Round up for the future
Every contribution supports a more sustainable aviation industry: With “Round up for the future”, you can voluntarily round up the total price of your Condor or Marabu flight. You can choose to round up directly when booking your flight and play a part in making aviation more sustainable. The difference will be fully invested in using more Sustainable Aviation Fuel (SAF) in future, beyond what is already required by law.
How it works
- 1. Book your flight: After entering the flight and passenger details, you'll be taken directly to the payment overview.
- 2. Check the box: Confirm with one click that you'd like to help promote the use of Sustainable Aviation Fuel (SAF).
- 3. Round up the amount: Then choose if you want to round up the final price to the nearest US$ 10, US$ 20, US$ 50, or US$ 100 / CA$ 10, CA$ 20, CA$ 50, or CA$ 100. The difference will be displayed to you at this point.
- 4. You've done your bit to promote more sustainable aviation: The rounded-up amount will be fully invested in expanding our use of SAF to refuel Condor aircraft over the next 12 months.
How we use SAF at Condor
What is Sustainable Aviation Fuel (SAF)?
Sustainable Aviation Fuel (SAF) is an umbrella term for all aviation fuels that are produced without the use of fossil fuels like petroleum, which have an up to 80 % lower carbon footprint. For electricity-based power-to-liquid (PtL) fuels, the CO₂ reduction compared to fossil fuel-based kerosene will be even higher in the future (> 90 %). SAFs are blended with conventional fossil kerosene for use in aviation.
And why is it important?
Alternative fuels are the only way to decarbonize aviation with existing technology. Condor will purchase SAF over the next 12 months as part of “Round up for the future” in quantities that exceed the legally prescribed amounts. This amount of SAF will be used on future Condor flights. Moreover, according to the German Aerospace Center (DLR), Sustainable Aviation Fuel (SAF) can help reduce contrails and climate impacts in air travel.
Because SAF contains fewer aromatic compounds than kerosene, it results in fewer soot particles. This reduces the formation of ice crystals and thus the development of cirrus clouds, which contribute to global warming. Moreover, SAF could positively impact other non-CO₂ emissions like nitrogen oxides and continue to alleviate the pressure on the climate.
How can you support us in using SAF in the future?
Your contribution makes a difference – when refueling on future Condor flights. We specifically use the rounded-up amount from the “Round up for the future” initiative to purchase and use Sustainable Aviation Fuel (SAF). The funds are allocated exclusively to SAF fuel. Book now, round up, and together we will make a big difference, little by little!
Overview of Condor's engagement in Sustainable Aviation Fuel (SAF)
We are also committed to other initiatives that support the market expansion of SAF and PtL (electricity-based).
Supply agreement with Neste – going beyond regulatory requirements
Neste is market leader in SAF production and delivers the best possible quality and supply capabilities. Condor and Neste have engaged into a multi-year supply agreement ReFuelEU Aviation 2 % SAF mandate as well for a specific voluntary amount beyond the mandate.
Partnership with Caphenia for power-based sustainable fuels
Condor and start-up Caphenia have engaged into a long-term partnership on the use of Sustainable Aviation Fuels (SAF). In doing so, we are supporting the further development of the process to market-readiness, while ensuring access to firmly agreed purchase quantities once production has reached an industrial scale. (expected to be in 2027).
Caphenia aims to generate a synthesis gas from bio-methane, CO₂, water, and renewable energy to produce environmentally friendly fuels. According to Caphenia, CO₂ emissions can be reduced by up to 92 % compared to the fossil fuel kerosene.
Caphenia's first production facility is currently being built at the Höchst Industrial Park in Frankfurt to demonstrate the industrial scalability of the technology. It is expected to start producing SAF on an industrial scale from 2027, at which point the purchase agreement with Condor will also take effect.
Involvement in the German Government's SAF working group
Since 2024, we have been a member of the “Climate Neutral Aviation Working Group steering committee (AKKL)” and actively take part in the SAF working group. We are also involved in researching and testing the operational avoidance of contrails, as part of the 100-flight trial by AKKL. This experiment offers valuable insights into how climate-impacting contrails are formed and prevented.
Associated partner of the innovation platform InnoFuels
This project is coordinated by the Karlsruhe Institute of Technology (KIT) and runs from February 2023 to August 2026. The goal of the InnoFuels platform is to speed up the industrial production of electricity-based fuels (power-to-liquid, or PtL) and advanced biofuels in Germany. This will be achieved by connecting stakeholders from science, industry, politics, and society to leverage synergies and advance the development and application of these fuels.
The project is divided into seven thematic innovation priorities, which encompass all process steps – from raw material procurement through production to the application of fuels. In these areas, research institutions, companies, and political actors collaborate to develop practical solutions. We are also involved in the steering committee for the aviation sector.
Collaboration with INERATEC
The first commercial-scale INERATEC plant is located in Frankfurt, designed to produce up to 2,500 tons of sustainable e-fuels and e-waxes annually. Located in an industrial park, the plant uses renewable hydrogen and biogenic CO₂ to produce synthetic hydrocarbons that are then processed into drop-in fuels, waxes, and chemicals. These products are compatible with existing infrastructure and will meet the legal requirements for sustainable fuels in various industries, including aviation, shipping, and chemicals.
The INERATEC Customer Advisory Board (CAB) is an exclusive, invitation-only forum for leading representatives of airlines, aircraft manufacturers, airports, and policymakers who are shaping the future of more sustainable aviation. Condor has been involved in CAB since spring 2025.
By providing insights into market trends, production requirements, and regulatory challenges, members help INERATEC scale its e-SAF technology to advance industry-wide decarbonization efforts.

Frequently asked questions
How does Round up for the Future work at Condor?
You can voluntarily round up the total price of your flight during the flight booking process. After entering the flight details and your passenger information, you‘ll see the option on the payment overview. In one click, you can confirm that you want to support the use of sustainable aviation fuel (SAF) – then choose whether you‘d like to round up to the nearest US$ 10, US$ 20, US$ 50, or US$ 100 / CA$ 10, CA$ 20, CA$ 50, or CA$ 100.
Can I choose how much I want to round up?
Yes, you decide if you want to round up the final price of your flight booking to the nearest US$ 10, US$ 20, US$ 50, or US$ 100 / CA$ 10, CA$ 20, CA$ 50, or CA$ 100. The total price will be displayed in your flight booking.
Can I also round up for Marabu flights? And how is the contribution used?
Yes, even when flying with our sister company Marabu, you can choose to voluntarily round up the total price. The rounded-up amount will also be exclusively invested in using more Sustainable Aviation Fuel (SAF) on Condor flights.
What happens to my rounded-up amount if I cancel my flight?
If you want to cancel your flight, the rounded-up amount will still be invested in using more Sustainable Aviation Fuel (SAF) on Condor flights and cannot be refunded
If your flight is canceled by Condor or Marabu, you‘ll get the rounded-up amount back.
What options do I have as a passenger to make the future of aviation more sustainable?
Condor offers several options for passengers to help create a more sustainable aviation future:
- With the Climate Contribution you can choose from one of eight climate packages when booking your flight. By doing so, you’ll be contributing to selected sustainability projects and using more SAF on Condor flights.
- The Green Fare also lets you contribute to additional SAF on Condor flights and certified climate projects with your booking.
- With Round up for the Future, you can voluntarily round up the fare of your Condor or Marabu flight – 100% of the extra amount goes towards using more SAF at Condor.
All contributions are used exclusively for these purposes and are completely voluntary. The SAF bought with these contributions is more than the legally required amounts, allowing you to make a bigger contribution to more sustainable aviation.
