Impact investing can be a powerful instrument of change. --Judith Rodin, President, The Rockefeller Foundation, and Margot Brandenburg, in the introduction A new wave of investors is using impact investing to address some of the greatest challenges of our time--from climate change and water scarcity to lack of access to health care, education, and affordable housing--with the intention of also generating a financial return. This couldn't happen at a more critical time. While philanthropy continues to be a transformative force for good, global philanthropic funds, even when combined with the development or aid budgets of many national governments, add up to mere billions of dollars. Meanwhile, the cost of solving the world's problems runs into the trillions. In The Power of Impact Investing, Rockefeller Foundation president Judith Rodin and Margot Brandenburg, two of the foremost experts in the field, explain what impact investing is, how it compares to philanthropy and traditional investments, where opportunities are evolving around the world, and how to get started. By sharing moving stories of impact investors and the exciting social enterprises benefiting from these investments, Rodin and Brandenburg offer a compelling resource for anyone interested in better understanding the power of impact investing--including retail investors, high-net-worth individuals, and heads of family offices, foundations, banks, and pension funds--while also offering experienced impact investors an opportunity to deepen their knowledge and benefit from the perspectives of other investors.
