Sustainability is becoming a business megatrend. This book looks into why controlling departments are rarely involved in sustainability topics and do not contribute to corporate responsibility. The author postulates the following assertion: responsible controlling is indispensable in making an organization more responsible. Inside, you'll learn a specific course of action for the development of a responsible controlling framework toward decision making, which is based on an ethically driven, reflective fundament in order to make a company a responsible business. Through the development of a responsible controlling framework, the author gives recommendations for how controlling should be altered in terms of both tools and mindsets. A twelve-step responsible controlling roadmap is detailed, showing how controlling can contribute to foster a corporation's responsible behavior and how sustainability topics can be integrated in management decisions. The conclusion of Responsible Management Accounting and Controlling reiterates the main goal of this book: responsible controlling must first and foremost be understood as a mindset. Responsible controlling, therefore, is an uncommon but indispensable approach of making an organization more responsible.
