Greenhouse gas emissions of the nation should be precisely assessed in order to effectively tackle the problems stemming from climate changes. To do so, country-specific data that reflect a nation's distinct characteristics must be applied to more precisely assess greenhouse gas emissions. In this research, carbon emission factors were assessed for emission sources making up over 53% of the domestic anthracite consumption with calorific values of fuels and elementary analysis. Furthermore, oxidation rates were assessed based on measurement results of unburned carbon produced from tested power plants to calculate CO2 emission factors. Ultimately, the CO2 emission factor was calculated at 106,747 kg/TJ, about 9% higher than the anthracite emission factor presented by the Intergovernmental Panel on Climate Control. Such differences are assumed to mainly come from disparities of anthracite properties along with combustion technology and differences of oxidation rates depending on the combustion conditions. Therefore, continued research on a wide variety of fuels and energy consumption facilities should be conducted in order to establish countryspecific data, which will help more accurately assess greenhouse gas emissions and subsequently will lead to reliable greenhouse gas reduction goals.
