Earth system boundaries and Earth system justice: sharing the ecospace

Joyeeta Gupta et al

The literature on planetary and Earth system boundaries calls on humans to live within those boundaries. Sharing such limited ecospace raises questions of justice. Global environmental assessments and scholarship are increasingly paying attention to justice issues, yet inadequately define how to share the limited ecospace. Against this background we ask: how can global environmental assessments’ concerns for justice be enhanced through an Earth system justice framework that guides how the global community could share limited ecospace? Based on an analysis of how justice concerns are addressed in the Assessment of Assessments and global environmental change projects, we build an Earth system justice framework that discusses how ecospace can be shared fairly through the setting of Earth system boundaries and the provision of minimum resource needs for all, andhow this can be achieved through an equitable redistribution of resources, rights, and responsibilities focused on addressing inequality, overconsumption, and harmful accumulation.
