Multiple land uses are competing for the same space to address spatial challenges such as the renewable energy transition. Decisions about which land use will be located where are not only made based on efficiency, but also based on value judgments by different stakeholders on what is the most just solution. However, different stakeholders have different ideas of what just planning means, and there are currently no discussion guidelines or assessment tools available to make these different perceptions of justice visible in spatial planning. This research aims to create these tools to make justice more explicit in spatial planning processes.
