By problematising ecomodernism in relation to key concepts of environmental political theory, the aim of this chapter is to outline ecomodernism as a distinct ideological approach to the Anthropocene, one that challenges many deeply held assumptions of traditional environmentalism and insists that ecological flourishing can be made possible, not by restricting liberal freedom or harmonising with nature, but through the progressive decoupling of the economy from the natural environment through state-led innovation. Yet, it is argued, the real-world impact of ecomodernism remains limited. In many cases, ecomodernism may end up becoming an excuse for political inaction, one which, just like degrowth, is unlikely to win sufficiently broad support in time to prevent aworsening destabilisation of the climate system.
