This book suggests an innovative approach to accounting that integrates the principles of the circular economy. The circular economy is a model of production and consumption, which involves sharing, leasing, reusing, repairing, refurbishing, and recycling existing materials and products as long as possible. In this context, a circular accounting book would aim to account not just for financial transactions in the traditional sense, but also for the environmental and social impacts of those transactions, reflecting a more holistic view of a business's operations and their effects on the economy and the environment.
