This book explores national and transnational companies' Corporate Social Responsibility (CSR) activities in times and settings in which they are confronted with economic and social challenges and analyzes these situations, ranging from the financial crisis to fourth generation sustainability. Presenting a number of different cases from various parts of Europe, North America and Africa, it showcases how companies respond to the challenges of the development, consultation, implementation, integration, measurement and consolidation of CSR. Further it specifies how these corporations deal with uncertainties over corporate and financial resources, global financial stability and growing evidence for climate change. The book describes CSR adaptation under challenging circumstances and argues for the strategic and operative legitimation of Corporate Social Responsibility in times of crisis.
