This book marks a milestone in Economics publishing. Sustainable Economics is *the* subject of the moment, as businesses across the globe face up to peak oil prices, climate instability, increasingly complex environmental legislation and the challenge of adapting to a new business landscape. Sustainable Economics: Context, Challenges and Opportunities for the 21st Century Practitioner debugs the language of sustainable development. It explores the strengths and weaknesses of the many and diverse schools of thought. The book enables the modern business student and practitioner to disentangle the complex, often convoluted debate relating to sustainability, and it provides the tools necessary to lead their organizations through the murky waters of current times and prepare for the challenges of the future. Eschewing the linear - take, make and waste - approach of current business and manufacturing thinking, this book revisits the ecological models underpinning recent economic sustainability theory, and re-examines the consequences of modern ecological thought upon business strategies relating to sustainability. A chapter is also dedicated to the "circular economy", already in common parlance at policy levels in the UK, and notably in China and other developing countries. Packed with the most recent research papers, Sustainable Economics is an essential resource for the 21st-century business practitioner and legislator. The book is supported with a large array of teaching and learning material, for both formal and informal use, ranging from role play to data analysis which are available on request with the purchase of this book.
