Sustainable aviation fuel

We recognise that air travel is currently not environmentally sustainable given the fuel sources currently used to fly our aircraft. One of the ways we can reduce the impact of our flying is to increasingly use lower carbon, non-fossil derived fuel.

About sustainable aviation fuel

This collection of non-conventional fuels - which utilise different biogenic and non-biogenic feedstocks and processing technologies – is known by the umbrella industry term 'sustainable aviation fuel' or 'SAF'.  In contrast to some zero emission technologies such as hydrogen powered and battery powered aircraft, SAFs are a technological solution that are available now, and can be transported through existing liquid fuel supply chains. Currently SAFs have to be blended with conventional jet fuel (typically at 30% - 40% blend rates) in order to be a 'drop in' solution for existing aircraft, but the industry is moving towards using 100% SAF blends (which we expect to occur in the second half of this decade).  

As an end of the line, predominantly long haul carrier, most of our emissions arise from our international network (where SAF is the central solution given the expected range constraints of other zero emission technologies in the short to medium term). We also pick up approximately 70% of our current conventional jet fuel from Australia. So that is why we’re collaborating to help accelerate the development of a sustainable aviation fuel (SAF) industry in Australia so that we can have better access to lower emissions fuels in the future. 

Achieving our net zero emissions goal

The use of sustainable aviation fuel (SAF) is one of the central levers to achieving our net zero by 2050 target. With long-haul routes accounting for the majority of the Group's emissions profile, SAF is currently the only viable technology/decarbonisation option available for Qantas' long-haul flights.

Currently, SAF comprises 0.2% of our fuel use and is being accessed by Qantas for our Heathrow flights. Our target is for 10% of our fuel use to come from SAF by 2030 (around 600ML of unblended SAF a year) and approximately 60% by 2050.

The use of SAF is currently modest but in line with current industry production outputs, and is increasing globally - particularly in Europe, the UK, and the US - as governments and industry work together to find ways to reduce the environmental impact of the aviation sector. We need to see this type of collaboration in Australia.

Developing a domestic SAF industry

Qantas has a number of initiatives in train to help kickstart a domestic SAF industry, including our $400 million Climate Fund, and Corporate SAF program.

The Group is part of the Federal Government’s Jet Zero Council and continues to advocate for a SAF blending mandate as part of a broader framework of industry policies such as supply side subsidies, grants and credits, similar to those already announced in other jurisdictions. 

To support this, the Group engaged ICF International, in partnership with Airbus, to model a policy roadmap for Australia. The Developing a SAF industry to decarbonise Australian aviation report (PDF) recommends the government:

  • Implement a SAF mandate.
  • Deploy $1.5 billion in capital grants and production incentives tied to carbon emission reduction. 

This policy suite, if successful in catalysing a domestic low carbon fuel sector, has the potential to contribute over $12 billion to the economy by 2040 creating or sustaining over 70,000 jobs.

As part of the 2024-2025 Federal Budget, several measures were introduced to support the development of a domestic low carbon fuel sector, including elevating low carbon fuel into one of the prioritised sectors with potential access to the $1.7bn Future Made in Australia Innovation Fund. 

What is sustainable aviation fuel?

Did you know that used cooking oil can help to power the engines of some of our planes? Find out how sustainable aviation fuel is produced and the role it can play in helping achieve our emissions reduction targets.

SAF is non-conventionally derived aviation fuel that is made by blending traditional fossil derived jet fuel with fuels made from sustainable biogenic and non-biogenic sources. These include not just cooking oils, but also council waste, plant oils, agricultural residues and non-biological sources such as green hydrogen, renewable electricity and CO2.

Biogenic SAF has the potential to reduce emissions on a lifecycle basis, typically by up to 80% compared with conventional jet fuel. Non-biogenic SAF or synthetic fuel is a pathway which utilises carbon dioxide, hydrogen and significant amounts of renewable electricity to synthesise a liquid fuel with favourable sustainability characteristics (emissions can be reduced on a lifecycle basis by up to 90% compared to fossil fuels).

It is important to note that SAFs do not eliminate the CO2 emissions at the point of combustion – there are still emissions out of the 'tail pipe'. The emission reduction occurs upstream as a result of the method in which the SAF is produced. These are known as lifecycle emissions.

For example, for SAFs produced from oil seeds, the plants absorb CO2 and act as a 'carbon sink' during their growth phase. When a lifecycle analysis is conducted, the emission reduction attributed to the biogenic feedstock production result in typically around 80% less CO2 when compared with fossil jet fuel. A SAFs emission reduction and sustainability credentials are certified by a number of independent, global bodies. The overall emission reduction of the SAF used in an aircraft will also be impacted by the blending rate. 

In addition to the reduction of total life cycle CO2 emissions, the combustion of SAF typically produces very low levels of sulphur and can reduce the emission of particulate matter by up to 90%, compared with conventional jet fuel. Reducing these emissions can improve local air quality, particularly in areas with a high density of flight movements, such as airports.

Accessing sustainable aviation fuel

At an industry level, the primary challenge with SAF is scaling it to the level required for  airlines to meet their ambitious usage targets. The International Air Transport Association (IATA) recently noted that there was a tripling of global SAF production in 2024 but that this still only represented 0.53% of the global airline fuel consumption.

IATA further estimated that over the whole transition period (2024-2050), the global transition cost for the aviation industry could reach US$4.7 trillion (with SAF transition being the majority of the that cost); and between approximately 3000 - 6000 new SAF refineries would be required globally.

The development of SAF is therefore best viewed as not just a transportation issue, but as part of the challenge of transitioning a global energy system. Given early production constraints, SAF currently comprises only a small amount of our fuel use, as it is not yet commercially available in Australia. However, we purchase SAF for some of our flights out of London and we have plans to expand this usage over time, including at our US ports. For the SAF we acquire in Heathrow, the SAF is delivered into common user fuel infrastructure rather than directly into our aircraft.

Watch the video to learn from our team about our goals, including how we're supporting the establishment of a SAF industry in Australia.

  • In December 2021, Qantas became the first Australian airline to purchase SAF on an ongoing basis, which is being delivered at London Heathrow Airport.
  • As part of the Group's widebody renewal program with both Airbus and Boeing, Qantas has contractually secured access rights to SAF volume from a number of projects (including in the USA) that, subject to reaching a final investment decision, aim to commence producing SAF prior to 2030.    

If these US projects proceed, we anticipate that the SAF volume that the Group can procure from these projects will enable us to meet the majority of the Group's interim SAF target for 2030.

How can SAF help in reducing emissions?

1. Certified Sustainable Feedstock including wastes and residues such as cooking oil and council waste.

Most materials on Earth are carbon-based including jet fuel. Sustainable feedstocks include wastes for which the carbon has already been accounted in the use of the primary product or has been absorbed from the atmosphere in its production.

recycle

2. Sustainable feedstock converted into sustainable jet fuel.

Sustainable feedstocks are broken down through chemical processing before being built back up into a long chain hydro-carbon – making a sustainable jet fuel.

oil drop

3. Sustainable jet fuel is blended up to 50/50 with fossil jet fuel.

The sustainable jet fuel is blended up to 50% with fossil jet fuel and tested to ensure it meets the requirements of the American Society for Testing and Materials for aviation fuel.

4. Blended sustainable aviation fuel delivered into airport fuel farm.

The certified SAF, which is now considered chemically equivalent to jet fuel, is then delivered to the shared re-fuelling infrastructure at airports and into fuel farm at the airport.

SAF Coalition Program

Qantaslink A220

Our program supports the development of an Australian SAF industry by providing a strong corporate demand signal for SAF derived emission reduction, while also helping corporations to take steps to lower business travel emissions that arise from their employees travelling by air.

As a member of the Qantas SAF Coalition, participating corporations contribute to the incremental cost of SAF being purchased by Qantas, initially out of Heathrow. As a member, corporates are allocated a volume of scope 3 emission reductions associated with a parcel of SAF the cost of which they have contributed to.

These partnerships are crucial to making SAF affordable, which can be several times more expensive than traditional jet fuel, and in turn assist in the scaling of the SAF industry to meet the airline industry's SAF usage targets.
