Flightnook offers every passenger, no matter the airline, a way to make a direct impact.

Cleaner jet fuel is the fastest way to make flight cleaner. It exists today and cuts COemissions up to 80% compared to fossil fuel. Like sustainable products in the supermarket, cleaner fuels are more expensive.

Flightnook also offers tree offsets so you can choose how you want to divide your contribution between cleaner fuels and trees.

Tackling passengers’ major concerns



Flightnook supports cleaner jet fuels made from materials that feed back into the circular economy, are sourced locally, and cut COemissions up to 80% on a lifecycle assessment.



Cleaner jet fuels are certified under conventional jet fuel regulations and can power today’s airplanes-- you won’t feel a difference, but the planet will.



We want to let you know what’s possible. Our calculator is based on the latest science and jet fuel regulations, plus we send you all the details of your impact.
