The Central Service is a hub of functions that provides support services for UNGSC internal operations, such as finance, human resources, procurement, property management, conference and learning services, facilities management, security and other campus support activities, while operationalizing special programmes for the Secretariat and United Nations field missions in the area of occupational health and safety. The Central Service acts in an enabling role, to allow the two service delivery pillars, namely Service for Geospatial, Information and Telecommunications Technologies (SGITT) and Supply Chain Service (SCS), as well as the several tenant units, to deliver their operational mandates.
The Central Service is the advisory pillar supporting the Director UNGSC on strategic and managerial matters related to the organization.
