That cities have the potential to be the most sustainable form of human development is coming to be widely recognized, as is the fact that most cities have a long way to go to realize that potential. Progress is being made, however, in terms of improvements to infrastructure and the building stock, innovative transportation and development policies and programs, revised codes, and other measures designed to encourage sustainability. This course will examine the most innovative approaches to greening cities around the US and other countries and consider both their successes -and failures- and their applicability to different regions and cultures. Among other things, the important role of conflict resolution as major changes are being made in a city will be considered.
