There’s not remotely enough feedstock to match demand. SAF is greenwashing.

Heavy on the smoke.
SAF does nothing to address most of aviation’s climate harms, which come from contrail-induced cirrus, NOx, and other non-CO2 emissions.
Only electric flight is climate safe. If that means no flying until electric planes arrive, so be it.

**Kerosene-type jet fuel (including Jet A and Jet A-1, JP-5, and JP-8)** has a carbon number distribution between about 8 and 16 (carbon atoms per molecule); wide-cut or naphtha-type jet fuel (including Jet B and JP-4), between about 5 and 15.[2][3]

**Solar energy can be used to convert basic chemical feedstocks such as carbon dioxide (CO2) and water** into clean alternative fuels that offer greater grid stability, energy security, and environmental benefits. NREL researchers are working to make these processes more cost effective and commercially viable.
