This Handbook assembles original contributions from influential authors such as Herman Daly, Paul Ekins, Marina Fischer-Kowalski, Jeroen van den Bergh, William E. Rees and Tim Jackson who have helped to define our understanding of growth and sustainability. The Handbook also presents new contributions on topics such as degrowth, the debt-based financial system, cultural change, energy return on investment, shorter working hours and employment, and innovation and technology. Explorations of these issues can deepen our understanding of whether growth is sustainable and, in turn, whether a move away from growth can be sustained. With issues such as climate change looming large, our understanding of growth and sustainability is critical. This Handbook offers a broad range of perspectives that can help the reader to decide: Growth? Sustainability? Both? Or neither?
