How is the ECO value calculated?
 The 11 categories covered in “Green-Ink” Accounting cannot simply be added together, because they are expressed in different units. Therefore, “Green-Ink” Accounting (ECO) is calculated by averaging individual ECOs, which are obtained by multiplying the percentage improvement in each category by the weighted coefficient. Improvements are represented by a positive ECO value and degradations by a negative ECO value.
The weighted coefficient is obtained by using a weight (from one to five) assigned by five researchers, Takara Shuzo’s five environmental staff and the results of an Internet poll taken by 137 people, evaluating the level of importance for each category regarding Takara Shuzo’s involvement in reducing its environmental impact.

| The “Green-Ink” Accounting indicator for fiscal year 2006 shows -1 ECO |
| To achieve a Å{(plus) 4 ECO, the target for fiscal 2007, improvement of production indicators will be necessary. |
|
In “Green-Ink” Accounting for fiscal 2006, all production-related indicators showed negative results due to a production increase of 5.3% from the base year fiscal 2004 and a deterioration in production efficiency as the composition ratio of products requiring a lot of energy to produce and generating a great amount of waste rose, in addition to the influence of frequent production of small lots to improve the freshness of our products. This was, however, offset by positive ECO values recorded in the distribution through cutting of CO2 emissions and introduction of low-emission vehicles, as well as by various social contribution activities. As a result “Green-Ink” Accounting indicator showed -1 ECO.
