CARBON FOOTPRINT OF ELECTRICITY PRODUCTION

Abstract

A methodology for calculating the carbon footprint of electricity production has been developed, which meets the requirements of the ISO 14067 standard and the methods of inventorying greenhouse gas emissions of the Intergovernmental Panel on Climate Change. Calculations of the carbon footprint of electricity production using hard coal and natural gas, as well as its components, were performed for all stages of electricity production: during the construction of power plants, fuel extraction and fuel transportation, production and transportation of electricity, and waste management of its production. A comparison of the calculation results with literature data showed a significant excess of the carbon footprint of electricity production, which is produced using hard coal and natural gas at power stations in Ukraine. The reasons for exceeding the carbon footprint of electricity production in Ukraine relative to values in other countries are explained. It was determined that the reasons for such an excess are not only due to different levels of technical condition of power plant equipment, but also depend on calculation methods, in particular, the use of different limits of the life cycle of electricity production. Also (in the case of using natural gas) using different methods of destribution of fuel costs for the production of heat and electricity in the case of combined production of heat and electricity. Expected that the results of the work will be used in the calculations of the products carbon footprint for which uses electricity. Bibl. 18, Tab. 5.
