Sustainability Data Calculation Report

Eisai Co., Ltd.

Calculation period: April 1, 2025 to March 31, 2026 (If the calculation period is different, details are indicated in the table below)
Calculation target	Scope of calculation	Calculation method/definition of calculation target	Number	*
Greenhouse gas emissions: Scope 1 (CO2 from energy sources)	Eisai Co., Ltd. and domestic and overseas group companies (hereafter referred to as "Global")	・Calculated using the amount of activity multiplied by CO2 emission coefficient. ・The following emission factor is used: Table of standard calorific values and carbon emission factors by energy source (FY2023 Revision, partially updated in March 2026), General Energy Statistics, Agency for Natural Resources and Energy	38,980 t-CO2	☑
Greenhouse gas emissions: Scope 2	Global	・CO2 emissions are calculated on a market-based method. ・The following electricity emission factors are used: Japan: Emission factors by electricity supplier (adjusted emission factors (residual) for calculating greenhouse gas emissions from specific emitters) Overseas: IEA database (IEA Emission Factors 2025 edition) ・The emission coefficients for CO2 emissions from heat (hot water) and cooling (cold water) sources are based on the “List of calculation methods and emission coefficients in the calculation, reporting, and disclosure system.” , Ministry of the Environment, Government of Japan. ・For facilities (offices) where original electricity consumption data, such as utility invoices issued by electricity suppliers, cannot be readily obtained, the following estimation methods are used: 1. Allocate the facility's electricity consumption based on the usage of the entire building; or 2. Estimate the facility's electricity consumption based on the usage of similar facilities. ・For electricity, non-fossil certificates, renewable energy power programs, and renewable energy certificates are used.	4,927 t-CO2	☑
Greenhouse gas emissions: Scope 3 (Category 1)	Global Purchased raw materials, consignments, and supplies	・Calculated by multiplying the purchase price by the JPY conversion exchange rate, dividing the result by 1,000,000, multiplying by the emission factor, and then dividing by the price adjustment factor. ・The following emission factors are used: Ministry of the Environment: "Emission factor database for calculating greenhouse gas emissions and other environmental impacts of organizations throughout the supply chain (Ver.3.6)" AIST Solutions: "IDEA (Ver.3.5.1)" ・A price adjustment based on FY2019 as the reference year is applied. For domestic offices, a price adjustment coefficient based on the Bank of Japan’s Domestic Corporate Goods Price Index is used, while for overseas offices, a price adjustment coefficient based on the IMF's GDP deflator is applied. This adjustment applies to emissions calculated using the Ministry of the Environment’s emission factors.	759,554 t-CO2	☑
Water Withdrawal	Global	・Meter readings or invoice data for tap water, surface water, groundwater, and purchased recycled water are used. ・For research/production/office facilities where it is difficult to obtain original data on raw water withdrawal, the following estimation methods are used: 1. Allocate the facility's water withdrawal based on the usage of the entire building; or 2. Estimate the facility's water withdrawal based on the usage of similar facilities.	3,146 thousand m³	☑
Water discharge	Global	・The baseline figures for sewage and river discharge (such as measurements from drainage flow meters) are used. ・For research/production/office facilities where it is difficult to obtain original data on wastewater volume due to the absence of wastewater monitoring equipment, the amount of wastewater is calculated as the same as the amount of water withdrawal. ・If the amount of sprayed water or evaporation from the cooling tower can be estimated, the estimated value is used.	2,321 thousand m³	☑
Amount of waste generated	Global Total of 29 locations	・The total amount of waste is calculated by combining the amounts of industrial waste and general business waste generated (waste classification is based on each country’s definitions) ・Valuables (those from which the Group still receives income even after offsetting transportation costs) are not included. ・Radioisotope (RI) waste is not included. ・The calculation target covers 29 locations, excluding offices that are not subject to the Company’s waste management controls.	5,484 ton	☑
Number of employees by region	Global	・The number of employees is aggregated across all global companies both as a global total and by region (Japan, Americas, EMEA, China, and EAGS). The definition of regions is the same as that of the reportable segments in the securities report. ・The definition of an employee is the same as that used in the securities report (the number of regular employees as of March 31, 2026, excluding employees seconded from Eisai Co., Ltd. or its consolidated subsidiaries to entities outside the Group but including employees seconded from entities outside the Group to the Consolidated Group).
