This paper challenges the traditional understanding of environmental governance by arguing that spatial and scalar concepts are often taken for granted as fixed and natural. Instead, it proposes a new spatial grammar that considers both the politics of scale and the politics of networks. The author examines how environmental governance involves processes of scaling and rescaling, as well as the creation of new networked arenas of governance. The paper highlights the importance of recognizing hybrid forms of environmental governance and their political and ecological implications. The article discusses the role of transnational municipal networks (TMN) in environmental governance, using the Cities for Climate Protection program as an example. It argues that TMN challenge traditional accounts by engaging in both a politics of scale and the creation of new governance spheres. The paper also explores the limitations of current approaches to global environmental governance, which often treat space and scale as hierarchical and discrete. It suggests that a more nuanced understanding of scale and networked governance is necessary to grasp the complexity of environmental governance. The paper also critiques the traditional view of the state as the primary arena of political power, arguing that non-state actors play an increasingly important role in environmental governance. It discusses the emergence of global civil society and the need for a post-sovereign account of environmental governance that recognizes the role of multiple actors and institutions. The author emphasizes the importance of considering the politics of scale and the rescaling of the state in understanding environmental governance. The paper concludes that a new spatial grammar is necessary to account for the hybrid and networked nature of environmental governance.This paper challenges the traditional understanding of environmental governance by arguing that spatial and scalar concepts are often taken for granted as fixed and natural.
