Contribute to sustainable aviation fuel

Join us in reducing air travel’s dependency on fossil fuels

Aviation accounts for around 2.5% of global CO₂ emissions. In addition to CO₂, flying generates other emissions that can contribute to global warming, especially at high altitudes.

Sustainable aviation fuel (SAF) is an alternative to fossil kerosene that can help reduce the industry’s reliance on fossil fuels. Produced from non-fossil resources, such as used cooking oil, SAF has a significantly lower carbon impact than fossil-based kerosene when assessed over its entire life cycle.

When burned, sustainable aviation fuel produces about the same amount of carbon dioxide as fossil fuel. The difference arises from the fact that SAF is made from renewable raw materials. In this way, the carbon released from the fuel is part of the natural cycle and does not increase the CO₂ concentration in the atmosphere in the same way as fossil fuels.

Although SAF is a positive step forward, its use in aviation remains limited due to high costs and low availability. As a result, its current impact on the aviation sector’s carbon footprint is still modest. That is why scaling up the use and production of SAF is a shared goal for everyone working to reduce aviation’s dependency on fossil fuels.

Contribute to SAF while booking your flights

When booking your next flight on our website or through the app, you have the possibility to contribute to SAF. The contribution amount is €3–15 per passenger per direction. It's predefined and based on the travel class and the length of the Finnair-operated flights in your booking.

Finnair only purchases SAF made from raw materials that do not compete with food production or harm biodiversity. All the SAF we use meets the strict sustainability criteria set by the ReFuelEU Aviation Regulation, the EU’s Renewable Energy Directive (RED) or CORSIA. For example, biofuels that comply with EU regulations must reduce CO₂ emissions by at least 65%.

While each individual contribution has a modest impact, we believe that every step matters in advancing the use and production of SAF.

Finnair for Business and Finnair Cargo customers can also participate:

SAF contribution for Cargo customers

Your full contribution is invested in the sustainable aviation fuel (SAF) that comes on top of all the rest of the SAF we buy ourselves. We do not use your contribution to cover the mandated SAF costs for Finnair.
The price of SAF is currently 2–3 times higher than that of conventional kerosene. When we procure SAF, your contribution is used to cover only the price difference. For example, if SAF costs €3,000 per ton and conventional kerosene €1,500 per ton, the difference is €1,500 per ton.
Your contribution does not directly increase the amount of SAF used on your specific flight or reduce CO₂ emissions from that journey. Instead, your support helps reduce the overall environmental impact of aviation.
SAF is not physically delivered to a particular aircraft. Instead, it's blended with conventional jet fuel and distributed through the airport’s shared fuel system.
The SAF purchased with customer contributions meets the sustainability criteria defined in the Refuel EU Aviation regulation.

Follow the progress

We are committed to increasing our SAF usage. The share of SAF in our fuel mix will grow through both regulatory mandates and voluntary actions.

The EU mandates fuel providers to mix on average 2% of SAF for flights departing from the EU. Any additional SAF we purchase will be in addition to this mandated amount.

Finnair’s total SAF usage

In 2025, approximately 1.6% of our total jet fuel purchases were SAF. This includes the mandated SAF, contributions from individual customers and voluntary SAF purchases funded by Finnair and our corporate partners. As we fuel our aircraft also outside the EU, the percentage reflects the share of SAF in relation to our global fuel consumption.

Customers’ SAF contributions so far

Since November 2024, our customers have been able to contribute to SAF purchases when booking their flights online. One contribution includes the SAF purchase for a one-way flight.

At the end of 2025, around 114,000 customers had chosen this option, and we were able to purchase a total of about 280 tonnes of SAF with their inputs. This amount corresponds to the amount of fossil fuel used for approximately 140 flights between Helsinki and Oulu.

As the service was launched in November 2024, our first reporting period covers contributions from the start of the service until the end of December 2025. Going forward, we invest our customers’ contributions in SAF twice a year and report on the progress in the same time frame.

Finnair for Business and Cargo customers can contribute to SAF purchases through separate services. Their contributions are not included in the above purchase.

SAF funded by public authorities

Finnair applies for allowances to cover part of the price difference between fossil kerosene and the eligible sustainable aviation fuels. The allowances are issued by The Finnish Trasport and Communication Agency (Traficom).

In 2025, Finnair applied for EU ETS emission allowances based on the 4,688 tonnes of SAF it used in 2024, of which 769 tonnes were consumed on EU ETS‑covered flights. As a result, Finnair received 6,810 emission allowances. This means that Finnair’s eligible SAF use in 2024 was partially co‑funded through the EU Emissions Trading System, providing 0.47 million euros in support.
