TUI sustainability score: 26/100
TUI is a global tourism and travel group headquartered in Hanover, Germany, operating airlines, cruise ships, hotels, and tour packages across 180 destinations. The company serves approximately 27 million customers annually and is one of Europe's largest integrated travel operators, though heavily reliant on aviation and cruise—carbon-intensive sectors.

TUI discloses emissions across most scopes but omits material Scope 3 categories, particularly customer travel. Airline targets are intensity-based, masking absolute emission growth risks. A Hamburg court found a TUI Cruises net-zero advertising claim misleading, and the Dutch Advertising Board separately upheld a complaint over TUI's 'Fair Friday' campaign. Trade association misalignment on climate policy compounds weak governance.
TUI scores 26/100 (Significant gaps) on SINK's independent climate assessment, scored from public data only. Scores are free. Companies can never pay for anything about their own score. Last verified July 2026.
