|---|---|---|---|---|
| EF | 3.1 | fe0acd60-3ddc-11dd-9fe5-0050c2490048 | 1-pentene | The consensus list is built from this one, so this row is the flow itself rather than something matched to it. |
| bafu | 2026-v1 | 2c34354b-4a23-5173-aeaa-b38c66dc0c84 | 1-Pentene | The CAS numbers are the same (109-67-1); both name the same compartment. |
| ecoinvent | 3.12 | ccfea48e-0aec-4573-8ed1-fb7c0f1b14ae | 1-Pentene | The CAS numbers are the same (109-67-1); both name the same compartment. |

}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.
- A row from my list should not reach this flow
- This flow is not that chemical
- The compartment or the unit is wrong
- One of these characterisation factors cannot be this substance's
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
