Alongside the climate change denial movement, a section of the capitalist class has been organizing to promote a project of "climate capitalism" that relies on carbon markets and other policies compatible with the neoliberal order to reduce greenhouse gas emissions. Like the denial movement, promoters of climate capitalism have constructed an extensive network of think tanks and policy-planning groups to foster adherence to their climate policy proposals. This article uses social network analysis to map out the reach of these climate and environmental policy groups within the array of interconnected NGOs, inter-governmental organizations, philanthropic foundations, and other organizations that constitute the global polity. This analysis sheds light on the position climate capitalism-understood as a project of a section of the global corporate elite-occupies among international organizations. Overall, I find that climate and environmental policy groups: (1) maintain substantial ties to key organizations of the global polity, and (2) mediate a substantial amount of relations, bridging between central organizations and more peripheral ones, as well as among those located in Europe and North America. I thus argue that a global inter-organizational infrastructure exists that supports climate capitalism, which contributes to its dominant position in climate change politics.
