X denotes link between source and gas or aerosol.

Approach:

  • 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.

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
