Towards a Unifying Framework of Impact Assessment in Impact Investing

This chapter advocates for a unifying framework for impact assessment in impact investing, addressing the current lack of common language and diverse methodologies. It proposes that the Global Impact Investing Network (GIIN)'s characterization of impact investing can serve as a basis for assessing impact along an impact value chain, distinguishing outputs from outcomes and impacts. Such a framework would facilitate comparisons, aggregation, and better managerial decision-making for social purpose organizations.
