Are Nike, Lacoste & Superdry Adverts Greenwashing?

Three prominent fashion brands have been publicly rebuked by the UK’s Advertising Standards Authority (ASA) for making unsubstantiated environmental claims about their products. 

The ASA has banned paid-for Google advertisements from Nike, Lacoste and Superdry after ruling that the brands did not provide the required evidence to support the sustainability claims made in their promotions. 

These rulings are part of a wider regulatory focus on greenwashing within the fashion industry which, according to the UN, contributes to between 8% and 10% of global emissions.

Substantiating sustainability claims

The ASA’s interventions target specific advertising claims. A Google ad from Nike for its tennis polo shirts promotes the use of "sustainable materials". 

Nike argues the promotion is "framed in general terms" and suggests consumers would understand it applies only to specific products on its website that use recycled materials. 

The ASA rejects this position, ruling that Nike failed to include necessary qualifying details or clarify the basis of its sustainability assertions.

Superdry’s advertisement encourages shoppers to "unlock a wardrobe that combines style and sustainability". 

The company contends that customers would interpret this to mean its clothing was either stylish, sustainable or a combination of both, noting that its entire product line meets high environmental standards. 

The ASA however finds these claims are "ambiguous and unclear", potentially leading consumers to believe all Superdry products are sustainable.

Lacoste promotes its children's range as "sustainable clothing". 

While the brand told the ASA it has worked for years to lower the carbon footprint of its products, the ASA argues Lacoste cannot demonstrate that this specific range has “no detrimental effect on the environment”. 

In its communication with regulators, Lacoste acknowledges that terms like "sustainable" and "eco-friendly" are "very difficult to substantiate". In each case the ASA concludes the ads are likely to mislead.

AI enforcement and regulatory standards

The rulings are based on the UK advertising code, which mandates that environmental claims must be clear and "supported by a high level of substantiation". 

The ASA determined that the brands' use of the term "sustainable" was presented as an absolute claim without sufficient context or qualification. 

"The claim was absolute and therefore a high level of substantiation in support needed to be produced", the ASA stated. "We had not seen evidence to support it. We therefore conclude the ad is likely to mislead."

The advertisements in question are identified through the ASA's monitoring system, which utilises AI to scrutinise the legitimacy of claims in the fashion sector’s advertising. 

"These rulings send a clear message that advertisers must be able to back up their green claims with solid evidence so people get fair accurate information when they're choosing what to buy,” explains Justine Grimley Operations Manager at the ASA.

This use of technology signals a new phase in enforcing regulations against greenwashing. Conversely as advertisers themselves increase their use of AI a key concern may emerge. 

According to Brinsley Dresden, Co-Head of Advertising and Marketing Law at Lewis Silkin, AI-generated advertisements create a "big challenge" for advertisers making tightly regulated green claims.

The fashion sector's greenwashing challenge

The fashion industry is facing increasing scrutiny from both consumers and regulators. 

According to the Ellen Macarthur Foundation, the equivalent of one truckload of clothing is incinerated or sent to a landfill every second. 

While the market for second-hand clothing is growing the World Bank suggests global clothes sales could increase by 65% by 2030. This leads to greater demand for transparency regarding production methods and materials.

This is not the first instance of regulatory action in the sector. Last year the UK's Competition and Markets Authority (CMA) reprimanded fast-fashion retailers Asos and Boohoo along with Asda's George clothing line over similar unsubstantiated environmental claims. The CMA's guidance for the industry notes that broad claims such as "sustainable" are likely to mislead consumers.

Nike says it remains “committed to providing consumers with clear information to help them make the choices that are right for them.” 

Lacoste told the Financial Times it had reduced the environmental footprint of raw materials in its children's collection by 19% since 2022. 

Superdry did not respond to requests for comment.
