Being prepared for emergency situations caused by an accident or natural disaster can help to prevent an environmental catastrophe and minimize damage. Accordingly, we have developed specific measures and procedures for these situations. Moreover, we conduct regular education sessions and training drills, and reconfirm and test the validity of our procedures, communication networks and the division of roles focusing on risks that are recognized as a high priority. In this manner, we continue to work diligently to reduce environmental risk.

In particular, the discharge of harmful substances could lead to the pollution of rivers as well as cause problems at public sewage treatment plants. This in turn could have a grave impact on regional communities. In preparation for accidents and emergency situations, we are systematically implementing measures for the prevention of environmental pollution, including the installation of backup equipment, while working to reduce the risk of pollution. In addition, to avoid accidents and other problems, we are bolstering efforts to optimize the operation and management of wastewater treatment systems, and monitor and measure the quality of water draining out of our plants to confirm compliance with relevant effluent standards. 

There was no incident in which Astellas exceeded the upper limit of agreed values specified in a pollution prevention agreement with the local government. Over the past five years, there were two incidents as below. Astellas reported these incidents to the local government and implemented response measures based on its instructions.

Climate change measures

Mitigating and adapting to the threat posed by climate change requires active involvement by national governments, local governments, corporations, citizens, and others. Astellas recognizes that climate change will become a constraint on conducting sustained corporate activity and considers it an important management issue to address.


Astellas has made a long-term commitment to taking measures against climate change and decided to aim for achieving a 90% reduction in GHG emissions and a 10% neutralization of residual emissions to achieve Net Zero by 2050, based on 2015, for Scope 1 and 2 and Scope 3, respectively. In addition, the Science Based Targets (SBT) initiative approved Astellas’ GHG emissions reduction targets through 2030.


To address climate change as a management issue, we have adopted as targets, the 1.5℃ (Scope 1 and 2) and well-below 2℃ (Scope 3) targets of the Paris Climate Agreement.

In order to reduce GHG emissions, Astellas must implement management practices that involve the entire Astellas organization from a medium-term perspective. Astellas’ manufacturing plants, research centers, sales and marketing divisions, and offices are implementing a variety of initiatives with the aim of mitigating climate change.

Regarding tangible elements, efforts to improve facilities, which include the introduction of high-efficiency equipment and the conversion to alternative fuels, are expected to make a significant contribution to reducing the level of GHG emissions generated by energy sources. Regarding intangible aspects, employees’ participation in energy saving through improvements of daily work is also important. To this end, each facility adopts a two-pronged approach, comprising measures related to both tangible and intangible elements.

In fiscal 2024, Astellas completed approximately 2,200 million yen in investments with a focus on the promotion of renewable energy use at each facility (including the installation of solar panels) and energy-saving measures (such as upgrading to air conditioning-related energy-saving equipment and introducing LED lighting), resulting in a reduction of GHG emissions of 2,905 tons.

Astellas will keep on conducting continuous reviews of investment plans related to matters such as renewable energy.

At Astellas’ research and production bases, we use boilers fueled by city gas, LPG and LNG (liquefied natural gas), all of which generate low GHG emissions during combustion. These boilers not only contribute to reducing GHG emissions, but also to reducing SOx emissions, another air pollutant.

Knowing exactly how much energy we use is useful for the formulation of new strategies. We have introduced energy monitoring systems that can visually monitor energy usage at our facilities.

The use of renewable energy is one of the most effective climate change countermeasures. Astellas is introducing photovoltaic panels and wind power generation, and equipment such as biomass boilers. Astellas is also purchasing electricity derived from renewable energy sources to reduce GHG emissions. We will continue to strive for expanding the use of renewable energies to help achieve Net Zero.

* From the disclosure of fiscal 2022 results, the amount of energy consumed by the use of purchased electricity and electricity generated internally using renewable energy sources (solar power, wind power, etc.) is converted at 3.6 MJ per 1 kWh. 

Renewable Energy Consumption

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 100% hydroelectric (*). (This enabled a reduction of emissions equivalent to about 26,000 tons of GHG emissions in fiscal 2024.)

Moreover, we are also moving ahead on switching to electricity generated by renewable energy sources in areas outside of Japan. Looking ahead, Astellas will continue to explore opportunities for using renewable energy, and it will also consider formulating targets for the use of renewable energy.

Sustainable biodiversity initiatives

Astellas is thankful for the benefits brought about by biological diversity and understands all of its business activities have an impact on ecosystems. We will make a positive contribution to the preservation of biodiversity by working to lessen that impact. Furthermore, we actively contribute to the creation of a society that coexists with the natural world, enabling the preservation of biodiversity and the sustainable use healthy ecosystems. Astellas endorses the Declaration of Biodiversity by Keidanren (Japan Business Federation) and makes donations to the Keidanren Nature Conservation Fund. 

  • We will endeavor to lessen our overall environmental impact on biodiversity by working to implement Climate Change Mitigation Measures, minimize environmental pollution, and promote resource recycling.
  • We will endeavor to develop technologies that lessen the impact on ecosystems by lowering the burden we place on the environment and using as few natural resources as possible.
  • We will endeavor to handle genetic resources in accordance with international standards and the regulations of producing nations.
  • We will endeavor to broaden our efforts to preserve biodiversity with the aim of creating a sustainable society that coexists in harmony with nature. To this end, we will promote discussion within society and among affected parties, while reaching across national and geographical borders.
  • We will endeavor to foster a corporate culture that will always act with respect for biodiversity and in a manner that is harmonious with our business activities, grateful for the benefits obtained from healthy ecosystems.
Schematic illustrates a strategy tied to Astellas’ focus on building a sustainable society.

Astellas assesses three main factors that are causing the deterioration of biodiversity: environmental pollution, resource consumption, and climate change. We have created a Biodiversity Index to evaluate the impact of our business activities on biodiversity.

The environmental burden for each sub-category in the assessment fiscal year is divided by the corresponding burden in the base-year and then multiplied by the weight to derive the “biodiversity burden index.” The “biodiversity index” is calculated by dividing Astellas’ consolidated revenue in the assessment fiscal year by the total of all the biodiversity burden index figures. Improvement can be determined by comparing this index to the base year.

Chart illustrates a strategy tied to Astellas’ focus on building a sustainable society.

Astellas recognizes that since the use of sustainable resources is essential for continuing its business activities, it must play an active role in the creation of a recycling-oriented society. We have established an Environmental Action Plan and are moving forward with steps to effectively use water resources and recycle waste materials (reuse, recycling, and use of all thermal energy) as initiatives contributing to a recycling-oriented society.

Environmental Action Plan (Measures for the Conservation of Resources)

Improve water resource productivity by around 20% of the fiscal 2016 result by the end of fiscal 2025.

Applicable areas: Research and production sites in Japan and overseas 

Indicator: Revenue (billions of yen) /Volume of water resource withdrawn (thousand m³) 

Effective Use of Water Resource

The effective use of water resources serves as a useful indicator for gauging society’s impact on biodiversity. Astellas assesses the relationship between water resources and economic activity using a water resource productivity index and has been striving to improve this index. Water resource productivity for fiscal 2023 improved significantly by 65% compared with the base year of fiscal 2016.

Recycling of Water and Reducing Water Consumption

Astellas’ operations use only water drawn from service water, industrial water and ground water. Water used in work operations is treated in accordance with wastewater discharging standards and returned to an aquatic environment. In addition, Astellas is continuously working to reduce water consumption while minimizing process wastewater. 

Risk Assessments

Water is indispensable for Astellas’ research and production activities. Each business site obtains necessary government approval to use water, and wastewater is discharged after being treated to satisfy wastewater discharging standards.

Moreover, Astellas uses Aqueduct provided by World Resources Institute to analyze water risks specific to the operating regions where its plants and other facilities are located

The Astellas Group on a global basis does not currently withdraw water from water bodies in areas concerned with water resource depletion. As water risks may emerge in the future because of climate change, we are conducting risk analysis and taking steps to minimize our dependence on such resources, and also regard this as an effective means of ensuring business continuity

Environmental Action Plan (waste management)

Improve waste generated per unit of revenue by around 10% of fiscal 2016 result by the end of fiscal 2025.

Applicable areas: Research and production sites in Japan and overseas

Indicator: Volume of waste generated (tons)/Revenue (billions of yen

Waste Management 

Waste Management in the Value Chain

In waste management, it is also important to prevent environmental pollution being caused by hazardous waste generated by research centers and manufacturing plants and the illegal disposal of that waste. As a means of prevention, we first examine appropriate methods of waste disposal and then conduct regular on-site assessment that waste treatment contractors are using appropriate waste treatment methods.

Handling status of High-Concentrate PCB-contaminated Waste Storage

We have been systematically conducting detoxification of any high-concentrate PCB-contaminated equipment that is stored by Astellas. All PCB waste was treated during fiscal 2023.

A hand touches a globe, showing how Astellas promotes activities to prevent global environmental pollution.

Initiatives for Preventing Pollution

Astellas promotes activities to prevent global environmental pollution. For major environmental management indicators for air and water quality, we have set and manage stricter voluntary control values than the values stipulated by laws and regulations and agreed values. In addition, we are promoting voluntary activities to reduce atmospheric emissions of chemical substances.

Reduction of VOC Emissions 

Astellas sets voluntary numerical targets for reducing the amount of volatile organic compounds (VOCs) that are emitted accompanying the use of solvents in production and research activities and makes efforts to reduce emissions. Moreover, as a measure to prevent environmental pollution by chemical substances as well as occupational illnesses, we are taking steps to minimize the impact of our business operations on our employees, local communities, and the environment, such as development of new manufacturing processes that do not use highly hazardous chemical substances.

Reduction of NOx Emissions

To reduce the emission of NOx into the atmosphere, Astellas has installed boilers that use gaseous fuels (city gas, LNG, and LPG). The NOx emissions from all business facilities in Japan are as shown in the table below. The NOx emissions from non-Japanese production facilities in fiscal 2024 amounted to 3 tons.

Astellas does not use any equipment that runs on fuel oil, which is a major source of SOx (sulfur oxide) emission.

Environmental impact of products and countermeasures

Astellas does not handle or sell any product that uses hydrofluorocarbons (HFCs) as a filler agent.

Astellas uses plastics in various products and recognizes that handling plastic waste generated in its business activities is an environmental issue. We endeavor to recycle plastic resources. In Japan, a law was enforced in April 2022 to promote the recycling of resources related to plastic. The amount of plastic waste generated in Japan in fiscal 2024 was 244 tons. Astellas is working to limit the amount of plastic waste it generates within Japan to under 250 tons by limiting the use of plastic resources and improving recycling rates.
