AI and Sustainability are hotly debated topics in travel. But how might new policies and regulations in these areas impact future interactions between travellers, suppliers, booking platforms and governments? This week, Gary and Hannah discuss the current landscape for OTAs, sustainability and AI policy development with Yang Li, Head of Public Affairs, Asia Pacific, at Booking.com. Which ASEAN and APAC countries are developing structured legal frameworks around sustainability? And how prepared are businesses region-wide for the EU Greenwashing Claims Directive, which is due to enter into force in 2026? Yang selects some key findings from Booking.com's 9th global Sustainability Report, and their applicability to ASEAN markets. We also touch on sustainable tourism target setting, certifications and investment, and the current state of the Intention vs Action gap. Plus, what are 'closed loop' AI trip-planning tools, and how are travellers using them? How will the interface between OTAs and AI agents shape up? And will Asian governments continue their light touch approach to AI regulation, or are new legal frameworks on the horizon?
