The checklist

Ten essential actions against greenwashing

From verifying data to backing claims with evidence that reflects actual performance, the checklist is a practical guide to strengthening transparency and credibility.

It covers ten focus areas to help you assess current practices and spot gaps that could expose your organisation to greenwashing risk:

  • Clear reporting boundaries
  • Verified sustainability claims
  • Absolute and relative metrics
  • Alignment with reporting standards
  • Balanced performance
  • Claims matched with resources
  • Validated certifications and awards
  • Future goals linked to present action
  • Stakeholder engagement
  • Documentation and audit trails

Who it is for: chief sustainability officers, sustainability and communications teams, and legal and compliance functions reviewing environmental claims before they are published.

Why it matters

Three reasons to take greenwashing risks seriously

Scrutiny is intensifying

Regulators, NGOs and consumers are quick to call out misleading claims, and the consequences are real. Investigations, fines and reputational damage can all follow when claims don’t hold up.

Greenwashing can undermine real progress

Even well-intentioned sustainability work can lose credibility if disclosures are inconsistent, incomplete or unclear. A single vague or overstated claim can damage trust across the board.

Prevention is easier than crisis control

A few key actions, like verifying data, documenting decisions and setting clear boundaries, can significantly reduce risk. The checklist helps you spot gaps before others do.
