This book provides a broad overview of how sustainability reporting has grown, how it is used now and where it is heading. Daily, we read and hear in various media about concepts such as corporate social responsibility (CSR), sustainability reporting, sustainability accounting, environmental reports, corporate citizenship or environmental management systems. Accounting for Sustainability decodes this terminology by providing an accessible introduction to the topic that explores sustainability reporting from an internal and external perspective. It begins with an overview of how sustainability reporting has emerged and why it is important, before moving on to cover definitions of key terms and specific theories and frameworks. Subsequent chapters explore the role of financial management, sustainability standards, accounting communication and capital markets. With learning outcomes and study questions embedded in each chapter, this book will be of great interest to students of sustainability reporting and accounting, as well as practitioners taking related professional accreditations.
