Crisis as Catalyst: COVID-19 as a Policy Window for Climate Urbanism in Barcelona

Abstract

The COVID-19 pandemic functioned not only as a public health emergency but also as a systemic shock to urban life, exposing deep-seated spatial inequalities and environmental vulnerabilities. This article examines whether and how the pandemic acted as a policy window for accelerating climate urbanism in Barcelona. Prior to COVID-19, the Catalan metropolis faced structural challenges, including severe air pollution, car-dominated allocation of public space, and uneven access to green areas. Drawing on John Kingdon’s Multiple Streams Framework and scholarship on urban experimentation, this paper argues that the pandemic catalysed the convergence of preexisting climate policy proposals, civic mobilisation, and political opportunity. Barcelona’s expansion of the superblock (superilla) model and the community-led green mobility initiative bicibús are analysed as forms of hybrid climate–health infrastructure: measures that simultaneously reduce greenhouse gas emissions, mitigate urban heat island effects, improve air quality, and enhance accessibility to public space. Rather than representing temporary or purely tactical responses to crisis conditions, these interventions illustrate how moments of disruption can accelerate longer-term structural transitions towards low-carbon, health-oriented urbanism. However, the durability of such transformations depends on governance capacity, sustained political support, and resistance from entrenched mobility and development interests. By positioning Barcelona as a case study of post-pandemic climate urbanism, this article contributes to debates on crisis-driven transformation and highlights the potential for cities to jointly leverage public health and climate change considerations to reimage sustainable and healthy urban futures.
