IRIS+ makes it easier for investors to translate their impact intentions into impact results.

All investors and companies create positive and negative effects on society and the environment. Impact investors seek to maximize the positive and minimize the negative by using the IRIS+ system to integrate social and environmental factors into investment decisions alongside risk and return.

Credible, comparable impact data are needed to inform impact investment decisions and drive greater impact results. IRIS+ solves for this by increasing data clarity and comparability, and it provides streamlined, practical, how-to guidance that impact investors need, all in one easy-to-navigate system. It is a free, publicly available resource that is managed by the Global Impact Investing Network – the global champion of impact investing.
