About Us The Global Impact Investing Network (GIIN) is a nonprofit organization dedicated to increasing the effectiveness of impact investing.

The Global Impact Investing Network is a 501(c)3 nonprofit organization dedicated to increasing the scale and effectiveness of impact investing. Impact investments are investments made into companies, organizations, and funds with the intention to generate measurable social and environmental impact alongside a financial return. They can be made in both emerging and developed markets, and target a range of returns from below market to market rate, depending upon the circumstances. The GIIN addresses systemic barriers to effective impact investing by building critical infrastructure and developing activities, education, and research that attract more investment capital to poverty alleviation and environmental solutions.

The GIIN is currently a sponsored project of Rockefeller Philanthropy Advisors.

GIIN Initiatives

The GIIN has five key initiatives:


The GIIN's Outreach initiative elevates the profile of the impact investing industry by highlighting examples of impact investments, tracking industry progress, and sharing market information and best practices with the diverse impact investor community, potential impact investors, and the general public. The GIIN attends and speaks at industry events, informs conference and event programming, and promotes mainstream traditional and social media coverage of the impact investing industry. In addition, the GIIN's practitioner-focused research draws on its industry networks and leverages data gathered through its programs.

As part of Outreach, the GIIN maintains an online impact investing resource center, which features research, news clippings, events, useful links, and GIIN publications about impact investing. The GIIN also hosts an online Career Center, which is a free source for top job openings in impact investing from members of the GIIN and other impact investing organizations. Additionally, the GIIN authors and circulates a free monthly newsletter that features the latest impact investing news and events, as well as Investor Spotlight interviews with leading impact investors about their motivations, strategies, and deals.

Impact Reporting and Investment Standards (IRIS) is a set of metrics that can be used to describe an organization's social, environmental, and financial performance. IRIS is designed to address a major barrier to the growth of the impact investing industry - the lack of transparency, credibility, and consistency in how organizations and investors define, measure, and track their performance. The IRIS initiative has three main components: (1) developing and refining IRIS; (2) increasing accessibility of IRIS promoting IRIS use; and (3) encouraging voluntary contribution of self-reported, anonymous IRIS performance data to provide additional market intelligence.

By using IRIS to track social, environmental, and financial performance, a wide range of investors and organizations can communicate their social, environmental, and financial performance using the same terms and definitions. This consistency helps investors evaluate and compare performance for more accurate assessment and comparison, and helps portfolio organizations track and improve their business and social performance.

Investors' Council

The GIIN Investors' Council is an exclusive leadership group for active large-scale impact investors. Comprised of asset owners and asset managers with diverse interests across sectors and geographies, the Investors' Council provides a forum for experienced impact investors to strengthen the practice of impact investing and accelerate learning about new areas in the field. As leaders, Investors' Council members also participate in field-building activities such as infrastructure development and research to advance the broader impact investing industry.

The Investors' Council currently supports two working groups focused on specific impact investing themes. The first working group, Terragua, is composed of Investors' Council members that are focused on increasing investment in sustainable agriculture in sub-Saharan Africa, with a goal to improve the lives of poor farmers and their families. The Inclusive Finance Working Group is composed of Investors' Council members interested in inclusive finance, particularly financing access for small and medium enterprises, microfinance, and financial inclusion access platforms.
