Clean air: Supporting health and the economy

Air pollution has long contributed to death and disease, while undermining economic prospects and community well-being. Many sources of air pollution, such as the burning of fossil fuels and biomass, also contribute to greenhouse gas emissions, causing our planet to warm. This year’s International Day of Clean Air for blue skies (7 September) emphasizes the undeniable economic case of integrated climate and clean air action to support healthier populations and economic prosperity. Join the observance by sharing your actions on social media using the hashtag #CleanAirDay.

Beyond 1.5°C: every fraction matters

The world is likely to cross the 1.5°C global warming threshold within the next few years, increasing the risks of extreme weather, ecosystem loss and damage to health, food and water supplies. A new UN Environment Programme report says the best remaining path is to keep this rise as small and brief as possible, then bring temperatures back below 1.5°C. This requires rapid and sustained cuts in greenhouse gas emissions, a faster shift from fossil fuels to renewable energy, stronger climate adaptation and carefully managed removal of carbon from the atmosphere. Every fraction of a degree — and every year above 1.5°C — matters.

Still searching, still asking: Where are they?

Across the world, families of people who have disappeared continue to live with the same unanswered question: Where are they? Enforced disappearances leave relatives facing years of uncertainty while they search for truth, justice and accountability. Families and civil society groups often lead these efforts, despite facing threats, harassment and other obstacles. The UN Human Rights Office stresses that States must investigate disappearances, search for missing people and ensure victims’ rights to truth, justice and reparation. Preventing future disappearances also requires stronger action, accountability and international cooperation.

Singing through Mongolia’s harsh winters

In Mongolia’s Töv province, dairy farmer Otgo Dashdorj sings to keep her cows calm — and producing more milk. After 27 years as nomadic herders, she and her husband settled three years ago as harsher winters, drought and degrading grasslands made traditional herding increasingly difficult. Now, with support from the Food and Agriculture Organization and partners, Otgo is using better feed, digital tools and climate-smart farming practices to strengthen her business. She hopes to double her herd to 40 cows and eventually pass the farm — and her secret of singing to happy cows — to her veterinarian son.

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.

There’s no problem that can’t be solved (AAN S13-E12)

“I've seen countries take their future in hand and transform themselves. [...] So I know that's possible. I'm also convinced that there was no problem that we have in Haiti, for which there's not a proven solution.”

Garry Conille knows that resilience, hope and determination can be powerful foundations for change. Now UN Resident Coordinator in Kenya, he hopes to contribute his wide-ranging experience to help accelerate the country’s development. 

Meanwhile, he hasn’t let go of his brimming optimism towards his troubled home of Haiti, where he served as prime minister. “It's been years of challenges and stress and distress, yet when you walk in the streets of Haiti, you will see these young children with their hair just tightly done, and these uniforms tightly pressed, walking for hours to go to school. [That’s] what defines Haiti more than anything else.”

The UN and its agencies stand alongside all low and middle income countries as they work to improve the lives of their citizens and those who seek shelter within their borders. In this episode, Garry Conille reflects on the dangers faced by young migrants, on the promise of Kenya as a new hub for diplomacy, and about his drive to seek solutions for even the most intractable problems.

Hope against Ebola

In eastern Democratic Republic of the Congo, health workers and community responders are fighting Ebola while facing conflict, displacement and limited resources. Some are displaced themselves, yet continue caring for patients, identifying suspected cases and helping communities understand how to protect themselves. At a transit centre serving a displacement site of 18,500 people, responders provide testing and early care, helping contain the virus before it spreads further. Their local knowledge and trusted relationships are also crucial to overcoming fear and misinformation.

Protecting the Amazon, protecting the climate

The Amazon is one of the world’s most important allies against climate change, storing vast amounts of carbon while supporting extraordinary biodiversity and millions of people. But deforestation, fires and other pressures are weakening its ability to regulate the climate and could push parts of the forest towards irreversible change. Protecting and restoring the Amazon means stopping forest loss, supporting sustainable livelihoods and recognizing the crucial role of Indigenous Peoples and local communities. Stronger national climate plans and international cooperation can help safeguard the forest — and the climate benefits it provides far beyond the region.
