Regional environmental governance has emerged as a viable alternative to supranational environmental solutions, using regional and local knowledge and actors to tailor more effective policies. This does not deny a role for supranational institutions, however, which can enable their members to effectively shift towards such a decentralized and polycentric approach. In specific regions such as the Arctic, with many national and local actors interested in environmental improvement, such impetus from meta-organizations (i.e., organizations comprised of organizations) could result in beneficial environmental outcomes. This paper examines an underutilized institution, the Eurasian Union (EaEU), and the role it currently plays in facilitating regional environmental governance. Focusing on its largest member, Russia—and the only member with an Arctic linkage—I explore the tension between supranational facilitation and interference in an area not directly affecting all members. Despite explicit Russian interest in this realm, the EaEU may be able to influence Russian environmental policy for the better via multilateral means and internal mechanisms. By challenging the Russian monopoly on Arctic policy in the EaEU, these additional voices may create space for environmental innovation in areas not central to Russia’s interests.
