Since the first flight using sustainable aviation fuel (SAF) took off in 2008, a lot of progress has been made. Below is a snapshot of what is happening in the field of sustainable aviation fuel today.

Regular sustainable aviation fuel (SAF) supply is currently available at Oslo, Los Angeles, Stockholm and Bergen airports. Brisbane and Geneva airports have announced they will join them in the next year.


While the use of sustainable aviation fuel is still relatively low compared to traditional jet fuel, a number of airlines have shown real leadership in driving the use of SAF forward by signing significant forward purchase agreements. These do not include the many airlines that have undertaken one-off or multiple SAF flights. This page has a list of all those special passenger flights from 2011 when the fuel was certified for commercial use.

Sustainable aviation fuel can now be made through five different processes, all internationally approved. It is expected that more of these ‘pathways’ will be approved in the coming years.

Pathways and processes Feedstock options Producers using the pathway Date of Approval Current blending Limit
Fischer-Tropsch Synthetic Paraffinic Kerosene (FT-SPK) biomass (forestry residues, grasses, municipal solid waste)   2009 up to 50%
Hydroprocessed Esters and Fatty Acids (HEFA-SPK) algae, jatropha, camelina Alt Air 2011 up to 50%
Hydroprocessed Fermented Sugars to Synthetic Isoparaffins (HFS-SIP) microbial conversion of sugars to hydrocarbon Amyris 2014

up to 10%

FT-SPK with aromatics (FT-SPK/A) renewable biomass such as municipal solid waste, agricultural wastes and forestry residues, wood and energy crops   2015 up to 50%
Alcohol-to-Jet Synthetic Paraffinic Kerosene (ATJ-SPK) agricultural waste products (stover, grasses, forestry slash, crop straws)   2016 up to 30%
