Biggest Greenwashing Scandals 2024-2026: The Cases That Changed Everything

The period from 2024 to 2026 will be remembered as the turning point when greenwashing went from reputational risk to legal liability. Courts ruled against major corporations. Advertising authorities banned campaigns across Europe. Consumer organisations filed coordinated complaints. And the EU adopted legislation that made many common environmental marketing practices explicitly illegal.

Here are the cases that defined this shift — and what each one means for businesses making environmental claims today.

KLM "Fly Responsibly" — Dutch Court Rules Against Airline (2024)

In March 2024, a Dutch court ruled that KLM's "Fly Responsibly" advertising campaign was misleading. The case, brought by environmental group Fossielvrij NL, challenged KLM's claims that consumers could fly sustainably by purchasing carbon offsets and that KLM was making flying more sustainable through sustainable aviation fuel (SAF).

The court found that KLM's ads created an "overly rosy picture" of the environmental impact of flying. Specifically:

SAF claims overstated the actual percentage in KLM's fuel mix (less than 1% at the time)
Offset-based carbon neutrality claims for individual flights were misleading given the overall growth in KLM's emissions
"Fly Responsibly" as a campaign slogan implied aviation could be environmentally responsible, which the court found unsupported by evidence

Why it matters: This was the first time a European court ruled that an entire corporate green marketing campaign — not just individual claims — constituted greenwashing. It established that industry-level environmental impact cannot be hidden behind product-level improvement claims.

TotalEnergies Advertising — French Court Ruling (2024)

Following a campaign by Greenpeace France and other NGOs, a French court found that certain TotalEnergies advertisements were misleading about the company's energy transition progress. The ads highlighted renewable energy investments while downplaying that over 90% of the company's business remained fossil fuels.

The court didn't challenge TotalEnergies' actual renewable energy investments — those were real. The issue was proportion: advertising renewable projects that represented a small fraction of operations while creating an impression of fundamental business transformation.

Why it matters: Cherry-picking positive data while omitting the broader picture is now legally actionable. Companies cannot highlight their greenest 5% while ignoring the other 95%.

Zalando Sustainability Filter — EU Investigation (2024)

The European Commission launched an investigation into Zalando's website sustainability filter, which allowed consumers to filter products by environmental criteria. The investigation found that the criteria for labelling items as "sustainable" were inconsistent, opaque, and in some cases, applied to items with no demonstrable environmental benefit.

Zalando modified its approach, replacing the vague "sustainability" filter with more specific attribute filters (recycled materials, organic content, etc.). The case influenced the ECGT's provisions on sustainability labels and environmental claims in e-commerce.

Why it matters: Website features that help consumers filter by environmental attributes are themselves environmental claims. The classification methodology must be transparent and substantiated.

Shein "evoluSHEIN" — Multiple Authority Actions (2024-2025)

Fast-fashion giant Shein's "evoluSHEIN" collection, marketed as using sustainable materials, attracted regulatory attention across multiple jurisdictions. The UK's ASA investigated claims about recycled polyester content. French consumer groups filed complaints about the use of "responsible" and "sustainable" in marketing for a company producing millions of garments per week.

The case highlighted a structural credibility gap: can an ultra-fast-fashion business model — built on overproduction, disposability, and cheap synthetic materials — credibly claim any product line is sustainable?

Why it matters: Business model credibility matters. Environmental claims that fundamentally conflict with the company's operating model face heightened scrutiny.

Deutsche Bank DWS "ESG Funds" — BaFin Investigation (2024-2025)

Germany's financial regulator BaFin investigated DWS (Deutsche Bank's asset management arm) over allegations that ESG fund marketing overstated the sustainability credentials of its investment products. The investigation followed whistleblower allegations that DWS was claiming more rigorous ESG integration than it actually practised.

DWS paid a $19 million SEC settlement in the US and faced ongoing regulatory scrutiny in Germany. The case became the defining example of financial services greenwashing — and directly influenced the SFDR's evolving disclosure requirements.

Why it matters: Financial product greenwashing faces dual enforcement under both financial regulations (SFDR) and consumer protection law (ECGT). Asset managers marketing to retail investors are particularly exposed.

Lidl "Climate Neutral" Products — German Consumer Groups (2025)

German consumer protection organisation vzbv challenged Lidl's use of "climate neutral" labels on various food products. The labels, certified by ClimatePartner, indicated carbon neutrality achieved through offset purchases. The vzbv argued this was misleading under both German competition law and the incoming ECGT.

Lidl was among several retailers and brands that removed "climate neutral" labels from products in anticipation of ECGT enforcement. ClimatePartner itself moved away from "climate neutral" terminology, rebranding to "ClimatePartner certified."

Why it matters: The carbon neutrality label market — once a growth industry — collapsed under regulatory pressure. Even certified carbon neutrality is now commercially risky in the EU.

Amazon "Climate Pledge Friendly" — EU Scrutiny (2025)

Amazon's "Climate Pledge Friendly" badge, displayed on products meeting certain environmental criteria, attracted EU scrutiny over the transparency and rigour of its qualification methodology. Consumer groups questioned which certifications qualified, how Amazon verified compliance, and whether the badge created misleading environmental impressions.

The case intersects with the ECGT's provisions on sustainability labels and the Green Claims Directive's expected requirements for e-commerce environmental claims.

Why it matters: Marketplace sustainability badges are environmental claims made by the marketplace, not just the seller. Platforms bear their own compliance obligations.

Primark "Primark Cares" — BEUC Coordinated Complaint (2025)

BEUC (The European Consumer Organisation) coordinated a complaint against Primark's "Primark Cares" labelling across multiple member states. The argument: a fast-fashion retailer selling garments at price points that preclude sustainable production cannot credibly attach a "Cares" label to a sub-collection without misleading consumers about the company's overall environmental impact.

Why it matters: Sub-brand environmental claims are evaluated in the context of the parent brand's overall operations. You can't carve out a "sustainable" product line to green the entire brand.

European Commission CPC Sweep — 344 Websites (2023-2024)

Not a single scandal but a systemic enforcement action. The European Consumer Protection Cooperation network screened 344 websites across the EU in a coordinated "sweep." Findings:

42% of screened websites contained environmental claims that could not be verified
57% of sustainability claims lacked adequate evidence
37% of claims used vague or general statements like "eco-friendly" or "sustainable"
Sectors with highest violation rates: fashion, cosmetics, and household goods

The sweep demonstrated that automated screening at scale is feasible and that non-compliance is widespread — providing political justification for the ECGT and Green Claims Directive.

Patterns and Lessons

Across all these cases, consistent patterns emerge:

Vague claims are the number one vulnerability. Every case involved some form of imprecise environmental language. Specificity is the best defence.
Offsets are toxic for marketing. Carbon neutrality through offsets attracted enforcement in every sector — aviation, retail, food, finance.
NGOs and consumer groups drive enforcement. Most cases were initiated by environmental organisations or consumer groups, not regulators acting independently. NGOs are strategic litigants targeting companies that maximise precedent value.
Sector matters. Fashion, aviation, energy, and financial services face the most scrutiny. If you're in these sectors, your compliance bar is higher.
Platform responsibility is growing. Marketplaces and platforms bearing sustainability badges or filters share liability for the environmental claims those features represent.
