List	Version	Source flow	Name there	Why this flow
EF	3.1	08a91e70-3ddc-11dd-9657-0050c2490048	Dichlorodifluoromethane	The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu	2026-v1	f828df11-a2c9-5772-8d01-ca5c9eb0517d	Methane, Dichlorodifluoro-, CFC-12	The CAS numbers are the same (75-71-8); both name the same compartment.
ecoinvent	3.12	e93ba406-3df8-4e34-be54-0d556b2bb629	Dichlorodifluoromethane	A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.
ecoinvent	3.8	e93ba406-3df8-4e34-be54-0d556b2bb629	Methane, Dichlorodifluoro-, CFC-12	A curator's mapping table (ecoinvent-3.8-biosphere-EF-3.1-biosphere.json) names this flow.
