Prosperity Without Growth is a book by author and economist Tim Jackson. It was originally released as a report by the Sustainable Development Commission. The study rapidly became the most downloaded report in the Commission's nine-year history when it was published in 2009. The report was later that year reworked and published as a book by Earthscan. A revised and expanded edition (Prosperity Without Growth: Foundations for the Economy of Tomorrow) was published in January 2017.
