Why do I get zero results for all impact categories in PSILCA impact assessment

Question

I have used the same method, and database in building a similar product systems in PSILCA. However 3 of the product systems out of 9 ; results in zero medium risk hours in the same impact assessment method. What could be the issue?

Answer 1

This will depend on your product systems, and the indicators used in the processes - ideally post some details? Thank you!

Edit: thank you for your pictures! From what you post though I cannot spot a reason. In the process screenshot, do the providers alone produce results (if you calculate the product of "Ani.." separately)? And in the project, the amont of (new).., Beef F etc. is also 1 (you show I think those systems with an amount of 1 that produce results). Thank you again.

Hi Andreas, Thank you for your respond. I have pasted the screenshots in my original question.  I have used the same modelling approach for all the 9 product systems that are produced in various countries. I did not pre-select /modify the social indicators or risk levels, and basically in the output I used per 1usd output. At the end 3 of the product systems did not give any results but the rest 6 did.

Answer 2

This is one of the product system that had zero results

And below is the comparison of all the product systems. Among them 3 of them had zero results
