Non-violence: The strength of the courageous

The world is witnessing a troubling erosion of our shared humanity: dialogue is giving way to violence, civilians are bearing the brunt of conflict, and international law is being disregarded. In this time of rising tensions and deepening divisions, Mahatma Gandhi’s legacy of truth and non-violence carries renewed urgency. On this International Day of Non-Violence (2 October, Gandhi’s birthday), Secretary-General António Guterres calls on all people to follow Gandhi’s example—heal divisions through genuine dialogue and diplomacy, end suffering, and build a peaceful world through non-violence.

“Non-violence is not a weapon of the weak, it is the strength of the courageous.” - UN Secretary-General António Guterres.

Protecting girls’ futures: Adolescent pregnancy is preventable

For millions of girls, pregnancy can put health, education and dreams at risk. An estimated 12.3 million girls aged 10–19 gave birth in 2025, a UN Human Rights report finds. Poverty, gender inequality, child marriage and sexual violence heighten the risks, while stigma and barriers to healthcare leave many without support. Yet adolescent pregnancy is preventable. Comprehensive sexuality education, confidential healthcare, contraception and stronger protection can help girls make informed choices. The report urges governments to turn commitments into coordinated action, with girls helping shape the decisions that affect their futures.

Big crowds, rising heat: Planning saves lives

From sporting events to religious festivals, extreme heat can turn a day in the crowd into a health emergency. New World Health Organization (WHO) guidance shows that most heat-related illnesses at mass gatherings can be prevented or treated on site with timely planning. Well-organized medical teams can treat more than 90% of patients at venues, easing pressure on hospitals and ambulances. Safe drinking water, cooling areas, adjusted schedules and clear public information all help protect attendees, volunteers and workers. WHO urges governments and organizers to make heat safety part of every stage of event planning.

Tunisia's fishers find new safety nets

On Tunisia’s Djerba island, Fattouma Ben Chagra earns a steady income making and repairing traps for blue swimming crabs. But without a pension or insurance, she fears what will happen if the catch disappears. Tunisia has turned this invasive species into an economic opportunity, yet many fishing families remain exposed to illness, bad weather and uncertain earnings. The Food and Agriculture Organization of the United Nations (FAO) is helping explore ways to extend social protection to fishers and fish workers, linking sustainable fisheries with the security people need to build their futures.

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.

The Spotlight series

This series shines a light on communities facing conflict, displacement, public health emergencies and other humanitarian challenges around the world. Drawing on reporting from across the UN system, it amplifies voices from countries including Haiti, Gaza, DR Congo, Yemen, Afghanistan and Myanmar, to foster understanding, encourage engagement, and help mobilize support, assistance, and protection for the most vulnerable people.

Climate Change

Climate Change is one of the defining issues of our time and we are at a pivotal moment. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. Taking decisive action today will make adapting to these impacts in the future more effective and less costly.

After Nepal’s floods, finding strength amid loss

In a crowded shelter in Nepal, 20-year-old Ram Maya replays her mother’s last voice message, asking if she was safe. The floods took her mother and sister-in-law; now she finds strength in cooking for displaced families and caring for children who lost their parents. Other women fled carrying babies, watched their homes vanish and faced life without clean clothes or privacy. The United Nations Population Fund (UNFPA) is providing hygiene supplies, healthcare and counselling to help survivors regain comfort and dignity. For women grieving loved ones and caring for their families, surviving the flood is only the beginning.

Small changes, less plastic: The people rethinking tourism

For Lay, Valy and Rumluek, cutting plastic waste means protecting the places people call home and the livelihoods tourism sustains. In Cambodia, Lay replaced bottled water in his hotels with reusable glass containers. In Lao PDR, Valy helps coffee drinkers borrow and return stainless steel cups. On Thailand’s Koh Tao island, Rumluek brings businesses together to reduce waste and protect the sea that supports local jobs. Their practical solutions show how everyday choices can keep plastic out of the environment. With support from the United Nations Development Programme, local innovators are helping tourism leave a lighter footprint.
