Integrated Information Disclosure Based on the Recommendations of the TCFD and TNFD

Based on the management philosophy of "Always creating new value, pursuing the realization of a sustainable society, and contributing to the happiness of humanity," Toyo Seikan Group has formulated the "Toyo Seikan Group Sustainability Charter" and promotes sustainability management across the entire group. Additionally, we have set the medium-term environmental goal "Eco Action Plan 2030" and are implementing various initiatives to reduce environmental impact. Regarding climate change initiatives, we expressed support for the recommendations of the "Task Force on Climate-related Financial Disclosures" (hereinafter "TCFD") in 2021, and for the conservation of natural capital and biodiversity, we began initiatives based on the "Task Force on Nature-related Financial Disclosures" (hereinafter "TNFD") starting in 2024. This page reports Toyo Seikan Group 's efforts on climate change and natural capital and biodiversity in accordance with the TCFD and TNFD's recommended disclosure frameworks.

Toyo Seikan Group has established a Group Sustainability Committee to oversee all group-wide sustainability-related activities, including addressing climate change and challenges related to natural capital and biodiversity. This committee, along with the Group Risk and Compliance Committee, is positioned as one of the key committees. This committee serves as a forum for discussions on matters related to promoting sustainability management, and in addition to managing progress on targets and plans, it reviews plans in light of social and international conditions, regulatory trends, and changes in the external environment, and considers new measures. This committee also manages progress management of the "Eco Action Plan 2030," which targets and plans related to climate change and natural capital and biodiversity. Additionally, Toyo Seikan Group recognizes various social issues in countries and regions, engaging in dialogue and collaboration with stakeholders such as customers, business partners, and local communities who use Toyo Seikan Group 's products and services, and works to solve social issues through its business activities.

Risk Management
Toyo Seikan Group Regarding overall risk management, the Group Risk and Compliance Committee checks the situation and implements improvements and preventive measures. Additionally, each group company formulates risk management policies and basic plans under its own promotion system, and compiles the company-wide risk management status. Environmental risks, including climate change and natural capital and biodiversity, are also discussed at Group Sustainability Committee and are treated as one of the Toyo Seikan Group 's key risks by the Group Risk and Compliance Committee.
Strategy: Climate Change
Referring to climate change scenarios published by organizations such as the IEA (International Energy Agency), we selected scenarios of 1.5~2°C and 4°C. Recognizing that the impacts of climate change will become apparent in the long term, we analyze the impact of climate change in 2050 as a time horizon.
Analyzed businesses: Packaging Business, Engineering, Filling and Logistics Businesses, Steel Plate Related Business, Functional Material Related Business
Scenario analysis
Transition Risk
In the 1.5~2°C scenario where climate change policies are introduced, we identified a cost increase risk of about 40 billion yen due to operating costs from carbon tax impositions and procurement costs for petrochemical raw materials and steel materials. As a response, we confirmed that GHG reduction aimed at carbon neutrality by 2050 and further promotion of the 3R for depletion and fossil resources can largely offset negative impacts.
In addition, Toyo Seikan Group is introducing an internal carbon pricing system (ICP) applying shadow prices, anticipating future carbon tax impositions and rising raw material prices. We set the carbon price at 10,000 yen per t-CO2 and utilize it for GHG reduction investments such as energy-saving equipment and renewable energy introduction, working toward achieving a roadmap toward a carbon-neutral society.
Physical Risks
Under the 4°C scenario, climate change has led to increased drought risks in areas with high water stress and increased flood risks due to more severe extreme weather events, potentially resulting in financial impacts exceeding 30 billion yen. We will establish a comprehensive water risk management system (to be operational from 2024) to mitigate these negative impacts.
Opportunity
In the 1.5~2°C scenario, we identified opportunities worth over 30 billion yen related to increased demand for environmentally friendly products and battery components for EVs and PHEVs. We will assess upcoming demand increases and prepare for strengthening production systems, striving to steadily turn these opportunities into Toyo Seikan Group growth.

Water risk assessment
Among the physical risks of climate change, drought risk and flood risk were confirmed to have a significant impact on Toyo Seikan Group 's management. Therefore, we conducted risk assessments targeting 93 major production sites in the group both domestically and internationally, using the water risk assessment tool Aqueduct developed by the World Resources Institute (WRI) and ENCORE developed by the Natural Capital Finance Alliance (NCFA). As a result, the six sites selected as priority sites were the following *.
Toyo Seikan Group focuses on sites with high risk identified in this evaluation to minimize water risks and contributes to solving water issues in each region.
| Water resource risk | 2 overseas bases |
|---|---|
| Regulatory and reputational risks | 1 overseas base |
| Flood risk | 3 domestic locations, 2 overseas locations |
Strategy: Natural capital and biodiversity
As part of our initiatives based on TNFD recommendations, we conducted assessments of all Toyo Seikan Group production sites and business activities regarding dependence and impact on natural capital and biodiversity.
Assessment of environmental risks arising from the location of business sites
Toyo Seikan Group conducted assessments of natural capital and biodiversity risks originating from each location using BRF* across all production sites. As a result, multiple risk factors were identified. Among physical risks, scores for "tropical cyclones (typhoons)" and "pollution" caused by the site location were particularly high, positioning them as risk factors that should be prioritized as Toyo Seikan Group countermeasures.
Regarding the risk of a "tropical cyclone (typhoon)," it can affect sites and the entire value chain in various ways, such as damage to land and buildings due to wind and rain, flooding inundation, and power outages. Therefore, risks such as temporary or long-term closure of production sites and loss of revenue are anticipated. Regarding the risk of "pollution" originating from the location, contaminated land, water, and air may cause product quality declines and employee health hazards.
Toyo Seikan Group will consider and implement risk reduction measures at each site to minimize the impact of these risks.

- The Biodiversity Risk Filter (BRF) is an online tool announced by the World Wide Fund for Nature (WWF) at the World Economic Forum (Davos Conference) in January 2023 to screen and prioritize biodiversity-related risks in a company's business or supply chain.
Relationship between business activities and natural capital/biodiversity
We evaluated the impact of Toyo Seikan Group 's business activities on natural capital using ENCORE.
As a result, it was revealed that 'discharge of hazardous pollutants into water and soil' has the greatest impact on the natural environment. Additionally, factors such as 'disturbances (noise, light, etc.)' and 'greenhouse gas emissions' have also been identified as influencing factors in Toyo Seikan Group 's business. To reduce these risks, Toyo Seikan Group systematically implements disaster prevention measures for land and buildings at each site, as well as measures to prevent waste leakage. This helps limit the scope and extent of damage to assets and surrounding environments during natural disasters or accidents, aiming to reduce the time and cost required for recovery. Furthermore, strengthening such proactive risk management is believed to help suppress increases in product liability insurance and liability insurance premiums.
