Misleading Advertising

Ensuring Legally Compliant Sustainability Claims

Misleading advertising refers to marketing statements that deceive consumers or create false expectations. Particularly problematic are sustainability claims that are unverified or deliberately vague.

According to the Unfair Competition Act (UWG), misleading advertising is prohibited if it deceives consumers or competitors and influences purchasing decisions. Violations can lead to legal warnings, fines, and lawsuits under competition law.

Why Is Misleading Advertising Problematic?

Unclear or false advertising claims not only damage consumer trust but also distort fair competition. Key consequences include:

  • Consumer deception – Customers purchase products that do not meet their expectations.
  • Distorted competition – Companies that communicate sustainability honestly are at a disadvantage compared to those that mislead consumers.
  • Legal risks – Violations of the UWG can result in warnings, fines, and legal action.
  • Reputational damage – Companies exposed for greenwashing risk long-term harm to their brand image.

Examples of Misleading Advertising

Misleading Sustainability Advertising

Many companies promote sustainability without providing concrete evidence. Examples include:

  • “Climate neutral” – without specifying how emissions are reduced or offset.
  • “Sustainable packaging” – even if only a minimal percentage of recycled material is used.
  • “Biodegradable” – without proof of the conditions required for proper decomposition.

Misleading Food Advertising

False or misleading claims are also common in the food industry:

  • “100% natural” – despite containing artificial additives.
  • “Sugar-free” – while including sugar substitutes that still contain calories.
  • “Ethically sourced” – without clear, defined industry standards.
