What is one of the main roles of the World Tourism Organization (UNWTO)?

The World Tourism Organization (UNWTO) plays a vital role in promoting sustainable tourism development globally. This focus on sustainability is crucial, as the organization advocates for practices that not only enhance the economic benefits of tourism but also consider the social and environmental impacts. By encouraging tourism that conserves resources and benefits local communities, the UNWTO aims to create a positive and lasting impact on destinations around the world.

This objective aligns with widespread global initiatives and agreements aimed at fostering responsible and sustainable tourism practices, ensuring that tourism contributes to sustainable development goals. The promotion of sustainable tourism helps mitigate negative effects such as environmental degradation and cultural erosion, making it a key focus area of the UNWTO's mission.

The other options do not accurately reflect the UNWTO's primary focus. Regulation of national tourism boards, management of international travel restrictions, and providing travel insurance fall outside the purview of the organization's central objectives.
