Our objective is to account for the transitions in urban form and personal transportation in Copenhagen since 1947. Sustainability objectives are currently framed as efforts to reduce CO2 emissions. Urban transportation is a key area of intervention. In public debates, political parties, experts, and citizens make assertions about what is possible by referring to past experiences. Our contribution is to explore the official histories of Copenhagen in order to account for the transitions in mobility during the last six decades. We make a critical application of the multilevel perspective (MLP), which is the most used theory to study transitions. Our application is critical because the context of urban mobility necessarily includes a discussion of urban form development; therefore, we suggest ways in which the MLP should be adjusted in order to account for the historical dynamics evidenced in the empirical material collected for this study.
