ECOSOC, one of the six main organs of the United Nations established by the UN Charter in 1946, is the principal body for coordination, policy review, policy dialogue, and recommendations on economic, social and environmental issues, as well as for implementation of the internationally agreed development goals. ECOSOC serves as the central mechanism for the activities of the United Nations system and its specialized agencies and supervises the subsidiary and expert bodies in the economic, social and environmental fields. It works to promote sustainable development, build partnerships, engage the youth in economics and advance the integration of economic and social policies.
