This book engages with the implications of an expanding Corporate Social Responsibility (CSR) of Transnational Corporations in their supply chains. Taking the case of a cocoa sustainability certification project in Ghana, the study examines the implementation process of such a transnational CSR intervention and its outcomes regarding the local governance and institutional environment of the cocoa sector in Ghana. The study deploys a theoretical framework based on Global Value Chain Analysis and a neo-Gramscian approach to Global Governance to assess transnational CSR as a concept and strategy that reflect power struggles in global production fields.
