Korea adheres to the basic emission factor proposed by the Intergovernmental Panel on Climate Change Guidelines to calculate the greenhouse gas emission. However, the Intergovernmental Panel on Climate Change Guidelines recommends applying an emission factor unique to a country, which reflects its features in fuel consumption. Especially, there has been little research in emission factors and in the amount of Korean coal briquettes used in Korea, and even worse, the Intergovernmental Panel on Climate Change Guidelines has not proposed the basic emission factor for such briquettes. Recently, the Korean government has made efforts to calculate greenhouse gas emission factors for each sector, and it is requiring research and development be conducted in the greenhouse gas emission factors of Korean coal briquettes in household and commercial sectors. The amount of carbon, hydrogen, and calorific values in the input fuel was measured using a calorimeter, elemental analyzer and proximate analyzer. For fuel analysis, the CO 2 emission factor for Korean coal briquettes is 95,558 CO 2 Kg/TJ. It is lower than the local anthracite CO 2 emission factor, 111,100 CO 2 Kg/TJ and the 2006 IPCC Guidelines, 87,399 CO 2 Kg/TJ by about 13.99 and 2.79%, respectively.

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 CO 2 emission factors. Ultimately, the CO 2 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.
