The Global Environment Facility is replenished by donors every four years. Ideally, any replenishment should
be based on the achievements so far and the problems that need to be addressed in the coming years. The
fourth replenishment, which will be negotiated and agreed in the second half of 2005, will be informed on the
achievements of the GEF through the present “Overall Performance Study,” which is the third of its kind. It
provides an overview of the results in dealing with global environmental problems and it also looks at how
the GEF functions as a network and partnership of institutions and organizations.
