As part of PennDesign’s Spring 2012 Lecture Series, Enrique Peñalosa spoke on mobility, quality of life and equity in urban environments. An accomplished public official, economist and administrator, Enrique Peñalosa completed his three-year term as Mayor of Bogotá, Colombia on December 31, 2000. While mayor, Peñalosa was responsible for numerous radical improvements to the city and its citizens. He promoted a city model giving priority to children and public spaces and restricting private car use, building hundreds of kilometers of sidewalks, bicycle paths, pedestrian streets, greenways, and parks. After organizing a Car-Free Day in 2000, he was awarded the Stockholm Challenge Award and rewarded by a referendum vote endorsing an annual car-free day and the elimination of all cars from streets during rush hours from 2015 onwards. While Mayor, Peñalosa also led efforts to improve Bogotá‘s marginal neighborhoods through citizen involvement; planted more than 100,000 trees; created a new, highly successful bus-based transit system; and turned a deteriorated downtown avenue into a dynamic pedestrian public space. Since leaving office, he has traveled widely to advise governments and officials on sustainable urban planning including New York City and Mayor Michael Bloomberg.
