China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition

open access: yesAntipode, Volume 57, Issue 3, Page 830-861, May 2025.
Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.
