The paper first introduces the concept of ecosocial innovations. These are local organizations embedded in social and solidarity economy, which combine ecological and social challenges in their work. They are successful models of how to operationalize sustainability. Based on a cross-national, multi-case study with a social work background, the paper aims at providing insights about the work and significance of ecosocial innovations. Drawn from interview material collected in four countries within selected ecosocial innovations, seven themes as common characteristics of these local actors are presented. One trait of ecosocial innovations is a creative mix of paid work, voluntary engagement, and subsidized employment in their activities. This mix is not only a compromise due to a lack of resources, but it also acknowledges the interconnectedness of well-being and sustainable social practices. The paper concludes with a summary of the main results and an outlook of the potential of ecosocial innovations for the future. They could for example serve as models for an ecological social work.
