Papers considered
Three papers were presented to the panel for consideration:
- Uncertainty of Agricultural Soils emissions
- New emission factors for nitrous oxide from farm dairy effluent (FDE) and urea
- Revised equations for calculating methane from sheep
Outcomes
The panel agreed to the recommendation that the method outlined in the manuscript by Kelliher, Henderson, and Cox (2016) be used to estimate emissions uncertainty from agricultural soils.
The panel wanted MPI to clarify the best emission factor estimates for FDE and urea, and recommended that these values (once clarified) be adopted and used in the inventory.
The Panel agreed to the new sheep methane equations being included in the inventory.
