Corporate citizenship protagonists -- whether academics or practitioners -- are increasingly being challenged with regard to the relevance of corporate citizenship as a driver for global change. This special edition of the Journal of Corporate Citizenship directly addresses this challenge, focused on the theme 'Is corporate citizenship making a difference'?All but one of the articles in this special edition were chosen from the Unisa Centre for Corporate Citizenship 2nd international symposium, co-sponsored by the University of Washington's Lindenberg Center and the UN Global Compact, which had as its theme the same question. This issue is edited by Ralph Hamann, Environmental Evaluation Unit, University of Cape Town/Unisa Centre for Corporate Citizenship, South Africa, Sanjeev Khagram, Professor of Public and International Affairs and Director of the University of Washington's Lindenberg Center, and Maggie Opondo , University of Nairobi, Kenya.
