The article discusses five literature strands’ approaches towards social protection systems in the context of climate crisis: Adaptive Social Protection, Just Transition, Green New Deal, Post-growth, and Eco-feminism. As we argue, these five strands are located on a spectrum between a green growth orientation and a green anti-capitalist orientation. Furthermore, they differ in terms of their problematisation of the climate crisis and have different perspectives on relevant actors, on world regions, and – most relevant in the context of social welfare – their conceptualisation of social protection. While Adaptive Social Protection emphasizes cash transfers and insurances, Green New Deal and Just Transition approaches focus more on redistribution and labour market policies, and Post-growth and Eco-feminist approaches more on universalist policies and systems. We argue that these literatures each have their weaknesses, but also offer urgent questions, concepts, and insights for further social policy research.
