The Group’s Environmental Performance

Scope of application

Scope
The Group’s production bases (Domestic: 9 business sites; Overseas: 14 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 the market-based method*.

(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) Energy usage and CO2 emissions data are verified by a third party.

(3) All data was reviewed prior to disclosure.
