In 2014, Ukraine signed and ratified the Agreement on associated with the EU. One of the requirements advanced in this Agreement lies in establishing the procedures of monitoring, reporting, and verification of the emissions of greenhouse gases (GG) from power plants. This system is based on the assemblage of procedures for estimating the GG emissions. Greenhouse gases formed at the combustion of organic fuels are CO2, CH4, and N2O. Carbon dioxide is the main GG emitted by power plants. In carrying out this work, we developed a method for the calculation of CO2 emission, formed during coal firing at thermal power plants (TPP), based on the carbon content factors with regard for the low calorific value of coal and heat loss due to unburned carbon. Using this method, we obtained the values of specific carbon content factors, CO2 emission factors and gross CO2 emissions from Ukrainian TPP during the last years. We also calculated the gross GG emissions. In 2018, the GG emissions at Ukrainian TPP were equal to 45.5 mln t of CO2-equivalent.The values of specific GG emissions per unit of supplied electric power constituted 1126 g/kW-h. This parameter reached 1186 g/kW-h for coal of grade A and L, and 1112 g/kW-h for grades G and DG. Ref. 16, Tab. 8.
