If you want to dive into the topic of sustainability, this is a great book to start with. The first 500 pages outline comprehensively what the sustainability concept is about, what the key elements are, what challenges you may encounter, and what you are able to achieve by successfully integrating a sustainable concept.
I deem chapters 12-15 especially interesting and helpful for practitioners. Here Blackburn provides practical advice on how to implement sustainable ideas in NGOs, governmental institutions, universities, and small businesses. Although Blackburn could have gone a bit more into detail on approaches for SMEs and other businesses, these chapters offer great opportunities for public institutions. Despite the fact that this book is relatively pricy (I bought a used paperback version and I considered it still expensive) it delivers a lot of extra content you will not find in other books. The 200 extra pages in the appendices provide handy tools and codes which are ready for use and implementation. Although I think that a few of these tools are too specific for a broad audience, the parts about the sustainability management system standards and cost cutting tips are definitely worth reading and valuable for almost everyone involved in implementing sustainability measures.
