The IPR for the Mongolia was carried out between April and October 2019 by Impact Evaluation Unit staff, including an in-country mission during 2-6 September 2019. The approach broadly followed the approach set out in the IPR Guidelines, and involved: (1) a review of program documentation (Annex 2), (2) interviews with internal and external stakeholders (Annex 3), and (3) a half-day workshop with GGGI Mongolia team to discuss the IPR findings and recommendations. The scope of IPR covered 14 core and earmarked-funded projects between 2015-2019 in the areas of energy, green cities and green financing, which shared common impact pathways (Annex 1). The core of the IPR methodology involves developing a country program-wide impact pathway diagram, based on the logframes of all projects under the country program. The diagram for the Mongolia Program is shown in the report.
