Latvia reports emissions from cattle (including dairy cows), sheep, swine, goats, horses, rabbits, and fur-bearing animals. Emissions from poultry enteric fermentation have not been estimated. According to 2006 IPCC Guidelines methodology for enteric fermentation calculation from poultry is not developed. However methane emission from poultry is calculated below in the Manure management category. Cattle are the largest source of enteric methane emissions (95.2% from total methane emissions from enteric fermentation) in Latvia. In 2013, dairy cattle produced 64.5% and non-dairy cattle – 30.7% of methane emissions. Emission from sheep made 2.1%, swine – 1.7%, horses – 0.6%, and goats – 0.2% of the total emission from enteric fermentation. In 2013, methane emissions from enteric fermentation of domestic livestock increased by 0.11 Gg or 3.6%, if to compare with 2012. This is caused by the increase of the number of all livestock, excepting goats and horses. The number of non-dairy livestock increased up to 5.7% in 2013. Since 1990 generally due to evident fall of the number of livestock emissions methane emissions decreased by 64.9%.
