Invest in clean air now

Air pollution is the biggest environmental health risk of our time. It worsens climate change and causes economic losses. It knows no borders – everyone has a responsibility to protect our atmosphere and ensure healthy air for all. By collaborating across borders, sectors, and silos, we can reduce air pollution through collective investments of time, resources and efforts. This International Day of Clean Air for Blue Skies (7 September), we call upon everyone to Invest in #CleanAirNow. By tackling air pollution proactively, we can achieve transformative change and secure healthy air for all.

Maintain International 探花精选 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.

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.

Improving people’s well-being continues to be one of the main focuses of the UN.

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.

Climate change, conflict, political instability, disease and economic shocks are driving humanitarian needs in the Southern and Eastern Africa region. At least 74 million people in the region need humanitarian assistance - that's the highest number of people in need in the world. This number is expected to increase by the end of the year due to climate change and conflict. Displacement and food crises, a high incidence of cholera and a growing number of violent sexual assaults are among the most serious challenges facing this area of the African continent.

As we celebrate , here’s a look at some of the relationships and initiatives from around the world that contribute to empowering and protecting women and girls.
