Zannier Hotels Bãi San Hô was independently verified by Tuu in May 2025 under the Bamboo Badge framework, Tuu's earlier verification model. The verification covered six consecutive months of operational data across five impact areas — Energy, Water, Food, Waste and Local Employment — reviewed by HLB International against benchmarks aligned with the GSTC Industry Criteria, UNEP and ILO standards.

Tuu Verified — Today
Tuu's verification framework evolved in 2025 from the Bamboo Badge model into Tuu Verified, a more structured KPI-corridor system spanning Hotels, Events and ISO 20121 readiness. Each verification cycle now produces a period-specific Evidence Pack, independently reviewed by HLB and registered on the Blockmark Registry, with eight scored operational KPIs across energy, water, waste, food and people.
Earlier Bamboo Badge verifications remain time-stamped and traceable through the Blockmark Registry.
