This book compiles and explains technical terms in sustainable finance in an easy-to-navigate A-Z format. The interdisciplinary nature of sustainable finance means that those researching and working in the field often have to turn to a variety of different sources to look up various non-financial terms. Recognizing this issue, Ibrahim Sancak and Elisa Aracil have curated a comprehensive list of the key terms most commonly used in the field. Each entry maps out an important concept or idea and illustrates how it relates more broadly across this growing discipline, such as the changes and innovations required by the financial sector to meet the United Nation's Sustainable Development Goals. Overall, Essential Concepts of Sustainable Finance will enable readers to communicate more effectively about finance within the context of sustainability. With related terms and further reading included alongside the entries, this innovative and accessible volume will be of great interest to students, scholars, and practitioners alike.
