What principles are used when building the process of different locations? what's the differece?

Question

I find if we chose different provider processes of different locations, such as ROW, GLO, and US, they do result in different LCA results. and when I open the provider to compare the input and output of these processes, I find that most of the flows are the same, but some of these are different. So what principles are used when building the process of different locations? when they reference the same flow but from different providers, how do they allocate the amount?

Answer 1

Well this is just as always when modeling a process, ideally, the inputs and outputs reflect reality. When you run an electric engine in France or in Germany, you have just a different electricity input, when you grow grapes in France or in Germany, you have a much different yield and result, and need different fertilisers maybe etc., and this is reflected in your process.
