This section identifies severe legal and regulatory risks in advertising. Under frameworks like the US Green Guides and the UK Green Claims Code, brands making unsubstantiated or false ecological statements face strict legal enforcement, consumer fraud lawsuits, and massive financial penalties for deceptive marketing.

Serious ethical violations occur when a structural gap exists between a fashion brand's green rhetoric and its actual operational practices (decoupling). Resorting to greenwashing tools while advertising high CSR standards highlights corporate dishonesty, misleads public perception, and erodes consumer green trust.

The use of broad, buzzword-heavy environmental terms like "eco-" or "sustainable" without standardized definitions or transparent supply chain data is a clear manifestation of linguistic vagueness. This advertising strategy deliberately exploits positive consumer associations to fabricate a green image while omitting actual product footprints.

Marketing recycled plastic bottles (PET) as a definitive step toward "sustainable fashion" is highly misleading. This practice functions as a sustainability decoy that obscures the larger environmental harm of fast fashion, completely ignoring the industry's failure to implement genuine, circular fiber-to-fiber recycling.
