After nearly two decades of tergiversation, E. I. du Pont de Nemours and Company announced in March 1988 that the production of chlorofluorocarbons (CFCs) would be phased out.

This case is about the decision-making process that led André and Rosalie Hoffmann to establish InTent, a non-governmental organization that forges action-based partnerships that fight for sustainable solutions for business, people and planet.
