Environmental Initiatives

We are committed to protecting life and the natural world in all its glory

Astellas has embraced the sustainable enhancement of enterprise value as its corporate mission. To fulfill this mission, Astellas seeks to be a chosen and trusted enterprise by all stakeholders, including patients, shareholders, employees, and the global community. The Astellas Charter of Corporate Conduct contains the following principles on Environment, Health and Safety (EHS): “We shall respect our employees’ human rights, individuality, and differences, promote diversity in the workplace, and provide a safe and rewarding work environment,” and “Recognizing that harmony between the global environment and our business activities is a prerequisite to our corporate existence, we shall take proactive measures to conserve the global environment.” These principles require employees to conduct themselves based on high ethical standards in EHS fields, among other areas. In the environment and occupational health and safety pages, Astellas will disclose information on its measures to sustainably enhance enterprise value through EHS.



Astellas has adopted “Turning innovative science into VALUE for patients” as its VISION. In order to continuously achieve sustainable growth, Astellas will need to sensitively grasp changes in the environment and continuously evolve in step with those changes. We will need to address changes in the environment, such as energy trends and climate change, the effective use of resources, and the prevention of pollution. We will also need to implement appropriate management of occupational health and safety in step with changes in modalities, which we will need to handle in many more different ways due to Astellas’ Focus Area approach. In the EHS field, we will be constantly called upon to address changes. Here, Astellas will advance EHS activities based on high ethical standards, in accordance with the Astellas EHS Policy and Guidelines.

Our support of the Task Force on Climate-related Financial Disclosures (TCFD) recommendations was one of our topical initiatives for fiscal 2020. Growing numbers of companies are supporting the TCFD amid increasing demands, mainly from institutional investors, for information disclosure on initiatives addressing environmental issues. Astellas announced its support in December 2020 and began disclosing information in response to TCFD from 2021. Moreover, under the Corporate Strategic Plan (CSP2021) announced in May, we added strategic targets to new initiatives to improve sustainability. The main elements of these strategic targets are the achievement of a greenhouse gas (GHG) emission reduction commitment approved under the Science-Based Targets (SBT) initiative and improved transparency related to disclosure of information about climate change mitigation measures. Reduction of GHG emissions is moving forward as the Environmental Action Plan progresses. In addition to using power derived from renewable energy sources, external factors such as measures to counter the spread of COVID-19 have produced results exceeding targets for 2030. We will continue working toward the 2030 targets this year.
Moreover, it is essential for management to ensure the safety of employees as they engage in corporate business activities. In order to remove hazards that could lead to work-related accidents at an early stage, it is crucial to continuously undertake broad-based risk assessments and develop a sharp eye for assessing hazards. We will continuously implement training and risk mitigation activities in order to prevent work-related accidents in all business areas, including research, production and sales.
