This book explores the evolving landscape of sustainable finance across various sectors and delves into critical topics ranging from the integration of Environmental, Social, and Governance (ESG) criteria in investment decisions to the transformative potential of blockchain technology. In more detail, three main perspectives are addressed: the issue of materiality and integrating ESG factors in the firm business model; the trends in the debt and credit markets; and the role of governance and transparency. In nine chapters, the book covers both a theoretical approach as well as empirical analysis, providing essential perspectives for regulators, investors, practitioners, and scholars navigating the complex landscape of sustainable finance.
