Saddle BagsOver the past 25 years, most major business schools in the world have added some kind of initiative, center, or program focused on sustainability, corporate citizenship, or social entrepreneurship. The problem is that virtually all of these initiatives, centers, or programs tend to hang off the side of the existing business school edifice. Like the proverbial "saddle bag" on a horse, the issues are contained within separate compartments that are readily visible from the outside, but have little impact on the behavior of the animal itself. Sustainability has joined other business school "saddle bag" issues such as ethics, entrepreneurship, and emerging economies, as a way to recognize, but stop short of fully integrating them into the core DNA of the institutions.

It is high time to move beyond saddle bag sustainability in business education. The social and environmental challenges we face call for nothing less. That is why the SEMBA curriculum is so unique and important: It seeks to fundamentally reinvent business education and the MBA degree to address the challenges we face in the 21st century-environment, ethics, entrepreneurship, poverty, and inequality. With SEMBA, we have taken off the saddle bags and designed a new horse. The curriculum is new and focused 100% on sustainable entrepreneurship.
