TripAdvisor, the world's largest on-line community of travellers, and UNESCO launched a partnership on Thursday to mobilize travellers' support to preserve natural and cultural sites inscribed on UNESCO's World Heritage List.

At the launch of the partnership, TripAdvisor founder and Chief Executive Officer, Stephen Kaufer, pledged to donate up to US$1.5m of support over the next two years to UNESCO's World Heritage Centre.
