Air France-KLM Joins EU Label as Flight Emissions Move Into Booking

Air France-KLM became the first airline group to work with the European Union Aviation Safety Agency on the EU Flight Emissions Label in July 2025.

The label is designed to show passengers clearer information about the carbon emissions linked to their flights before they book.

Air France and KLM will help EASA test the system before wider use. Their role includes checking how airlines submit data, how EASA validates it, and how the final emissions information could appear during the booking process. This gives regulators practical feedback from one of Europe’s largest airline groups.

What the EU wants to change

Flight emissions data is often hard to compare. One airline, travel agency, or carbon calculator may show different results for the same journey because they use different methods. The EU wants to fix this with one common system.

The Flight Emissions Label will use a shared method for calculating and displaying emissions. It can include details such as aircraft type, passenger numbers, freight, fuel use, and sustainable aviation fuel.

Why travel companies should care

The label could make emissions data a normal part of flight shopping. Travelers already compare price, schedule, baggage rules, and loyalty benefits. In Europe, they may soon see verified emissions information next to those details.

How it fits Air France-KLM’s climate plans

Air France-KLM says the project supports its wider decarbonization strategy. The group is investing in newer aircraft, sustainable aviation fuel, more efficient flight operations, and air-rail options where trains can replace or support short-haul flights.

The label itself will not reduce emissions. Its value is transparency. It gives passengers and corporate buyers a clearer way to understand the estimated footprint of a flight, while airlines continue the harder work of cutting fuel use and increasing cleaner fuel supply.

Aviation emissions data is becoming more important for regulators, airlines, corporate travel managers, and booking platforms. Technology providers are moving in the same direction. Recently, Amadeus, SITA, and AACO partnered to improve flight carbon footprint data, demonstrating that emissions transparency is becoming a broader industry requirement, not just a single regulatory initiative.
