BRUSSELS / GENEVA – The European Union Aviation Safety Agency (EASA) and the International Air Transport Association (IATA) have signed a Memorandum of Understanding designed to streamline how air travel emissions data is calculated, managed and displayed to passengers. The agreement explores operational synergies between the European Union Flight Emissions Label and IATA’s established environmental data platforms, EcoHub and CO2 Connect.
The collaboration aims to ensure that passengers receive accurate and consistent CO2 emissions information at the time of booking, while reducing administrative complexity for airlines. The EU Flight Emissions Label, established under a 2024 regulation and implemented by EASA, provides a unified framework for calculating and displaying emissions data. IATA’s EcoHub supports global airline sustainability reporting, while CO2 Connect uses primary operational data to calculate flight-specific emissions.
EASA and IATA will now examine how to align their processes to simplify label issuance and create a cost-efficient pathway for airlines.
Florian Guillermet, Executive Director of EASA, underlined the importance of industry-wide participation: “This partnership with IATA, the world’s largest airlines’ association, will make it easier for airlines to join the Flight Emissions Label. The more airlines we have on board, the better the overall information for air passengers, allowing them to make informed choices when they book their flights.”
Willie Walsh, Director General of IATA, emphasised the need for reliable data and reduced administrative burdens: “Regulatory compliance and customer demands for transparent emissions information must be met with the highest standards. Providing accurate emissions data is crucial for informed decision-making and for maintaining confidence in the sustainability of air transport. IATA’s EcoHub and our access to extensive sustainability data will give airlines an easier way to be part of the Flight Emissions Label. Our collaboration with EASA will focus on enabling an efficient and harmonized exchange of data, reducing administrative burdens, and achieving long-term cost savings for all stakeholders.”
The MoU was signed during IATA’s Wings of Change Europe conference, held on 18–19 November 2025 in Brussels.
Background: A unified approach to emissions transparency
The EU Flight Emissions Label (FEL) regulation, adopted in December 2024, enables passengers to compare flight emissions using a harmonised methodology. Airlines—both EU and non-EU—may voluntarily join the system, but only participating carriers are permitted to display emissions data in the EU when offering services such as SAF contributions or offset options.
The label’s digital-first structure aims to reduce administrative complexity while improving accountability and trust across the aviation sector.
IATA’s EcoHub and CO2 Connect play a key role in global emissions data management. CO2 Connect currently uses primary airline data from more than 90 airlines, with participation continuing to grow. Kenya Airways is the latest carrier to join the platform.
