Since the late 1990s there have been many calls for reforms of the United Nations (UN). However, there is little clarity or consensus about what reform might mean in practice. Both those who want the UN to play a greater role in world affairs and those who want its role confined to humanitarian work or otherwise reduced use the term "UN reform" to refer to their ideas. The range of opinion extends from those who want to eliminate the UN entirely, to those who want to make it into a full-fledged world government. Secretaries-General have presented numerous ways to implement these new reforms. There have been reform efforts since the creation of the UN and closely associated with each of the Secretaries-General.

Proposals for the creation of a United Nations Environmental Organization (UNEO) have come as some question the efficacy of the current United Nations Environment Programme (UNEP) at dealing with the scope of global environmental issues. Created to act as an anchor institution in the system of Global Environmental Governance (GEG), it has failed to meet those demands. The UNEP has been hindered by its title as a Programme as opposed to a specialized agency like the United Nations Educational, Scientific and Cultural Organization (UNESCO) or the World Health Organization (WHO), in addition to a lack of voluntary funding, and a location removed from the centers of political power, in Nairobi, Kenya. These factors have led to widespread calls for UNEP reform, and following the publication of Fourth Assessment Report of the IPCC in February 2007, a "Paris Call for Action" read out by French President Chirac and supported by 46 countries, called for the UNEP to be replaced by a new and more powerful United Nations Environment Organization, to be modelled on the World Health Organization. The 52 countries included the European Union nations, but notably did not include the United States and BRIC, the top five emitters of greenhouse gases.
An international organization, also known as an intergovernmental organization or an international institution, is an organization that is established by a treaty, or is an instrument governed by international law and possessing its own legal personality, such as the United Nations, the World Health Organization, International Union for Conservation of Nature, and NATO.

Additionally, entities may hold observer status. An alternative definition is that an international organization is a stable set of norms and rules meant to govern the behavior of states and other actors in the international system.
