As the impact investing industry evolves, so does its need for a “common language” for understanding and describing impact. The Global Impact Investing Network (GIIN) has been managing IRIS—a catalog of generally accepted performance metrics used by leading impact investors to measure social, environmental, and financial performance—since 2009. The GIIN remains dedicated to developing IRIS together with the impact investing industry, and is now working toward a significant upgrade to the catalog. Would you help the GIIN understand how IRIS can better meet your impact measurement and management needs? Send the GIIN your thoughts!
