All of the world’s planes consumed roughly 100 billion gallons of jet gasoline as they crisscrossed the planet in 2024. Solely about 0.5% of it was one thing apart from fossil gasoline. That might quickly change.
Various jet fuels might slash aviation emissions—which have brought about about 4% of worldwide warming so far. These new fuels could be made with supplies like used cooking oils, crop residue, industrial waste, and carbon dioxide captured from the air. Relying on the supply, they will cut back emissions by half or practically eradicate them. And so they can usually be utilized in current planes, which might allow fast local weather progress.
Extra governments at the moment are setting targets or passing laws requiring airways to start utilizing these different fuels (typically known as sustainable aviation fuels, or SAFs). Beginning this yr, different fuels should make up no less than 2% of the gasoline used at airports within the European Union and UK. That mandate will ramp up within the coming a long time, reaching 70% within the EU by 2050.
As we speak, practically all commercially out there different gasoline is made with waste fat, oils, and greases. Montana Renewables just lately acquired a $1.44 billion mortgage dedication from the US Division of Vitality to broaden one facility for such manufacturing. Nonetheless, these supplies stay in restricted provide.
Firms utilizing different applied sciences and inputs are making progress scaling up. LanzaJet opened the primary commercial-scale facility to make jet gasoline from ethanol in early 2024, with a capability of 9 million gallons yearly. Artificial fuels made with carbon dioxide might additional broaden choices for airways, although these fuels aren’t being produced at industrial scale but.

One essential issue for different jet fuels shifting ahead can be price—on common, SAFs in the marketplace in the present day are typically practically thrice dearer than typical jet gasoline. Having extra firms producing extra gasoline ought to assist carry down the worth, although newer fuels might be much more expensive.
