Planetary justice: a systematic analysis of an emerging discourse.

Justice concerns have been central to contemporary social and ecological debates for decades but have only recently made inroads into the Earth system centric discourses on the Anthropocene and planetary boundaries. Our focus here is the emerging discourse on planetary justice which has aimed to be a corrective to this lacuna. Our goals in this paper are to delineate the general parameters and novel contributions of planetary justice while also recognizing the emergent variability within this discourse. In order to accomplish these goals we analyze the discourse through three interrelated analytical themes: First, how approaches to planetary justice envision <italic>scope</italic> across different human practices and categories of humanity and nature. Second, how they envision <italic>scale</italic> across space and time. Third, how they envision the <italic>ecosocial purpose</italic> of planetary justice. [ABSTRACT FROM AUTHOR]
