Environmental Performance Data
Business Activities and Environmental Impact
The SII Group believes that understanding environmental impact properly throughout the product life cycle is the basic practice of environmental activities. The overview of FY 2022 environmental impact is explained below.

*1 The investment for FY 2022 only. In case we judged that the total outlay included any costs other than environmental protection costs, only the proportion deemed to apply to environmental protection was counted.
*2 Includes depreciation expense for FY 2021 or before. (Equipment and facility investment are depreciated over 5 and 10 years, respectively, in equal yearly increments.) In case we judged that the total outlay included any costs other than environmental protection costs, only the proportion deemed to apply to environmental protection was counted.
