TUI scores 26/100 (Significant gaps) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified July 2026.
That places TUI joint 677th of 809 companies scored, and joint 6th of 23 in Airlines / Aviation.
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.
