Breakdown of Energy Consumption 
Global energy usage in fiscal 2021 by the Astellas Group amounted to 3,517 terajoules (TJ), for a decrease of 0.2% (8 TJ) 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.
