A decent introduction to the topic of sustainability for designers, with a focus on physical products. The book provides an overview of different sustainability models, frameworks, and design processes. However, it could probably do with some additional editing; most chapters are just long lists of items and read like a report. A revised version of the book titled Design is the Solution is available on the author's website (https://nathan.com/design-is-the-solu...), so consider buying that version instead if you're interested in this book.
