Data compilation (Environmental report)

Performance data for our environmental initiatives is divided into 10 categories of action under our Eco Vision 2025.
Changes in data over time are primarily based on the previous five years.
(Exceptions: Items listed that have a period of data collection of less than five years and items that have a specified base year)

Calculation methods were changed in fiscal 2021
• Scope 1 emissions are calculated based on the GHG Protocol and IPCC guidelines.
• Scope 2 emissions are calculated based on market standards.

Proportion of total CO2 emissions throughout value chain

The proportions expressed in the graph are based on the international guideline "GHG Protocol Scope 3 Standard" related to the calculation and reporting of CO2 emissions throughout the value chain.

* Of the "scopes" (scope of emissions) for greenhouse gases: (a) Scope 1 emissions are direct GHG emissions from the entity such as gasoline or the combustion of heavy oil; (b) Scope 2 emissions are indirect GHG emissions resulting from the generation of electricity; and (c) Scope 3 emissions include indirect GHG emissions from related activities undertaken outside of the entity such as raw material procurement, production, disposal, logistics, and sales.

Amount of CO2 emissions in logistics / Physical production and sales (Unit: 100 million yen) [DENSO Corporation]

We have achieved CO2 emissions reductions from our logistics operations through efforts to improve these operations, including the enhancement of vehicle load rates, the promotion of a modal shift (shift toward use of railways and sea vessels), and the shortening of transportation distance to delivery destination.
