openLCA export results showing wrong impact values

Question

I’m using openLCA for a quick Kolkata FF (FF) LCA project and I think the impact results are messed up.  

I make a product system with a few processes and when I export results for global warming impact (GWP100), the numbers don’t match what I expected from the inputs.

I even tried different LCIA methods and still weird numbers. I’m new to openLCA — is there something I’m doing wrong with the export or calculation setup?

Any idea why this happens and how to fix it?

Answer 1

First - welcome!

Hm so the export will reflect the calculated result, thus the question is probably why the result that is calculated is not what you expect. Could you expand here more? Simply edit your question, thank you!

Answer 2

Hi, the issue may be related to the LCIA method, impact category, or calculation setup rather than the export itself. I’d suggest checking that the correct product system, LCIA method, and impact category are selected before exporting the results. Also make sure the database and units are consistent.
