A number of insightful efforts have explored the nature of business–NGO partnerships and their associated outcomes for sustainable development. While some of these works have helped to clarify the benefits of such partnerships, and the different strategies NGOs can adopt in their interaction with business, others have identified the conditions necessary for a successful partnership. However, the question of how the different strategies adopted by NGOs in their engagement with business interact has remained relatively unexamined. Drawing on an environmental business–NGO partnership for sustainable development in Nigeria, this paper confirms the existence of a creative tension between the different NGOs’ strategies. This creative tension affects the nature of the environmental partnership and performs three main functions. These are an enabling function, a discipline function and a critical distance function. The article concludes by considering the theoretical and practical implications for business–NGO partnerships as a vehicle for sustainable development in developing countries.
