European airlines, including Lufthansa, Air France, and KLM, have agreed to stop making misleading environmental claims about offsetting the carbon emissions from air travel, the European Commission announced on Friday.
The pledge from 21 carriers will oblige them to clarify that the emissions of a specific flight cannot be “neutralised, offset, or directly reduced” by contributing to climate protection projects or alternative fuels—claims Eurocrats say amount to greenwashing.
“To avoid misleading consumers, airlines must refrain from using vague environmental language and ensure that any claims about future environmental performance are substantiated,” the commission said in a statement.
Airlines also pledged to present carbon emission calculations clearly and transparently and provide robust scientific evidence when claiming environmental improvements.
The carriers concerned are Air Baltic, Air Dolomiti, Air France, Austrian Airlines, Brussels Airlines, Eurowings, EasyJet, Finnair, KLM, Lufthansa, Luxair, Norwegian, Ryanair, SAS, SWISS, TAP, Transavia France, Transavia CV, Volotea, Vueling and Wizz Air.
The commitments follow a formal complaint lodged with the European Commission in June 2023 by consumer groups, which accused the aviation sector of misleading advertising practices.
The industry has begun to shift its messaging after a series of legal setbacks.
In March 2024, a Dutch court ruled against KLM in a greenwashing case, saying the airline misled consumers with vague claims about the sustainability of its flights.
A year later, a German court barred Lufthansa from advertising carbon offsetting in a way deemed deceptive.
Air France no longer offers carbon offsets for flights. Instead, it suggests passengers contribute to the purchase of sustainable aviation fuel (SAF).
