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 CO2 emission factor for Korean coal briquettes is 95,558 CO2 Kg/TJ. It is lower than the local anthracite CO2 emission factor, 111,100 CO2 Kg/TJ and the 2006 IPCC Guidelines, 87,399 CO2 Kg/TJ by about 13.99 and 2.79%, respectively.
