"In this introduction to the special issue of Sociologia del lavoro, devoted to labour transformations and welfare policies in the context of the ecological crisis, the authors review the state of the debate, focusing on three emerging concepts: climate justice, just transition and sustainable welfare. They provide an analysis of the academic and non-academic contexts in which these concepts have emerged and the kinds of programmatic questions that they raise for the study of labour transformations, social movements and welfare policies. After discussing how the collected contributions operationalise the three concepts in different empirical and research contexts, the article outlines some critical gaps that warrant being addressed or explored further and propose a few methodological and analytical pointers that are useful for the continuation of the debate and, thus, the growth of a field of analysis that is destined to occupy a major space in the sociology of labour.'
