List Version Source flow Name there Why this flow
EF 3.1 fe0acd60-3ddc-11dd-a8d9-0050c2490048 methacrylate The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
agribalyse 3.2 3b234b74-e6fd-52ee-b9ed-8b442bee891b Methyl acrylate The CAS numbers are the same (96-33-3); both name the same compartment.
bafu 2026-v1 6161113d-a1b5-5ef3-88ac-e61b2a4b34a8 Methyl acrylate This substance answers to the name the row carries; both name the same compartment.
ecoinvent 3.12 6994b171-4ce1-4877-9c17-c206180fcea3 Methyl acrylate The CAS numbers are the same (96-33-3); both name the same compartment.
ecoinvent 3.8 6994b171-4ce1-4877-9c17-c206180fcea3 Methyl acrylate The CAS numbers are the same (96-33-3); both name the same compartment.

Characterisation factors

16

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.
