This class provides an in-depth assessment of the relationships between urbanization and climate change, and the central ways in which urban areas, cities, and other human settlements can mitigate climate change. The course explores two major themes: (1) the ways in which cities and urban areas contribute to greenhouse gas emissions and climate change; and (2) the ways in which urban areas can mitigate greenhouse gas emissions and climate change. Class topics parallel the IPCC 5th Assessment Report, Chapter 12, Human Settlements, Infrastructure, and Spatial Planning, and include spatial form and energy use, land use planning for climate mitigation, urban metabolism, and local climate action plans. The class format is reading-, writing-, and discussion-intensive. Students are taught how to synthesize scientific literature, write policy memos, and develop effective oral presentations on the science of climate change mitigation in urban areas. Enrollment limited to sixteen.
