Python-Script for Mulitple Product Systems at once & several product systems simultaneously

Question

Hello,

I have created many processes and would like to create product systems for all of them and then calculate them all together using the same LCIA method and have the results in Excel format.

I don't want to create and calculate all product systems individually. I have found similar questions here and also Python scripts for this. However, the script for creating multiple product systems does not work for me. Instead of opening the dialog box to select multiple processes, it opens an error.

The questions (and answers) I found are from 2020/2021. Unfortunately I don't know Python, could it be due to the new OpenLCA version (I use OpenLCA 2.2.0.)? Or is there something else I need to consider? Or a new Python script that I have overlooked?

Answer 1

We provide a super-fast Python/Jython script for this in Nexus, but for a fee, if calculates e.g. entire ecoinvent 3.10 in a few minutes, and provides LCIA results in an excel file. The script can be run directly in openLCA.

How much is the fee? Thanks.

it is here: https://nexus.openlca.org/utility/Special%20Python%20Scripts. Not exactly cheap but really worth it I think.

Nexus website seems to have 404 error.
