IRIS is managed by the Global Impact Investing Network (GIIN), a nonprofit organization dedicated to increasing the scale and effectiveness of impact investing. The GIIN offers IRIS as a free public good to support transparency, credibility, and accountability in impact measurement practices across the impact investing industry. IRIS provides added value in the following ways:

1 One-stop Shop

By cataloging the most useful metrics from across the industry in one place, IRIS takes the guesswork out of which performance metrics to use.


2 Aggregate & Compare

By providing a standard common language to talk about results, IRIS makes it easier to compare investments and aggregate information across a portfolio.


3 Increase Credibility

98% of investors recognize the importance of standardized metrics and over 5,000 organizations are using IRIS to evaluate, communicate and manage their social and environmental performance.

4 Reduce Reporting Burden

IRIS doesn’t reinvent the wheel and incorporates and aligns with widely accepted 3rd party standards wherever possible. Organizations can use IRIS as the anchor for their diverse reporting requirements.
