The UK Advertising Standards Authority (ASA) has banned advertisements from Calvin Klein, Adidas, and Uniqlo for making unsubstantiated claims about recycled clothing. The watchdog ruled that the companies failed to provide sufficient evidence to support their environmental assertions, forcing them to cover the ads with banners at featured locations.
Details of the Banned Ads
Adidas promoted “recycled running shoes,” Calvin Klein advertised “recycled” tops for women, and Uniqlo marketed fleece coats and jackets made from “recycled materials.” The ASA intervened after determining that these claims could mislead consumers.
Company Responses
Adidas stated it did not have a specific recycled running shoe range but that certain products might use recycled materials, with internal documentation to back its claims. Calvin Klein said some products in its women’s T-shirts and tops line included “environmentally preferred materials,” such as recycled, organic, and other materials, arguing that consumers would not interpret the ad as applying to the entire range. Uniqlo asserted that customers would understand the products were made to a “meaningful extent” from recycled materials, supported by an international certification scheme.
ASA Statement
Miles Lockwood, ASA director of complaints and investigations, said: “It’s important that people can trust the environmental claims they see in ads. When absolute terms like ‘recycled’ are used, the basis of those claims should be clearly explained and properly supported by evidence. Without that, there’s a risk that people could be misled. We’ll be continuing to monitor ads making green claims, taking action where we do see ads breaking the rules, whilst also supporting advertisers with advice and guidance to help them get it right.”
Impact and Future Monitoring
The ASA's ruling underscores a growing scrutiny of greenwashing in advertising. The watchdog plans to continue monitoring environmental claims and will enforce compliance, while also offering guidance to help advertisers avoid misleading statements. The decision affects prominent global brands and serves as a warning to the fashion industry about the need for transparency in sustainability marketing.
