The Farm Carbon Calculator is generally designed to calculate the footprint of a whole farm, but it can also be used to generate product footprints.
To do this you will need to create an Overheads report to capture things that are common to the whole farm, such as Machinery, Buildings, Woodland and Hedges. We have a detailed guide to setting up an Overheads report in the Resources section.
For instance, you might have dairy cows, an arable operation, plus beef. You can calculate the footprint of any one of those separately if required.
First of all, work out what processes and inputs are used specifically for each of the three enterprises. Then work out what is common to all enterprises - e.g. buildings, machinery, office, woodland, hedges, etc. For these common elements, put everything in an Overheads report. This Overheads video offers a walk-through guide.
Then create a product report (e.g. 'Wheat 2022') - add in the Overheads report, then all the inputs used for the wheat - e.g. diesel, electricity, fertiliser, distribution, etc. This will give you an accurate footprint for the wheat out of your farm.
Repeat the process for the dairy and beef enterprises.
