If I am looking at this result for electricity demand in the demand sector: Direct (Demand) plus Indirect (Transformation) Emissions Allocated to Demands - The upstream emissions allocated to demands are only at the "first level," in other words - it does not allocate emissions upstream of electricity generation (for example natural gas production emissions for natural gas feedstock to electricity generation). I understand this may not be allocated to avoid double counting (for example if you were next looking at natural gas demand direct + indirect emissions). Is there any way to customize how the transformation emissions are allocated in the results view (or is there any plan to implement this capability)? It would be useful to have to extract lifecycle emission factors from the model.

Thank you in advance,

There is no way to modify the built-in results variables in LEAP, but, you could always create a separate Indicator to calculate any auxiliary results you wish.

That said, in testing I find that LEAP (the latest version, at least) does actually allocate all upstream emissions to demand, even if those upstream emissions arise in more than one module. This makes sense to me, and I don't see an issue with the calculations. Can you walk me through an example that illustrates this?

Thanks,

Thank you for the reply. I have a sample model to illustrate (https://drive.google.com/file/d/1Lj4YWcLjeHNpLCCrsQ6S-1lnXsS-K9Fe/view?usp=sharing). I tried to attach it but the file size is too large so please use the link to download. In the sample model:

When I run this model and check electricity demand indirect emissions, the only emissions allocated are those from electricity generation and do not include emissions from natural gas extraction to provide feedstock for the electricity generation. For example - electricity demand indirect emissions result in 5,584 metric tonnes. But total emissions due to the electricity demand (electricity generation and natural gas extraction) are 15,584 metric tonnes.

So my query is - is there the capability (or can there be) or simple workaround to allocate natural gas emissions to electricity demand also? In a simple model like this it would be easy as I can just use total area emissions to calculate the value. But, for more complex models this approach would not work as there could be multiple demands causing upstream emissions from the same feedstock.

This results capability would be useful for finding lifecycle emission factors.

I hope it is more clear. I can try to explain further if needed.

Thanks,

Matt

This result should include emissions from all upstream transformation modules. Hopefully we can fix this,
