The International Air Transport Association (IATA) has launched an online tool that can provide accurate CO2 emission calculation from any commercial flight. 

Called the IATA CO2 Connect, the tool is a response to a growing demand for CO2 data transparency linked to airlines, and actual fuel burn information and load factors. IATA said that this is what sets the calculation tool apart from theoretical data models that exist in today’s market.

The program uses the newly developed CO2 Calculation Methodology which was adopted by IATA’s Passenger Service Conference in March 2022.

IATA CO2 Connect is available to companies and institutions such as travel management companies (TMCs), travel agencies, airlines, and multinational corporations. These companies can access the relevant CO2 emissions data and integrate it into their existing flight booking tools. 

IATA said that travel managers or travelers can easily see the CO2 emissions per routing. The tool also permits the consolidation of data for reporting purposes. 

American Express Global Business Travel (Amex GBT) is IATA’s launch partner for CO2 Connect. Managing more than $40 billion in travel sales annually, AMEX GBT hopes to provide its customers with the most accurate and reliable flight emissions data.

“Flying sustainably and cutting CO2 emissions is a top priority. The aviation sector is working to achieve net zero emissions by 2050 and travelers want to be more aware of their carbon footprint,” IATA’s Senior Vice President for Commercial Products & Services Frederic Leger said in a statement.

“With IATA CO2 Connect, individuals and corporate travel managers can get standardized accurate calculations to make the most sustainable choices for their air travel taking into consideration aircraft types, routings and class of service. Importantly, data can be consolidated for corporate reporting purposes,” Leger added.
