Fly Carbon Neutral

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 CO2 emissions 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.
