Cities are both major consumers of energy and producers of greenhouse gas emissions. Although urban areas only comprise less than three percent of global land area, some studies attributing up to 78 percent of greenhouse gas emissions to urban areas (Grimm et al., 2000) and others estimating more than 80 percent (Grubler, 1994; O’Meara, 1999). Urban form for cities varies by context, and, as such has different implications for climate change mitigation. Whether a city is dense and compact, or dispersed and sprawling can influence the residential, transport, and energy-use of urban dwellers.
