From 27 September 2026, EU rules on green claims allow sustainability labels to be shown to EU consumers only when they are based on a certification scheme with independent third-party monitoring, or established by public authorities.
Travalyst, the not-for-profit coalition working on shared sustainability standards for the travel industry, keeps the list of certification schemes that have declared they meet those requirements, and shares it with its booking-platform partners. Tuu Verified is now on that list.
How Tuu Verified works
- Open to any hotel on published criteria and published fees.
- Independent third-party monitoring. Every quarter, HLB, a global network of independent accounting and advisory firms, checks each property's reported energy, water, waste, food and training data against its supporting evidence.
- A time-limited label. Tuu issues the Smart Trust Mark to a named property for a stated period, recorded on the BlockMark Registry, and suspends or withdraws it if a property no longer meets the requirements. The full procedure is set out in our methodology.
What it means for hotels
Booking platforms increasingly show sustainability information to travellers, and under the new EU rules labels must be backed by a certification scheme or a public authority. For a Tuu Verified hotel, that means its label comes from a scheme on the list the platforms work from.
Travalyst does not assess or approve schemes; each scheme declares its own compliance and remains responsible for it. You can read more about the initiative on Travalyst's website.
