Landmark greenwashing lawsuit against KLM airline granted court permission

A groundbreaking greenwashing lawsuit against airline KLM challenging its misleading advertising has been granted permission to proceed to a full hearing by a Dutch court.

The lawsuit – the first of its kind to challenge airline industry greenwashing – argues that KLM's climate ads and offset marketing breach EU consumer law standards by creating a false impression that its flights do not contribute to the worsening climate emergency.

The District Court of Amsterdam has granted permission for Dutch campaigners Fossielvrij and Reclame Fossielvrij to bring the claim, following a hearing in April on the organisations’ admissibility. The decision establishes for the first time that an environmental non-profit can bring a greenwashing claim under the recently passed Dutch class action law.

It comes after KLM informed the judge that it had dropped its ‘Fly Responsibly’ advertisements, which were challenged by the lawsuit.

Hiske Arts, campaigner at Fossielvrij, said: “Today’s ruling rightly confirms that climate organisations have a place in combating greenwashing. With the threat of this lawsuit, KLM stopped its problematic ‘Fly Responsibly’ campaign.

“But KLM continues to greenwash its growth ambition through other climate messages. It is important that the Court assesses the full spectrum of KLM’s statements, because as long as the biggest polluters continue to lull us to sleep through their slick marketing campaigns, climate action will not happen.”

KLM’s misleading statements

Although KLM has discontinued its ‘Fly Responsibly’ ad campaign, it has not made any commitments regarding its future advertising, nor has it addressed the carbon offset marketing that is also targeted by the lawsuit.

Fossielvrij’s claim argues that this marketing misleads customers into thinking they can reduce their flight's impact by supporting reforestation projects or the airline’s costs of purchasing small quantities of biofuels.

The lawsuit also challenges KLM’s claim that the company is “creating a more sustainable future” because of its net zero by 2050 target, which is at odds with its plans for continued business growth.

According to the Court, it is not in dispute that the misleading allegation has sufficient merit to proceed to the next phase of the litigation.

Johnny White, a lawyer from ClientEarth, added: “The truth is that KLM’s climate publicity push extends far beyond a single campaign. This is not an isolated incident in the airline industry. The ongoing struggle to stamp out aviation greenwashing underscores the urgent need to ban fossil fuel advertising and protect the public from misleading practices that subvert climate action.”

The Court said Fossielvrij can now consult KLM and amend its claim to focus on the advertising the airline stands by. KLM then has six weeks to file a full defence.
