The United Nations at 80: Building our future together

United Nations Day (24 October) marks the anniversary of the day in 1945 when the United Nations Charter entered into force. UN Day, celebrated every year, offers the opportunity to amplify our common agenda and reaffirm the purposes and principles of the UN Charter that have guided us for the past 80 years. Eight decades after its founding, the Organization confronts challenges of staggering scale. Now, more than ever, the world must recommit to solving problems no nation can solve alone. On this UN Day, let’s stand together and fulfil the extraordinary promise of your United Nations.

Beyond money: Unmasking the many faces of global poverty

In a world where the shadows of inequality loom large, the Multidimensional Poverty Index illuminates the complex tapestry of acute poverty affecting over 100 developing nations. The latest report examines climate hazards impacting 1.1 billion multidimensionally poor people, with 43.6% living in severe poverty, meaning they are deprived of 50 percent or more of the necessities of a dignified life. Children are disproportionately affected, with 27.8% facing multidimensional poverty, representing over half of the total. Most of the poor reside in countries with low or medium human development, with significant numbers in sub-Saharan Africa and South Asia. Notably, poverty also persists in middle-income countries, affecting millions.

Massimo Bottura: Fighting food waste by “creating beauty through respect”

Food waste isn’t just what’s scraped off plates, it’s a quiet crisis echoing through our climate, economies, and the lives of millions who go hungry. The 2024 Food Waste Index reveals that 19% of consumer-available food is wasted, causing emissions five times higher than aviation, while a third of humanity faces food insecurity. Yet, individuals and communities can act creatively. Chef Massimo Bottura, UNEP Goodwill Ambassador, leads the Food for Soul initiative, turning surplus food into meals at “Refettorios” in nine countries—showing that fighting waste is both responsible and beautiful.

What we do

Due to the powers vested in its Charter and its unique international character, the United Nations can take action on the issues confronting humanity in the 21st century, including:

Maintain International Peace and Security

The United Nations came into being in 1945, following the devastation of the Second World War, with one central mission: the maintenance of international peace and security. The UN does this by working to prevent conflict; helping parties in conflict make peace; peacekeeping; and creating the conditions to allow peace to hold and flourish. These activities often overlap and should reinforce one another, to be effective. The UN Security Council has the primary responsibility for international peace and security. The General Assembly and the Secretary-General play major, important, and complementary roles, along with other UN offices and bodies.

Protect Human Rights

The term “human rights” was mentioned seven times in the UN's founding Charter, making the promotion and protection of human rights a key purpose and guiding principle of the Organization.  In 1948, the Universal Declaration of Human Rights brought human rights into the realm of international law.  Since then, the Organization has diligently protected human rights through legal instruments and on-the-ground activities.

Deliver Humanitarian Aid

One of the purposes of the United Nations, as stated in its Charter, is "to achieve international co-operation in solving international problems of an economic, social, cultural, or humanitarian character."  The UN first did this in the aftermath of the Second World War on the devastated continent of Europe, which it helped to rebuild.  The Organization is now relied upon by the international community to coordinate humanitarian relief operations due to natural and man-made disasters in areas beyond the relief capacity of national authorities alone.

Promote Sustainable Development

From the start in 1945, one of the main priorities of the United Nations was to “achieve international co-operation in solving international problems of an economic, social, cultural, or humanitarian character and in promoting and encouraging respect for human rights and for fundamental freedoms for all without distinction as to race, sex, language, or religion.”  Improving people’s well-being continues to be one of the main focuses of the UN. The global understanding of development has changed over the years, and countries now have agreed that sustainable development offers the best path forward for improving the lives of people everywhere.

Uphold International Law

The UN Charter, in its Preamble, set an objective: "to establish conditions under which justice and respect for the obligations arising from treaties and other sources of international law can be maintained."  Ever since, the development of, and respect for international law has been a key part of the work of the Organization.  This work is carried out in many ways - by courts, tribunals, multilateral treaties - and by the Security Council, which can approve peacekeeping missions, impose sanctions, or authorize the use of force when there is a threat to international peace and security, if it deems this necessary.  These powers are given to it by the UN Charter, which is considered an international treaty.  As such, it is an instrument of international law, and UN Member States are bound by it.  The UN Charter codifies the major principles of international relations, from sovereign equality of States to the prohibition of the use of force in international relations.

Structure of the
United Nations

The main parts of the UN structure are the General Assembly, the
Security Council, the Economic and Social Council, the Trusteeship Council, the International Court of Justice, and the UN Secretariat. All were established in 1945 when the UN was founded.

General Assembly

The General Assembly is the main deliberative, policymaking and representative organ of the UN. All 193 Member States of the UN are represented in the General Assembly, making it the only UN body with universal representation.

Security Council

The Security Council has primary responsibility, under the UN Charter, for the maintenance of international peace and security. It has 15 Members (5 permanent and 10 non-permanent members). Each Member has one vote. Under the Charter, all Member States are obligated to comply with Council decisions.

Economic and Social Council

The Economic and Social Council is the principal body for coordination, policy review, policy dialogue and recommendations on economic, social and environmental issues, as well as implementation of internationally agreed development goals.

Trusteeship Council

The Trusteeship Council was established in 1945 by the UN Charter, under Chapter XIII, to provide international supervision for 11 Trust Territories that had been placed under the administration of seven Member States, and ensure that adequate steps were taken to prepare the Territories for self-government and independence.

International Court of Justice

The International Court of Justice is the principal judicial organ of the United Nations. Its seat is at the Peace Palace in the Hague (Netherlands). It is the only one of the six principal organs of the United Nations not located in New York (United States of America).

Secretariat

The Secretariat comprises the Secretary-General and tens of thousands of international UN staff members who carry out the day-to-day work of the UN as mandated by the General Assembly and the Organization's other principal organs.

As ceasefire takes hold, Gaza’s bakeries fire up to fight hunger

Deliveries of fresh flatbread in Gaza reach the population, offering a sense of normality as the ceasefire takes hold. The bakeries offer a tangible sign that a precarious normality is returning. The loaves rolling out of their fiery ovens are part of a massive and rapid scale-up of WFP food assistance for people facing severe and even catastrophic hunger - with the aim of feeding up to 1.6 million in the first three months. Trucks of WFP food assistance now entering the Strip are supporting bakeries, nutrition programmes and general food distributions. Those distributions will expand as conditions allow more food to enter the Strip and bakeries to reopen. Tens of thousands of metric tonnes of our food are ready for dispatch or heading to the Strip. “The smell of bread gives people hope that things are going to get back to normal,” says Samer Abdeljaber, WFP Regional Director for the Middle East, North Africa & Eastern Europe. As more food reaches hungry people, he adds, “anxiety levels go down, so they can trust that more food is going to come in the next days.”
