Equal parts diplomat and advocate, civil servant and CEO, the Secretary-General is a symbol of United Nations ideals and a spokesman for the interests of the world's peoples, in particular the poor and vulnerable among them. The current Secretary-General, and the ninth occupant of the post, is Mr. António Guterres of Portugal, who took office on 1 January 2017.
The Charter describes the Secretary-General as "chief administrative officer" of the Organization, who shall act in that capacity and perform "such other functions as are entrusted" to him or her by the Security Council, General Assembly, Economic and Social Council and other United Nations organs. The Charter also empowers the Secretary-General to "bring to the attention of the Security Council any matter which in his opinion may threaten the maintenance of international peace and security". These guidelines both define the powers of the office and grant it considerable scope for action. The Secretary-General would fail if he did not take careful account of the concerns of Member States, but he must also uphold the values and moral authority of the United Nations, and speak and act for peace, even at the risk, from time to time, of challenging or disagreeing with those same Member States.
That creative tension accompanies the Secretary-General through day-to-day work that includes attendance at sessions of United Nations bodies; consultations with world leaders, government officials, and others; and worldwide travel intended to keep him in touch with the peoples of the Organization's Member States and informed about the vast array of issues of international concern that are on the Organization's agenda. Each year, the Secretary-General issues a report on the work of the United Nations that appraises its activities and outlines future priorities. The Secretary-General is also Chairman of the United Nations System Chief Executives Board for Coordination (CEB), which brings together the Executive Heads of all UN funds, programmes and specialized agencies twice a year in order to further coordination and cooperation in the entire range of substantive and management issues facing the United Nations System.
One of the most vital roles played by the Secretary-General is the use of his "good offices" -- steps taken publicly and in private, drawing upon his independence, impartiality and integrity, to prevent international disputes from arising, escalating or spreading.
Each Secretary-General also defines his role within the context of his particular time in office.
