Sustainability Communicationsoffers a timely and practical examination of how sustainability is being communicated across corporate, NGO, and government sectors. As sustainability becomes a core component of global business strategy-tied not only to reputation, but also to regulation-the role of communications and PR professionals is rapidly evolving. This book provides a comprehensive overview of how communicators can navigate the complex and often high-stakes environment of sustainability communications in a way that is transparent, ethical, and aligned with stakeholder expectations. Bridging theory and practice, this book offers models, tools, and real-world guidance for professionals managing sustainability narratives. It addresses the challenges posed by new terminologies, fast-changing legislation, and rising public scrutiny. Drawing on global perspectives, this book features contributions from practitioners with on-the-ground experience, ensuring a diverse and internationally relevant framework. It also explores how communicators must adapt in the age of the chief sustainability officer, where credibility and consistency in messaging are essential to organisational integrity.
