Sustainable Aviation Fuel

Your guide to SAF, the low-carbon alternative to conventional jet fuel that’s helping to transform the airline industry

Sustainable aviation fuel (SAF) – a low-carbon alternative to conventional, petroleum-based jet fuel – is helping the aviation industry lower its carbon footprint.

Here’s what to know about SAF and why it’s key to the future of flying.

How does SAF work?

SAF is produced by converting readily available materials into a drop-in replacement crude oil.

So far, those materials have included mustard seeds and soybeans; non-edible oils, such as used cooking oils, and animal fats.  

Soon, sustainable biomass, such as forest trimmings and crop waste, will also be used to make SAF.

The result is a fuel that’s chemically identical to petroleum-based diesel and can be implemented without changes to aircraft technology.
