B. Livestock characterizations
A single livestock characterization is critical to the estimation of greenhouse gas emissions from the Agriculture Sector, especially since information on livestock is needed to estimate the feed intake and quantity of manure produced, that are used in estimates of:

• CH₄ emissions from enteric fermentation;
• CH₄ and N₂O emissions from manure management;
• N₂O emissions from agricultural soils (direct, indirect, and animal production).
