Minoritised youth voices are often underrepresented in climate action research. Despite the increasing interest in youth climate activism, there is still an overall lack of attention to the perspectives of young people struggling with discrimination, poverty, and other social injustices. In this article, we focus on a diverse group of minoritised youth in Portugal to explore their experiences of climate activism, perceived agency, and political imaginaries of the future. We conducted a qualitative study involving seven focus groups with 55 participants, including young people with a migrant background and/or living in underserved communities in Portugal. Based on a Reflexive Thematic Analysis, we generated three main themes that illustrate participants’ ways of engaging with climate change issues, the barriers that constrain their engagement with climate activism and the challenges in the political imagination of the future. Our findings suggest that minoritised youth would like to have a voice in political debates about climate change and that more inclusive dialogues about climate futures could help bridge existing territorial and social divides. info:eu-repo/semantics/publishedVersion
