how to get access to weighting impact method in PSILCA for social life cycle impact assessment

Question

Hi,
I hope you are doing well. I am writing to ask you how it is possible to have access to the impact weighting method in PSILCA database for social assessment. Should we buy impact method separately from PSILCA database like other impact methods in environmental LCA?
that is a question I have. because I am trying to do the analysis with the impact pathway method using the impact weighing assessment method, but i cannot get the results. All the med risk hours are in zero.
THank you for the help and time
Regards

Answer 1

Hi Laleh,

the method is in the database already, but it is very simple; there is no need to buy an additional method. Can you post a picture about the 0 impacts? Which database version are you using?

Thank you,

Andreas

edit to reflect your second answer below: I guess you are looking at the raw value version of the database? This does not contain the method, the method is on the worker hour version. You can export it (as JSON-LD) if you want. A process will not have direct social impacts if it does not have any indicators (to your second question again).

PSILCA V3_1_1, but is doesn't have the method. is it possible to export from another database?

Answer 2

Hi,
I have added some of the results including the contribution tree and Sankey diagram. I don't understand the reason behind that. Is it correct to have direct and indirect impacts 0 for one unit process?
