While there are many possible successful pathways to future development in the context of climate change, history has shown that pathways that are positive for the vast majority often induce notable impacts and costs, especially on marginal and vulnerable people , placing them in direct contradiction with the commitment to 'leave no one behind' . Similarly, contemporary scenario analyses find that there are plausible development trajectories that lead towards sustainability . Yet, a number of plausible trajectories that perpetuate or exacerbate unstainable forms of development also appear in the literature . A significant challenge lies in identifying pathways that address current climate variability and change, while allowing for improvements in human well-being. Furthermore, while a given pathway might lead to a set of desired outcomes for one region or set of actors, the process of getting there may come at high environmental, socio- and economic cost to others  . Frequently, considerations of social difference and equity are not prioritised in the evaluation of different development choices. The assumption that a growing economy lifts opportunity for all could, for example, further marginalise those who are the most vulnerable to climate change .
