Social policy developed as a research field and academic discipline to ensure protection from social risks in the era of emerging capitalism and industrialization. While welfare states have successfully increased their citizens’ wellbeing, they have also contributed to the ecological crisis, while the shared scientific understanding of exceeded planetary boundaries and worsening climate change scenarios has not (yet) reshaped mainstream social policy research. In this article, we suggest that the established traditions in social policy research can nevertheless provide a solid ground for responding to the climate emergency and facilitating the sustainable transformation of society and the economy. With a focus on four of the research fields that are central in social policy scholarship – risks, citizenship, welfare regimes, and wellbeing – we develop an ecosocial research agenda. By discussing the classic and climate-adjusted understandings of these fields, we open future pathways for social policy research and invite scholars to engage with our proposed research agenda.
