Source lists
4| List | Version | Source flow | Name there | Why this flow |
|---|---|---|---|---|
| EF | 3.1 | fe0acd60-3ddc-11dd-a8ea-0050c2490048 | methane (biogenic) | The consensus list is built from this one, so this row is the flow itself rather than something matched to it. |
| bafu | 2026-v1 | 9fa66e4e-eaf8-5e1c-aa7d-c7701ce9617b | Methane, Biogenic | Several substances share the CAS number (74-82-8), and the row's name picks this origin -- fossil, biogenic, and so on; both name the same compartment. |
| ecoinvent | 3.12 | baf58fc9-573c-419c-8c16-831ac03203b9 | Methane, Non-fossil | A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow. |
| ecoinvent | 3.8 | baf58fc9-573c-419c-8c16-831ac03203b9 | Methane, Non-fossil | A curator's mapping table (ecoinvent-3.8-biosphere-EF-3.1-biosphere.json) names this flow. |
