achieve our 2030 target of 1,460 thousand tons for GHG emissions (Scope 3). Specifically, we are estimating the reduction effects of transforming our business portfolio, improving yield, and switching to sustainable materials and incorporating these into our reduction measures. For raw materials and transportation, the cooperation of our suppliers is essential. We have been promoting supplier engagement activities and, in fiscal 2025, improved calculation accuracy by obtaining primary data on raw materials from our suppliers.
Going forward, we will continue to discuss the Scope 3 categories with a focus on those with high emissions together with business execution departments through the Global Green Committee and take timely actions.

Target categories: 1. Purchase of raw materials, 3. Fuel production and electricity generation, 4. Transportation (purchase and outbound logistics), 5. Waste disposal, 12. Product disposal

Efforts and progress regarding waste plastics recycling ratio and the resource utilization ratio

We have been advancing the development of plastics recycling technologies. In fiscal 2025, we invested approximately 100 million yen to install demonstration facilities at the Toyohashi Plant and have been advancing efforts to address further technical challenges. This time our uniforms made using recycled plastic have been completed, and we have begun using them within the company.
Going forward, we will work to improve the resource utilization ratio by further promoting more efficient use of resources through yield improvement and waste recycling.

Indicator FY2023 FY2024 FY2030 Target (long term)
Resource utilization ratio - 66% 69%

■Efforts and progress regarding sustainable materials procurement ratio

In fiscal 2025, we expanded the scope of aggregation to a global basis, thereby reflecting the performance of the EMEA region, where the procurement ratio of biomass‑derived raw materials such as pulp is high. Additionally, as part of our transition to sustainable materials, we began procuring polysulfone and ethyl acetate certified under the mass balance approach*5, and at certain sites in the EMEA region, we have switched to 100% biomass‑derived ethyl acetate.
Going forward, we will continue to promote the transition to sustainable materials by further advancing our raw material strategy and strengthening collaboration with our suppliers.

■Efforts and progress regarding flags revenue ratio

As concerns about climate change continue to grow, the development of PlanetFlags p products that help address environmental issues is becoming increasingly important and urgent. For this to happen, we must seek collaboration with partners within and outside the company. Through the avenue of the Global Green Committee, which facilitates the decarbonization and resource recycling processes by way of technological changes, we will create new PlanetFlags products with the three axes of business divisions, regional headquarters, and functional departments cooperating organically. At the same time, we will work closely with business partners and suppliers to take diverse measures to accelerate the commercialization process, including gaining a stake in startups and venture businesses.

Sustainability Data Book

In addition, of the 80 billion yen in decarbonization investments being promoted from 2021 to 2030, 37.2 billion yen in decarbonization-related investments are being carried out over the five-year period from fiscal 2021 to fiscal 2025.
These are mainly used for energy conservation through improvements in equipment operations and upgrades to high-efficiency equipment, as well as for increasing the use of renewable energy through the installation of new solar power generation facilities and the expansion of existing ones.

The Nitto Group has implemented environmental investment based on internal carbon pricing (ICP) in order to ensure achievement of the 2030 Management Targets (GHG emissions) committed in Nitto Group Carbon Neutral 2050. We are promoting investment, primarily in new environmental technology and facilities, at an assumed internal carbon price of 10,000 yen/t-GHG based on consideration of EU-ETS and other external trends.
