Quacquarelli Symonds Limited and The Aspen Institute produce a twice yearly Green MBA Rankings of programs based on social and environmental factors. There are only two Australian schools in the top one hundred: twenty third (Griffith Business School, Griffith University) and at seventy eight (University of South Australia IGSB). Of the current top 100, 31 are outside the USA. The top school is Canadian (York University, Schulich School of Business), the seventh is Dutch (Rotterdam School of Management, Erasmus University), the ninth is Spanish (IE Business School), twenty third UK (Nottingham University Business School).
Only business schools offering in-person full-time courses are ranked. This is a severe limitation in the methodology, as green business schools are likely to emphasise online, part time courses, due to their environmental benefits. However, the rules would appear to allow courses with an online component. As an example, ANU MBA students can undertake the ANU Green Information Technology course. This is an online unit, but undertaken by many enrolled full time on-campus students, who value the flexibility of the format.
