The now defunct United Nations Centre for Urgent Environmental Assistance (UNEP/UNCUEA) worked to coordinate international response to man-made disasters. It was administrated by the United Nations Environmental Programme.
Background
UNCUELA operations were initially run by a small staff located in a Swiss government office in Geneva, Switzerland. Later, it was relocated to offices inside the International Environment House, found in Châtelaine.
The short-lived Centre was created to respond to an initiative proposed by Mikhail Gorbachev in the late 1980s. However, it never received necessary support due to criticism that it overlapped with already-existing agencies, like the International Maritime Organization and the International Atomic Energy Agency.
