How does the IATA CO2 Connect calculator work?

IATA CO2 Connect provides users with CO2 emissions calculations based on a best practice industry methodology approved by the IATA Passenger Standards Conference (PSC). The calculator incorporates audited airline-specific fuel consumption data. It also considers airline-specific cargo weight, load factors, and cabin configurations.

The calculator uses actual fuel consumption data, covering 74 aircraft types which represents ~98% of the active global passenger fleet, and traffic data from 881 aircraft operators representing ~93% of global air travel.

How are CO2 emissions calculated

  1. Calculation of total CO2 emissions for a given flight
  2. Distribution of CO2 between passenger and cargo payload based on weight
  3. Allocation of CO2 between passengers considering expected occupancy and cabin classes
