In openLCA, is it not possible to calculate the LCA result by separating the upstream and the cores stream as attached picture? Please help, me.

Hi, good question, you see this:

- for the process, aggregated over all occurences of the process in the life cycle model, in the sankey diagram

- for one "branch" in the life cycle model, in the contribution tree (direct impact of the process is impact minus sum of the entries below this process)

- and the direct impacts only in the impact analysis sheet in the process editor.

A distinction of foreground and background system (if rather this was your question) is possible via tags, we will explain this in more detail for the new version.

Hth, Andreas

Hi Andeas,

thanks for mentioning the "tag" functionality and the new openLCA version!

Can you tell me, if the function is already fully functional in version 01.11.? I ran some tests and assigned tags to processes within the product system but could not find a way to make use of them during the analysis of the results.

Thanks a lot in advance!

Best regards,
