United Nations Secretariat

United Nations Secretariat is one of the six principal organs of the United Nations and serves as the organization's executive and administrative body. Established under the Charter of the United Nations, the Secretariat is responsible for carrying out the day-to-day work of the United Nations in accordance with mandates assigned by the United Nations General Assembly, the United Nations Security Council, the United Nations Economic and Social Council, the United Nations Trusteeship Council, and other United Nations bodies. Headed by the Secretary-General of the United Nations, the Secretariat provides administrative, technical, analytical, legal, and operational support to the Organization's programmes, conferences, peace operations, humanitarian activities, and international negotiations. Its principal headquarters are located at the United Nations Headquarters in New York City, with major offices in Geneva, Vienna, Nairobi, and numerous regional and country offices worldwide.

History

The United Nations Secretariat was established in 1945 following the entry into force of the Charter of the United Nations. The Charter designated the Secretariat as one of the Organization's principal organs and entrusted it with supporting the work of the newly created United Nations.

The Secretariat initially operated from temporary headquarters in London before relocating to temporary facilities in the United States. Upon completion of the United Nations Headquarters in New York City in the early 1950s, the Secretariat established its permanent headquarters there.

Since its creation, the Secretariat has expanded considerably in response to the growth of United Nations activities, including peacekeeping operations, humanitarian assistance, sustainable development, environmental protection, human rights, international law, and technical cooperation.

Legal framework

The Secretariat derives its authority primarily from the Charter of the United Nations, particularly Chapter XV (Articles 97–101), which establishes its organization, functions, and the status of its international civil servants.

Article 97 provides that the Secretariat shall comprise a Secretary-General and such staff as the Organization may require.

Articles 98 through 101 define the responsibilities of the Secretary-General, the appointment of staff, and the principles governing the independence and international character of the Secretariat.

Organization

The Secretariat is headed by the Secretary-General of the United Nations, who serves as the chief administrative officer of the Organization.

The Secretary-General is supported by:

Deputy Secretary-General
Under-Secretaries-General
Assistant Secretaries-General
Special Representatives and Special Envoys
Directors and senior administrative officials

The Secretariat consists of numerous departments, offices, regional commissions, programmes, and administrative units responsible for implementing mandates assigned by United Nations organs.

Departments and offices

It also supports the work of the United Nations regional commissions, including the United Nations Economic and Social Commission for Asia and the Pacific.

Functions and responsibilities

The Secretariat performs a broad range of executive, administrative, technical, and operational functions on behalf of the United Nations.

Its principal responsibilities include:

The Secretariat also assists Member States in implementing international agreements and United Nations resolutions.

International civil service

Staff members of the Secretariat constitute an international civil service rather than representatives of their respective national governments.

Under the Charter of the United Nations:

staff members are appointed on the basis of efficiency, competence, and integrity;
they are required to remain independent of national governments;
Member States undertake not to seek to influence staff in the discharge of their responsibilities;
staff members owe their allegiance exclusively to the United Nations.

The Secretariat employs personnel from a broad range of professional, technical, administrative, legal, scientific, and linguistic backgrounds.

Global presence

Although headquartered in New York City, the Secretariat maintains a global operational presence through offices and field missions around the world.

Major duty stations include:

The Secretariat also administers numerous peacekeeping operations, special political missions, regional commissions, and country offices across multiple continents.

Administrative responsibilities include:

financial management
procurement
human resources
information technology
conference services
facilities management
security
records management

The Secretariat is subject to oversight by the General Assembly, the Office of Internal Oversight Services, and the Board of Auditors (United Nations).

Challenges

The Secretariat faces a range of operational and institutional challenges, including budgetary constraints, increasing demands arising from peacekeeping and humanitarian operations, cybersecurity risks, administrative modernization, staff safety, and the coordination of complex multinational programmes.

It also operates in politically sensitive environments where balancing neutrality, efficiency, and the differing priorities of Member States may present significant administrative and diplomatic challenges.

Impact

Since 1945, the United Nations Secretariat has served as the administrative foundation of the United Nations, enabling the Organization to carry out its global responsibilities in peace and security, sustainable development, humanitarian assistance, human rights, international law, and international cooperation. Through its worldwide network of offices and personnel, the Secretariat supports diplomatic negotiations, technical cooperation, research, crisis response, and implementation of decisions adopted by the United Nations' principal organs. It remains one of the largest and most geographically dispersed international civil services in the world.
