This paper explores the concept of metaversal sustainability within the framework of sustainable tourism. It aims to address the novel phenomenon of tourism in the metaverse and analyze scenarios that could influence the resilience of the sustainable tourism paradigm in response to this new phenomenon. Based on Kuhn's paradigmatic framework, the paper offers an innovative perspective on integrating new theories and practice-relevant phenomena, emphasizing the relevance and commensurability of different paradigmatic dimensions. The findings highlight that the 21st-century metaverse tourism poses a new challenge to the traditional sustainable tourism paradigm, which traditionally focuses on the economic and ecological sustainability of the physical environment. Adopting a metaversal sustainability scenario for virtual and mixed reality is crucial for responsible implementation of the sustainable tourism development paradigm, considering all environments, whether fantastic or realistic. The study acknowledges the limitations of metaverse tourism being in an experimental phase and the evolving understanding of the metaverse. However, it suggests practical implications for tourism policy and practice, emphasizing the need for stakeholders to adapt to the changing tourism landscape by recognizing the metaverse as a viable environment committed to sustainable development. Social implications include the potential of the metaverse to transform social perception and behavior, advocating for sustainable development in all environments where people live and explore. The originality and value of the research lie in its pioneering role in advancing a sustainable tourism paradigm that goes beyond traditional planetary dimensions, proposing a path towards a more holistic and future-oriented approach. The term "metaversal sustainability" contributes to the lexicon of paradigms for both tourism and societal sustainable development.This paper explores the concept of metaversal sustainability within the framework of sustainable tourism.
