Travalyst has scaled flight emissions information globally, with emissions data appearing in over 65 billion searches1. The search figure, released by Travalyst – the not-for-profit organisation founded by Prince Harry, The Duke of Sussex – aggregates data from a number of its coalition partners2, which include Amadeus, Booking.com, Expedia Group, Google, Sabre, Skyscanner, Travelport, and Trip.com Group. Travalyst’s mission is to align the travel industry behind clear, consistent and credible sustainability information to help people make more informed choices. The Travel Impact Model (TIM), which estimates lifecycle emissions for flights at the individual passenger level, was developed by Google and has been scaled through the Travalyst coalition. Platforms using the TIM present flight emissions information at the time of booking, so travellers are able to choose a flight with an estimated lower-than-typical CO2e footprint3. On some platforms, travellers can also sort flight search results by emissions, alongside standard filter options such as cost and arrival/departure time. For example, the typical CO2e per passenger on a one-way economy flight from London (LGW) to New York (JFK) is 466 kg4. Popular travel booking platforms highlight an option that is 12% (57 kg) lower than the typical CO2e for that route. The difference in CO2e is approximately equivalent to a passenger’s flight from London (LGW) to Dublin (DUB) (typically 56 kg CO2e). The TIM takes a variety of attributes into account including flight origin and destination, aircraft type, cabin class and seat configuration, load factors and average aircraft utilisation. With such granular data comes the ability to see emissions at individual airline level, which could pave the way for airlines to compete on reducing their climate impact, as well as price and service. …
