Breakdown of Energy Consumption

Breakdown of Energy Consumption 

Global energy usage in fiscal 2024 by the Astellas Group amounted to 496 GWh, for a decrease of 11% (62 GWh) over the previous year. The percentage of total energy consumption accounted for by electricity is high because in each region a large amount of electricity is consumed by the operation of air conditioning equipment.
Astellas strives to reduce its energy consumption, including through the continued implementation of energy-saving measures and the introduction of highly efficient equipment.
