Social enterprise and responsibility have been a prime area of focus for top business schools, and our clients at The MBA Exchange, for years now. MIT Sloan's commitment stands out even in this context, however. The following link is a great place to start exploring the school's offerings: (http://mitsloan.mit.edu/newsroom/indepth-social-solution.php)
As you continue to explore your options, you may want to review the offerings of Net Impact (https://netimpact.org/), a global community of students and professionals aligned with your interests. Until 2012, The Aspen Institute also published an MBA ranking, "Beyond Grey Pinstripes," (http://www.beyondgreypinstripes.org/), which specifically addressed schools' attention to social and environmental impact. Previous years' reports, as well as other Aspen Institute resources on the topic, may be other helpful sources in your research.
