Methods:

• W = Global emissions;
• EF =Regional emission factor applied to the specified activity level;
• GEF = Grid-specific emission calculated from gridded activity level and (regional) emission factor;
• GPM = Gridded, model-based emission (statistical or process-based model).

Footnotes:

GPM^*2: GPM for dairy and non-dairy cattle, emission factors for other animal categories.

GEF^*3: NH3 emissions from animal houses, manure storage and grazing livestock are based on emission factors; emissions from manure spreading are based on a grid-scale model.

GPM^*4: Modelled deforestation is used
