| Category 14 | Franchises | The franchise formula is not used. |
| Category 15 | Investments | Calculated by multiplying the emissions from investment destinations (equity method affiliates and companies which hold specific annual stocks and constructive stocks, etc.) by the equity method ratio or the shareholding ratio. |
Third-party verification
In order to ensure the reliability of its environmental data reporting, in fiscal 2011 Casio began requesting third-party verification.
Casio commissioned SGS Japan Co., Ltd. to conduct the audit of environmental data in fiscal 2023. The audit covered greenhouse gas emissions (Scope 1, Scope 2, and Category 1 and 11 of Scope 3), water intake, waste, variable waste, and emissions of atmospheric pollutants (NOx, SOx and dust). Of the sites audited by SGS, on-site surveys were conducted at the headquarters of Casio Computer Co., Ltd., and the headquarters of Yamagata Casio Co., Ltd.
