View image in the official sourceis the total emissions from residues and tillage events and soil landscape modification activities during year B of the baseline period BP for the project area PA, in tonnes CO2-e, worked out using equation 23.
View image in the official source is the emissions from diesel fuel used for tillage events and soil landscape modification activities in year B of the baseline period in project area PA, in tonnes CO2-e, worked out using equation 24.
View image in the official sourceis the emissions from the residues of all crop types in year B of the baseline period in project area PA, in tonnes CO2-e, given by equation 25.
Note: To avoid doubt, sowing with tillage (e.g using discs or tynes) is considered tillage.
View image in the official sourceis the emissions from pasture tillage events i in year B of the baseline period in project area PA, in tonnes CO2-e, worked out using equation 27.
View image in the official source is the emissions from the residues of all cover crops in in year B of the baseline period in project area PA, in tonnes CO2-e, worked out using equation 28.
(3) For equation 23, is worked out using the following equation:

View image in the official sourceis the estimate of the diesel fuel use in kilolitres per hectare determined by the Supplement for tillage events
View image in the official source is the energy content factor for diesel fuel set out in the NGER (Measurement) Determination, in gigajoules per kilolitre.
View image in the official source is the emissions factor for each gas type g for diesel fuel set out in the NGER (Measurement) Determination, in kilograms CO2-e per gigajoule.
View image in the official source is the quantity of fuel used for soil landscape modification activities in year B of the baseline period in project area PA, in kilolitres.
Note: The value 1000 converts kilograms to tonnes.
View image in the official sourceis the emissions from the residues of crop type v in year B of the baseline period in project area PA, in tonnes CO2-e, worked out using equation 26.
n is the number of crop types and residue burning combinations (burnt/unburnt) grown in year B in the project area PA.
v is the crop type as specified in the Supplement and residue burning status (burnt/unburnt)
Note: If residue burning only occurred for certain paddocks of a crop type, Equation 26 is repeated for the burnt and unburnt crop (with the harvested crop quantity attributable to paddocks of each status).
View image in the official sourceis quantity of harvested crop by crop type v in year B of the baseline period in project area PA, in tonnes of harvested crop type v.
