This article critically examines the challenges of trade union “just transition” (JT) policies in the context of the ecological crisis. While JT policies have grown in prominence, especially in the Global North, they do not adequately address the ecological crisis since they focus exclusively on decarbonisation without recognising that Green Growth, by reducing emissions increases environmental destruction created by the extraction of ever more minerals and metals. JT policies are further constrained by national boundaries and by a policy centred on jobs only, without acknowledging the broader needs for dignified lives and a regenerative relationship between labour and nature. Research into workers’ visions for the future shows that workers long for cooperation, democratisation from below, a connection of local and global solidarity, and more time to care for themselves and others. The author suggests that unions could connect with such visions to develop transformative, globally coordinated JT strategies that centre on cooperation and self-determination, allowing them to move away from growth imperatives towards a regenerative economy that centres on care for both, people and nature.
