What’s Required

Denmark prohibits misleading environmental and climate-related marketing under the Marketing Practices Act.

Key requirements include:

  • Environmental claims must be accurate, clear, and capable of substantiation.

  • Claims such as “climate-neutral”, “CO₂-neutral”, “environmentally friendly” or “certified” must be supported by robust evidence.

  • Documentation must exist before marketing is published, not generated retrospectively.

  • Overall impression, not isolated wording, determines compliance.

Important Deadlines

  • Obligations apply continuously and immediately whenever marketing materials are released.

Current Status

Enforcement activity has intensified, with increased scrutiny of climate claims by the Consumer Ombudsman and the courts.

Penalties for Non-Compliance

  • Administrative fines for misleading environmental claims.

  • Orders to withdraw or correct marketing materials.

  • Reputational damage amplified by public enforcement announcements.

Examples of Known Violations

  • Marketing products as environmentally certified without sufficient substantiation.

  • Using absolute climate claims without clear scope, boundaries, or offset explanations.
