Held from November 6 to 8, 2008, this ground–breaking symposium was organized to address the role of urban design in the face of one of the most profound and important challenges facing global society: the need to re–imagine and rethink how cities are designed and organized in a future without the plentiful and abundant oil upon which prosperous urban economies have been built.

The event marked the 50th Anniversary of the 1958 University of Pennsylvania/Rockefeller Foundation "Conference on Urban Design Criticism," whose participants included Jane Jacobs, Louis Kahn, Kevin Lynch, Ian McHarg, Lewis Mumford, and I.M. Pei. That historic conference helped shape the new field of urban design in the 20th Century. Now, we hope you will participate in this critical exploration of new directions for 21st Century urban design.

The "Re–Imagining Cities" program spoke to the depth and diversity of the challenge with sessions on innovations in the way cities are conceived, adapted, designed, developed, and managed in a post–carbon world. The conference concluded with a manifesto on educating the next generation of urban designers and how best to equip them for the road ahead.

An accompanying exhibition showcased innovative ideas, projects, initiatives, and policies from around the world that seek to reduce emissions by changing the way we inhabit cities. Documenting the rise in oil dependency, changing development patterns, and demographic trends, the exhibition threaded prescient theories and artifacts surrounding the 1958 conference with contemporary challenges of the urban design profession. The exhibition will be on display in other locations in the coming months. Check back for future locations.
