What is CO₂?

CO₂ (or carbon dioxide) is a natural gas in Earth’s atmosphere. It is the main contributor to global warming and is released by the burning of fossil fuels during human activities, such as flying. In aviation, CO₂ is the most well-known greenhouse gas, but aircraft also emit non-CO₂ substances, which play a role in the sector’s overall climate impact.

How is the CO₂ estimation calculated?

The emissions displayed in the bookingflow are estimated based on historical data on a yearly average of all of Transavia’s direct flights on the selected route. We make a calculation for every flight route based on aircraft type, load factor, fuel use. The calculator is audited yearly.

What is Sustainable Aviation Fuel (SAF)?

Air travel is currently not sustainable. Your contribution to SAF (an alternative to regular aviation fuel) will help to slightly reduce air travel’s dependency on fossil fuels. SAF stands for 'Sustainable Aviation Fuel', which is the name our industry uses to describe a better alternative to regular aviation fuel.

Using SAF instead of regular fuel is better* because:

  • It’s made from non-fossil resources, such as used cooking oil. 
  • Although SAF emits the same amount of CO₂ during the flight, its CO₂ impact is at least 65% lower over the entire lifecycle (from production to burning). 
  • It reduce other harmful emissions as fine particles and sulfur.
* Transavia only selects SAF that meets the sustainability criteria set by the European Union as defined by the ReFuelEU Aviation Regulation.

 

How do we use SAF?

SAF is mixed with regular fuel in the airport fuel tanks to refuel our and other planes. This means we cannot guarantee that SAF will be used on your specific flight. But your contribution does help to slightly reduce the CO₂ impact of a future flight. 

The SAF we select meets the strict European regulations, such as:

  • A minimum 65% reduction in CO₂ lifecycle emissions compared to fossil

  • It doesn’t compete with food chains or lead to deforestation.

We follow these conditions for all SAF we purchase worldwide.

Starting in 2025 and continuing through 2030, European regulations will require all fuel suppliers to include 2% SAF in their fuel deliveries to European airports.

How your contribution will help

SAF production is still very limited, making it more expensive than regular jet fuel. If you contribute to this option, we’ll use it entirely to buy SAF. We aim to purchase the extra SAF within 12 months of your flight.

Contributing to SAF?

While booking your flight, you can choose to contribute to SAF. We estimate how much fuel is needed per passenger for the selected flight. The SAF you buy won’t directly replace the regular fuel on your flight. However, it will allow us to buy a bit more SAF to add to the airport's fuel system.
