Upstream sectors ins PSILCA can not be calculated, are results still correct with suitable system boundaries?

Question

I have a question about the social aspects of the sectors in PSILCA. There are social aspects for each sector. Why do I need all sectors as input for a sector to get a correct result. I thought I only need the social aspects of individual sectors that I select for my system to get a reliable result. I don't understand what the ‘background’ sectors ‘do’. I hope you understand my problem and can help me to get a better understanding. Since my product system can not be calculated (even though I am already using a cut-off of 10E-03), I had to delete the upstream flows (background sectors) and just work with the "first" sectors.

Hi Marie, the upstram sectors are needed to get life cycle results.

Regarding your "my system cannot be calculated": please check and use the PSILCA libraries that we have put now on Nexus. With this a calculation should be really feasible, and also really fast.

Hth, Andreas

Yes, your system is only the process itself then (but that is not the idea of a life cycle assessment evidently)
