Combustion of lignite and coal comprises the most important part of CO₂ emissions in the Czech Republic (CR). The IPCC methodology on national greenhouse gas inventories provides default values of emission factors for the basic tier (the simplest level of methodological approach), including those for lignite and coal, which do not represent the specific national conditions. Therefore, this methodology indicates that more accurate country-specific emission factors based on national data should be used for the significant categories of sources, called key categories. This paper presents the results of recent research that was concerned with updating country-specific emission factors, which would be able to accurately describe CO₂ emissions from combustion of coal and lignite in the Czech Republic for the whole time period from 1990 to the present year (2016). Development of these factors was based on the evaluation of relevant correlation dependence of emission factor on net calorific value. In addition, the research was supplemented by assessment of relevant country-specific oxidation factors for lignite and coal.
