General Assembly 
Committee language: German

The General Assembly (for short UNGA) is the full assembly of the 193 member states of the UN. Each member state has one vote. Thus, the General Assembly is the most likely to live up to the principle of sovereign equality and the idea of giving all members a voice. The General Assembly meets annually at UN headquarters in New York City. 
The General Assembly may discuss practically any issue of international importance that is not dealt with by the Security Council. Its tasks also include the adoption of the UN budget (UN Charter Article 17) and the admission of new member states.

The decisions (resolutions) of the General Assembly are not binding under international law, but only of a recommendatory nature, but are usually taken in consensus with all member states, i.e. unanimously.
Only in internal organizational matters, such as the budget, can the General Assembly, as the supreme organ of the United Nations, take binding decisions.

United Nations Environment Programme (UNEP): 

Committee language: German
The United Nations Environmental programme was established in 1972 by UN Resolution 27/2997.

Its mission is to advance sustainable development worldwide and to act as a facilitator and stimulant for these goals.

One focus of UNEP's work are the Sustainable Development Goals, as well as monitoring progress towards a sustainable world.

UNEP acts as an interface between GOs and NGOs and is involved in the development of numerous international environmental programmes.

UNEP is based in Kenya, making it the only UN organisation headquartered in a developing country. The UN body of UNEP is the so-called Environment Assembly, which meets every two years and in which all UN member states are represented.

The Environmental Assembly develops, negotiates and adopts environmental protection programmes and forwards its decisions and recommendations to the General Assembly.

The Human Rights Council (HRC) ( for short HRC )

Committee language: English
The Human Rights Council of the UN (United Nations Human Rights Council, for short: UNHRC) is one of the subsidiary organs of the General Assembly and is the UN's main forum for cooperation on human rights (resolution 60/251).

 The Human Rights Council is obliged to meet at least three times a year and consists of 47 states elected by the General Assembly for a period of three years according to the regional group principle.

The main task of the HRC is to support states in meeting their human rights responsibilities and to make recommendations to the General Assembly regarding the further development of international law in the field of human rights.

To this effect, the UN Human Rights Council regularly reviews each UN member state as part of the Universal Periodic Review and can convene special procedures to deal specifically with a human rights situation in a state or a human rights issue. Other instruments of the HRC are the advisory committees and complaints procedures.

Der Sicherheitsrat (SC)  ( for short SC )
Committee language: English

The Security Council (Security Council) is the most powerful organ of the United Nations. The SC has " the primary responsibility for maintaining international peace and security" (UN Charter Article 24).
The Security Council consists of five permanent members (Permanent 5- P5) China, France, Great Britain, Russia, and the United States and ten non-permanent members (Elected 10 – E10). In order to pass a resolution, it needs the approval of nine members including all five permanent members. The "P5 states" thus enjoy a controversial veto right. Its resolutions are binding under international law, which is why the body is also considered the most powerful body in the United Nations.

The Security Council defines and decides whether there is a threat to or a breach of international peace in a particular situation. In order to secure peace, the Security Council can take on a mediating role or refer states to the International Court of Justice, but it can also impose a wide variety of sanctions, send UN peacekeeping troops (blue helmets) and authorise (humanitarian) interventions.
