Case Studies

As the evolution of the impact investing industry moves from "what is it" to "how is it done", case studies become increasingly important.

What does impact investing look like in action?

According to the GIIN's most recent Annual Impact Investor Survey, there isn't one single way to be an impact investor. 

With so many different types of investors pursuing a variety of impact objectives and financial return targets, the GIIN aims to bring greater transparency to the market by sharing diverse examples of impact investments and viewpoints held by investors who are motivated by social and environmental considerations.*
