The total population of livestock in Estonia has been decreasing since 1990, enteric fermentation from cattle is a key source in the national inventory, accounting for about 95% of methane emissions from livestock (Estonia NIR 2017). Manure management methane emissions from dairy cattle are a key category by trend. Estonia began using a Tier 2 approach for cattle enteric fermentation emissions in 2007, and subsequently adopted Tier 2 approaches for manure management methane emissions and methane emissions from pigs in 2010. This case study describes the countries approach for cattle, sheep and pigs.
