Nike, Lacoste, and Superdry Ads Banned for Misleading Sustainability Claims

The UK Advertising Standards Authority (ASA) has banned ads from Nike, Lacoste, and Superdry due to “misleading” and unqualified environmental claims, intensifying its crackdown on greenwashing in marketing.

Nike’s “Sustainable Materials” Claim Overstated

• Ad Content: Nike’s search ad for tennis polo shirts used the headline “Serve An Ace With Nike…Sustainable Materials,” linked to products tagged as containing at least 75% recycled fibres.
• ASA Ruling: The ASA ruled the claim was general and absolute, misleading consumers to believe the entire product was sustainable.
• Substantiation: Nike’s evidence focused on cradle-to-gate CO₂ reductions for recycled polyester but lacked comprehensive lifecycle data (including manufacturing, distribution, use, and disposal).
• Outcome: The ad was banned as it overstated overall product sustainability.

Lacoste’s “Sustainable Clothing for Kids” Ad Deemed Unqualified

• Ad Content: Lacoste promoted a children’s collection claiming sustainability through GOTS-certified organic cotton, recycled fibres, and responsibly sourced wool.
• Evidence Provided: Lifecycle assessments showed 19% raw material and 17% manufacturing impact improvements compared to 2022.
• ASA Issue: The ad’s broad claim implied overall sustainability of the kidswear line, failing to clarify that only 78% of the range met material criteria.
• Conclusion: Lacoste’s claim was considered unqualified and misleading without full lifecycle substantiation, leading to an ad ban.

Superdry’s “Style and Sustainability” Promise Found Misleading

• Ad Content: Superdry’s paid search ad promoted a “wardrobe that combines style and sustainability,” linking to womenswear with mixed sustainability credentials.
• ASA View: The claim was a general environmental assertion requiring full evidence, which was not provided.
• Problem: The presence of products without environmental credentials alongside sustainable items risked misleading consumers about the entire range.
• Decision: The ad was banned for lacking clarity and supporting data on environmental impact.

ASA’s Core Message to Brands on Sustainability Advertising

• Claims must be clear, specific, and evidence-based.
• Marketing should avoid broad, unqualified, or aspirational sustainability statements.
• Brands must demonstrate full lifecycle environmental benefits before using generalized sustainability claims.
• Failure to comply risks ads being banned and reputational damage over “greenwashing.”

Implications for Sustainable Product Marketing

For companies in organic and sustainable product sectors, these rulings underscore the need to:

• Provide transparent, lifecycle-based evidence for all sustainability claims.
• Use precise, qualified language to avoid consumer confusion.
• Clearly distinguish which products or materials meet sustainability standards.
• Anticipate stricter regulatory scrutiny on environmental marketing.

By holding major brands accountable, the ASA is driving higher standards and consumer trust in sustainability advertising—a vital stance for the credibility of the organic and sustainable product market.
