I have been investigating different methodologies to model GHG emissions with LEAP for the agriculture sector using a detailed livestock stock model I have access to. I was wondering if anyone in SEI or the online community here could point me in the direction of studies like this which have already been completed using LEAP as it can be difficult to merge the low energy demand/ high emissions traits of the sector.

All the best

Thanks very much for starting this topic. It sounds interesting. I am also thinking about that.

I am also interest if energy consumption at one dairy farm is possible to express per animal. Certain difference should be among the size of herd and way of housing (if there are cows all time in barn or have access to pasture/yard). I believe that energy consumption have inverse linear relation to herd size (number of animals), to a certain number of cows. Some farms with lower number of cows (bellow 10-15) maybe could be out of this rule.

Please let me know if you have experience there.

This morning I listen one interesting podcast about your topic: https://www.bbc.co.uk/radio/play/b0bgp869

Maybe you could search more on Dutch approach.

Thank you for getting back to me on this topic,

I thought I would let you know what I did in the end to address this question, I constructed a separate model in excel which accounts for GHG emissions originating from Livestock, Pasture and Tillage, some other details are also included. I used this data to calculate annual GHG loading's for each agri type and animal etc then linked them to my LEAP model within the Non-Energy folder, adding CH4 and N2O emissions here. I am happy that this adequately captures the emissions for which I have data - I have separately created a couple of scripts which then allow me to update figures within the excel sheet and push these to LEAP if I wish to conduct sensitivity analysis of herd size, emissions per head etc.

The screenshot below shows a sample of the results I am getting for 2015 for one run of herd size
