Abstract Harmony with nature, pristine countryside, organic farming, a vegan diet, renewable energy, sustainable development. This imagery tends to be associated with ‘green liberal’ environmentalist movements and more broadly, left-wing political ideologies. However, concern for the environment and warnings about the imminent climate crisis are gaining traction within far-right and white supremacist movements. This article focuses on the revival of white supremacist environmentalism based on a qualitative text analysis of an English-language manifesto published by the violent extremist neo-Nazi Nordic Resistance Movement. Drawing on the concept of axiological cosmologies from Legitimation Code Theory and the Appraisal framework from Systemic Functional Linguistics, this paper shows how an ecofascist ideology is built up through clusters of meanings that reinforce neo-Nazi grievances such as ‘global Zionism’, ‘mass immigration’ and multiculturalism. The paper concludes by discussing the implications of what the promotion of eco-fascist ‘solutions’ to the climate crisis could mean for climate justice from a human rights perspective and preventing violent extremism from an educational perspective.
