A safe and just space for urban mobility: a framework for sector-based sustainable consumption corridor development

Abstract

Non-technical summary The exponential growth of humanity's resource consumption over the last half-century has led to ecological decline while people's basic needs have not been universally satisfied. The ‘doughnut economy’ and sustainable consumption corridor concepts have gained global attention, providing frameworks in which the maximum allowable environmental impacts and the minimum social levels acceptable to lead a good life establish a guiding pathway to meet human needs whilst remaining within the Earth's carrying capacity. We apply this thinking to the urban mobility sector in this article in an attempt to formulate a ‘safe and just space’ for urban mobility. Technical summary The theoretical and broad application of the ‘doughnut economy’ and sustainable consumption corridor concepts are lacking in implementation due to a limited understanding of sectoral thresholds. This study highlights the weakness of sustainable urban mobility indicator studies which often lack connections to ecological ceilings and social foundations and, thus, lack the ability to show if a mobility system is intergenerationally sustainable or not. Therefore, this study aims to bridge this knowledge gap and develop a mobility sector-focused sustainable consumption corridor. It does so by using a collection of concepts and associated indicators ranging from sustainable urban mobility, sustainable consumption corridors, ecological thresholds, needs theory and mobility social impacts to mobility poverty. The output of this study is an initial design of a mobility-focused sustainable consumption corridor with suggested themes and indicators to measure the relative performance of a region in relation to the material dimensions of the corridor accompanied by a discussion surrounding spatial, temporal and sectoral corridor-defining thresholds. This work provides a novel first step in the direction of sector-based sustainable consumption corridors which can aid in providing a transformational alternative to the status quo through the implementation of safe and just sectors. Social media summary This article applies the ‘doughnut economy’ and sustainable consumption corridors to the urban mobility sector. It provides a framework for evaluating urban mobility systems in terms of their ecological impacts (the ‘ecological ceiling’) and providing for human needs (the ‘social floor’), and for defining a ‘safe and just space for urban mobility’.
