OverseerFM automatically generates GHG emission reports for the farm analysis based on the farm management information entered and using a series of default transport and fuel use settings based on national averages.
The GHG input tab provides a way to override default values for on-farm fuel use, fertiliser application transport method, supplement and animal transport.
Assumptions in the default settings are set out in the green help boxes.
The impact of transport emissions on a farm (including arable) are typically small, so unless accurate fuel and transport information is available we do not recommend over-riding the default settings. If GHG emissions information is being used to support a business carbon certification process, then more detailed information will be required.
