Through rich storytelling and exclusive insights from the world’s most influential CEOs and the next generation of leaders and startup pioneers, he details the steps we can all take to move towards our sustainability goals.”—ADENA T. FRIEDMAN, President and CEO of Nasdaq, Inc. “Based on in-depth research, Clarke offers a groundbreaking, inspiring and practical picture of what it takes to be a leader who does their part to build a better future. Full of concrete examples and stories, Sustainable Leadership is an indispensable book for this critical time.”—HUBERT JOLY, former Best Buy Chairman and CEO; Author of The Heart of Business; Senior Lecturer, Harvard Business School “Clarke shares a powerful lesson on why sustainable leadership is so important to corporations—and the world. This is an essential guide for any executive looking to kickstart their impact today and the next generation of leaders looking to accelerate sustainability action tomorrow.”—SANDA OJIAMBO, Assistant Secretary-General and CEO, United Nations Global Compact “Clarke draws on established firms and start-ups, rising star CSOs and visionary CEOs to offer a simple, but powerful set of competencies that will become a new ‘core curriculum’ for sustainable leaders across the world. An invaluable read for people across the career journey who aspire to make meaningful change.”—JASON JAY, Senior Lecturer and Director, MIT Sloan Sustainability Initiative “The characteristics of a successful sustainable leader exist within most executives; Clarke’s book is an invitation to seek them out. He spotlights leaders from across industries who are daring enough to harness those innate skills in the face of significant challenge and provides a toolkit for those looking to shape the next generation of purpose-driven business.”—JIM COULTER, Founding Partner and Executive Chairman, TPG; Co-Managing Partner, TPG’s The Rise Fund
