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 Emissions from the use of leased equipment are reported under Scope 1 and 2.
9 Downstream transportation & distribution TDK is a midstream company, a manufacturer of electronic components, so this is not applicable.
10 Processing of sold products Not applicable because the emissions associated with the processing of our products by our customers are small.
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 TDK is a midstream company, a manufacturer of electronic components, so this is not applicable.
13 Downstream leased assets Not applicable because there is no applicable business activity.
14 Franchises Not applicable as there are no franchise stores.
15 Investment Not applicable as there is no applicable investment.

Environmental Accounting（Japan）

TDK has historically monitored both the cost of its environmental protection efforts and the load its activities place on the environment. In fiscal 2002, to clarify the relationship between load and cost, and to promote more effective environmental measures, TDK introduced environmental accounting for all of its facilities in Japan.

A summary of fiscal 2023 results is given below.

  • *The investment amount for the fiscal year is the amount paid in fiscal 2023.
  • *Equipment depreciation costs（as defined by law）are included as part of environmental conservation, maintenance, and management costs, but personnel costs are not included as they are determined by the number of employees in a given fiscal year.
  • *Only actual benefits are included. Hypothetical impacts（risk-avoidance impact or presumed impact）are not included.

Summary of Fiscal 2023

・Environment-related capital investment increased in the previous year from ¥429 million to ¥1,596 million.
・Environmental conservation, maintenance and management costs increased in the previous year from ¥1,613 million to ¥2,788 million.
・The economic benefits of environmental conservation activities increased from ¥1,664 million to ¥1,820 million, mainly due to an increase in sales price of valuable materials sold.
