Fig. 1: Transformation needed to enter the safe and just corridor, while ensuring that all humans have access to basic needs.

The left figure shows the safe and just space in a specific domain in green, the outer limit is defined by the just no significant harm boundary. The safe boundary is less stringent than the just no significant harm boundary. The current use is beyond the safe boundary. These boundaries have been crossed and the minimum needs of people have not even been met in 2018—a gap that will increase in 2050 under business as usual. The right figure shows a world where the social SDGs have been achieved and the dark green area represents the use of resources by all humans to meet their minimum needs. The more stringent of the safe and just boundary marks the upper limit. The green space denotes the safe and just corridor. The diagonal arrows show the transformations needed from now to the future to ensure that we move into the safe and just corridor. Moving into the safe and just corridor is a necessary condition for justice, not a sufficient one.
