This paper proposes a methodology for an interdisciplinary, empirical enquiry into the diffusion of the legal concept of ‘benefit-sharing’. The paper draws together accounts of norm diffusion from sociology, international relations and law to devise a theoretical approach for the empirical research of global environmental law. Against this background, the paper explores the usefulness of process-tracing, the relevance of frames and the need for a participatory action research approach for a research project focused on benefit-sharing as a tool to operationalize equity among and within States
