AB - The revised Intergovernmental Panel on Climate Change (IPCC) guidelines for  national greenhouse gas (GHG) inventories recommends that more comprehensive  and thus more reliable characteristics of the local fossil fuels should be  used for the national GHG inventory calculations. This paper deal with the  carbon emission characteristics of low-calorific lignite recovered from the  Kolubara open-pit mine. The samples of coal were carefully selected in order  to cover the net calorific value, ash and water content of the broad  spectrum of the quality of the raw lignite supplied to the Serbian thermal  power plants. Correlation analysis of the laboratory analysis data gave a  linear dependency of the net calorific value on the combustible content in  the coal samples. Also, linear correlation between the carbon content and  the net calorific value was found. The regression analysis of experimentally  determined coal characteristics implies that the carbon emission factor is  dependent on the net calorific value. For the subset of raw lignite samples  with the net calorific value Qdr = 6 ÷ 10 MJ/kg, that is most representative  for current and near future use for power generation in Serbian thermal  power plants, the linear dependency CEFr (tC/TJ) = 34.407 - 0.5891×Qdr  (MJ/kg) was proposed. Regarding the net calorific ranges of samples  examined, the raw Kolubara lignite carbon emission factor is considerably  higher than those recommended by IPCC Tier 1 method of 27.6 tC/TJ.
