Appellate court upholds dismissal in high-stakes climate advertising case
New York’s long-running legal fight with major oil companies over advertising and climate claims suffered a setback after a state appellate court affirmed the dismissal of the city’s lawsuit against ExxonMobil, Shell and BP. The court concluded the firms’ marketing statements were comparative in nature and did not amount to the kind of deceptive conduct that municipal consumer-protection laws are designed to police.
The suit, originally filed in April 2021, alleged that the companies engaged in “greenwashing” by misrepresenting their commitments to clean energy and the climate impacts of their products. A trial judge dismissed the case in January 2025, finding there was insufficient evidence that climate-conscious New Yorkers had been deceived. The appellate ruling on Oct. 8, 2026 affirmed that decision.
“The relative reduced-emissions claims were not misleading”
Court’s reasoning and legal limits cited
According to the appellate court, the advertisements at issue made relative reduced-emissions claims rather than absolute guarantees about future emissions or the environmental footprint of the companies’ products. The judges found that those comparative statements would not reasonably deceive climate-focused consumers in a way that consumer-protection statutes remedy.
The court also determined the marketing campaigns were not sufficiently tied to the sale of specific goods or services to fall within the scope of municipal consumer-protection laws. In short, because the challenged communications did not directly relate to particular transactions, they lay outside the ordinance’s reach.
What this means for the city and future litigation
City officials, who pursued the case as part of a broader effort to hold fossil fuel companies accountable for their role in climate change, now face a narrower legal pathway. The appellate decision leaves open questions about which legal theories remain viable when municipal authorities challenge corporate environmental messaging.
- Legal precedent: The ruling reinforces limits on using municipal consumer-protection laws to police comparative corporate statements about emissions.
- City strategy: Officials will need to evaluate alternative legal avenues or focus on different statutes that more directly address alleged misrepresentations tied to commercial transactions.
- Corporate advertising: The decision may influence how companies craft environmental and emissions-related messaging to avoid regulatory scrutiny.
Timeline of the case
| Event | Date |
|---|---|
| Lawsuit filed by New York City | April 2021 |
| Trial court dismisses case | January 2025 |
| Appellate court affirms dismissal | October 8, 2026 |
Those following the matter noted the appellate court emphasized both the comparative nature of the statements and the lack of a direct link to a transaction, framing the ruling as a narrow statutory interpretation rather than a broad endorsement of all corporate climate claims.
Local implications and next steps
For New Yorkers, the ruling narrows one avenue for municipal redress against corporate communications about climate strategy and emissions. City officials have indicated they are considering their next legal steps, which could include identifying different statutory bases for claims or pursuing other forms of regulatory or policy action. The outcome also has implications for other municipalities contemplating similar suits.
At the same time, the decision does not settle larger debates about corporate responsibility for climate change or the substance of the emissions reductions companies claim. It addresses a specific legal question: whether the city’s municipal consumer-protection mechanisms apply to the kinds of marketing statements at issue. The appellate court said they did not.
As the city determines how to respond, stakeholders in government, environmental advocacy and industry will be watching how legal strategies adapt in the wake of the ruling. For now, the dismissal stands and marks a significant moment in the evolving landscape of climate-related litigation in New York and beyond.
