Fashion giants Nike Superdry and Lacoste banned from Google ads for greenwashing

The Advertising Standards Authority (ASA) has taken decisive action against three prominent fashion and sports brands – Nike, Superdry, and Lacoste – by banning their paid-for Google ads. The ruling came after the ASA determined that these brands had misled shoppers by employing the term ‘sustainable’ without sufficient evidence to support such claims.

The core of the issue, as highlighted by The Guardian newspaper, was that the UK advertisements made sweeping claims regarding the sustainability of their products. Terms such as “sustainable,” “sustainable materials,” or “sustainable style” were used in the promotions, but the brands failed to provide the necessary proof to substantiate these “green claims.”

Each brand offered its own defense. Nike asserted that its promotion was “framed in general terms,” arguing that consumers would naturally interpret it as referencing only some, rather than all, of its product offerings. Superdry, whose ad urged consumers to “unlock a wardrobe that combines style and sustainability,” explained that the advertisement's purpose was to underscore its wide array of products that possess “sustainability attributes and credentials.”

Lacoste, which specifically promoted sustainable kids' clothing, acknowledged its dedicated multi-year efforts to reduce the carbon footprint across its entire product range. However, the brand candidly admitted that broad claims like “green,” “sustainable,” and “eco-friendly” are inherently “very difficult to substantiate.” The ASA, for its part, reiterated that the UK code of advertising explicitly requires environmental claims to be clear and “supported by a high level of substantiation,” a standard that the three companies’ ads failed to meet.

Consequently, the ASA banned each of the disputed advertisements. Furthermore, the regulatory body issued a clear mandate to the retailers, instructing them to “ensure that the basis of future environmental claims, and their meaning, was made clear, and that a high level of substantiation must be held to support absolute claims.” This ruling underscores a growing demand for transparency and verifiable evidence behind corporate environmental messaging.
