impact factors in impact analysis are not showing up

Question

Hi,

i am new to Open Lca. I am using the probas + data. when I calculated my product system ther are no impact factors in the impact analysis shown. Does anybody know how I could get them? Do I have to download something into my database?

Answer 1

Yes, you have to download the impact factors from the nexus first and import them:

ah....  have you tried open the process?
(click on the arrow next to the purple P (>P))
I can only see impact factors for flows.

how can I insert a screenshot here?

Answer 2

play around with your allocation method, I had to change mine to "none" in order to generate impact results. leaving it as defined in process gave zero results for everything
