In the introductory chapter, co-editor Andrew McLaughlin explains that a principal objective of the book is to inspire and guide aspiring and mid-career lawyers into the realm of sustainability by showcasing real-world examples of lawyers who have made significant impacts in this sphere. By offering insights into the triumphs and setbacks of these legal professionals, the book aims to make seemingly inaccessible career trajectories attainable, thereby encouraging a new generation of impact-focused lawyers. McLaughlin provides a personal narrative, detailing his entry into the sustainability space through lessons learned from a previous career in diplomacy, and in developing and implementing a global Environmental, Social, and Governance (ESG) Framework at his company.
