Sustainable Aviation Fuel (SAF) reduces lifecycle CO2 emissions by at least 80% compared to fossil jet fuel. After flying less, SAF is the best solution to prevent new CO2 from entering the atmosphere from burning fossil fuels. With Fly on SAF, you can reduce your carbon footprint by replacing fossil fuel with SAF. Insert your travel itinerary and check out the possibilities.
Environmental impact
What is the environmental impact of flying?
Currently, aviation is responsible for about 3% of CO2 (carbon dioxide) emissions. CO2 is a greenhouse gas that warms the temperature of the Earth and contributes to climate change. 3% may seem low, but as countries become wealthier, more and more people are choosing to fly. In fact, it’s predicted that aviation could consume 25% of the global carbon budget by 2050. The carbon budget is the amount of CO2 we can emit and still stay within the 1.5°C scenario, set by the Paris Agreement. Furthermore, aircraft emissions are released high in the atmosphere, which means they have a more potent impact on climate change.
What can I do to reduce the environmental impact when I fly?
The most effective way to act more sustainably is not to fly at all. Limiting your air travel by choosing other greener modes of transport is another option. However, when flying is essential, there is a solution available to reduce your carbon emissions. How? By choosing SAF (Sustainable Aviation Fuel). SAF is a renewable alternative to fossil jet fuel that can reduce the lifecycle emissions of fuel by at least 80%. With our Fly on SAF tool, you can choose how much SAF you would like to purchase to reduce your emissions. Changing your air travel habits can also make a difference. Some ideas are:
→ Travel as lightly as possible.
→ Fly economy rather than business class or first class (less space and weight).
→ Another excellent way of reducing your environmental impact: recommend SAF to your friends!
What action is the aviation industry taking?
It’s in the best interests of the industry to make flying more sustainable. That’s why they’re investing in cleaner aircrafts, more efficient operations, and SAF (Sustainable Aviation Fuel). While SAF mandates are coming to many countries from 2025 onwards, currently, it’s voluntary whether travelers, businesses and most airlines buy SAF to reduce their carbon footprint. We believe that all actors – producers, fuel suppliers, airlines, individuals and governments need to act to ensure that we reach climate goals set by the UN for 2030 and beyond.
How are my flight’s CO2 emissions calculated?
Carbon emission calculations follow the International Air Transport Association (IATA) Recommended Practice - RP 1726, and take into account parameters such as all scheduled flights, aircraft fuel consumption, seat configuration, and historical load factors from more than 400 airlines (precision of the calculation depends on the input data).
Why are my emissions higher if I travel in business or first class?
Business and first-class seats are generally heavier and take up more room. This means the carbon emissions attributable to you will be higher than traveling in economy.
Sustainable Aviation Fuel (SAF)
What is SAF?
SAF (Sustainable Aviation Fuel) is a substitute for fossil fuel. It is produced from sustainable resources, like agricultural or biomass waste and used cooking oils. SAF is known as a “drop-in” fuel because no changes need to be made to the aircraft or the infrastructure. Compared to fossil fuel, SAF can reduce carbon emissions by at least 80%, which will significantly lower the industry’s carbon footprint and dependency on fossil fuel.

What are the benefits of SAF compared to fossil jet fuel?
80% fewer emissions compared to fossil jet fuel is a pretty significant benefit. The emissions reductions are calculated across the life cycle of the SAF, including emissions from production, distribution, transportation and combustion. Other emissions, like particulates and sulphur are reduced by 90% and 100% respectively while using SAF. Using This means the use of SAF will instantly lead to cleaner air. It’s as simple as that also leads to less air pollution.
What is SAF made from?
SAF can be produced from a variety of sustainable resources, also known as feedstocks. This includes agricultural waste, used cooking oil, and industrial waste. We are also looking at forestry residues and non-biobased carbon as promising feedstocks for the future. SkyNRG does not allow the use of food crops, like soy and palm oil. These can be responsible for high rates of deforestation.
Is SAF the same as biofuel or synthetic fuel?
It all depends on what it’s made from. When it’s made from bio-based material, like used cooking oil, it can be called a biofuel. However, it can also be produced from CO2 captured from the air, which isn’t bio-based. Then it’s called synthetic fuel.
Is it safe to fly on SAF?
Absolutely. SAF meets exactly the same quality and safety requirements as fossil jet fuel. Over 450-600,000 flights have already been flown using SAF.
How do you guarantee that SAF is sustainable?
Our operations have been certified by the Roundtable on Sustainable Biomaterials (RSB), which is a worldwide initiative. Bringing together farmers, corporations, NGOs, experts, governments, and inter-governmental agencies concerned with ensuring the sustainability of biomass production. RSB is widely accepted as the “gold standard” of voluntary certification schemes. RSB certifies the operations of SkyNRG to ensure we are acting within the sustainability guidelines for the part of the SAF supply chain that we have ownership over. Feedstocks don't necessarily have a certification, but need to comply with regulations, e.g., which are eligible to make SAF from, and we have our own independent Sustainability Board who needs to approve all feedstocks related to our SAF sourcing. SkyNRG and our Sustainability Board have also set stringent sustainability requirements for the SAF that we procure.
How are my flight’s carbon emissions reduced by flying on SAF?
Even when flying on SAF, an aircraft engine still emits CO2. However, the sustainable resources used to produce SAF recycle the CO2 emitted previously. It’s the short time needed to recycle carbon emissions that makes the biggest difference.
Can SAF reduce my flight’s carbon emissions by 100%?
Yes. SAF can reduce the CO2 emissions from your flight by as much as you want. If you choose to replace the fossil jet fuel from your flight with the same amount of SAF, the carbon reduction will be around 80-85%. If you choose to replace more than the fossil jet fuel from your flight with SAF, you can reduce your carbon emissions by a 100%.
What does the market for SAF look like?
The SAF market is relatively small. The primary challenge lies in the is limited worldwide production capacity. Expanding production of SAF is key. This is why SkyNRG is in the process of constructing the first specialized SAF facility in Europe, located in the Netherlands. The current limited production makes SAF more expensive than traditional fuels. In the past, the price differential used to be as high as 15 times more expensive, but it has since reduced to a range of three to six times the cost of conventional jet fuel.
Payments and tracking
What happens with my financial contribution?
Almost all the money contributed goes to the procurement of SAF. We charge a small, fixed fee per transaction to build, manage and improve this platform. Your SAF contribution will be used by SkyNRG to deliver SAF in the coming months on a so-called ”Book and Claim” basis, a widely used system when SAF is not actually supplied to the aircraft of the person who made the contribution, but delivered to the fuel system of an airport close to the SAF production facility. The SAF is then tracked, verified and the carbon emission reduction is “booked” to the person that paid the contribution. That person can “claim” the carbon reduction. This has two important advantages:
1) Supplying SAF to the nearest airport minimizes carbon emissions and costs in the supply chain.
2) It is airline and location independent, as it allows air travelers to buy SAF based on their total aviation footprint in one transaction, rather than buying through each airline individually.
What do I pay for when I purchase SAF?
You pay for the CO2 reduction impact of SAF. SAF significantly reduces CO2 emissions compared to fossil fuel, but it is more expensive. This price difference is paid by you and an airline, so the total costs are shared and lower for everyone. As a result, you and an airline reduce your footprints at the same time.
Can I contribute to SAF whenever I want?
You certainly can. It doesn’t matter when you fly or who you fly with. All you have to do is enter your flight details in our Fly on SAF tool and we will take care of the rest.
Can I reduce my CO2 emissions from past flights?
Yes, you can reduce as many past flights as you want.
As a corporate traveler, is it possible to receive an impact certificate for my company’s Scope 3 GHG emission reduction reporting?
For orders over 10mt CO2e, please forward the invoice from your purchase (check your e-mail inbox) to info@flyonsaf.com, add your request and company name to the email and we will get back to you.
