The CRSP ISS ESG Indexes are a unique, proprietary suite of “paired” indexes employing ESG performance ratings from Institutional Shareholder Services (ISS) to separate the CRSP Large Cap Index universe into “Qualifying” (ESG) and “non-Qualifying” (Remainder) index pairs. Each index pair provides investors with a transparent, distinct and representative partition of the entire US Large Cap equity market by the ESG rating of each underlying company.
