Why it's on ClimateTicker

LanzaJet operates the first commercial-scale US ethanol-to-jet (ETJ) SAF facility, which can deliver meaningful lifecycle emissions reductions versus fossil jet fuel — but the actual climate benefit is highly feedstock-dependent. When corn-based ethanol is used, emissions reductions shrink or can be offset by indirect land-use change; the genuine climate case rests on scaling low-carbon or waste-derived feedstocks, which remain a fraction of current supply.

mitigationLanzaJet licenses its patented alcohol-to-jet technology and operates the Freedom Pines Fuels facility in Georgia, selling SAF and renewable diesel to airlines and fuel buyers, while generating revenue from technology licensing deals for future third-party plants.

Controversy & Greenwashing Watch

mediumFeedstock carbon accounting dispute

Independent researchers and analysts warn that corn- and sugarcane-based ethanol feedstocks can increase net aviation emissions when indirect land-use change (e.g., deforestation to grow energy crops) is fully counted, a risk LanzaJet has not publicly addressed with transparent, third-party-verified LCA data specific to its Georgia plant.source ↗

lowFossil inputs in ATJ process

The alcohol-to-jet conversion process at Freedom Pines uses grid electricity, fossil natural gas, and hydrogen predominantly derived from fossil gas, partially undermining the renewable claim unless these inputs are decarbonized.source ↗
