List Version Source flow Name there Why this flow
EF 3.1 45ff0ff8-c173-45c1-ae75-80d77994f79f Hydrocarbons, aliphatic, alkanes, cyclic The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
agribalyse 3.2 c2491f63-b413-5143-b3bf-9d67a0adec8e Hydrocarbons, aliphatic, alkanes, cyclic This substance answers to the name the row carries; both name the same compartment.
bafu 2026-v1 238edffd-c6fb-5e43-9248-569b3f9b8414 Hydrocarbons, aliphatic, alkanes, cyclic This substance answers to the name the row carries; both name the same compartment.
ecoinvent 3.12 18282ab8-5b46-4c56-9038-588ed28a4a95 Hydrocarbons, aliphatic, alkanes, cyclic This substance answers to the name the row carries; both name the same compartment.
ecoinvent 3.8 18282ab8-5b46-4c56-9038-588ed28a4a95 Hydrocarbons, aliphatic, alkanes, cyclic This substance answers to the name the row carries; both name the same compartment.
ecoinvent 3.8 2a042136-80fd-4c1c-8996-65a7985497d3 Cyclohexane (for all cycloalkanes) The row carries a name ecoinvent retired, and the vendor's own crosswalk says this substance is what it became; both name the same compartment.

Characterisation factors

2

Every implementation that says anything about this flow. Published as is what this list did with the row: where more than one implementation states a number and they agree it publishes it as agreed; where only one speaks, as sole; where they disagree it publishes nothing and asks.

Something wrong here?

A flow can be wrong in three ways, and they are decided differently. Pick the one that matches what you are looking at.

You do not need to run a build or clone anything. Name the row and say what your evidence is; the measurement is done for you. How contributing works
