Earth at Risk shows what a world organized along the principles of sustainability could look like, building on the experience of the 2015 Paris Climate Conference. Though formidable obstacles remain, Claude Henry and Laurence Tubiana present the case for collective initiatives and change that build momentum for implementation and action.

Claude Henry, a physicist turned economist, is a professor of sustainable development at Sciences Po Paris and at Columbia University. He is also currently president of the Scientific Council of the Institute of Sustainable Development and International Relations.

Laurence Tubiana is the founder and director of the Institute of Sustainable Development and International Relations and professor and director of the Sustainable Development Center at Sciences Po Paris. She was the special representative of the French Minister of Foreign Affairs for the 2015 Paris Climate Conference (COP-21) and French ambassador for climate negotiations.

Johan Rockström, Stockholm University:
A must-read for everyone concerned over humanity’s future on Earth. Henry and Tubiana are clear: a global transformation to sustainability is our only path to equity and prosperity. The situation is dire, but they provide overwhelming evidence that we have the solutions we need—we must now adopt them. A remarkable achievement, balancing risk and pragmatic hope in a perfect mix.

Scott Barrett, Columbia University:
In Earth at Risk, Claude Henry and Laurence Tubiana do more than explain why action is urgently needed to conserve the world’s natural capital. They also explain why some previous efforts failed, why others succeeded, and how, drawing from the lessons of both kinds of experience, the world can achieve sustainable development in the future.

Stephen Heintz, president, Rockefeller Brothers Fund:
Earth at Risk is uncomfortable but essential reading. Our planet and the life it sustains face imminent peril from humankind’s success. As the authors make abundantly clear, it is now up to humankind to redefine success, to reinvent economics, to develop a new global ethos of caring and sharing and, above all, to take with fierce urgency, the bold steps necessary to avert disaster.

Bill McKibben, author of The End of Nature:
The authors are ideally situated to understand the ins and outs of the climate crisis, and in this book they deliver an insightful overview, one that will be useful to any student of our dilemma.

John F. Kerry, former U.S. Secretary of State:
Claude Henry and Laurence Tubiana have written a critical book at a critical time. Earth at Risk is an in-depth, detailed account of the challenge our world faces, coupled with provocative suggestions of a path forward. Chapter after chapter provides essential context of the threats, grist for the debate over how to confront them, and required reading for policy-makers wrestling with reality.
