Averting Climate Catastrophe Together addresses the necessity of meeting the Paris Agreement temperature target and explores what framework could enable climate action in an effective, efficient and equitable manner that is consistent with that goal. It also looks at the contribution of technological change within the economic system, including the feasibility of a global energy transition. Whether humanity can avoid catastrophic climate change does not seem to depend on the availability of technological solutions, but rather on international cooperation and coordination. Given the various sustainability issues, this book also considers if it is possible to derive a general approach to them. It argues that dealing with compatibility limits in complex systems requires a holistic change in the system structure. Therefore, systems science is discussed together with economics, technological change, and sustainable development
