This book concerns a unique approach of assessing the high increasing rates of adherence to ESG principles in 2025 through the perspective of an interdisciplinary, corporate governance approach. As regulatory authorities and related authorities globally demand adherence and a genuine adoption of a standardised understanding and implementation of ESG principles, new methods of assessment are being agreed. Despite its importance, ESG has not been successfully analysed within this context. It could serve as a unique textbook to lecturers as well as a general book for specialists and practitioners in the fields such as law, economics, management and governance. As large companies are in particular need to comply with ESG adoption, this book assesses the history of its roots in the City of London and its development through Lord Melvyn King and the King Laws in South Africa.
