Anyone who communicates achievements in the area of sustainability is walking a fine line. We support you in formulating credible statements without greenwashing.

This applies:

According to the Federal Act on Unfair Competition, companies must ensure that their statements on climate impact are:

objective: statements must not be exaggerated or fabricated,

verifiable: claims must be substantiated with data, certificates, or other evidence.

Information should be presented in a clear, understandable, and comprehensible manner so that customers or partners can correctly assess the statements.

With its green marketing guidelines, the Fairness Commission supports Swiss companies with concrete examples.

Problematic Wording:

• Vague terms without evidence – such as “environmentally friendly,” “green,” or ‘sustainable’

• Green logos or icons that suggest sustainability without evidence to support this claim
• Self-invented seals or labels without external standards
