Methods for Calculating Performance Data

Methods for Calculating Energy Consumption and GHGs

TypeConversion Coefficients
Calorific valueCOemissions
Electricity3.6 GJ/MWh --tons/MWh
Kerosene36.7 GJ/kiloliter2.49 tons/kiloliter
LPG50.8 GJ/ton3.00 tons/ton
LNG54.6 GJ/ton2.70 tons/ton
City gas45.0 GJ/thousand m³N2.24 tons/thousand m³N
Diesel oil37.7 GJ/kiloliter2.58 tons/kiloliter
Gasoline34.6 GJ/kiloliter2.32 tons/kiloliter
Purchased thermal energy1.36 GJ/GJ0.057 tons/GJ

Beginning with the disclosure of results for fiscal 2023, the amount of power associated with the use of electricity generated by the Company using purchased electricity and renewable energy sources (such as solar and wind) has been converted at a rate of 3.6 MJ per kWh. The amount of CO2 emissions attributed to the use of energy other than electricity is calculated based on the emission coefficient as provided for in the Act on the Promotion of Global Warming Countermeasures prior to its revision in 2023. (Note: Steam used at the Company’s Shenyang Plant is converted using a unit calorific value of 2.8 GJ/ton and CO2 emissions of 0.091 t-CO2/GJ.)
* To calculate the CO2 emissions resulting from electricity usage, Astellas uses CO2 emission coefficients provided by the electric power companies that supply each business facility (market-based method). In the case of Japan, we use the most recent adjusted emission coefficient of each electric power company announced by the Ministry of the Environment and the Ministry of Economy, Trade and Industry. In other regions where individual coefficients cannot be obtained, we use the latest country-specific coefficients provided in IEA Emissions Factors (2023 edition) published by the International Energy Agency (IEA).

Calculation Method for Scope 3 Emissions

CategoriesBasis for calculation and calculation methodEmission source unit
1Purchased goods and services

Based on: Purchase price (millions of yen)

Purchase monetary amount of raw material and consumables (excluding consumption tax) x (emission source unit of each raw material and consumable x 1.05)

NOTE: VAT was not taken into account in GHG calculation for non-Japan Affiliates.

Target: (Global) production facilities receiving deliveries of raw materials
Emission source unit:
・Source: The Ministry of the Environment's database*[5]; emission source units based on the industry-related table
Emission source unit on monetary basis for each raw material (purchaser price basis) (=t-CO2 equivalent / 2005 consumption tax inclusive amount)
・Foreign exchange: Foreign currencies are converted to yen using the annual average of monthly TTM rates.
2Capital goods

Based on: Capital expenditures, software purchases (millions of yen)

Facility investment amount (consolidated)* x emission source unit per price of capital goods

Software purchase amount (consolidated) x emission source unit per price of capital goods
