This paper examines the transformative role that artificial intelligence can take in the post-pandemic era in the development of sustainable tourism. From applications in environmental monitoring, resource optimization, carbon footprint reduction, waste management, and developing personalized sustainable experiences, AI can be seen as a crucial enabler of tourism in tune with ecological goals. Besides, the paper mentions challenges such as costs, technical barriers, and ethical ones, keeping in mind balanced implementation approaches. In any case, AI, from the perspective of sustainable tourism, opens opportunities for the protection of ecosystems and experiences for visitors.
