Environmental Friendliness Efficiency Indicators
Kokuyo Group designates unique environmental friendliness efficiency indicators as indices to comprehensively evaluate financial performance and impact on the global environment.
These indicators show the extent to which products and services are being offered to society with respect to specific environmental load and correspond to the following four items.
- CO2 emissions
- Final waste disposal
- Usage of chemical substances subject to PRTR regulations
- Water usage
Using fiscal 2000 as the baseline for each indicator, the progress status for each fiscal year can be determined.

Environmental Friendliness Efficiency Indicators

“Chemical substances” indicates the volume of Class 1 PRTR substances handled by reporting sites that are required to report the data under PRTR regulations.
JEPIX
The Japan Environmental Policy Priorities Index (JEPIX) is a method of quantifying the individual amount of different types of environmental loads, such as greenhouse gas emissions and air pollutants, as single indicators called Environmental Impact Points (EIP). The EIP is calculated by multiplying the environmental load of each environmentally harmful chemical by the integrated coefficient, which is calculated from the ratio between Japan’s environmental policy target and the actual amount of emissions (environmental friendliness factor), and then obtaining the sum total of them all.

CO2 Emission Transition

The graph excludes greenhouse gas emissions from sources other than electric power as such emissions were negligible (accounting for less than 0.1% of total emissions).
Electricity-based emission factors are calculated using the basic emission factors of the relevant electrical power companies for each given year
Results for 2020 and later are disclosed based on a market-based approach.
Scope 1 and 2 Emissions
Kokuyo, 20 consolidated subsidiaries (domestic and overseas), 10 affiliates (domestic and overseas)
CO2 emission transitions

Market-based
In line with the GHG Protocol’s Scope 2 Guidance, we take the market-based approach (which reflects supplier-specific emissions factors associated with our energy purchases).
Differences due to changes in emission factors are calculated using the average emission factors of all power sources in 2000 (0.378kg-CO2/kwh).

The unit calorific values of gas, oil, and heat are those values presented in the Greenhouse Gas Emission Calculation and Reporting Manual, Ver. 4.8 (Jan 2022, Ministry of the Environment, Ministry of Economy, Trade and Industry). |

CO2 Emissions from Energy Use | t-CO2 | CO2 emissions from the use of electricity, gas, oil, and heat (see Global Warming Preventive Measures: Respond to the climate crisis) Coefficients based on the Act on Promotion of Global Warming Countermeasures (adjusted emission coefficients for each power company for fiscal 2019 and 2020) were used to calculate the CO2 emissions from power consumption in Japan. For power consumption overseas, we use the local emissions factors listed in IEA Emissions Factors 2022. Values presented in the Greenhouse Gas Emission Calculation and Reporting Manual, Ver. 4.8 (Jan 2022) (Ministry of the Environment, Ministry of Economy, Trade and Industry) were used to calculate CO2 emissions from the use of gas, oil, and heat. The ton/kilo method and the fuel consumption method were both used to calculate the distribution (consigned transportation) CO2 emissions. |
Other Greenhouse Gases | t-CO2e | Emissions of greenhouse gases (CO2, CH4, N2O) related to production activities, (in Japan), but excluding such emissions from energy sources, have been converted to a CO2 basis. Emission coefficient values were taken from the Ministry of the Environment and the Ministry of Economy, Trade and Industry's Greenhouse Gas Emission Calculation and Reporting Manual, Ver. 4.8 (Jan 2022). |
SO2">x, NO2">x | t | Emissions from smoke- and soot-producing facilities at manufacturing plants (in Japan) |
Waste | t | The volume of discharged waste (emissions) is the total amount of waste and valuable substances discharged from business establishments. The recycle volume is the total of the volume of discharged waste (emissions) that has been recycled through material or thermal recycling, and the volume of valuable substances. The final waste volume is the combined total of the recycling residue and the volume of waste directly disposed of in landfills, out of the total volume of discharged waste (solid waste) (see Resource Saving and Recycling: Contribute toward a circular economy). If industrial waste has been calculated by cubic measurement, conversion factors (reference) for converting cubic measurements of industrial waste into weights as stated in a notice released by the Ministry of the Environment (December 27, 2006; Env. Ind. Waste Issue No. 061227006) were used. |
Wastewater | km3 | Wastewater discharged to areas of water for public use and into the sewage system |
COD, BOD | kg | Of plants in Japan, the volume of effluent discharged to areas of water for public use by plants with a legal obligation to measure water quality |
