A new, weeklong intensive elective course at HBS (a Short Intensive Program, or SIP) brought approximately 80 students and more than 40 experts across industry and academia to discuss the policies, innovations, financing, opportunities, and complexities of climate change in the business context. Built collaboratively by the Business and Environment Initiative and the teaching team of HBS faculty Eleanor Laurans, Jim Matheson, and Peter Tufano, the course was a response to the groundswell of interest from MBA students.
