The EU Just Made It Illegal to Lie About Your Product's Green Credentials — The Greenwashing Crackdown Begins

The EU's Green Claims Directive is entering enforcement. Here is what companies can no longer say about their environmental credentials and what the penalties are.

The EU's Green Claims Directive — the legislation that requires companies making environmental claims about their products to substantiate those claims through verified scientific evidence before making them publicly — has been moving through the implementation phase in a way that is beginning to produce enforcement action. The specific prohibitions are broader and more practically significant than general awareness of the legislation suggests.

Prohibited claims under the implemented directive include: the designation 'environmentally friendly,' 'eco,' 'green,' 'nature-friendly,' or similar without specific substantiated evidence of the environmental benefit claimed; claims of carbon neutrality based solely on carbon offset purchasing without genuine emissions reduction; use of sustainability labels not based on EU-approved or independent certification schemes; and forward-looking claims about future environmental performance that are not backed by specific, credible, publicly available plans with binding commitments.

The enforcement architecture is national — each EU member state's consumer protection or environmental authority is responsible for investigating and penalising violations. The penalties vary by member state but can reach 4 percent of annual turnover for large companies, creating a financial incentive that sustainability compliance advisors describe as finally comparable to the scale of the deceptive competitive advantage that greenwashing provided.

For the marketing and advertising industry, the practical consequence of the directive's enforcement is significant. A substantial proportion of environmental claims currently appearing in European consumer advertising — particularly the vague qualifier language ('responsible,' 'sustainable,' 'conscious') that has been a staple of brand communication — is either already non-compliant or requires substantiation investment to remain compliant.

For consumers, who surveys have consistently shown are confused about the reliability of environmental claims and have largely stopped trusting them, the directive's enforcement represents the first systematic attempt to create a verified environmental claim environment rather than leaving consumers to navigate an unverified claim landscape independently.
