From Fiscal 2024 onward, the Scope 3 boundary has been expanded to cover the entire consolidated group.
(Fiscal 2021 to Fiscal 2023 calculations covered only our replanning business. Please refer to the non-consolidated figures.)
For the calculation of Category 1, the recycled content method (cut-off approach) has been adopted.
Calculation method for greenhouse gas emissions Scope3
| Scope3 classification |
Category details | Calculation method |
|---|---|---|
| Category 1 | Purchased goods and services | Calculated by multiplying the purchase of goods in the Replanning Business and the book value of the building of the replanning property in the fiscal year by the emission factor |
| Category 2 | Capital goods | Calculated by multiplying the increase in property, plant and equipment in the fiscal year by the emission factor |
| Category 3 | Fuel and energy related | Calculated by multiplying the energy consumption calculated for Scope 1 and 2 by the emission factor |
| Category 4 | Transportation and delivery (upstream) | Not applicable |
| Category 5 | Waste generated in operations | Calculated by multiplying the amount of waste generated by the Replanning Business in the fiscal year by the emission factor |
| Category 6 | Business travel | Calculated by multiplying the number of employees involved in the Replanning Business in the fiscal year by the emission factor |
| Category 7 | Employee commuting | Calculated by multiplying the result of multiplying the number of employees involved in the Replanning Business in the fiscal year by the number of business days by the emission factor |
| Category 8 | Leased assets (upstream) | Not applicable |
| Category 9 | Transportation and delivery (downstream) | Not applicable |
| Category 10 | Processing of sold products | Not applicable |
| Category 11 | Use of sold products | Calculated by multiplying the result of multiplying the total floor area of the replanning properties sold during the fiscal year by the remaining useful life by the emission factor |
| Category 12 | End-of-life treatment of sold products | Calculated by multiplying the total floor area of replanning properties sold during the fiscal year by the waste intensity and emissions intensity |
| Category 13 | Leased assets (downstream) | Calculated by multiplying the amount of energy used by tenants of the fixed asset property in the fiscal year by the emission factor |
