*1 Scope 1: MITSUBA Group's direct emissions of greenhouse gases (combustion of fuel), calculated using the GHG Protocol emission factor. Data will be changed to the scope of consolidated group from FY 2021.

*2 Scope 2:Indirect emissions associated from the use of electricity supplied by other companies, calculated using theCO2 emission coefficient of each electric power company or the IEA (International Energy Agency) coefficient of each country. Data will be changed to the scope of consolidated group from FY 2021.

*3 Scope 3:Other indirect emissions covering the company's upstream and downstream processes, excluding Scope 1 and Scope 2.
The calculation method for each category is as follows.

• Category 1: Calculated by multiplying the procurement amount of the Group’s raw materials, standard parts, and processed parts by the coefficient in the "Basic Guidelines for Calculating Greenhouse Gas Emissions throughout the Supply Chain.“
• Category 2: Calculated by multiplying the Group's total investment in facilities, etc. by the coefficient in the "Basic Guidelines for Calculating Greenhouse Gas Emissions throughout the Supply Chain.
• Category 3: Calculated by multiplying the Group’s electric power consumption by the coefficient in the "Basic Guidelines for Calculating Greenhouse Gas Emissions throughout the Supply Chain.
• Category 4: Calculated by multiplying the shipping weight and transport distance for Group’s procurement logistics, production logistics, and sales logistics by the GHG Protocol coefficient.
• Category 5: Calculated by multiplying the amount of waste generated by the Group by the coefficient in the "Basic Guidelines for Calculating Greenhouse Gas Emissions throughout the Supply Chain.
• Category 6: Calculated by multiplying the number of Group’s employees by the coefficient in the "Basic Guidelines for Calculating Greenhouse Gas Emissions throughout the Supply Chain.
• Category 7: Calculated by multiplying the number of Group’s employees by the coefficient in the "Basic Guidelines for Calculating Greenhouse Gas Emissions throughout the Supply Chain.
• Category 11: Calculated by using Japan Automobile Parts Industries Association LCI data calculation tool (use stage).

*4 As a result of measurement, only trace amounts of emissions were confirmed, so they are not counted.
*5 Scope: Reporting will be changed to the scope of consolidated group from FY 2021.
*6 Includes waste recycled and reused. Reporting will be changed to the scope of consolidated group from FY 2024.
*7 Scope: MITSUBA and domestic manufacturing group companies
*8 Scope: MITSUBA and domestic and overseas manufacturing group companies
