Source lists
3| List | Version | Source flow | Name there | Why this flow |
|---|---|---|---|---|
| EF | 3.1 | 08a91e70-3ddc-11dd-9259-0050c2490048 | carbon-14 | The consensus list is built from this one, so this row is the flow itself rather than something matched to it. |
| ecoinvent | 3.12 | 93add24b-0bbf-4903-b3c1-3c695f597c63 | Carbon-14 | The CAS numbers are the same (14762-75-5); both name the same compartment. |
| ecoinvent | 3.8 | 93add24b-0bbf-4903-b3c1-3c695f597c63 | Carbon-14 | The CAS numbers are the same (14762-75-5); both name the same compartment. |

Characterisation factors
4- consensus-flow-list 2
- European Commission — JRC 1
- ecoinvent Centre 1
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.
- 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
