Sustainable thinking and sustainable business practices have come a long way in the past 20 years. But there's still a ton of room for improvement. Sustainability should be a core part of all business school programs.

Some leading European professors and students have triggered a strong push for wider and deeper incorporation of sustainability into business schools in Europe. And one of the three leading business school associations in the world, Europe's http://www.efmd.org/">EFMD, is pushing business school deans and executives to bring this into their programs more.

But, for a much larger impact, the other two leading business school associations, the Association to Advance Collegiate Schools of Business (AACSB) and the Association of MBAs, could do the same. Ask these associations to follow EFMD's lead by signing the petition below today.
