| Category | Investments | Cost | Principal activities | |
|---|---|---|---|---|
| Costs within the production sites | Pollution prevention costs | 48 | 2,160 | Operating cost of environmental facilities, measures to prevent emissions of toxic chemical substances |
| Global environmental conservation costs | 8 | 67 | Cost of energy conservation activities | |
| Resource recycling costs | 3 | 474 | Recycling costs and waste processing costs | |
| Total*2 | 60 | 2,701 | ||
| Upstream and downstream costs | 0 | 86 | Recycling and reuse of packaging materials, improvement of container packaging | |
| Administrative costs | 151 | 166 | ISO 14001, environmental measurements, environmental education | |
| Research and development costs | 0 | 108 | Development of environmentally friendly products | |
| Social activity costs | 0 | 0 | Afforestation, beautification, provision of environmental information to host community residents | |

Environmental damage costs are included in pollution prevention costs.

Due to rounding, totals may not necessarily agree with the sum of the individual figures.
Environmental conservation cost calculation criteria
- Depreciation: Straight-line method
- Standard for allocating costs: In principle, 100% of costs are allocated to individual environmental conservation items. However, a portion of costs is allocated on a pro-rata basis.

Standard for calculating environmental conservation effects
- Effects are calculated in simple comparison with the total environmental load of the previous fiscal year and are not adjusted for production volume.
Standard for calculating economic effects (benefits) of environmental conservation measures.
- Although material effects such as income from recycling are known, benefits are deducted from environmental conservation costs.
