During the last decade, the Global Environment Facility (GEF) has provided more than US$1 billion for more than 270 climate change-related projects in 120 countries. Not counting enabling activities and some short-term measures, 120 of those projects in 60 countries demonstrate an impressive range of approaches to promoting energy efficiency, renewable energy, and (to a lesser extent) sustainable transport. The overall objective of the Climate Change Program Study was to assess the achievements of GEF-financed climate change operational programs.
