Sustainability is of course vogue as well as being intentionally resource-conserving; yet despite its popularity and interest from the academic community, many of its characteristics still remain elusive. Its interpretation, management and cost seem only partially understood, for example, how can sustainability effectiveness best be measured? How do the opportunities for sustainability vary across different industry contexts? As such our interests lie in trying to better understand how opportunities for sustainability, particularly along a supply network, might manifest, and be performance- and cost-evaluated. Within this ebook a range of strong publications have been selected to help address some of these issues.
