The place which the climate change issue has in the institutions of the UN system is evaluated through the analysis of the role and activities of the major UN organs and bodies and the institutions of the UN system. The complexity of causes and consequences of climate change forms the
general framework of analysis and makes it necessary to include in the analysis a large number of
different UN bodies and organizations of the UN system. In addition to the major organs, the importance of those authorities and bodies that deal with climate change as their main activity is particularly perceived, and an overview is given of the importance of certain activities of specialized
agencies. Central part of the system consists of bodies formed by UN Framework Convention on
Climate Change, although the system of institutions dealing with climate change includes also various bodies formed on the basis of numerous other international agreements in the environmental
field. This situation places in a particularly sharp form the issue of implementation of international agreements by the member states, the willingness of member states to accept new responsibilities,
as well as the issue of coordination of actions of different stakeholders in this system. The efficiency
of taking actions is particularly emphasized and clues are given about the content of the activities of
individual subjects, character of obligations of the member states, problems concerning implementation of international treaties and the need to reform the system
