Dr. Gary Lanigan:

I think I do. On a dairy farm with two livestock units per hectare, each of cows produces approximately 3 tonnes of methane in CO2 equivalents. That is 6 tonnes of CO2 equivalents and when the fertiliser is added in it comes to approximately 10 tonnes per hectare. The problem we have with the peat soils is that we are using tier 1 emission factors at the moment, which are essentially these generic emission factors.
