Variations of a Social Finance Theme: Socially Responsible Investing, ESG, Sustainable Investing, and Impact Investing

In recent years, sustainable investment has gained considerable traction among private and institutional investors, leading strategies such as socially responsible investing (SRI), environmental, social, and governance (ESG) investing, and impact investing to become mainstream. This chapter examines the evolution of these investment approaches, highlighting their distinct methodologies, the challenges they face, and the opportunities they provide for driving positive societal and environmental change. Although sustainable investing is not without its challenges—including subjective criteria, varying standards, and issues with measurement—its growth reflects an increasing commitment among investors to align their financial objectives with their values. Sustainable investment offers a powerful framework for making meaningful and lasting contributions to corporate behavior and global sustainability while pursuing financial returns.
