The convergence of a number of factors is driving an increase in investment and focus on sustainability. More specifically, high profile corporate scandals, recognition of the finite and increasingly costly resources on our planet, a shrinking globe with far more transparency and increasing consumer power are serving to elevate the imperative of sustainability. That said, there is wide variability in the definition of sustainability, the scope of efforts aimed at sustainability, and the perceived effectiveness of sustainability efforts. This is not surprising given the newness of the field and the attendant absence of theory, frameworks, and uniform measurements to deliver value attributable to these efforts. This class intends to introduce students to the opportunity and challenges facing startups and established companies as they contemplate the import of...and approach to creating a sustainable enterprise. Illustrations of progressive models (e.g. TOMS, GE, Marks & Spencer) will be coupled with case studies, lectures, practitioner speakers and debate to engage students in the nuances and intricacies of this developing field. This class will be taught from the perspective of practitioners and emphasize the real challenges of making operating decisions in an increasingly complex context.
