* Refer to the Data on Environmental Impact Resulting from Business Activities for details on the methods used to calculate amounts.
* Total emissions of waste are expressed as a composite of the amount recycled (excluding valuables) and the amount disposed.
* Recycling rate is calculated by dividing the amount recycled (including valuables) by the amount generated (including valuables).
* Total emissions of BOD and COD are calculated by multiplying the average concentration by the amount of wastewater.

* The heat energy conversion factor is calculated in keeping with Greenhouse Gas Emission Calculation - Reporting Manual, which is based on the act on Promotion of Global Warming Countermeasures.
