The Refugee Lens Investing Impact Measurement Tool is intended to help investors and companies measure the refugee-specific social impact of a refugee lens investment. Drawing on the GIIN’s IRIS+ metrics, the tool serves as a guide and walks the user through several key steps to determine what type of impact the investment will have, who is affected, the degree of change that will result, the contribution of this investment to the total measurable change, and the impact risk associated with the investment.
