Methods of Calculating CO2 Emissions in Scope 3

Category Outline Calculation method
1 Purchased goods & services Products purchased in the fiscal year concerned multiplied by the emission intensity for each purchase price. Regarding materials, the purchase price of the main constituent materials in each product (excluding semifinished products) multiplied by the emission intensity.
2 Capital goods The price of equipment and other capital goods acquired in the fiscal year concerned multiplied by the emission intensity for each investment amount.
3 Fuel- and energy-related activities Calculated according to emissions in the extraction, production, and transportation of purchased fuel and fuel used when purchased electricity is generated. Fuel: Each fuel purchased in the fiscal year concerned multiplied by the emission intensity. Electricity: Purchased electricity quantity multiplied by the emission intensity.
4 Upstream transportation & distribution Calculated according to emissions involved in the procurement of purchased products and services and emissions involved in the transportation of manufactured products. Regarding purchased products and services, each of the same items as in Category 1 multiplied by the emission intensity involved in procurement. Regarding manufactured products, expenses involved in shipment multiplied by the emission intensity.
5 Waste generated in operations Regarding waste at manufacturing sites excluding valuables, financial value of the waste multiplied by the emission intensity.
6 Business travel Business travel expenditure is calculated by multiplying expenses involved in employee travel by the domestic employee commuting/business travel expense ratio. Emissions are then calculated by multiplying this business travel expenditure by the emission intensity taking account of the content of business travel.
7 Employee commuting Commuting expenditure is calculated by multiplying expenses involved in employee travel by the domestic employee commuting/business travel expense ratio. Emissions are then calculated by multiplying this commuting expenditure by the emission intensity assumed from the means of commuting.
8 Upstream leased assets Not subject to calculation
9 Downstream transportation & distribution Not subject to calculation
10 Processing of sold products Not subject to calculation
11 Use of sold products Electricity consumed by TDK products (components) multiplied by the lifelong operating time of set items contained in the product, conversion coefficient, and quantity of TDK products (components) sold.
12 End-of-life treatment of sold products Not subject to calculation
13 Downstream leased assets Not subject to calculation
14 Franchises Not subject to calculation
15 Investment Not subject to calculation
