- Scope
- GWP100 (IPCC AR6), cradle-to-gate
Directional cradle-to-gate estimate (GWP100, IPCC AR6). Material factors are full cradle-to-gate, but our own synthesis steps carry no process energy, so the route value is a lower bound. Screening values are modelled from the molecular formula (±30%, simple C/H/O molecules only) and are not third-party verified (not ISO 14067 / TfS defensible). For indicative comparison only; producer-maintained values with a source take precedence.
