"The US SIF Annual Conference offers a unique opportunity to network with leaders of sustainable, responsible, and impact investing, to hear from leading investors, CEOs and policymakers, and to learn about new approaches, trends and policy developments in the field. " 

Taking place in Chicago this year, the US SIF Conference's primary theme will be exploring the role of impact investing in a changing political environment that is coupled with a growing mainstream acceptance for impact investment in the broader financial sector.
