Climate change is increasingly recognised as the greatest threat to human and ecological sustainability in the 21st Century. Governments, businesses, non-government organisations and concerned individuals are urgently seeking the right set of responses to avoid dangerous climate change. Most of the proposed solutions focus on systemic changes in technology, markets and institutions. Very few proposals grapple with the critical task of understanding how individual values and shared worldviews contribute to climate change. This book uses an emerging framework called Integral Theory to structure a comprehensive analysis of the exterior and interior dimensions of climate change. Using a case study on Australian energy and greenhouse policy, the book introduces Integral Theory and tests its value as a tool for understanding the hidden dimenions of our sustainability challenges and identifying new ways to respond. The book will be of great interest to those that are seeking to apply Integral Theory, particularly in the area of sustainability. It will also be of interest to anyone concerned with sustainability or climate change and seeking a foundation for a broader response.
