The changing relationship between business and the natural environment offers both challenges and opportunities for firms. In this course we will discuss many facets of business, including financing, risk management, measurement, competitive positioning, innovation, and strategy in the context of increasing pressures for improved environmental sustainability. The course will be interactive and discussion-oriented, with a case discussion in most class sessions, supplemented by debates, simulation exercises, visitors, student presentations, discussions of recent news articles, and mini-lectures. The course is appropriate for all students interested in how demands for sustainability will continue to change the business environment.
