In some cases, there can be a failure to demonstrate ‘financial additionality’ i.e. that the private finance mobilised would not have occurred without the public intervention (CAFOD/Oxfam/ActionAid UK/Eurodad/WWF/BOND, 2015). In regard to climate finance, Nakhooda and Norman (2014) attribute part of the lack of evidence to the absence of a clear, consistent approach for measuring the impact of climate finance more broadly, and private sector engagement for climate change, in particular. The lack of consistent monitoring is compounded by issues related to attribution of impact and to the establishment of baselines for the analysis. In the case of adaptation, for example, it would be valuable to know to what extent the private sector needs to be supported in its risk management in order to provide economic stability.
