Astellas believes that maintaining a healthy global environment is an essential theme for building a sustainable society, and it is also an important element in ensuring the continuation of business activities. For Astellas to achieve sustainable growth, we must fulfill our corporate social responsibilities regarding issues that impact the local environment, including climate change problems, environmental pollution, and waste disposal. Astellas strives to develop its aspirations for the company based on a long-term timeframe and global perspective. At the same time, we continue efforts to address regional social issues and pursue corporate activities in harmony with the global environment.
Supervisory structure
The Board of Directors views climate change countermeasures as a key sustainability issue and reviews the progress of initiatives on a quarterly basis. Astellas Sustainability submits annual reports to the Board each fiscal year to facilitate the monitoring of these initiatives, including efforts to address climate change. Through this monitoring process, the Board oversees the effectiveness of management.
Executive structure
Sustainability issues are recognized as top priorities for Astellas, with key performance indicators (KPIs) established and monitored. For climate change, progress is assessed through greenhouse gas emission reduction targets and KPIs, which are aimed to be met by 2030. The adoption of renewable energy is also a crucial metric for measuring progress. The Sustainability Committee, chaired by the Head of the Sustainability Department and reporting to the Chief Strategy Officer (CStO), manages the Environmental Action Plan. The Committee reviews Astellas' Environmental Action Plan every five years to ensure its continued relevance and to suggest improvements as needed. Additionally, the Committee evaluates long-term plans for greenhouse gas reduction initiatives and the content of the Company’s TCFD disclosures.
The system works by having the management of risks related to the environment monitored in terms of sustainability by functional units and reports periodically made to the CStO, who issues instructions as necessary. The Executive Committee†, chaired by the President and Chief Executive Officer, or the Board of Directors discuss and determine how identified risks are to be addressed in accordance with the importance of the issue in question.
Astellas is committed to the sustainable enhancement of corporate value and aims to be a company that is selected and trusted by all stakeholders—including patients, shareholders, employees, and the environment and society—in order to achieve this goal. The Astellas Code of Conduct states: “We strive to minimize our environmental impact and address global challenges, such as climate change and resource recycling, by conducting business sustainably.”
Astellas conducts a materiality assessment to identify and prioritize the issues most important to society and its business, using the results as guidance for its sustainability initiatives. In the Astellas Materiality Matrix established for the fiscal year ended March 2022, “Climate Change and Energy” was recognized as “Very Important” from both societal and Astellas perspectives. In the updated materiality identified in 2026, environmental sustainability was designated as one of the material topics. As key KPIs to monitor progress on climate change measures, the company has set targets for greenhouse gas (GHG) emissions (Scope 1+2 and Scope 3).
Recognizing net zero by 2050 as a societal goal, Astellas set its 2030 targets using a backcasting approach. Since 2018, Astellas’ GHG emission reduction targets have been certified by the Science Based Targets initiative (SBTi) as aligned with the Paris Agreement’s 2°C pathway. The current targets, announced in January 2023, set fiscal year 2030 as the target year with fiscal year 2015 as the base year, and have been approved by SBTi as consistent with the 1.5°C pathway (Scope 1+2) and the well-below 2°C pathway (Scope 3).
To achieve these targets, Astellas is implementing measures such as the use of renewable electricity (including installation of solar panels at its own sites and the use of off-site corporate PPAs), adoption of low-emission vehicles for its sales fleet, and promotion of engagement with value chain partners.
To achieve net zero by 2050, Astellas aims to reduce emissions from its operations by 90%, while considering the neutralization of residual emissions as a long-term challenge. Potential neutralization measures include technologies such as Carbon Dioxide Removal; however, which technologies will be utilized remains a future issue, and neutralization measures have not yet been implemented at this stage.
The 2030 GHG reduction targets and the 2050 net zero policy were approved by the Executive Committee in January 2023. Efforts to address environmental issues for achieving these targets are included as one of the sustainability goals and are evaluated as part of the calculation of executive bonuses (short-term incentive compensation), and are taken into account when assessing the achievement of overall corporate management strategies.
Astellas’ GHG emission reduction targets consist of combined Scope 1 and Scope 2 targets, as well as Scope 3 targets.
| Item | Targets |
|---|---|
| Scope 1+2 | Reduce GHG emissions (Scope 1 + Scope 2) by 63% by fiscal 2030 (Base year: fiscal 2015) [1.5°C target] |
| Scope 3 | Reduce GHG emissions (Scope 3) by 37.5% by fiscal 2030 (Base year: fiscal 2015) [well below 2°C target] |
Reduction of Scope 1 and Scope 2 emissions is primarily driven by the adoption of renewable electricity. Solar power generation facilities installed at Astellas sites have been promoted at locations such as the Tsukuba Research Center, the Kerry Plant, the Dublin Plant, and the Shenyang Plant. The procurement of renewable electricity is also being promoted at facilities including the Takahagi Technology Center, Tsukuba Research Center, Tsukuba Bio Research Center, Toyama Technology Center, Yaizu Technology Center, Dublin Plant, Kerry Plant, and Universal Cells.
Astellas is also advancing engagement with value chain partners to support their GHG emission reductions. To date, the company has increased awareness of its initiatives through online meetings with partners with high procurement spending and is promoting the use of GHG emissions data (primary data) calculated by business partners.
Progress toward SBT targets calculated in accordance with the GHG Protocol is as follows:
Progress on Environmental Action Plan (Scope 3)
| Metric | Boundary | Unit | FY2015 | FY2023 | FY2024 | FY2025 |
|---|---|---|---|---|---|---|
| Scope3 GHG emission | Global | t-CO2e | 1,378,972 | 1,121,350 | 1,276,323 | 1,123,857 |
| ％ reduction(vs 2015) | Global | % | - | -19% | -7% | -19% |
Physical Risks (Acute / Chronic)
Scenario analysis was conducted with reference to the TCFD risk classification.
| Acute | Operations halt at our business sites due to floods or other factors.Raw material and product supply is delayed due to damage in the supply chain caused by floods or other factors |
| Chronic | Droughts will affect the operations of our plants and supply chain, resulting in delays in product shipments rising average temperatures will have an impact on energy costs accompanying operation of air conditioners at business sites. |
Transition risks (regulatory, technological, demand, reputation)
We also referred to the TCFD risk classification for transition risks.
| Policy and Legal | Business sites that have not introduced renewable energies may have to add payment of a carbon tax to their costs |
Obsolescence and impairment loss on existing facilities accompanying GHG emission regulations
| |
| Technology | Costs arise when investing in low emission equipment |
| Market | Rising energy and raw material prices lead to higher costs exacerbated by inflation |
Astellas has established a cross-functional internal team for information disclosure and conducts scenario analysis. Based on the assumption that transition risks will materialize under a 1.5°C scenario and physical risks under a 4°C scenario, Astellas analyzed climate change-related risks and opportunities affecting its business. The results of the analysis were reviewed by the Sustainability Committee.
The time horizons covered by the analysis are short term (1 year), medium term (1–5 years), and long term (over 5 years). Since fiscal year 2021, climate-related risks and opportunities have been analyzed annually. In fiscal years 2024–2025, physical risk analyses were conducted for Astellas’ major sites and across its value chain.
In the physical risk assessment conducted in 2025, the scope of analysis included not only Astellas’ own sites (20 locations), but also CMOs (19 locations) involved in the manufacture of active pharmaceutical ingredients for key products, as well as major logistics hubs (20 locations covering 15 key markets).
As widely recognized scenarios, Astellas refers to IPCC scenarios. For physical risk analysis, the high-emission scenario SSP5-8.5 was used as a reference. For transition risk analysis, the SSP1-1.9 and SSP1-2.6 scenarios were used as references. In selecting the reference scenarios, Astellas considered sources such as the IPCC Sixth Assessment Report (AR6), the IPCC Special Report “Global Warming of 1.5°C,” and the International Energy Agency (IEA) report “Net Zero by 2050.”
Under the SSP5-8.5 scenario referenced in the physical risk analysis, the average global temperature increase by the end of the 21st century is assumed to be approximately 4.5°C compared to pre-industrial levels. This scenario assumes continued intensive use of fossil fuels, along with large-scale industrialization and infrastructure development, with low prioritization of decarbonization-related technological innovation.
The SSP1-1.9 and SSP1-2.6 scenarios referenced in the transition risk analysis assume average temperature increases of approximately 1.5°C and well below 2°C, respectively. These scenarios are based on the implementation of policies that promote decarbonization, along with advancements in technologies necessary to achieve a decarbonized society, including carbon neutralization measures.
The physical risk analysis covered Astellas’ major sites (manufacturing plants, research facilities, and key offices) as well as its value chain. The transition risk analysis covered the entire Astellas Group. Most of the sites included in the assessment are located in East Asia, North America, and Europe.
Physical Risk
In the risk matrix analysis, the Astellas facility with the highest risk was the Shenyang Plant. In the 4°C scenario, increased risks of flood, heat, and precipitation in 2050 were detected as potential issues.
Note: The impact of the physical risks were analyzed based on where each site is located at a 90-meter grid resolution and thus currently-installed risk mitigations were not taken into consideration; therefore, actual impact could be different from the estimated loss herein.
The Risk Score is a normalized estimate of the average risk posed by each hazard. It is calculated using the one to three hazard metrics depending on the hazard under a 4°C scenario. For example, precipitation risk refers to 1-day maximum precipitation in a 1 in 100-year event, and wildfire risk refers to the annual wildfire probability.
Key hazards that have the potential to have the potential to affect Astellas
Precipitation
An increase in instances of heavy downpours across all sites is included in this analysis. At the location of Yaizu Technology Center, heavy rainfall of a once-in-50-year level was estimated at 357 mm per day in the 2020 model and 398 mm in the 2050 model using the 4°C scenario.
Changes in maximum precipitation per day with the highest risk
| Site Name | Location | Max precipitation in one day >4°C scenario (mm) | |||||
| 10-year return | 50-year return | ||||||
| Modelled 2020 baseline | 2050 | % change | Modelled 2020 baseline | 2050 | % change | ||
| Yaizu Technology Center | Japan | 252 | 279 | 10 | 357 | 398 | 12 |
Flood
The location of Toyama Technology Center is particularly concerning due to the potential for floods reaching up to 8.5 meters, which could occur once in a hundred years. Astellas should assess the flood risk measures at high-risk sites to consider they are reasonably prepared to address potential flood risks by 2050.
Heat waves
Heat is not currently a major risk to Astellas, on a scale of 1-100, the average current risk is 29. However, it has been suggested that heat risk may become apparent in the 4°C scenario by 2050. At the location of Astellas Gene Therapies Sanford, it was estimated that in 2050, the number of days per year with maximum temperatures exceeding 35°C will be 41. Worker productivity can be significantly impacted by heatwaves if buildings are not sufficiently cooled.
Astellas sites for days above 35°C in 2050 under a >4°C scenario
| Site Name | Location | Days above 35°C per year | % Change from Baseline |
| Astellas Gene Therapies- Sanford | USA | 41 | 78 |
High winds
Strong winds can cause extensive damage to buildings if they are not designed to withstand these storms. However, Japan has stringent building regulations which ensure that structures are designed to withstand wind speed loads that are determined based on their location, height and intended use.
Sites with wind gusts over 200 km/h in 1 in 100-year events in 2050
| Site Name | Location | Wind Gusts |
| Yaizu Technology Center | Japan | 232 |
Others
Cold has the highest current risk score, however the risk becomes much lower for all sites by 2050. Wildfire is of concern at one 3PL site and Hail/Thunderstorms do not pose a high risk to any locations.
Transition Risks (Policy, Technology, Market and Reputation)
As transition risks, Astellas conducted scenario analysis on factors such as carbon pricing burdens, capital investments required for climate change countermeasures, and increases in electricity prices. For potential impacts and other details, please refer to the table in the next section.
| Climate-Related Risks | Potential Impacts | Financial Impacts | Affected Period | Astellas’ Resilience |
|---|---|---|---|---|
| Transition Risks (risk materializing at 1.5°C increase) | ||||
| Policy and Legal | ||||
| Increased pricing of GHG emissions (costs if paying a carbon tax) | Business sites that have not introduced renewable energies may have to add payment of a carbon tax to their costs. | Scope 1+2: 1.1 billion yen in FY2030, assuming a carbon tax of $100 per ton | Medium to long-term | Some of the electricity consumed at the business site is generated internally by using renewable energy sources such as wind power and solar power. |
| Scope 3: 10 billion yen in FY2030 assuming a carbon tax of $100 per ton | Medium to long-term | Scope 3 Category 1: We will work on optimizing the use of raw materials. By formulating a supply chain sustainability roadmap, CO2 emission data of purchased products will be analyzed and emission reduction will be prioritized. | ||
| Obsolescence and impairment loss on existing facilities accompanying GHG emission regulations | Possibility of being asked to discard facilities and assets due to strengthening of environmental regulations. Refrigeration equipment using freon gas and vehicles that use fossil fuels may no longer be available in some countries after 2035. | No significant impact | Medium to long-term | There are no existing facilities or assets that we are required to dispose of at this moment. Regarding freon gas, we will take appropriate measures that comply with laws and regulations. From 2030 onwards, we need to respond to a required change in automotive vehicles (shift from internal combustion engines to electric motors / EVs and fuel cells). Shift to EVs for sales fleets and trucks and modal shift of transportation will have an impact on business operations. |
| Technology | ||||
| Costs to transition to lower emissions technology | Costs arise when investing in low emission equipment. | 1.2 billion yen Based on past climate-change investment plan | Short to long-term | Select and invest in efficient projects to reduce the carbon tax burden. Explore non-investment alternatives, such as power purchase agreements, for significant projects like solar panel electricity generation. |
| Market | ||||
| Increased energy consts | Rising energy and raw material prices lead to higher costs exacerbated by inflation. | An increase of 10 yen per 1 kWh unit of electricity will increase the cost burden by 2 billion yen. | Short to long-term | Increasing electricity and energy costs consumed at business sites due to regulatory changes would be an issue in the future. However, we do not envisage a significant increase in the cost of raw materials for drug production due to climate change. We will reduce the impact of rising fossil fuel prices by using renewable energy-derived power. |
| Physical Risks (risk materializing at 4 ℃ increase) | ||||
| Acute | ||||
| Increased severity of extreme weather events such as floods | Operations halt at our business sites due to floods or other factors. Raw material and product supply is delayed due to damage in the supply chain caused by floods or other factors. | 500 million yen Reference: the flood countermeasures of the Toyama Technology Center. | Short to long-term | The planned investment for the Toyama Technology Center’s flood response was estimated to be 500 million yen and comprises the following - Install a 3m waterproof wall around the power receiving building - Construction of substation equipment with a structure of 3m or more - Purchase of generators If similar measures are required, a similar amount of investment will be considered. |
| Chronic | ||||
| Changes in precipitation patterns Rising mean temperatures | Droughts will affect the operations of our plants and supply chain, resulting in delays in product shipments. Rising average temperatures will have an impact on energy costs accompanying operation of air conditioners at business sites. | No significant impact | Short to long-term | According to IPCC AR6 SPM SSP3-7.0 scenario, global sea level change in 2050 relative to 1900 is less than 0.5m. This level of change has no significant business impact. Changes in precipitation patterns do not have a material impact on Astellas’ operations. The analysis of the rise in average temperatures is described in the next section. |
| Climate-related opportunities | Potential Financial Impacts | Affected Period | Astellas’ response | |
|---|---|---|---|---|
| Resource efficiency | Use of more efficient production and distribution processes Use of recycling | Reduced operating costs | Short to long-term | In order to maintain a stable supply of pharmaceuticals even during pandemic of infectious disease or natural disasters such as earthquakes, storms, and flooding, three logistics centers are operated in Japan. In European countries and the United States, warehouses shared by multiple pharmaceutical manufacturers are being used to streamline the distribution process. We collect exhaust heat from air conditioning units at manufacturing plants and research sites and use it to pre-heat the air supply to improve heat efficiency. |
| Energy source | Use of lower-emission sources of energy | Reduced exposure to GHG emissions and therefore less sensitivity to changes in cost of carbon | Short to long-term | Shifted boiler fuel from liquid fuel to gaseous fuels. We are moving ahead on introducing hybrid and electric vehicles in our sales fleet. We are working on using wind power generation and biomass boiler system at Kerry Plant in Ireland. |
| Products and markets | Development and/or expansion of low emission goods new products and services Access to new markets | Increased revenues by responding to changing needs | long-term | Climate change can change the geography of the morbidity associated with and severity of epidemics. Heart disease, respiratory disease, etc. may also increase. |
From the scenario analysis, no significant vulnerabilities were identified that would have a critical impact on Astellas’ business for either physical risks or transition risks. This suggests that the promotion of renewable energy utilization contributes to resilience against the potential increase in carbon tax burdens in the future.
The temperature increases presented in the IPCC scenarios are estimated with a range of uncertainty. In Table SPM.1 of the IPCC AR6 Summary for Policymakers, the projected temperature rise for 2041–2060 under the SSP5-8.5 scenario is a best estimate of 2.4°C, with a very likely range of 1.9–3.0°C. Under the SSP1-1.9 scenario, the projected temperature rise for 2041–2060 is a best estimate of 1.6°C, with a very likely range of 1.2–2.0°C.
SSP5-8.5 is an extreme scenario in which high emissions continue under sustained dependence on fossil fuels, and there is uncertainty regarding the persistence of such dependence. In the SSP1-1.9 and SSP1-2.6 scenarios, there are uncertainties regarding the introduction of policies to restrict fossil fuel use (such as high carbon taxes), as well as the realization of technological developments necessary to achieve net zero, such as Carbon Dioxide Removal.
Capital investments for climate change measures, such as the installation of solar power generation facilities, are being carried out within the scope of capital expenditures for pharmaceutical manufacturing facilities, and financing specifically for climate change measures (such as the issuance of green bonds) is not assumed.
No situation is anticipated in which existing facilities would need to be repurposed or retired due to climate change measures. When updating facilities, efforts are made to introduce equipment with superior environmental performance.
A recent major investment is the Tralee plant currently under construction in Ireland. The new plant is being built in line with Astellas’ sustainability principles and incorporates best practices in energy and environmental design. Compared with the LEED® baseline, the plant aims to reduce water usage by approximately 50%, decrease operational energy intensity by more than one-third, and achieve zero landfill waste. Therefore, this investment is expected to strengthen Astellas’ resilience.
As outlined in the Position on Climate Change, Astellas is committed to fulfilling its environmental responsibilities with a long-term and broad view to mitigate climate change. It declares its commitment to improving energy efficiency and reducing greenhouse gas emissions, as well as to formulating greenhouse gas reduction plans aligned with the goals of the Paris Agreement and promoting initiatives toward achieving net zero by 2050. The Position on Climate Change also states that Astellas will fulfill its corporate responsibility in adapting to climate change.
Energy Efficiency
In fiscal year 2025, investments of approximately 1.4 billion yen were completed, primarily focused on expanding renewable energy use at each site (e.g., wind power equipment renewal) and implementing energy-saving measures (e.g., upgrading to energy-efficient refrigeration and HVAC systems, and adopting LED lighting).
Renewable Energy Introduction
The use of renewable energy is one of the most effective measures to address climate change. Astellas is working to reduce GHG emissions by installing facilities such as solar and wind power generation and biomass boilers, as well as by purchasing electricity derived from renewable energy sources. Astellas will continue its efforts to expand the use of renewable energy, which will help achieve net zero.

Starting in April 2020, Astellas switched all electricity purchased by its three business sites in Ibaraki Prefecture (Tsukuba business site, Tsukuba Tokodai business site, and Takahagi business site) to an electricity rate plan deemed to be renewable energy. Since FY2025, we have also expanded the use of renewable energy at the Yaizu and Toyama sites (This enabled a reduction of emissions equivalent to about 40,000 tons of GHG emissions in fiscal 2025.)
Environmental considerations for pharmaceutical packaging
In the case of pharmaceutical packaging, certain functions remain essential to ensure the safe storage of products as well as compliance with the provisions stipulated under the Pharmaceutical and Medical Device Act of Japan and the laws and regulations of respective countries. In addition to these functions and requirements, Astellas selects environmentally friendly materials for use in its packaging while engaging in a variety of initiatives including the labeling of materials to promote recycling at the time of disposal.
One initiative is to start using blister sheet biomass plastic made from plant-derived raw material. Blister packaging is eco-friendly packaging using 50% of raw materials from sugarcane-derived polyethylene, a biomass plastic. Blister packaging is required to have a high level of tablet protection and usability, and by using a packaging technology developed over many years, it meets these requirements and can be mass-produced. In fiscal 2021 Astellas started using blister packaging made from plant-derived raw materials for some products in Japan.
Understanding GHG emissions in the supply chain
In addition to emissions directly generated by business activities (Scope 1 and Scope 2) in the Environmental Action Plan concerning climate change, Astellas is also striving to assess emissions produced throughout the entire supply chain (Scope 3). We have also set SBTs for GHG emissions from major categories within Scope 3 and are striving to reduce them. In addition, we encourage support and cooperation with our measures to reduce GHG emissions, including transactions among our production contractors. For details on Scope 3 GHG emissions, please refer to ESG Data.
Scope 1＋2
The reduction rate of Scope 1 and 2 emissions from the base year of fiscal 2015 was 60% in FY2025. This was driven by factors such as the use of renewable energy-derived electricity at major manufacturing and research sites, as well as reductions in CO₂ emissions from company vehicles.
Scope 1 and 2 emissions attributable to the operation of the Takaoka Plant in fiscal year 2025 amounted to 2,513tons. With the cessation of operations, these emissions will be reduced from FY 2026 onward.
The climate change mitigation investments implemented in FY2025—such as the promotion of renewable energy use and energy efficiency measures—resulted in a GHG emissions reduction of 2,348 tons. Astellas will continue to review investment plans, including the introduction of renewable energy, on an ongoing basis.
Since fiscal 2008, Astellas has been striving to reduce GHG emissions associated with the use of our sales fleets. In each region, we are continuously switching over to vehicles with low environmental impact (e.g., hybrid cars, electric vehicles). In Japan and the US, where the rate of introducing hybrid vehicles is high, the volume of GHG emissions relative to the number of vehicles has been reduced more than in other regions.
GHG emissions associated with the use of sales fleets are reported under Scope 1 (fuel use) and Scope 2 (electricity use in electric vehicles).
| Unit | FY2015 | FY2023 | FY2024 | FY2025 | |
|---|---|---|---|---|---|
| Emissions from company vehicle use | t-Co2 | 28,725 | 13,380 | 13,323 | 10,707check_box |
When it cannot be directly measured, CO2 emissions are estimated based on fuel purchase costs, annual average fuel usage by company vehicles or private vehicles (if used in sales activities) and other factors. Figures do not include data from Asia/Oceania region (with partial exception).
GHG emission reduction target
Astellas established Scope 1 and 2 targets aligned with the Paris Agreement’s 1.5°C goal, and Scope 3 targets aligned with the well-below 2°C goal. These targets were approved by the Science Based Targets initiative (SBTi) and publicly announced in January 2023.
Astellas’ GHG emission reduction targets cover the entire Astellas Group, with no exclusions by region or business. The target covers energy-related CO₂ emissions.
Emissions of fluorinated gases from production sites (global) and research sites (Japan) are calculated separately on a CO₂ equivalent basis; in fiscal year 2025, these amounted to 518 t-CO₂e.
The annual average reduction target for Scope 1 and 2 emissions is set at 4.2%, which is aligned with the Paris Agreement’s 1.5°C target. The annual average reduction target for Scope 3 emissions is set at 2.5%, which is aligned with the well-below 2°C target. Both Scope 1+2 and Scope 3 use fiscal year 2015 as the base year. Astellas reviews its GHG emissions reduction targets every five years. The next revision is scheduled to be finalized by January 2028.
Net zero targets
We aim to achieve net zero by 2050 by reducing GHG emissions by 90% from the 2015 baseline and neutralizing the remaining 10% of residual emissions. Neutralization is expected to be achieved through carbon dioxide removal (CDR); however, specific removal methods will be determined in consideration of future technological developments.
Total energy consumption
Global energy usage in FY2025 by the Astellas Group amounted to 450 GWh, for a decrease of 9% (45 GWh) over the previous year. The percentage of total energy consumption accounted for by electricity is high because in each region a large amount of electricity is consumed by the operation of air conditioning equipment.
Astellas strives to reduce its energy consumption, including through the continued implementation of energy-saving measures and the introduction of highly efficient equipment.
For Breakdown of Energy Consumption, please refer to ESG Data
Astellas did not utilize GHG removals in FY2025.
Astellas did not use carbon credits in FY2025. As means of procuring renewable electricity, the Company utilizes power generated from its own solar panels and wind power facilities, as well as electricity products considered renewable energy and off-site corporate PPAs.
Astellas has not introduced an internal carbon price on a company-wide basis in FY2025.
Recognizing that further enhancements to current initiatives will be necessary to achieve greenhouse gas emission reductions beyond 2030, Astellas plans to consider introducing an appropriate level of internal carbon pricing to support investment decisions and cost assessments related to climate change measures.
An assessment of the financial impact on Astellas was conducted for four hazards (flood, wind, wildfire and heat). For flood, wind and wildfire the results are in the form of Average Annual Loss, which is the aggregated, probability-weighted, impact across all the return periods. For heat the results are in the form of Productivity Losses which are based on the days that maximum temperatures exceed >35°C.
Estimated total financial loss from flood, wind, heat and wildfire is ¥3bn in 2050 under a >4°C scenario. Flooding accounts for almost two thirds of total direct loss (¥1.97bn) and 67% of this is from one site, Toyama Technology Center. The potential loss from flooding at Toyama accounts for 44% of direct total loss from all hazards combined. High wind speeds account for just over one third of the total direct loss (¥0.99bn). Loss from building damage accounts for 66% of the total losses. The sites associated with the highest financial impact are located in areas frequently hit by typhoons. Despite heat being one of the most significant climate hazards to Astellas under a >4°C in 2050, the financial impact from the risk is limited (compared to other hazards). This is due to the fact that all of Astellas’ sites have been fitted with adequate HVAC systems that are updated and maintained regularly.
Toyama Technology Center is expected to incur over ¥1.5 billion in losses primarily due to flooding in 2050 under a >4°C scenario. The bar charts below illustrate the top ten sites for total loss across Astellas-owned sites excluding Toyama, indicating that acute wind and flood events significantly impact Astellas-owned sites.
