(2) Wastewater
- Wastewater calculations include actual amounts at sites that measure wastewater, and, for sites that do not measure wastewater, their amount of water intake.
- At sites with special facilities that fall under the Water Pollution Prevention Act and/or the Sewer Act, water quality surveys are conducted based on applicable laws, and confirmation is made that emissions are below regulatory limits. Since fiscal 2014, the applicable facilities have not been operating.
- In the case of discharge into public sewer systems, figures are shown if voluntary measurements are taken.
(3) Air pollutants
- Calculated at sites that have smoke generating facilities based on the concentration measurements and gas emissions at each facility.
- Yamagata Casio, Hamura R&D Center, Casio (Thailand) Co., Ltd., and Casio Electronics (Shaoguan) are included in tabulation of results.
- Concentrations of dust emissions, NOx, and SOx, which must be managed by law, are measured at target sites, to confirm that they are below regulation levels.
- The following substances are not used at any Casio site: dichloromethane, trichlorethylene, tetrachlorethylene, chloroform, vinyl chloride monomer, 1,3-butadiene, benzene, acrylonitrile, 1,2-dichloroethane, formaldehyde, trinickel disulfide, nickel nitrate, and acetaldehyde.
(4) PRTR

- Calculated for VOC outputs to air subject to a follow-up survey of achievements related to the four electrical and electronic industry associations’ control of VOC emissions whose annual amount handled is 0.05 tons or more at each site.
(5) Waste
- Waste is tabulated as the total amount of industrial waste generated when product is transferred from a Casio site to the processor, general waste derived from sites, and the quantity of valuable wastes.
- Sites for which it is difficult to monitor waste generation due, for example, to an office lease agreement, are not included in the scope of calculation.
(6) Base year figures
- For the evaluation of greenhouse gases and energy conservation, emissions and usage of divested businesses are excluded from data in and after the base year in accordance with the GHG Protocol.
- For sites that were included in the scope in and after the base year due to acquisition, etc., historical data on emissions and use is only added to historical data for fiscal years in and after the base year when it is available in accordance with the GHG Protocol, which is the international standard.
4. Scope 3 calculation methods
Category 1 | Purchased goods and services | Calculated by multiplying the amount of activity by the unit. Amount of activity: Amount of consumables, raw materials, tap water, industrial water, advertising expenses and salaries of temporary staff. Unit: Emissions unit of the purchased amount of each item of the amount of activity (Source: Emission factor database for calculating organizational GHG emissions throughout the supply chain version 3.2 issued by Japan’s Ministry of Environment and LCI database IDEA version 2.1.3.)The amount of activity was carefully reviewed and emissions were recalculated retroactively for past fiscal years accordingly. |
Category 2 | Capital goods | Calculated by multiplying the amount of activity by the unit. Amount of activity: Amount of capital investment by all consolidated subsidiaries. Unit: Emissions unit corresponding to the amount of capital investment.(Source: Emission factor database for calculating organizational GHG emissions throughout the supply chain version 3.2 issued by Japan’s Ministry of Environment) |
Category 3 | Fuel-and-energy-related activities (not included in Scope 1 or 2) | Calculated by multiplying the amount of activity by the unit.

Category 9 | Downstream transportation and distribution | Transportation to retailers from the distribution hubs of regular sales companies is outside the scope of Casio's expense payment. Since this is difficult to ascertain and the CO2 emissions are deemed to be fairly small compared to Category 4 upstream transportation and distribution, it is not included in calculations. |
Category 10 | Processing of sold products | Although one of our group companies provides name printing and other services, emissions of CO2 and other substances from this business activity is included in Scopes 1 and 2. |
Category 11 | Use of sold products | Calculated by multiplying the amount of activity by the unit for each product model sold and the country of sale during the relevant fiscal year. These are then added together to calculate the total. Amount of activity: Power consumption, lifetime use period, and sales volume by product model. The lifetime use period is calculated using industry standards, if any, or assuming a five-year product life if not specified. Unit: Emissions unit of electricity use (Source: IEA country-specific emission factors. If country-specific emission factors are not available, the global average factor is applied.) |
Category 12 | End of life treatment of sold products | The emissions from each material used in products sold during the fiscal year are used as the amount of activity, and the value is calculated by multiplying by the unit for each material. These are then added together to calculate the total. Amount of activity: Amount of each material used in the product itself and in the container packaging materials. Unit: Emissions unit of each type of material (Source: Emission factor database for calculating organizational GHG emissions throughout the supply chain version 3.2 issued by Japan’s Ministry of Environment) |
Category 13 | Downstream leased assets | In cases when relevant leased assets exist, Casio inquires with the users each asset (building) about the amount of CO₂ emissions, and uses the data they provide to calculate the total amount of emissions. |
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 2022. The audit covered greenhouse gas emissions (Scope 1, 2 and Categories 1 and 11 of Scope 3), water intake, waste (including variable waste), and emissions of atmospheric pollutants (NOx, SOx and dust). Of the sites covered by SGS, on-site surveys were conducted at the Hachioji R&D Center and Casio Business Service Co., Ltd. (Kofu).
