'This inspiring book has been long overdue. It tackles an essential question for human survival in the 21st century: will we be able to transform our lives, businesses, buildings, settlements and the transport networks connecting them from unsustainable, oil-based and greenhouse gas emitting into sustainable, fossil fuel-free, zero-carbon metabolisms? This important volume and its two dozen contributors show that this path is necessary, practical and affordable. Read this book: its exciting, fresh insights will show you how to move from promise to practice.'
