As we increase our awareness of the planetary challenges and how they intersect with the discipline or profession we choose to focus on, we have put our attention on the external forces and impacts. What remains untouched however is the set of beliefs, values, assumptions, mental processes, and paradigms that we hold and share: our mindset. But how do we change a mindset? This book is the first to introduce the 12 Principles for a Sustainability Mindset, presenting educators with a framework that makes it easy to include them into teaching plans and lessons of any discipline. Written in a very clear and practical way, the book provides examples, checklists, tips, and tools for professionals and educators. It transforms the development of a much-needed mindset for sustainability into an accessible, fun and intuitive task. The book is written with educators from a variety of disciplines in mind, including but not limited to management educators, coaches, and trainers. No other book comes close to providing such a well-organized and solid way of starting to shift our mindsets in the direction of sustainability.
