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.

Domestic Greenhouse Gas Emissions (DENSO CORPORATION + Domestic Group Companies)
(Thousands of t-CO₂e)
	Fiscal 2019	Fiscal 2020	Fiscal 2021
CO₂	1,169	1,118	1,083
CH₄	12	12	10
N₂O	3	3	3
HFCs	22	2	2
PFCs	39	49	55
SF₆	8	11	11
Others	2	0	0

For reference: Basic rationale on the calculation of total greenhouse gas emissions

At DENSO, all greenhouse gases defined in the Kyoto Protocol are cumulatively calculated, specifically, CO₂ (an energy-related greenhouse gas) and five gases (non-energy-related greenhouse gases), including PFC, HFC, SF6, N₂O, and CH4. The emission coefficient set by region is the conversion factor for CO₂ at DENSO.
In Japan, the Company uses the conversion factors shown in the table below. Outside Japan, DENSO uses the factors publicly announced in each global region.

Please note that in this report the reduction effect of CO₂ by co-generation is converted by the average of conversion factors for different types of thermal power generation. The effect of co-generation is included in the CO₂ emissions of the Company. As for the emissions of the five gases, from fiscal 2007, the Company began using the instructions of the Law Concerning the Promotion of the Measures to Cope with Global Warming enacted and enforced in Japan.

Conversion factors for CO₂ used in the calculation of CO₂ emissions

Electricity	0.453kg-CO₂/kWh
Heavy fuel oil (A)	2.71kg-CO₂/L
Kerosene	2.489kg-CO₂/L
Propane	2.999kg-CO₂/kg
Light crude oil	2.585kg-CO₂/L
City gas	2.171kg-CO₂/m3
