Environmental, Social, and Governance (ESG) investing has surged into a $50 trillion market, reshaping global finance—but is it truly driving sustainable change or just another overhyped trend? This book takes a deep dive into ESG investing, cutting through the noise to distinguish real impact from marketing gimmicks. It explores how ESG ratings work—and why they often fail to measure genuine sustainability, the greenwashing problem where companies mislead investors with false claims, and the real winners and losers—who is driving meaningful change versus who is merely capitalizing on the trend. It also examines how AI, big data, and evolving regulations will redefine ESG investing and provides practical strategies to identify authentic ESG opportunities while avoiding greenwashing traps. Featuring in-depth case studies, expert insights, and actionable guidance, this book is a must-read for investors, finance professionals, and anyone seeking to make informed, sustainable investment decisions in an increasingly complex landscape.
