This book aims to inspire a new generation of lawyers by showcasing real-life case studies of how legal professionals have built successful and rewarding careers in the field of sustainability. In the corporate world, over the last decade environmental, social and governance (ESG) and sustainability considerations have moved from the fringe to the mainstream - a shift that has faced significant backlash in certain quarters. At the same time, the global backdrop has become increasingly complex, marked by the accelerating impacts of climate change (e.g. historic floods and wildfires), political polarization, economic uncertainty, wars, and the further erosion of trust in our institutions. In this new era, corporate leadership is increasingly turning to lawyers, both in-house and external counsel, to help lead the way in navigating these complexities and to pursue opportunities through the green energy transition. This book brings together a diverse group of leading lawyers who have spearheaded innovative initiatives to drive positive environmental and social change. These thought leaders share their firsthand experiences, challenges, and triumphs, providing inspiration for aspiring lawyers eager to make a meaningful impact in their careers.
