Abstract: In this article, we calculated methane emissions from enteric fermentation in ewe farming in 2015 and 2016. Subsequently, we investigated the causes of differences in their amounts in the observed years. We used established methodology (2006 IPCC) for calculation and we also accepted country-specific conditions of sheep farming. The amounts of methane emissions were dependent on their emission factors and the number of ewes in that year. In 2016, the average value of methane emission factor reached the value of 10.21 kg per ewe and year, which was 0.12 kg per ewe and year less than in 2015. We kept 155,828 ewes, which was 4,107 less than in 2015. The decrease of these parameters caused a decrease in amount of total methane emission in this year. The total methane emission from enteric fermentation represented 1,591.5 t of methane in 2016, which was 60.2 t less than in 2015.
