Securing the Mission: How the UN Budget and Agencies are Financed

The UN is funded in two main ways:

  1. Assessed Contributions (Mandatory): These are compulsory payments from Member States to fund the core UN budget (covering operational costs, peace missions, etc.).
    The amount each country pays is based on a complex formula that considers factors like Gross National Income (GNI), population, and a country’s debt situation.
  2. Voluntary Contributions: These are funds donated by Member States and other partners (e.g., private sector, NGOs) for specific UN programs, funds, and specialized agencies (like UNICEF, UNDP, and the World Food Programme).
    Most of the UN’s humanitarian and development work is funded through these voluntary contributions.

The Power to Decide: UN Voting in the General Assembly and Security Council

Voting mechanisms differ between the main bodies:

1. General Assembly (GA)

United Nations General Assembly

  • Structure: Composed of all 193 Member States, each with one vote.
  • Voting:
    • Simple Majority: Decisions on routine matters are passed by a simple majority (more than half) of members present and voting.
    • Two-Thirds Majority: Decisions on important questions—such as recommendations on peace and security, admission of new members, or budgetary matters—require a two-thirds majority of members present and voting.
  • Impact: GA resolutions are not legally binding on governments, but they carry the moral authority and weight of world opinion.

2. Security Council (SC)

United Nation Security Council

  • Structure: 15 Member States: 5 permanent members (China, France, Russian Federation, United Kingdom, and the United States) and 10 non-permanent members elected for two-year terms.
  • Voting:
    • Procedural Matters: Require an affirmative vote of at least 9 members.
    • Substantive Matters (e.g., sanctions, peacekeeping): Require an affirmative vote of 9 members, including the concurring votes of all five permanent members. A single negative vote by any of the five permanent members constitutes a veto, blocking the resolution.


Saving Lives Worldwide: The UN’s Critical Humanitarian Impact

Humanitarian action is one of the most visible and impactful aspects of the UN’s work, typically led by agencies like the World Food Programme (WFP), UNICEF, and the UN Refugee Agency (UNHCR). Key areas include:

  2. Refugee Protection and Aid: Offering protection, shelter, and basic necessities to refugees and internally displaced persons fleeing persecution and conflict.
  3. Child Welfare and Health: Conducting global vaccination campaigns, providing nutritional support, and promoting children’s rights and education in vulnerable areas.
