Emissions Gap Report 2026: The Point of Return

Against a backdrop of intensifying climate impacts and geopolitical tensions, the new UNEP Emissions Gap Report examines the gap between current efforts to cut emissions and the action needed to meet the Paris Agreement's long-term temperature goal. While the clean energy transition is accelerating due to lower costs and concerns over energy security, affordability, and industrial competitiveness, global action remains insufficient to avoid the worst risks of climate change. "And the world is running out of time and excuses to close it," said the UN Secretary-General, calling on governments to take action.

The world's immediate priority is to limit any overshoot of 1.5°C and bring temperatures back to 1.5°C by the end of the century.

After 14 years of war, Syrians seek truth and justice

For more than a decade, Samah Almardini has searched for answers about her missing brother. Her story reflects the anguish of thousands of Syrian families seeking justice after 14 years of conflict that displaced more than 13 million people. As Syria begins rebuilding, survivors are demanding accountability, answers about the disappeared and support for former detainees. With UN Human Rights assistance, new national institutions are advancing Syrian-led transitional justice efforts, including investigations and trials. But lasting peace requires more than rebuilding homes: it means confronting past abuses, restoring dignity and ensuring they never happen again.

Global poverty rises for the first time in 16 years

For millions of families, poverty means more than a lack of income. It means going without food, clean water, electricity or education — often all at once. The 2026 Global Multidimensional Poverty Index reveals that nearly 1.2 billion people face overlapping hardships, with children accounting for almost half. For the first time in 16 years, global multidimensional poverty is rising. Yet progress is possible: 33 countries have halved their poverty index values in less than 15 years. The United Nations Development Programme calls for urgent action to reverse setbacks and ensure a life of dignity for all.

Turning development into jobs and opportunity

A young person finding their first job. A small business expanding. A farmer protecting their livelihood from drought. These are the real measures of development. The World Bank Group’s latest Scorecard highlights how investments in education, healthcare, electricity and financial services are helping create opportunities worldwide. From renewable energy in Uzbekistan to small business financing in Ecuador, progress is taking shape. Yet shrinking aid budgets, rising debt and climate shocks threaten these gains. The challenge now is to turn institutional reforms into more and better-paid jobs, especially for those most at risk of being left behind.

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:

A UNIFIL peacekeeper from Spain on a regular patrol in the vicinity of Al Wazzani, south-eastern Lebanon as the sun sets in the horizon. Since 1948, more than a million women and men have served as UN peacekeepers.

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.

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.

Blazing new trails for nature and opportunity in Armenia

Emma Petrosyan almost gave up on her dream of turning cycling into a force for nature conservation in Armenia. Instead, with support from a UNDP-implemented programme, she created the country's first mountain bike park in Vanadzor, transforming degraded forests into trails for ecotourism and environmental education. Since opening in 2023, Boo Mountain Bike Park has welcomed more than 45,000 visitors, creating jobs for young people while protecting biodiversity. Her journey shows how one woman's determination, backed by international support, can turn a local idea into a model for sustainable development.

Protecting childhood, one girl at a time

Married at 16, Fatou Bah was determined her daughters would have a different future. Today, she helps protect other girls from child marriage in The Gambia. Through United Nations Population Fund-supported initiatives, mothers’ clubs, religious leaders and community advocates are challenging harmful traditions, keeping girls in school and defending their right to choose their future. With thousands of girls still at risk, their message is clear: “Marriage should never be the reason her childhood ends.”
