Environmental Management Accounting (EMA) is increasingly recognised as a distinguished tool of environmental management. It helps to integrate a company's environmental and business interests, whereby enhancing corporate eco-efficiency in terms of reducing environmental costs or making one's product more competitive. This book gives a comprehensive coverage of the state of the art. It presents a number of EMA frameworks that companies can take as a basis for implementing their own specific EMA structures. Besides discussing environmental accounting issues within conventional management accounting, it gives a detailed picture of materials flow (cost) accounting as an alternative way of looking at the ecology-economy relationships at the corporate level. A fascinating case study shows how a large company (Siemens) applies materials flow accounting and what benefits it entails.
