Is the data quality entry based on my own evaluation?

Question

Hi. When modeling processes in OpenLCA and using datasets from the ecoinvent database, I’ve noticed that the data quality entry is empty. I understand that I can edit and score it from 1 to 5, but I’m not sure how to determine the correct score. Is this something I should evaluate myself based on the datasets I’ve used in my processes, or should I refer to similar processes with the same dataset and use their scores? The issue is that even similar processes can be very different, so I’m unsure about the criteria I should follow.

Hi,

yes. Just continue with the data quality system provided by ecoinvent in your own processes and assign the data quality according to the logic given (there is a text for each box you click). Find more information here: https://greendelta.github.io/openLCA2-manual/advanced_top/data_quality.html
Hope this helps
