Fly by impact

Lite Flights is not a normal flight search engine. We rank flights based on carbon emission not price or convenience. The lower the better.

We've built a detailed emission model for each aircraft type and route: modern, more efficient aircrafts are ranked higher. We match your planned trip with the available options and show you the routes with the smallest environmental impact.

Not all fights are created equal

Air travel is a significant contributor to the atmosphere's dangerous CO2 levels and emissions could triple by 2050. As the climate crisis deepens, the conflict between our need to fly and our responsibility to the planet escalates. We recognise that people will still fly, so we show you the options that will make a difference.

Every saving helps

Our CO2 impact model is based on extensive research and our database covers the vast majority of the world's airlines. We've built emission models for all aircraft types, from the latest Airbus A350-1000 to much older models such as the Boeing 747-400. Our route data is updated daily, and we regularly improve our modelling of aircraft and their respective CO2 emissions, so you can be confident of the impact of the routes you choose.
