...this time around success will need to be measured not by how much we can control nature but by how well we can live as part of it. Our efforts in the transition to a sustainable future require decisions that not only acknowledge the ecosphere, but embrace the complexity of our societies and the natural systems that support us. A vital part of this transition is communication. We need to map and communicate as clearly as possible the impacts of our current trajectory and provide a clear and comprehensive system for tracking the world's progress towards sustainability... This book provides an introduction to input-output analysis for sustainability practitioners. It is designed for those with knowledge about the sustainability dilemma we face, but who are unsure about the how of measuring our impacts, tracking our progress and informing the decisions for a sustainable future. Input-output analysis placed in a transdisciplinary setting is a method that captures the complexities and interdependencies of our social, economic and environmental support systems. Examples of the use of input-output analysis in life-cycle assessment, triple bottom line accounting and carbon and ecological footprints are provided along with an introduction to a range of software tools. In academic circles research has been gathering pace on these methods and issues over the last years. This book brings this state of the art to the decision makers and policy shapers of today.
