Investors use IRIS+ to measure and manage the impact of an investment or a portfolio of
investments in a consistent way. Use of IRIS+ data in investment management processes allows
investors to account for the positive and negative effects of their investments and in doing
minimize negative effects and optimize positive effects. Investors use IRIS+ to generate
for use within at any stage in this process, from screening deals, to underwriting, to
conducting due diligence, and assessing performance. IRIS+ data can also be used to compare
performance between similar investment strategies, within similar Impact Categories and Themes or Sustainable Development Goals (SDGs).
