Air Serbia, Malaysia Airlines, Qatar Airways and Vietnam Airlines joined IATA’s CO2 Connect calculator program at this week’s IATA AGM Summit in Dubai. The development will enable passengers to check their carbon footprint when they fly with the airline. The Serbian carrier will share operational data with IATA’s CO2 Connect emissions calculator. CO2 Connect, launched by IATA in June 2022, uses airline data to calculate passenger CO2 emissions. It covers 74 aircraft types, representing nearly 98% of the global passenger fleet, and incorporates data from 881 operators, covering about 93% of global air travel. The tool’s data is accessible through various channels like APIs, flat files, airline sales channels, and travel management companies. IATA CO2 Connect will continue evolving, with recent additions including a corporate reporting solution for business travel emissions. Furthermore, this year, CO2 compensation solutions are being introduced. Additionally, a cargo calculator has been developed, catering to shippers and freight forwarders seeking accurate CO2 emissions data from actual airline records.
