Mending the ozone layer: The role of transnational policy networks

Successful international cooperation is a puzzling problem for social scientists. The ozone layer has been subject to both international treaties and domestic leg-islation. It is one of the foremost success stories in international relations, yet insufficiently understood. In this paper I argue that existing approaches - including the sophisticated and highly acclaimed epistemic community approach - do not take the underlying theoretical problems seriously enough. Departing from the epistemic community approach, I propose a framework for a network analysis combining interests, knowledge and power into a coherent model, which is derived from this case but can apply to similar cases sharing similar characteristics. It is argued that one of two rivaling policy networks gained hegemony over the other, mainly by winning over allies from the competing network. Ultimately this contributed to the competing network's breakdown.
