Book excerpt: A climate catastrophe can be avoided, but only with a rapid and sustained investment in companies and projects that reduce greenhouse gas emissions. To the surprise of many, this has already begun. Investors are abandoning fossil-fuel companies and other polluting industries and financing businesses offering climate solutions. Rising risks, evolving social norms, government policies, and technological innovation are all accelerating this movement of capital. Bruce Usher offers an indispensable guide to the risks and opportunities for investors as the world faces climate change. He explores the role that investment plays in reducing emissions to net zero by 2050, detailing how to finance the winners and avoid the losers in a transforming global economy. Usher argues that careful examination of climate solutions will offer investors a new and necessary lens on the future for their own financial benefit and for the greater good. Companies that reduce greenhouse gas emissions will create great wealth, and, more importantly, they will provide a lifeline for humanity. Grounded in academic and industry research, Usher’s insights bring clarity to a complex and controversial topic while illuminating the people behind the numbers. This book sets out a practical and actionable plan for investors that will alter the course of climate change.
