* Scope 3. : Other indirect emissions are calculated using the Emission Unit Value Database(ver. 2.4) as per the Ministry of the Environment’s Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain (ver. 3.2).
*Scope 3. : For 11. Use of products sold, we changed usage conditions such as yearly distance used (hours) and years of use across lifetime (hours), and also changed calculation conditions using power coefficient scenarios for each region based on future electrification of products. Figures were recalculated accordingly, dating back to 2019.

6. Conversion factors used for energy consumption and CO2 emissions

Conversion factors (variable factors) used for 2021 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.
