(*1) W = Global emissions; EF = Regional emissions from sources calculated with the emission factor; GEF = Emission factor with spatial distribution of regional emissions using proxy spatial distribution; GPM = Model-based emissions calculated on a grid scale; in some cases, a specific approach is used for a gas species and deviates from the approach for the other gases; (cc) indicates variable emission level under climate change.
(*2) GPM for dairy and non-dairy cattle, emission factors for other animal categories.
(*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.
(*4) Modelled deforestation is used
