"The impact measurement guidelines were developed by a Working Group on Impact Measurement, launched as part of the G8 Social Investment Taskforce at the G8 Summit in London, 2013. The guidelines outline impact measurement best practices for impact investors and the "impact organizations" (i.e., investees) they work with. The Guidelines for Good Impact Practice were developed to be practical in nature, broadly applicable, adaptable to the unique goals and internal/external context in which an investor operates, and - importantly - designed to be applicable at a portfolio, deal, and enterprise level. This work builds significantly on the work of the EVPA and aligns with recently adopted European Standard for Social Impact."
