Introduction: Korea has been making efforts to reduce greenhouse gas (GHG) emissions, including a voluntary commitment to the target of a 30% reduction, based on business-as-usual of the total GHG emission volume, by 2020; 2006 IPCC Guidelines provided default values, applying country-specific emission factors was recommended when estimating national greenhouse gas emissions., Results and Discussion: This study focused on anthracite produced in Korea in order to provide basic data for developing country-specific emission factor. This study has estimated CO(2) emission factors to use worksheet of which five steps consisted according to the fuel analysis method., Conclusion: As a result, the average of net colorific value for 3 years (2007∼2009) was 4,519 kcal/kg, and the CO(2) emission factor was calculated to be 111,446 kg/TJ, which is about 11.8% lower than the 2006 IPCC guidelines default value, and about 7.9% higher than the US EPA emission factor.
