Impact measurement is central to effective impact investing, as it demonstrates investor intent and legitimizes the industry with data on impact produced. Good impact measurement generates intrinsic value for all impact investment stakeholders, yields data to mobilize greater capital toward generating impact, and increases the transparency and accountability for the impact delivered.
Measuring Impact, the Guidelines for Good Impact Practice, and the associated case studies were developed by the Impact Measurement Working Group (IMWG) of the Social Impact Investment Taskforce established under the UK’s presidency of the G8. The combined work elevates existing best practices and aligns with the European Standard for Social Impact Measurement (developed by GECES). The IMWG was established in June 2013 at the G8 Social Impact Investment Forum in London to develop measurement guidelines for impact investors, as well as a vision for impact measurement in the years ahead. The IMWG is comprised of 29 though leaders in impact investing and measurement—including private investors, foundations, academics, nonprofits, and intermediaries—representing diverse sectors and geographies. It was co-chaired by the GIIN and New Philanthropy Capital (NPC).
The full Measuring Impact report and the accompanying case studies were launched in September 2014.
