Objectives:
The study examines legal and institutional regulations governing the tourism sector in the context of global crises such as the COVID-19 pandemic, war (e.g., the war in Ukraine), and climate change. Global crises (pandemic, war, climate change) necessitate a flexible and integrated approach to tourism regulation, while states and international organisations are not yet sufficiently prepared to provide coherent, crisis-resilient legal frameworks in this field. Research objectives: 1. To analyse tourism regulations in selected states and international organisations against the backdrop of the three major crises. 2. To assess the impacts of the pandemic, war, and climate change on the tourism sector and how they are reflected in public policies and legal instruments. 3. To identify gaps and challenges in the existing regulatory frameworks

Material and methods:
The study combines doctrinal legal analysis with a functional comparative approach to the solutions adopted by the UN, the EU, and Poland. It further employs an empirical analysis of datasets produced by UN, EU, and Polish agencies

Results:
Global crises — pandemic, war, and climate — have revealed the fragmented and reactive nature of tourism regulations. Effective governance requires clear legal bases for restrictions, stronger EU-level coordination, and efficient crisis management tools.

Conclusions:
Priorities include travel safety, resilient mobility chains, and reinforced passenger rights. In the long term, regulation must align with climate goals through decarbonization, nature protection, and credible sustainability standards, supported by enforceability, funding, and cooperation with local authorities.
