The Anti-Greenwash Charter is an independent, not-for-profit signatory programme that champions organisations communicating responsibly. As a certified signatory, you publish your Green Claims Policy, have it independently reviewed, and earn your Charter mark, the visible proof of your commitment. We are not a regulator or a consultancy. Our focus is clear and specific: how you communicate responsibly, and how you demonstrate it.

“As a B Corp, we already hold ourselves to rigorous standards. Signing the Charter complements that commitment by bringing the same scrutiny to our communications, so how we communicate is as trusted and well-evidenced as what we do.”
“Becoming a certified signatory gave us confidence. The independent validation has strengthened our reputation and reassured both customers and colleagues that our communications are credible and responsible.”
“Joining The Anti-Greenwash Charter has demonstrated to our stakeholders that we take integrity seriously. It’s helped us build trust, protect our reputation, and be recognised as a leader in responsible communication within our industry.”
How It Works
Becoming a certified signatory is clear and well-supported, designed to validate your approach to communication.
1. Application and Assessment
We start with a comprehensive review of your media presence and regulatory history to confirm your suitability as a signatory.
2. Development and Approval
You’ll work with us to develop your own Green Claims Policy, with content reviews and training available based on your needs.
3. Recognition and Verification
Once approved, you’ll earn certified signatory status and your uniquely numbered Charter mark, the visible proof of your commitment.
The Standards
As a certified signatory, your organisation upholds four core standards of responsible communication:

1. Transparency
Clearly communicate the benefits of your product or service, ensuring no important information is concealed or omitted.

2. Accountability
Substantiate your claims with accurate, empirical evidence that is regularly evaluated. Share verifiable facts, figures, and statements.

3. Fairness
Use fair, clear, and unambiguous language when making comparisons with other products or organisations.

4. Honesty
Make specific, truthful statements about your progress, and ensure your actions align with your promises.
