Included in Part 2 (The Purposeful Investment Landscape) under the Impact Investment chapter, the YouTube video “What is Impact Investing?” is cited because it concisely defines impact investing as deploying capital across asset classes with the explicit objective of achieving positive social and/or environmental outcomes alongside financial returns, situates impact investing on a spectrum with traditional, responsible and sustainable investing as well as philanthropy, and offers practical guidance—decide your priorities, set a strategy, learn from experienced peers and intermediaries, then start—thereby reinforcing the book’s theme of harnessing wealth with a why and urging action amid urgent environmental and social challenges.
