SunExpress x SQUAKE COP31 SAF Calculator

Calculate your Sustainable Aviation Fuel contribution

As the world gathers for COP31, SunExpress offers every guest the chance to support the use of Sustainable Aviation Fuel (SAF). Enter your flight details below to see your estimated CO₂e emissions and the corresponding SAF contribution. A solution powered in cooperation between SunExpress and SQUAKE.

Calculate your flights' emissions first

Add every leg of your journey: outbound, return and connections.

Try a sample:

Antalya awaits – with your SAF contribution

Same schedules, same fleet, same fare classes – the SAF amount attributed to your contribution is added into operations at Vienna Airport, regardless of your origin and destination, following a book-and-claim approach. The contribution does not offset the emissions of your booked flight or make it carbon neutral.

Lifecycle GHG emissions

SAF can have lower lifecycle greenhouse-gas emissions than fossil kerosene. The actual reduction depends on feedstock and production pathway; the effect on the overall fuel mix also depends on the blend ratio.

Drop-in

No aircraft changes

SAF blends directly into existing operations.

Documented

Tracked by SQUAKE

The SAF amount attributed to the contribution is documented through SQUAKE. A corresponding proof is provided for the contribution.
