The main purpose of this evaluation was to assess UNDP's positioning and contributions to managing environment and energy for sustainable development. The scope of the evaluation covered all programmatic and operational aspects of the environment and energy area in all UNDP's geographic regions and at the global, regional and country levels. The evaluation primarily focused on the period from 2002 to 2007. However, the evaluation also considered how events before this period shaped UNDP's approach to environment and energy. Building upon an independent and objective analysis of the past, the evaluation has provided perspectives towards how UNDP is positioned to move forwards in its environment and energy work.
