This book offers a rigorous comparative analysis of corporate social responsibility (CSR) and corporate sustainability across seven jurisdictions, examining how law, governance institutions, and cultural traditions translate ethical commitments into enforceable corporate obligations. Beginning with India’s pioneering statutory CSR regime under the Companies Act 2013, the book moves through the Nordic countries of Norway, Sweden, Denmark, Finland, and Iceland, before concluding with Singapore’s calibrated market-based disclosure architecture. Each jurisdiction is examined through a consistent analytical framework covering cultural and historical context, regulatory design, corporate-level practices, and distilled best practices exportable to other markets. The book demonstrates that there is no singular pathway to embedding corporate responsibility. Mandatory redistribution, culturally embedded stewardship, and market-driven disclosure each offer partial answers, and the most durable advances occur where legal architecture, institutional enforcement, and social norms reinforce one another. This book is an essential resource for academics, researchers, and students in corporate governance, business ethics, sustainability management, corporate law, and international business. It is equally valuable for business leaders, managers, and CSR professionals, particularly those engaging with India, the Nordic countries, and Singapore.
