Imagine climbing aboard your favorite jet to jet off to your holiday destination, but instead of the roar of the jet engines, you hear the quiet whirr of an electric motor. Now imagine that your flight lands safely, and as you disembark, you don’t hear the normal hustle and bustle of people rushing off the plane, but instead notice that everyone waiting to board with you is taking their time to use their electric cars provided by the airport on-site charging station. These changes may be coming sooner than we think, thanks to the rise of sustainable aviation fuels! What are sustainable aviation fuels?

Background: Why Should I Care?

Sustainable aviation fuels (SAF) are a promising solution to reducing emissions from the aviation sector, which is one of the fastest-growing sources of greenhouse gas emissions. SAFs can reduce emissions by up to 80% compared to traditional jet fuel, and they have the potential to be a truly sustainable fuel source if produced from renewable energy sources.

How Did We Get Here?

The aviation industry has been searching for a way to reduce its environmental impact for many years. Jet fuel, which is derived from crude oil, is a major source of greenhouse gas emissions from airplanes. In an effort to reduce these emissions, the aviation industry has turned to sustainable aviation fuels (SAF).

What Are Some Examples?

1. Sustainable aviation fuels (SAF) are derived from renewable sources and have a lower carbon footprint than traditional jet fuels. 

2. The global SAF market is expected to grow from $2.8 billion in 2020 to $14 billion by 2030, according to a report by MarketsandMarkets. 

3. The use of SAF could help airlines meet their climate goals and save money on fuel costs.

What Is The Biggest Roadblock?

The biggest roadblock to the growth of the sustainable aviation fuel industry is the lack of infrastructure. There are only a handful of airports that have the necessary facilities to produce and distribute sustainable aviation fuels. This lack of infrastructure limits the ability of airlines and other fuel users to access sustainable aviation fuels.

How Can We Solve This Problem?

The global commercial aviation industry emits around 940 million metric tons of CO2 each year, accounting for 2-3% of all man-made emissions. The rise of sustainable aviation fuels (SAF) presents a unique opportunity to reduce these emissions while also supporting economic growth. SAF is made from renewable sources such as plants and waste oils, and they can achieve up to 80% reduction in carbon emissions compared to traditional jet fuel.

A few companies have a large market share in this space. However, we are expecting many new entrants in the coming years. This is due to the increasing awareness of environmental issues and the desire to be more sustainable. The increased competition will likely lead to lower prices and more innovation in the space.

Announcing their sustainable aviation fuel (SAF) program early this summer, American Express Global Business Travel (Amex GBT) and Shell Aviation urged the private sector to contribute to the decarbonization of air travel. Participants will have access to one million gallons of SAF at the program start and can use the novel book-and-claim solution powered by blockchain.

With the help of the Energy Web Foundation, the energy company Shell and the professional services provider Accenture created the blockchain solution called Avelia (EWF). Avelia offers clients trackable and verified reports of emissions avoided through buying SAF on the platform. Other blockchain solutions promoting sustainability include Melanin Solar and Nyukia.

What Kind of Impact Could This Technology Have on Air Travel & Tourism?

The airline industry is one of the largest contributors to global warming, emitting around 940 million tons of CO2 yearly. But there’s hope on the horizon in sustainable aviation fuels (SAF). These cleaner-burning fuels have the potential to reduce emissions by up to 80%, and the market for them is expected to grow significantly in the next decade. As they become more popular, travelers expect a decrease in prices. 

Airlines are also interested in SAFs because they’re cheaper than other options like renewable jet fuel or biofuels. It’s no surprise that many airlines are already investing heavily in this emerging technology – SAS Group has been working with Rolls Royce to develop their own SAF that could power 50% of their fleet by 2030.


Investing in alternative fuel sources for aviation has extraordinary potential to transform all flights, from domestic to abroad. The aviation industry has been working diligently to reduce its environmental impact for many years. In recent years, the focus has shifted to developing alternative fuels that can help power flights without producing as much pollution. Sustainable aviation fuels (SAF) are a promising option, and the industry is expected to invest billions of dollars in them over the next decade.
