| Other Indirect Emissions (Scope 3) 5) | tCO2eq | 11,782,373 | 10,332,725 | 12,353,667 | ||
- 1) Emissions calculated by deducting offsets through Green Premium purchases from greenhouse gas emissions (Scope 1 and 2).
- 2) Scope 2 market-based emissions calculated in accordance with the standards of the global RE100 operating body (CDP)
- 3) Based on seperate (non-consolidated) financial statement revenue
- 4) Shipment volume is based on the combined total of the Ulsan Terminal, Pyeongtaek Terminal, and G.Hub
※ As revenue is affected by external factors such as oil prices and exchange rates, product shipment volume, which is linked th SK Gas's sales results, is used as the basis for calculating intensity - 5) The Scope 3 calculation boundary covers Categories 1-8, 10, 11, 13, and 15, of which Categories 1, 10, and 11 were business sited
- 6) A total difference of 2 tCO2eq arises because the emissions in the greenhouse gas verification statement are rounded down to the nearest whole number for each business site
