Biojet Node reads every African state against the same five value-chain stages, from the public record, source by source. The same frame is applied to every country, so the map compares like with like — what the record shows, and where it is silent.
A SAF claim is a chain. It runs from the field to the wing, and it lives or dies on the last link — traceability, registry, and MRV. A litre that cannot be traced and verified is not, for our purposes, sustainable aviation fuel.
Each stage is shaded on a single-hue sequential green ramp by the strength of its public evidence. The same reading is repeated as a glyph, so the map survives greyscale printing and colour-blindness — colour is never the only signal.
Where the record is silent, the cell reads “no public evidence.” This is an open question to be closed — a prompt to go and look harder — not an assertion that a country lacks the capability.
Absence of evidence is not proof of absence. A gap on the map is a gap in the public record as we have read it — and an invitation to send us the source that closes it.
Nothing on this map is synthetic. Every reading traces back to a dated, public source — ICAO Feasibility Studies, State Action Plans, certification registries, and the framework documents catalogued on the sources page. No live pricing. No on-chain claims. This is a public-record intelligence layer — a structured reading of what is already in the open, not a market feed and not a ledger.
