This case study is about how Greenpeace used social media to foster change in Nestlé SA (Nestlé). Experts felt that the environmental protection group made clever use of social media and direct action against the European food processing giant. The campaign proved to have high impact, forcing Nestlé to clarify its stance on palm oil and create a timetable for cleaning up its palm oil supply chain. This case is meant for MBA/ MS students as a part of their IT & Systems/ Organizational Behavior curriculum. It can also be used in Marketing Management curriculum.
