Modeling RNG through dairy (manure)

I would suggest that you look at the Day 2 presentation from the webinars that we did last November.
ghgenius.ca/downloads/BC%20LCFS%20Day%202.pdf

There is a hythane pathway in the model. Column BT on the Upstream emissions sheet. It is not very flexible to accommodate RNG and Hydrogen but you can see from the formulas that it is pretty easy to do this outside of the model.

Those values come from Common Reporting Forms that each country completes as part of the National GHG inventory reports.

There are a number of factors that impact the values, ambient temperatures and manure management practices are the two that have the biggest impact. The US is warmer (more methane produced) and herd sizes are generally larger which requires different management practices.
