Environmental Performance Data

Environmental Performance of Domestic Business Sites

Scope of application

Scope
Eight domestic sites ( GS Yuasa International Ltd. (Kyoto, Osadano, Gunma and Ritto Plants), GS Yuasa Energy Co., Ltd., GS Yuasa Ibaraki Co., Ltd., GS Yuasa Moldings Co., Ltd. and GS Yuasa Azumino Co., Ltd.)
Greenhouse gas emissions related to Scope 2

(1) Scope 2 emissions refer to CO2 emissions calculated based on market standards*.

(2) Scope 2 emissions are calculated using the annual coefficient for each power company announced in accordance with the Act on Promotion of Global Warming Countermeasures. However, the conversion factor for power derived from renewable energy is set as zero.

Remarks

(1) Environmental performance related to transportation refers to actual values for GS Yuasa International Ltd.

(2) The figures for past performance are also calculated using the revised criteria due to the scope of application having been revised in fiscal 2022. See here for more details on this revision.

(3) All data was reviewed prior to disclosed.

A method of calculating Scope 2 emissions based on the contents of the contract for purchased electricity.

Production of Specific Class I Designated Chemical Substances

The Group’s Environmental Performance

Scope of application

Scope
The Group’s production bases (Domestic: 8 business sites; Overseas: 16 business sites)
Scope of application regarding greenhouse gas emission

(1) The scope of application of Scopes 1 and 2 is the same as the above scope of application.

(2) Regarding the scope of application of Scope 3, the scope of calculation is clearly indicated for each category.

Greenhouse gas emissions related to Scope 2

(1) Scope 2 emissions show the CO2 emissions calculated using the methods of market standards*.

(2) The CO2 conversion factor in the calculation of CO2 emissions associated with power usage uses the following published values. However, the conversion factor for electricity derived from renewable energy is set to zero.
Japan: Annual coefficient for each power company announced in accordance with the Act on Promotion of Global Warming Countermeasures
Outside of Japan: Annual coefficients announced in “Emissions Factors,” a publication of the International Energy Agency (IEA).

Remarks

(1) Regarding greenhouse gases other than CO2 are excluded from calculation because their relationship to the Group’s business activities is negligible and due to extremely low emissions.

(2) The figures for past performance are also calculated using the revised criteria due to the scope of application having been revised in fiscal 2022. See here for more details on this revision.

(3) All data was reviewed prior to disclosed.
