The UN system is mainly financed through assessed and voluntary contributions from Member States. The UN Specialized Agencies are funded partly through assessments and voluntary contributions. The course will go through the Regular Budget, the Peacekeeping Budget, and the international tribunals’ budget, which are funded through assessments. Also, this course will explore how the UN Programmes and Funds are financed through voluntary contributions from Member States. The participation of UN officials and elected chairs of the ACABQ and JIU, as well as the role of those institutions in the budget delivering process is of paramount importance to new delegates. The Fifth Committee as a General Assembly specialized policy making process is a critical part of understanding the UN Budget System.
