Consumers are increasingly demanding eco-friendly products, expecting brands to showcase authentic environmental impact in marketing efforts effectively.
Sustainable advertising claims must be truthful and supported by evidence. Without proper proof, companies risk greenwashing, misleading consumers, and losing credibility.
The Advertising Standards Authority (ASA) recently banned adverts from Nike, Superdry, and Lacoste for using terms such as “sustainable,” “sustainable materials,” or “sustainable style” without sufficient substantiation.
These rulings underscore the importance of clarity and accuracy in sustainable advertising claims, ensuring consumers can make informed decisions about environmentally responsible products.
Globally, regulatory guidance, such as the FTC Green Guides, provides standards for green marketing US companies to avoid misleading sustainability claims in advertising.
Companies referencing the FTC Green Guides PDF or summary documents can find practical sustainable advertising claims examples to ensure compliance and consumer trust.
Nike and Sustainable Advertising Claims
The Nike Ad Controversy
In June, Nike ran a Google ad promoting tennis polo shirts that claimed the use of “Sustainable Materials” in production.
Nike clarified that the ad referred to a range of products incorporating recycled polyester and other environmentally conscious materials rather than the entire product line.
The ASA concluded that the claim was absolute and required a high level of substantiation. The company had not demonstrated that the tennis polo shirts caused no environmental harm across their full life cycle.
Lessons from Nike
Nike’s case demonstrates that even partial environmental improvements require careful communication in advertisements.
Short-format digital ads, like Google paid promotions, cannot overstate sustainability claims without supporting evidence. Sustainable advertising claims examples help avoid misleading consumers and maintain trust.
Brands must also consider automated ad systems, which may display messages in ways that exaggerate eco-friendly claims, requiring careful planning and transparency.

Superdry and the Challenges of Sustainable Advertising Claims
The Superdry Ad
Superdry’s Google ad stated: “Sustainable style. Unlock a wardrobe that combines style and sustainability,” promoting its fashion collection.
The company explained that the ad highlighted products with sustainability attributes and did not claim that the entire product range was fully sustainable.
ASA Findings on Superdry
Although 64% of its 2024 garments, footwear, and accessories were made with sustainably-sourced materials, the ASA determined that the ad could mislead consumers into thinking all products had no environmental impact.
The ASA concluded that the use of “sustainable” in the ad was ambiguous and likely to be misunderstood, reinforcing the need for substantiated sustainable advertising claims.
Insights for Brands
Superdry’s experience emphasizes precision in advertising language. Companies must avoid vague statements that can exaggerate environmental benefits.
It is essential for brands to clearly differentiate between products with verified eco-friendly materials and other items, ensuring consumers receive accurate information.
Lacoste and Kids’ Clothing Sustainable Advertising Claims
Lacoste’s Ad and Environmental Efforts
Lacoste promoted its kids’ clothing as “sustainable,” highlighting its efforts to reduce the environmental impact of its materials and production processes.
The brand conducted life cycle analyses and reported a 19% reduction in the environmental footprint of raw materials between 2022 and 2025.
Regulatory Ruling
Despite these measurable improvements, the ASA concluded that the ad could mislead consumers into assuming that all products were environmentally harmless.
Lacoste promptly withdrew the ad and committed not to repeat the claim in the same form, emphasizing the importance of transparency in sustainable advertising claims.
Lessons from Lacoste
Even verified improvements must be communicated accurately in marketing materials. Brands can refer to frameworks such as the FTC Green Guides PDF or summaries to support claims.
Clear communication ensures compliance, protects consumer trust, and demonstrates corporate responsibility in green marketing US and UK contexts.
Regulatory Landscape: ASA and FTC Green Guides
ASA Guidance in the UK
The ASA enforces the CAP Code, which mandates that environmental claims be clear, substantiated, and transparent about the product’s full impact.
Claims must reflect the entire life cycle of the product and avoid suggesting all items are eco-friendly when only a portion meets sustainability criteria.
FTC Green Guides in the US
In the United States, the FTC Green Guides provide guidance for companies engaged in green marketing US, outlining how to communicate environmental claims responsibly.
The guides specify that unqualified terms like “eco-friendly” or “sustainable” must be substantiated. Brands are encouraged to reference sustainable advertising claims examples when drafting marketing messages.
Staying Updated
Companies must remain aware of regulatory changes and the question of when will FTC Green Guides be updated.
Resources such as FTC Green Guides PDF or summary documents provide guidance to ensure advertising remains compliant and trustworthy.
Greenwashing in the Fashion Industry
What is Greenwashing?
Greenwashing occurs when companies exaggerate environmental achievements to gain marketing advantages. Misleading claims may appear in product labels, ads, or online campaigns.
High-profile cases include Innocent (Coca-Cola), Wizz Air, Lloyds, Total Energies, and Brewdog, all sanctioned for unsubstantiated environmental claims.
Implications for Brands
Greenwashing can severely damage brand reputation and consumer trust. Regulatory penalties may include fines or mandatory withdrawal of misleading advertisements.
Fashion brands, in particular, must provide verifiable evidence of sustainability, such as life cycle assessments, certified fabrics, or carbon footprint reductions. Sustainable advertising claims examples can guide marketers in communicating environmental achievements responsibly.

Additional examples include measurable reductions in water usage, energy consumption, or carbon footprint, validated by life cycle assessments.
Verified certifications for organic or recycled fabrics provide credibility, while sustainable advertising claims examples in marketing materials ensure transparency and consumer confidence.
