Transfer from a mail discussion (to be adapted in the review)

Previously I (Rudy, RP87) send a notification and a mail to Bo's team about the 'post-publication review'.

Dear Rudy, Yes, I also do not read Researchgate notifications... Thanks for taking the time to provide a review of our poster, and sorry for taking so long in responding. So let me reply here to some of the issues you raise:

1) Value judgement re.
"Determining flow" = "Reference flow" in ecoinvent language: No value judgement is intended here. The definition "Product output of an activity for which a change in demand will affect the production volume of the activity" implies an observation of a change in production volume as a response to a change in demand.

The intricacies of this identification are described in detail here: https://consequential-lca.org/clca/determining-or-dependent-co-products/.

As far as I can see this does not require any value judgements, just observation. I believe the description can be converted to computer code, but I have not seen anyone doing that yet.

2) Competency questions for outputs from system models involving value judgements:
While the choice of system model is an obvious value choice, the competency question in case already states this choice implicitly as consequential in the use of the term "due to". Once this question/choice is posed/made, no further value judgements should be necessary, since it follows logically from the question that the system boundaries must be global, infinite, and not applying by-product cut-offs.

Of course, the database can be used to answer many other questions that imply different system boundaries. In this respect, the specific competency questions are only exemplary.

3) The license question
