Climate communication in the Airline Industry: moving past greenwashing to rebuild credibility

No industry is under closer environmental scrutiny than air transport when it speaks about the climate. And starting September 27, just days after the 2026 edition of the IFTM Top Résa trade show, the room for error will shrink even further. The EU's EmpCo directive comes into full force across every member state, and seven environmental communication practices become directly prohibited with no need to even prove an intent to mislead. For an industry that has long navigated between bold ambition and legal caution, this marks a genuine change of regime.

September 27, 2026: the room for error disappears

The framework now governing brands is no longer a loosely interpreted code of ethics. It has been accumulating, layer upon layer, with each new text adding to rather than replacing the last: the 2023 Climate Law, the French Consumer Code, the EmpCo directive (EU 2024/825), and the Green Claims regulation still making its way through the European process.

In practical terms, any environmental claim must now be backed by scientific evidence proportionate to the scale of the claim itself. Vague wording — "eco-friendly," "responsible," "environmentally friendly" used on their own — is no longer enough. It must be replaced with verifiable, quantified data, anchored in recognised standards: ISO 14021, multi-criteria life-cycle assessment, Bilan Carbone®.

The penalties are far from symbolic: up to 10% of turnover under France's DGCCRF, and up to €100 million under the AMF for claims with financial implications. Nor is the exposure theoretical — more than 1,200 checks are already carried out every year in France, with anomaly rates reaching 30 to 40% depending on the sector.

The JDP has already ruled and the lesson goes beyond classic greenwashing

One precedent deserves close attention, precisely because it doesn't involve an explicit green claim at all. An airline had run a campaign showing a young woman cycling through Venice, Athens, Seville, Budapest and Amsterdam, under the tagline: "Never spend your weekends in the same place twice."

Following a complaint from ADEME (the French environment and energy agency), France's Advertising Ethics Jury (JDP) ruled the complaint well-founded: the message could be read as encouraging people to fly every single weekend, in direct tension with the moderation principles set out in France's National Low-Carbon Strategy.

The jury didn't accuse the advertiser of lying about its emissions — it faulted the campaign for a lack of clarity on a subject that has become sensitive. That is the most important lesson for the airline industry in 2026: the risk is no longer confined to campaigns that claim to be green. It extends to any communication that, even without saying so, glorifies unlimited air travel. Scrutiny now has to cover the overall tone of a message, not just whether the word "green" appears in it.

Carbon offsetting: the end of an easy argument

For years, carbon offsetting served as a quick, reassuring answer to the climate question: pay to plant trees elsewhere, and present the flight as neutral. That argument is becoming one of the riskiest a brand can make. Claims of being "carbon neutral" without a real, documented reduction in emissions are now prohibited, as is presenting an offset as equivalent to neutrality. The message behind this new framework is unambiguous: offsetting is not the same as reducing, and any communication that blurs the two is directly exposed.

What's still possible: how to talk credibly about climate commitment

This regulatory tightening doesn't rule out climate communication in the airline sector — it rules out imprecision. Several principles make it possible to keep talking about the subject without taking on unnecessary risk:

• Quantify, always. Replace "we are reducing our impact" with a verifiable figure: the actual share of sustainable aviation fuel (SAF) blended in, or the reduction in emissions per passenger-kilometre against a clearly defined baseline year.

  
  

• Explicitly separate reduction from offsetting. Never imply that an offsetting mechanism cancels out or erases an emission; state clearly when a figure relates to one or the other.

  
  

• Ban standalone qualifiers such as "green," "neutral," or "responsible," replacing them systematically with the evidence that justifies them — or dropping them altogether.

  
  

• Document claims against a recognized framework (ISO 14021, multi-criteria LCA) rather than an internal methodology that cannot be verified by a third party.

  
  

• Look at the overall tone of a campaign, not just its climate message. Communication that celebrates travel frequency or volume can be challenged even without mentioning the environment at all, as the JDP ruling shows.

  
  

• Show a trajectory rather than a finished state. A documented trend, even a modest one, is now more credible — and more legally defensible — than a promise of immediate exemplarity.

And as IFTM approaches?

Climate communication in the airline industry is entering a phase where precision becomes a strategic skill in its own right, on par with creativity. Airlines heading into the 2026 edition of IFTM Top Résa and this autumn with a vague narrative about their environmental trajectory are no longer just taking a reputational risk — from late September onward, they are taking a direct regulatory one. Conversely, those able to precisely document what they are actually doing, without overstating what they can prove, will turn a legal constraint into a credibility advantage with increasingly well-informed clients.
