Environmental and social (E&S) sustainability is an explicit strategic pillar of many multilateral development banks (MDBs) investing in private sector. The projects encompass a wide range of E&S risks and opportunities; pollution control and waste management, occupational health and safety, protection of biodiversity, global aspects -especially climate change-, and social aspects including community engagement, land acquisition, involuntary resettlement, indigenous people and cultural heritage, which clients should manage with their social and environmental management systems. This presentation analyzes the challenges encountered in evaluating E&S performance and impacts in various industry sectors and methodology to identify and benchmark performance indicators. #MultilateralDevelopmentBanks #EnvironmentalPerformanceEvaluation #ProjectEvaluation #2011Conference #EnvironmentalProgramEvaluation
