Aviation emissions are growing annually, but efficiencies are improving.
The Dashboard uses a unique approach to estimating total global passenger carbon dioxide emissions. Data stem from the Amadeus booking database in combination with ICAO emission factors that are specific to each airport-airport pair. In 2016, ICAO updated their factors to take into consideration new aircraft types and more efficient technology. Amadeus data constitute a combination of actual bookings through the Amadeus platforms and modelled data to account for bookings made through other Global Distribution Systems.
