The climate change program study evaluates performance and results, and how results were achieved. Given the size of the GEF portfolio and the need to identify overall lessons, this study focuses on outcomes and impacts of groups of mitigation projects, rather than detailed or immediate project outputs
The study draws on information gathered from a comprehensive portfolio review, greenhouse gas (GHG) emission data and development statistics, and two in-depth project cluster reviews within energy efficiency and renewable energy. The analysis was enhanced by several implementing agency reviews, other GEF monitoring and evaluation (M&E) reviews, and select country visits.
