Just green transitions pose complex challenges that need to be faced with an interdisciplinary approach, integrating a broad range of types of knowledge. While the inclusion of knowledges other than formalised expertise has been a long-standing theme in social-scientific research, the justice of such inclusion has not been addressed much. The inclusion of knowledge needs dedicated work to be done to make such inclusion just. As work in transitions is largely organised as projects, continuity across such projects is not granted, and mechanisms for institutional learning are vulnerable. Epistemic justice thematises how inclusion and exclusion of knowledge relate to the form and content of knowledge itself, and this chapter develops the idea that considerations of epistemic justice need to be part of the epistemic work done in the governance of just transitions and that this work needs to be shaped such that it acquires continuity across projects.
