This paper studies how collective action led by multinational corporations (MNCs) tackle plastic pollution in emerging countries. While literature has identified challenges met by corporations involved in the management of environmental problems, devices of collective action such as meta-organizations are increasingly used by organizations. Against this backdrop, we rely on the concept of meta-organizations, meaning organization of organizations, to understand how leading MNCs leverage collective action to support waste management infrastructure for plastic waste. Drawing on a qualitative study of five cases of metaorganizations (MOs) in West Africa and South-East Asia, we situate our findings at three different levels. At the organizational level, we describe that subsidiaries of MNCs develop meta-organizations focusing on the issue of plastic pollution, combining political and corporate social responsibility (CSR) activities. At the inter-organizational level, these MOs are used by MNCs to push a specific type of mandatory regulation that we qualify as "hybrid". To get this regulation successfully adopted and implemented by national governments, MOs are highly dependent on the national context, multi-stakeholder deliberation being highly influenced by the deliberative strategy adopted by governments. By identifying multi-level mechanisms, we highlight how and why meta-organizations led by corporations adopt political and/or CSR activities and develops different degrees of partialness.
