The United Nations coordinates its work with the funds, programmes, specialized agencies and other organizations of the UN System.
The United Nations itself is one part of the UN System. Cooperation between the UN and the other entities of the UN system is essential in order to achieve the purposes of the Organization laid out in the UN Charter.
Since its Charter was written, the United Nations has been mandated to do new work which was not envisioned at the time of its creation. The Organization has set goals to build a more sustainable world, and it has agreed to collective action to slow down climate change.
As the problems facing humanity have grown, the work of the United Nations has also grown.
