2023 Results

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.

1. CO₂ emissions
2. Final waste disposal
3. Usage of chemical substances subject to PRTR regulations
4. 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

• The chemical substances have been calculated according to the volume of chemical substances designated as class 1 under the PRTR Law handled by sites (in Japan) which are required to report data under the PRTR Law.
• The actual values from April to December 2023 have been given for the volume of chemical substances handled in 2023 in response to the revision to the PRTR Law.
• CO₂ (greenhouse gas emissions) from 2019 have been calculated according to the adjusted emission factor for each power company.

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.

Global Warming Preventative Measures

Material Issue: Respond to the Climate Crisis

Attainment of the goal for CO₂ emissions:

The domestic consolidated subsidiaries of KOKUYO K Heart and Heartland have been calculated within the applicable scope.

• 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.

• Market-based (Non-Fossil Fuel Certificate applied)
• 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).

Chemical Substances Subject to PRTR Law

• We made the calculations for the specific class 1 designated chemical substances and the class 1 designated chemical substances under the PRTR Law which was revised in 2021 (came into effect on April 1, 2023). Therefore, the calculation period for the actual values for 2023 of the applicable substances is from April 1 to December 31, 2023.
• The volume of PRTR Law Class I Designated Chemical Substances that were used, handled, released, transferred, disposed, recycled, and consumed by the business establishments (in Japan) subject to notification under the PRTR Law.
• For the calculation methods, see the Ministry of the Environment/Ministry of Economy, Trade and Industry’s PRTR Release Estimation Methods Manual, version 5.0 (March 2023).
• “Volume treated” refers to those PRTR designated substances that were treated on site by incineration, neutralization, breaking down, reactive process, etc.
• “Volume consumed” refers to the volume of substances that were removed from the site by the removal of the products containing or accompanying them or that were modified for disposal by means of chemical reaction with other substances.
