Degrowth and environmental justice movements share overarching aims of sustainability and justice and pursue them through radical social change and resistances. Both movements are diverse and comprised of groups that originate and operate in different contexts. The ever-growing metabolism of the world economy presents an obstacle to both movements' aims, while a socio-metabolic perspective unveils very different characteristics and contexts of the specific struggles. The strategies of many environmental justice movements located at the frontiers of resource extraction are employed to resist coerced socio-ecological transition towards industrialization and to protect more customary ways of life. Movements for the degrowth of industrial metabolism tend to push for socio-ecological transformation, pursuing new ways of life and reimagined social relations in alternative societies. The overarching aims and obstacles of these movements may be shared, but their struggles, strategies and required actions are not the same. Alliances should seek advantages from this plurality of perspectives and positions within their struggles, while acknowledging potential tensions arising from these different contexts.
