On July 1st, Toshiba Corporation's Semiconductor Company and Storage Products Company consolidated to form Semiconductor & Storage Products Company.This page describes previous Semiconductor Company's environmental activities.
Environmental Accounting
Semiconductor Company Group engages in environmental accounting that aggregates and analyzes the investment amount and expenses relating to environmental preservation as a tool to promote environmental management.
We calculate the actual economic effects from reduction of costs such as electricity and waste disposal, and we estimate the tangible economic effects from reduction of environmental impact on the air, water, and soil, prevention of potential future risks, and by utilizing data in our environmental management system. We refer to the “Environmental Accounting Guideline 2005” issued by Japan's Ministry of the Environment for classification of the environmental preservation expenses and calculation criteria. The benefits are calculated using quantitative data of environmental impact reduction benefits to deduce monetary value.
Environmental Protection Costs
Environmental protection costs in 2009 amounted to 22 billion yen. Most of the costs were associated with the Group's efforts toward prevention of air, water and soil pollution, reduction of contribution to global warming, recovery and recycling, and research and development. The investment budget for FY 2010 increased by 8.9 billion yen from the previous year. We plan to focus our investments in the near future on efforts to reduce the amount of emissions of chemical substances.

Environmental Protection Benefits
On the other hand, the environmental preservation benefits in FY 2009 were estimated at 7.4 billion yen in total, partly because the amount of reduction of the energy cost due to production fluctuation was around 4 billion yen. The tangible effect figure was negative because the emission amount of chemical substances at some manufacturing plants increased.
| Classification | Content | Benefits |
|---|---|---|
| Actual benefits *1 | Benefits that can be directly converted into monetary value, such as reduced charges for electricity, water, etc. | 7,492 |
| Tangible benefits *2 | Benefits concerning reduction in environmental impacts expressed in monetary value | -469 |
| Risk prevention benefits *3 | The extent to which risks are reduced after the investment compared with before the investment is calculated | 391 |
| Total | 7,414 |
- *1 Total of the monetary value of the reductions in electricity charges, costs of waste disposal, etc. compared with the previous year and the proceeds from sale of items with value
- *2 Monetary values were calculated by giving each substance, calculated in terms of cadmium, a weighting based on environmental standards and ACGIH-TLV (allowable concentration of each substance (Threshold Limit Values) as determined by the American Conference of Governmental Industrial Hygienists) and multiplying the result by the amount of compensation in the case of cadmium pollution. Reduction in environmental impact on atmosphere, water and soil is indicated quantitatively and the environmental impact reduction volumes are compared with the previous year's results, and also reduction of environmental impact is calculated in terms of monetary value to enable comparison of various calculations of environmental impact on the same basis.
- *3 Benefits of investment in environmental structures or double containment such as dikes and double piping, for the purpose of preventing pollution of soil and groundwater, are evaluated as benefits to prevent risks that might otherwise occur in the future. Risk prevention benefits for each capital investment item are calculated according to the following formula:
Risk prevention benefits = Quantity of chemical substances stored × Standard amount (monetary value) required for remediation and restoration × Occurrence coefficient, where the standard amount required for remediation and restoration and the occurrence coefficient are values unique to Toshiba. Risk of occurrence of leakage of chemical substances etc. is evaluated.
