When it comes to air pollution, cities are fighting a permanent pandemic. In light of the magnitude of the problem, Barcelona architect and curator Olga Subirós recognised the urgency of addressing the climate crisis and public health emergency from an urbanistic point of view. Using Barcelona as a case study, the project Air/Aria/Aire analyses data sets to showcase the impact of air pollution from the urban scale down to the street level. An exhibition about Air/Aria/Aire, curated by Olga Subirós, will be presented at the International Architecture Exhibition 2021 in Venice, exploring the notion of air as a common good that is vital to people’s health and striving to respond to the Biennale’s theme of ‘How will we live together?’ – an even more vital question in times of coronavirus.
