GHG Emissions

GHG Emissions
Category Unit 2023 2024 2025
Direct Emissions (Scope 1)1 tCO₂eq 222.9 253.8 212.6
Indirect Energy Emissions (Scope 2) 22 45.1 50.3 50.0
Scope 1 + 2 Total 268.0 304.1 262.6
Scope 1 + 2 Emissions Intensity³3 tCO2eq/bn 157.1 176.8 159.9
Other Indirect Emissions (Scope 3) tCO₂eq 2,770.2 2,953.4 3,394.6
Grand Total (Scope 1 + 2 + 3) 3,038.1 3,257.5 3,657.3
  • * Due to the revision of the Scope 3 Category 15 emissions calculation methodology, the Scope 3 emissions figures for 2023 and 2024 have been revised.
  1. 1 Direct emissions from natural-gas consumption at HQ plus fuel burned by company vehicles operating at HQ and project sites
  2. 2 Scope 2: Greenhouse gas emissions from electricity consumption at the headquarters office and the operation of electric vehicles at project sites.
  3. 3 Emission intensity is calculated by dividing total GHG emissions by revenue reported in the separate (non-consolidated) statement of profit and loss.

Total Energy Use1 4.5 5.0 4.5
Energy-Use Intensity2 TJ/KRW 100bn 2.6 2.9 2.7
  1. 1 ”Total energy use” combines HQ natural gas and electricity with fuel consumed by HQ and site vehicles; the latter is estimated from fuel invoices and mileage records for the company fleet.
  2. 2 Energy-use intensity is total energy use divided by revenue in the separate (non-consolidated) statement of profit and loss
