Which organization primarily governs international tourism?

The United Nations World Tourism Organization (UNWTO) is the primary governing body for international tourism. Its main role is to promote and facilitate the growth of tourism worldwide, making it a crucial player in the development of sustainable and responsible tourism policies. The UNWTO provides leadership and support to countries and stakeholders in the tourism sector, offering guidelines, research, and resources that help shape the global tourism landscape. It also aims to enhance the understanding of tourism's contributions to economic growth, job creation, and sustainable development.

The other organizations mentioned have important roles but focus on different aspects of tourism. The World Health Organization (WHO) primarily deals with global public health and does not govern tourism itself. The International Air Transport Association (IATA) focuses specifically on the airline industry, regulating and advocating for airline operations and passenger travel but does not govern tourism as a whole. The World Travel and Tourism Council (WTTC) represents the private sector in tourism and provides data to inform industry practices, but it is not a governing body like the UNWTO. Thus, the UNWTO stands out as the main organization responsible for the governance and promotion of international tourism.
