The International Maritime Organization (IMO) is the United Nations' specialized agency responsible for safety and security of international shipping and the prevention of pollution from ships. It acts as the global standard-setting authority for the safety, security, and environmental performance of shipping, developing a regulatory framework that aims for fairness, universal adoption, and consistent implementation. The organization is based in London, United Kingdom, at 4 Albert Embankment, and maintains a sizeable international staff to coordinate its worldwide membership of 176 Member States and three Associate Members, with its work aligned to the UN Sustainable Development Goals. Its core constituency includes member states and the broader shipping industry that rely on coherent rules to operate safely and with minimal environmental impact. In 2026, the IMO has been advancing the International Code of Safety for Maritime Autonomous Surface Ships, known as the MASS Code, signaling governance for emerging autonomous maritime operations. The body collaborates with other international organizations and partners to shape standards and support efforts toward decarbonization and safer global shipping.
