Calculation Method

Classification Summary Scope of coverage Calculation Method
Scope 1 Own direct emissions Manufacturing sites and main offices
(25 sites in Japan + 57 sites overseas, including 5 offices)		 Direct energy-derived CO₂ emissions from corporate activities, such as fuel combustion in factories. emission factors based on the Law Concerning the Promotion of the Measures to Cope with Global Warming are used.
Scope 2 Own indirect emissions Manufacturing sites and main offices
(25 sites in Japan + 57 sites overseas, including 5 offices)		 Indirect CO₂ emissions associated with energy use in corporate activities, such as electric energy use, using the GHG Protocol's market-based approach. For Japan, adjusted emission factors by electric utility are used, based on the Law Concerning the Promotion of the Measures to Cope with Global Warming. For other than Japan, emissions intensity by electric utility or the latest emissions intensity in each region, or emissions intensity from IEA Emissions Factors if these are not available.
Scope 3 Category 1 Goods and services purchased TDK consolidated targets Based on the GHG Protocol, emission intensity is calculated by multiplying the purchase amount of each item purchased in the relevant fiscal year by its emission intensity. For materials, emissions intensity is calculated by multiplying the purchase amount of the main constituent materials of each product by the emissions intensity. Primary data from some suppliers are also used in the calculation. For emissions intensity, please refer to the 3EID Global Expansion Data Book on Environmental Impact Intensity Based on the Input-Output Table.
Category 2 Capital goods TDK consolidated targets Based on the GHG Protocol, emission intensity per unit of value is calculated by multiplying capital goods such as equipment acquired in the relevant year by emission intensity per unit of value. For emissions intensity, refer to the Data Book on Environmental Impact Intensity Based on the Input-Output Table (3EID Global Extension).
Category 3 Fuel and energy-related activities Manufacturing sites and main offices
(25 sites in Japan + 57 sites overseas, including 5 offices)		 Based on the GHG Protocol, emissions intensity is calculated by multiplying purchased fuel and electricity by emissions intensity. For emissions intensity, refer to the emissions intensity database for calculating GHG emissions of organizations through their supply chain by IDEA and the Ministry of the Environment of Japan. For data before fiscal 2023, the amount of activity is based on the purchase amount.
Category 4 Transportation and distribution (upstream) TDK consolidated targets Based on the GHG Protocol, emissions from the procurement of purchased products and services and emissions from the transportation of manufactured products are calculated. Emissions from purchased products and services are calculated by multiplying the purchase price by the emissions intensity of procurement. Emissions from manufactured products are calculated by multiplying the amount of transportation and, in part, the transportation cost by the emission intensity. For emissions intensity of purchased products and services, refer to the data book of environmental impact intensity based on the input-output table (3EID Global Extension), and for emissions intensity of transportation of manufactured products, refer to the transportation cost intensity using IDEA or supplier's primary data.
Category 5 Waste generated from operations Manufacturing sites and main offices
(25 sites in Japan + 57 sites overseas, including 5 offices)		 Based on the GHG Protocol, emission intensity is calculated by multiplying the amount of waste from manufacturing sites by the emission intensity. For emission intensity, refer to the emission intensity database for calculating GHG emissions of organizations through their supply chains, which is provided by IDEA and the Ministry of the Environment of Japan. Waste transport is accounted for in Category 1. For data prior to fiscal 2023, the amount of activity is based on the cost of waste disposal.
Category 6 Business trip TDK consolidated targets Based on the GHG Protocol, the estimated business trip cost is multiplied by the emission intensity based on the means of transportation. For emissions intensity, refer to the data book on environmental impact intensity based on the input-output table (3EID Global Extension).
Category 7 Employee commuting TDK consolidated targets Based on the GHG Protocol, the estimated commuting cost is multiplied by the emission intensity based on the commuting method. For emissions intensity, refer to the 3EID data book on emissions intensity based on the input-output table.
Category 8 Leased assets (upstream) Use of leased equipment is reported as Scope 1 and 2 emissions.
Category 9 Transportation and distribution (downstream) Not applicable as the Company is an electronic component manufacturer.
Category 10 Processing of sold products Not applicable because the emissions associated with the processing of our products by our customers are small and diverse, making the estimate unreasonable.
Category 11 Use of products sold TDK major product lines Based on the GHG Protocol, the power consumption loss generated during the use of TDK products is calculated by multiplying the field of installed set products, lifetime operating hours of installed set products, and emissions intensity by the sales volume. Lifetime operating hours refer to JEITA's guidance on the calculation of GHG emission reduction contribution of electronic components, and emissions intensity refers to IEA Emissions Factors.
Category 12 Disposal of sold products Not applicable as the Company is an electronic component manufacturer.
Category 13 Leased assets (downstream) Not applicable because there is no applicable business activity.
Category 14 Franchise Not applicable because there are no franchise stores.
Category 15 Investment TDK consolidated equity-method affiliates
(Excluding companies that do not disclose emissions)		 Calculated based on the GHG Protocol by multiplying the emissions of companies in which the company has acquired shares by the shareholding ratio.

Environmental Accounting (Japan)

TDK has traditionally monitored its environmental conservation costs and environmental impact, but in fiscal 2002, TDK introduced environmental accounting for its business sites in Japan in order to clarify the relationship between the two and promote more effective environmental measures.

A summary of the aggregate results for fiscal 2024 is as follows.

  • ※The investment amount for the year in question is the amount payable in fiscal 2024.
  • ※The environmental preservation and maintenance expenses for the relevant fiscal year include depreciation (legal) of equipment, and personnel expenses are not included because they are determined based on the number of employees in the relevant fiscal year.
  • ※The effects covered are substantive effects only and do not include presumptive effects (risk aversion and deemed effects).

Aggregate results for fiscal 2024

・Environmental capital expenditures increased to 1,775 million yen from 1,596 million yen in the previous fiscal year.
・Environmental preservation and maintenance expenses decreased from ¥2,788 million in the previous fiscal year to ¥2,656 million.
・Economic benefits from environmental preservation activities increased from ¥1,820 million in the previous year to ¥2,127 million, mainly due to an increase in the sale price of valuable resources.
