The ENW Environmental Policy, based on the ENW Charter of Business Conduct, outlines the basic principles and nine specific action guidelines for ENW's environmental conservation activities. Based on this policy, ENW in Japan is actively and continuously developing environmental conservation activities. This policy was revised in December 2024 after the approval of the Growth & Operating Committee, the decision-making body of the business execution division. Under the supervision of the Board of Directors, the Eisai Group has established the Eisai Environment & Safety Committee, which is chaired by the Corporate Officer in charge of Sustainability and General Affairs, to deliberate and decide on important matters related to environmental conservation in accordance with this policy.

Major Environmental Activities
1. Response to climate change
Through scenario analysis such as TCFD, we identify the impacts, risks and opportunities caused by climate change, and by formulating and implementing transition plans, we promote greenhouse gas emission reductions and energy conservation, aiming to achieve the SBT 1.5°C target and RE100 by FY2030, net zero by 2050, and realize business opportunities.
2. Prevention of environmental pollution
We comply with environmental laws and regulations and work to prevent environmental pollution through the proper management of chemical substances.
3. Sustainable water use
We promote sustainable water use by reducing water usage, using it effectively, and managing wastewater quality. We aim to reduce water withdrawal by 7% by FY2030 compared to FY2023.
4. Biodiversity Conservation
Based on the Eisai Biodiversity Guidelines, we implement biodiversity conservation activities in all countries and regions where we conduct business, and contribute to the realization of a society that coexists in harmony with nature.
5. Recycling of resources
We implement appropriate waste management, reduce the amount of waste generated, improve recycling rates, and reduce the amount of waste ultimately disposed of in landfills, and engage in resource recycling. By FY2030, we aim to reduce waste generation by 7% compared to FY2023, while achieving a recycling rate (including sales of recyclable materials) of 50% or more and a final landfill rate of 2% or less.
