Celebrating migrants and their stories of resilience and possibility

Migration is shaping our world in profound and lasting ways. From driving economic growth and innovation to strengthening communities and sustaining development, human mobility is a defining force of the 21st century. International Migrants Day 2025 (18 December) celebrates migrants for their economic contributions, resilience, skills, and stories, recognizing the strength, leadership, and courage they bring to societies everywhere. On this day, let us stand together to protect the rights of every migrant and ensure that migration is safe, dignified, and empowering for all.

A healthier planet isn’t just a dream, it’s a trillion-dollar opportunity

Climate change, biodiversity loss, and pollution already cost trillions annually, warns a new United Nations Environment Programme report. But systemic transformation, circular economies, clean energy, sustainable agriculture, could unlock $20 trillion yearly by 2070, save nine million premature deaths, and lift millions from poverty and hunger. Investing $8 trillion a year until 2050 secures a thriving planet and economy. However, the cost of inaction is far higher.

Progress toward universal health coverage, but billions still left behind

Since 2000, nations have advanced toward universal health coverage, more care, and less financial strain. Yet billions still lack essential services, and millions are pushed deeper into poverty by out-of-pocket costs, largely for medicines. A new study from the World Health Organization-World Bank warns: without bold investment, by 2030 many will still face hardship. Health is a right, but for too many, it remains a distant promise.

From Himalayan mountain tops to Milan catwalks

In the Himalayan mountains of Bhutan, women in the village of Goenpa Kabab weave intricate silk Kishuthara dresses on backstrap looms, a skill passed down through generations in a Buddhist, matriarchal community. Sherab Tshomo, a 41-year-old artisan, has been perfecting this craft since age eight, which involves dyeing raw silk with local plants and using traditional methods to create detailed patterns. Despite the high value of these garments within Bhutan and abroad, many women artisans struggle to access international markets, including the global fashion industry, to showcase their artistry and heritage.

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.

A trapeze without a net: the life of the UN Spokesperson

“It's [a] trapeze without a net, in a sense, because you're representing ... the Secretary General, you're representing the UN as a whole. And you have to be prepared, and sometimes you don't have the answer.”

Every day at noon, Stéphane Dujarric steps on stage to field questions about the United Nations from international journalists. As spokesman for the Secretary-General, he must be ready to talk on all aspects of the organization’s work at a time of unprecedented financial and political strain.

“There is no way we can move forward in this world without multilateralism, without an organization like this one. It's like a plant, right? It needs to be watered. We can't let it wither away.”

An alumnus of the United Nations International School, Stéphane Dujarric was immersed in the world of international diplomacy from an early age. In this episode of Awake at Night, he shares why his own family owes everything to the actions of two courageous diplomats, and reflects on how being a procrastinator can be a superpower when faced with the challenge of the 24-hour news cycle.

365 Days of transition in Syria

On 8 December 2024, the people of Syria woke to the news that marked the end of 14 long years of deadly conflict. Syrians began returning to the places they once called home. Despite the challenges, hope prevails. For several days a United Nations Office for the Coordination of Humanitarian Affairs (OCHA) team travelled across the country, meeting families who had recently returned after long years of displacement within Syria and beyond its borders. Here are their stories.
