In this paper I explore some of the roles that education can and needs to play in supporting “the great socio-ecological transition”, with particular emphasis on adult and vocational education and training. After briefly outlining some of the facets of the current pluricrisis, I examine a set of intersecting debates about transformation and transition(s) towards a more sustainable future, which is necessarily also more just. In this analysis, I build beyond the social science traditions usually evoked in these debates to draw on Catholic analyses of the nature of the problem. Catholic Social Teaching began with a concern about the effects of the transition to industrialisation, with Rerum Novarum (published by Pope Leo XIII in 1891), and increasingly has sought to address the need for the next transition beyond the Capitalocene, especially in Laudato Si’ (published by Pope Francis in 2015). It has always placed workers, work and learning at its core. Thus, there is much potentially to be gained from bringing together conventional educational research perspectives on education for sustainable development and education for human development with a Catholic Social Teaching lens in thinking about the possible roles for education in supporting just transitions.
