This paper, published in the UBC Journal for Climate Justice, explores and describes the potential benefits, differences, and feasibility of alternative sustainable models derived from various cultures across the globe, such as Buen Vivir, Ecological Swaraj, Ubuntu, and Décroissance. It illustrates how the décroissance model, in particular, can be used as an exemplar for alternative economic models. By providing policy recommendations, the paper demonstrates how décroissance can address major sustainability crises in areas such as housing, food systems, transportation, and labour.
