This book explores the psychological impact of climate change on organisations and individuals, encouraging the reader to consider the ways in which they can take action to address this critical issue. Written in a clear and concise style, with an emphasis on the application of theory to practice, the author takes topic areas from work psychology to help readers identify methods which are appropriate to them personally and for their organisations. Topics such as the management of change, leadership, engagement, and wellbeing at work are of interest to many professionals in the workplace. The climate crisis makes it even more important that these issues are addressed in a systematic, robust, and effective manner. This is a handbook of the psychological principles underpinning the actions required to support, encourage, and enable individuals, managers, and leaders to implement the range of actions required in their organisations and practice. This is a valuable resource for students, academics, and practitioners of occupational psychology, environmental psychology, and sustainable business. It will also be of interest to a variety of other practitioners and researchers interested in climate mitigation, as well as businesses and HR professionals looking to use occupational psychology in their climate strategies, and those working in ‘green’ jobs.
