To accomplish a just transition, energy scenarios is a helpful tool. Participatory and deliberative methods are increasingly used when constructing and assessing energy scenarios to improve the democratic legitimacy of the results. This article contributes to the scientific debate by analyzing how such methods can include considerations of justice issues in a more systematic manner. It is based on a study of four workshops conducted in Sweden, in which the participants discussed different energy scenarios from a justice perspective. It discusses what can be achieved by methods for participatory-deliberative ethics assessment of the consequences of energy scenarios and how such methods should be designed.
