* The weight conversion and density calculation for petroleum fuels were based on international quality standards provided by the Korea Petroleum Quality & Distribution Authority (KPQDA) until 2023.
From 2024 onward, the GHG Protocol’s Emission Factors for Cross-Sector Tools have been applied to the calculation.
* The weight conversion and density calculation for natural gas (LNG) were based on data from California Gas Transmission and air density references until 2023.
From 2024 onward, the GHG Protocol’s Emission Factors for Cross-Sector Tools have been applied to the calculation.
* Electricity emission factors were calculated using the GHG Protocol’s GHG Emissions Calculation Tool until 2023.
From 2024 onward, emission factors from the Carbon Database Initiative (Generation category) have been applied to the calculation.
* Figures have been adjusted due to a change in rounding methodology, which may result in discrepancies compared to the prior year's report.

* From 2024 onward, the calculation of direct energy consumption was based on emission densities derived from the GHG Protocol’s Emission Factors for Cross-Sector Tools,
and the resulting figures may not be directly comparable to those reported in prior periods.
* From 2024 onward, the calorific value for indirect energy (electricity) was calculated using the GHG Protocol guidance value of 3.6 MJ/kWh.
Therefore, the data may not be directly comparable to those reported in prior periods, which were based on the domestic gross calorific value of 9.6 MJ/kWh.
