Book excerpt: This book provides a detailed overview of ecological money and finance. The functioning and development of the monetary and financial systems are analysed in relation to sustainability constraints to highlight the actions required to meet the 2030 Sustainable Development Agenda. Empirical case studies are utilized to give insight into the failure of the traditional financial system, with ways in which they can be overcome also considered. This book adopts a pluralist perspective to revisit the foundations of financial and monetary economics from a sustainability perspective, and examines the economic and financial instruments that can be used to combat ecological challenges. It will be relevant to students and researchers interested in ecological economics and sustainable finance.
