Hill, Upland and Crofting Farmer-led Group: climate change evidence

A summary of existing evidence around Hill, Upland and Crofting (HUC) farming, including greenhouse gas emissions produced by the Rural and Environment Science and Analytical Services (RESAS) division.


Annex C – GHG Inventory Assumptions

Estimates of emissions by broad sector have been derived in line with descriptions in the inventory. Not all sources are disaggregated into specific sectors therefore the following sources in the inventory have been attributed based on the following percentages.

Table C1. Emission source attribution
IPCC Source Name Crops Dairy Deer Goats Horses Beef Pigs Sheep
3H_Urea application Fertiliser application 80% 20% 10%
1A4cii_Agriculture/Forestry/Fishing:Off-road Agriculture - mobile machinery 60% 30% 20%
3A4_Enteric_Fermentation_other_livestock Enteric 7% 1% 67% 25%
3D11_Inorganic_nitrogen_fertilizers Grass - Direct 30% 60% 10%
3D14_Crop_residues Grass - Direct 30% 60% 10%
3G1_Liming - limestone Liming 50% 15% 30% 5%
3G2_Liming - dolomite Liming 50% 15% 30% 5%

This results in the following estimates of GHG emissions for agriculture in 2018:
