EN15804 ADD ON vs Ecoinvent 3.9.1

Question

I have two providers for a process e.g.

steel production, converter, unalloyed | steel, unalloyed | EN15804, U and

steel production, converter, unalloyed | steel, unalloyed | Cutoff, S

The first one is from the new EN15804 add on and the second one is from the Ecoinvent 3.9.1

All the general information are exaclty the same and both of them are Systems even though the first one has the U characterization.

What is the actual difference?

Answer 1

Well the EN15804 process is definitely not a system process?

edit, in reflection of the comment: in the database we release on Nexus, there are only these two processes with this name, both are unit processes:

To the previous comment (how big is the effort): you will need to modify the datasets. The initial version took as maybe half a year (but including review discussions, and conceptual thinking).
