Sustainable Aviation Fuel Companies: 8 Top Picks for 2024 and Beyond

Do you worry about the probable environmental impact of flying? Amid the many requirements of reducing carbon footprints linked with flying, there is an upward demand by companies dealing with sustainable aviation fuels.

With so much choice, knowing who is leading the field in such a critical endeavor can be somewhat overwhelming.

For that reason, the article briefly focuses on 8 leading companies dealing with sustainable aviation fuel that you simply have to know.

From pioneering start-ups to major companies, we look at the frontier of technologies in sustainable aviation to help you make an informed and green choice for your future air travel.

Let’s get started.

What’s Sustainable Aviation Fuels (SAF)?

Before getting to the leading sustainable aviation companies, it’s better to understand them in detail.

Sustainable Aviation Fuels (SAF) are biofuels produced to reduce aviation carbon emissions. It does not compete in food crops or the causes of deforestation, produced from sustainable resources like waste oils, fats, greases, and agricultural residues.

SAF reduces carbon dioxide up to 80% in its lifecycle compared to conventional jet fuel. It is mainly capable because the biomass used as feedstock absorbs CO2 during its growth, which is the synthesis of emissions from fuel use in aircraft.

Watch this video by Financial Times to learn more about sustainable aviation fuels:

The International Civil Aviation Organization has, on its part, identified SAF as the fuel that offers airlines the greatest opportunity in proportion to their capacities to assist with aviation in reducing CO2.

This will be supported by various policies and goals, including the long-term aspirational goal of net-zero carbon emissions that will be achieved by 2050, as set by the ICAO, per the temperature goal of the UNFCCC Paris Agreement.

The production, consumption, and use of SAF are based on globally recognized sustainability criteria and life cycle methodologies, optimizing environmental life benefits.

Now, let’s discuss how refueling EU aviation and IRA influence SAF.

How Refuel EU Aviation and IRA Influence SAF?

Key legislation concerning SAF in the European Union and the United States include the Refuel EU Aviation initiative and the Inflation Reduction Act (IRA).

Refuel EU Aviation aims to make air travel greener by increasing the use of SAF. It sets SAF use at 2% by 2025 and 6% by 2030, with the biggest goal of 70% use by 2050. It also encourages airlines to refuel mostly in the EU’s airports to be efficient in cutting down on unnecessary weight and emissions.

In the U.S., financial aid is through tax credits, whereby SAF is allowed to reduce the price of its fuel by a certain credit for every gallon used in flying, reducing greenhouse gas emissions by at least 50% from ordinary jet fuel.

The credit starts at $1.25 per gallon and goes up as emissions decrease, maxing out at $1.75 per gallon. The International Renewable Energy Agency (IRENA) has proposed extending the tax credit for the production of Sustainable Aviation Fuel (SAF) from 2023 to 2027. The objective of this proposal is to aid the production of 3 billion gallons of SAF by the year 2030. The European Union (EU) and the United States (U.S.) are also committed to promoting eco-friendly air travel and have established clear targets and financial incentives to encourage the growth of SAF.

It is very important to do so because it will greatly reduce pollution from air travel and fight climate change on our planet. If everyone chips in together, big strides can be made in producing and using SAF, helping to reach the global sustainability goal and targets set in the Paris Agreement.

Let’s discuss the top 8 leading sustainable aviation fuel companies in detail.

Neste Homepage

Neste employs a process called hydrotreating to produce sustainable aviation fuel. In this process, renewable waste and residue raw materials are first refined to remove impurities and contaminants.

The refined feedstock then undergoes hydroprocessing, where it is treated with hydrogen under high temperature and pressure conditions. This process breaks down the feedstock into smaller hydrocarbon molecules, further refined to meet aviation fuel specifications.

The resulting sustainable aviation fuel is compatible with existing aircraft and infrastructure, offering a low-carbon alternative to conventional jet fuel.

Neste produces a range of renewable fuels, including renewable diesel, renewable jet fuel, and renewable chemicals. Their sustainable aviation fuel, branded as Neste MY Sustainable Aviation Fuel, is derived from renewable waste and residue raw materials.

These raw materials can include used cooking oil, animal fats, and waste oils from food processing industries.
