This study describes an ecological footprint analysis (EFA) project designed to help business students understand the significant environmental and social impacts of their lifestyles, and to encourage them to reduce these impacts over the course of the quarter through changes in consumption practices. Employing assessment methods developed specifically to measure the effectiveness of the project given its objectives, data were collected over a three year period from 225 undergraduate marketing majors enrolled in a 400-level sustainable marketing elective. Findings indicate that students willingly make significant reductions to their ecological footprint during the course and that most commit to continuing their reduction efforts over the long term. The results of this study demonstrate that an EFA exercise such as this, appropriate for use in any business course, makes students aware of the connection between business strategies and sustainable consumption and can effect significant changes in pro-environmental values and behavior over a short time period.
