What organization is a specialized agency of the United Nations responsible for regulating international shipping?

The International Maritime Organization, or IMO, is the specialized agency of the United Nations that is dedicated to regulating shipping and ensuring safe, secure, and efficient shipping on clean oceans. Established in 1948 and headquartered in London, the IMO plays a crucial role in developing a regulatory framework for the shipping industry, including safety standards, environmental protection measures, and the promotion of marine safety and efficiency.

One of the key functions of the IMO is to create international conventions that member states can adopt to harmonize security and safety standards across global shipping activities. This includes significant conventions such as the International Convention for the Safety of Life at Sea (SOLAS) and the International Convention for the Prevention of Pollution from Ships (MARPOL).

In contrast, the other organizations listed serve different purposes. The International Transport Workers' Federation (ITF) focuses on labor rights for transport workers rather than regulating shipping itself. UNESCO is involved in education, science, and culture, promoting international collaboration in these areas. The World Health Organization (WHO) is responsible for global public health and does not engage directly with shipping regulations, though it may address issues relevant to health on ships.

Thus, the IMO stands out as the definitive governing body for maritime regulation, making it the correct answer
