This chapter discusses the ProSPER.Net initiative to integrate sustainability into business schools in the Asia-Pacific region. The project deserves scrutiny, as it led to positive change within each of the partner universities, involving innovative research, curricular transformation and the development of regional case studies. As such, the project is an instructive case in its own right, highlighting the successes, as well as the obstacles encountered, in introducing and coordinating education for sustainable development (ESD) in diverse organizations. The experience of the project clearly shows that whereas there is a recognized need to promote ESD in business schools throughout Asia, the process of achieving this is difficult and complex. Through a consideration of the achievements and frustrations of the project, it is hoped that this chapter will contribute to a better understanding of these issues, and will help in subsequent efforts to integrate sustainability in business education
