Sustainable aviation fuel (SAF)

Sustainable aviation fuel (SAF) is an alternative to traditional jet fuel produced from renewable or low-carbon sources rather than fossil fuels derived from oil, coal, or natural gas.

SAF is made from alternative feedstocks, such as used cooking oil, plant-based oils, municipal solid waste, industrial waste gases, and agricultural residues.

In travel, it represents one of the most efficient tools the aviation industry has for reducing its environmental impact, as it can dramatically lower greenhouse gas emissions, reduce reliance on petroleum, and help airlines meet their climate targets.

SAF combustion releases fewer harmful pollutants, such as sulfur oxides and particulates, due to lower impurities compared to traditional fossil jet fuel.

The chemical and physical properties of SAF closely match those of traditional jet fuel. Because of this, SAF can be blended with conventional fuel in various proportions, transported through the same supply infrastructure, and used in existing aircraft and engines without any modifications.

SAF is manufactured through alternative refining processes that differ from traditional petroleum-based pathways and also lower overall carbon emissions.
