The Environment

Astellas’ Charter of Corporate Conduct states that, “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.” For Astellas to continue to grow sustainably, we need to be conscious of the issues affecting our local environment and ensure that factors such as energy efficiency, climate change, environmental pollution and waste disposal are central to our corporate activities. We will continue to improve and contribute to establishing a sustainable society while sensitively monitoring changes in business and social environments.
Environmental initiatives and information transparency
Astellas is committed to information transparency regarding our company responses to factors relating to the environment.

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 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.
Message from Astellas’ Chief Strategy Officer
Astellas contributes to the sustainability of society through its business activities. One of the strategic goals of the Corporate Strategic Plan 2021 (CSP2021) is to “Deepen our engagement in sustainability,” and as one of the challenges, we are strengthening our environmental initiatives, including those regarding climate change.
As part of our climate change initiatives, Astellas announced a 2030 target for the reduction of greenhouse gas Scope 1+2 emissions (direct and indirect emissions associated with its own operations) in line with the Paris Agreement’s 1.5°C goal in 2023, as well as a policy to aim for Net Zero by 2050. In fiscal 2024, we introduced solar power generation equipment at the Kerry Plant and the Shenyang Plant, and started using off-site solar power at the Yaizu Technology Center. We set greenhouse gas emission targets annually in line with our 2030 targets approved by the Science Based Targets initiative (SBTi), and our Scope 1+2 emission reductions in fiscal 2024 was on track for achieving our targets. Individual initiatives have also been recognized externally. In 2024, amongst many accolades that they received, Astellas Kerry Plant was awarded the “Sustainability Team of the year” at the Irish Climate Change Leadership awards.
On the other hand, we acknowledge the challenges we face with regard to Scope 3, which is the largest source of greenhouse gas emissions for Astellas. In fiscal 2024, we held a business partner summit and I urged our partners to work together to achieve high transparency on environmental impact. As a result, we were able to confirm that most of the companies that participated in the summit recognized Astellas’ environmental initiatives. Going forward, we will promote efforts to obtain primary data.
The sustainability disclosure, including environmental performance data, is in a transition period from voluntary disclosure to statutory disclosure. Astellas will continue to commit to a high level of transparency.
