Preliminary GHG Emissions Inventory for the Slovak Republic

This paper presents preliminary results of a greenhouse gas emissions inventory for the Slovak Republic. The key gases included are carbon dioxide, methane, and nitrous oxide. Chlorofluorocarbons are excluded because they are controlled under the Montreal Protocol. Estimates of emissions are calculated by applying the IPCC Methodology. Fossil fuel combustion accounts for about 96% of total Slovak CO2 emissions from energy, industry, and waste incineration. The most significant industrial sources of carbon dioxide emissions in 1990 were cement, magnesite, and coke production. Forestry and land-use change were responsible for a net uptake of 4,720 gigagrams (Gg) of carbon dioxide. Total net emissions of carbon dioxide in 1990 were 53,594 Gg CO2. The main sources of methane emissions are livestock, natural gas distribution networks, and landfills. Total methane emissions in 1990 were estimated to be 345 Gg CH4. The estimated emission of 20 Gg N2O is very preliminary. The main sources were agriculture and wastewater treatment. To evaluate the shares of different greenhouse gases in relation to total emissions, aggregated emissions were estimated based on both the direct and indirect effects. Carbon dioxide emissions amount to 78% of total emissions, methane emissions amount to 13%, and nitrous oxide emissions amount to 9%.
