Transformation of the Urban Energy-Mobility Nexus: Implications for Sustainability and Equity

In the coming decades, decarbonization of society in response to climate change will result in transformation of urban systems, especially in the energy and mobility sectors. This transformation will likely lead to stronger links between both sectors, which may have both desired and undesirable consequences. However, current policies are predominantly sectoral and tend to assume only a positive impact of the transformation of the energy-mobility nexus on urban sustainability. We conducted a systematic literature review, which covered 78 articles, to identify the interactions between the transformations of urban energy and mobility systems, their impacts on various aspects of sustainability and equity, and the relevant policies that target the nexus. The results show that the positive impacts of the transformation of the urban energy-mobility nexus are outnumbered by negative impacts on various aspects of sustainability and equity. A major equity issue concerns a possible reinforcement of socio-spatial inequalities in access to renewable self-production of electricity, electric vehicles, their integration, and the associated benefits. In conclusion, the issue of socio-spatial inequalities should be a priority for further research and policy development, given the currently limited understanding of these equity risks and the growing emphasis on the need for a just transition.
