* Scope 3. : Other indirect emissions are calculated using the Emission Unit Value Database(ver. 2.6) as per the Ministry of the Environment’s Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain (ver. 3.4).

For public transportation such as trains and buses, we calculated using "transportation allowance x emission intensity" for each means of transportation.
For private cars, we used "person-km x emission intensity" based on the employee's travel distance and recalculated going back to 2019.
From the Ministry of the Environment's "Emission Intensity Database (ver2.6)"

6. Conversion factors used for heat consumption amount and CO₂ emissions

Conversion factors (variable factors) used for 2023 results in the Environmental Plan 2050

* With regard to actions relating to the Environmental Plan 2050, results for 2019 onwards are calculated using variable factors and therefore cannot be compared with past data.
