Cities are often already overwhelmed by the number and complexity of services they need to provide. Adding climate change mitigation and adaptation to the other challenges facing cities is an enormous burden; and at the same time cities must accommodate another three million new residents every week. Cities also present enormous potential as the world’s report on cities and climate change. The report economies and wealth generation are anchored to discusses the link between climate change and cities, cities. Many countries and cities are taking why cities should be concerned about climate change advantage of urbanization, building on this and adopt early preventative policies, and how the economic growth.

Many people, particularly the poor, are cities and climate change. How cities contribute to already affected by climate change. The next decade and are affected by climate change. How policy will be particularly challenging.

However, cities can also be models of expected climate change, actions needed to cope environmental efficiency, because increased density with the challenges, and how cities can contribute and better management reduce the cost of service to that overall agenda.

CITIES AND CLIMATE CHANGE: AN URGENT AGENDA I 13 PART III Cities’ Contribution to Climate Change “We are increasingly interconnected—no city can wall itself off from the consequences of climate change, and no city can prevent catastrophic climate change on its own.� —KEN LIVINGSTONE Former Mayor of London (2007) Reasons for Addressing Climate government. National governments may set the Change at the City Level rules of the game, but it is cities that are the athletes. For the athletes to play the game, not only is it Cities are an organic form of government and often crucial that they know the rules, but also that their express the aspirations of their citizens more voices and those they represent are incorporated succinctly and quicker than higher levels of during the formulation of the rules. government. When these rising voices are credibly articulated, their global impact is considerable, and Climate change will require city administrations to growing, as the worldwide response to climate develop more robust partnerships with their change illustrates.

Urban design and mobility are crucial in CO2 emissions. It is not urbanization alone that Countries that rely on private transport use more increases emissions, but rather how people move energy per passenger kilometer than countries with about the city, the sprawl of the cities, how people high levels of public and nonmotorized transport use energy and how buildings are heated and cooled modes. As density increases, people use more public that make the difference in how cities pollute and transportation and nonmotorized forms of transport, contribute to climate change. For example, the lowering transportation energy use per capita (Figure United States produced 50 percent more 13). Good land use policies can encourage this trend. 7In Germany, this includes incentives to purchase electricity from renewable sources, waste management, insulation standards in new and renovated buildings, and environmental standards in public procurement. In Sweden, urban policies combined energy facilities and encouraged mixed, and dense, land use. Deindustrialization also played a role.

This variation in density and design is a major reason for the striking differences in per Figure 15 capita greenhouse gas emissions between newer cities City Densities and their Greenhouse Gas Emissions per Capita in the United States and older cities in Europe. The urban form is also driven by lower fuel costs in the United States. This is a critical lesson for developing- country cities that still have an opportunity to influence the final shape of their cities. GHG Emissions (tCO2e/capita) Compact cities are more sustainable than sprawling cities. Urban form is important in determining land and energy use and the cost of infrastructure and municipal services. Denser cities use less energy for transportation, which lower transport-related emissions. They also provide access to services at lower cost and implement more energy efficiency measures. The relationship between urban density and greenhouse gas emissions per capita is shown in Figure 14, emphasizing that cities that are denser produce less emissions.

METROPOLITAN INDICATORS Current research on urban form and density of cities reveals interesting patterns. The Neptis Urban density Road length per capita (population /hectare) (metres / person) Foundation has produced the following figures emphasizing the urban form, density and 40+ 0 –2 transportation characteristics of 16 world cities. Compact cities, such as Vienna and Madrid, have significantly higher population density and higher 30–40 2–4 public transport use than more sprawling cities, such as Atlanta and Houston. Spatial population density figures produced by Chreod Ltd. illustrate 20–30 4–6 density distribution for 10 world cities. Population density is highest in the city core of 10–20 6–8 compact Chinese cities, while spatial density variation is less pronounced in sprawling U.S. cities. Tokyo offers an interesting example; with 0–10 8–10 many dense city neighborhoods, Tokyo’s population density distribution is relatively spatially consistent throughout the city. Transportation mode share Metropolitan pro�le Private 75 Urban density, motorized Public transit, persons/hectare walking, and cycling Share of all trips Centre-line length by public transit and 75% 10 of all roads, non-motorized modes 0 m/person Annual distance traveled Private motorized Private by private motorized vehicle ownership, 70% motorized vehicle, km/person 21 000 800 vehicles /1 000 people The pie diagrams indicate the proportion of all trips made by private motorized vehicle (mostly cars, trucks, and motorcycles) and public transit, walking, and cycling. The star-shaped Metropolitan Pro�le diagrams graphically display the transportation orientation of the urban regions using �ve variables. If a city’s red polygon is shifted toward the upper left, as seen in some European cities, it is more oriented toward public transit, walking, and cycling. If a city’s red polygon is shifted toward the bottom right, it is more automobile oriented. The numbers at the end of each arm indicate each scale’s maximum value. Urbanized area of the metropolitan region Limited-access expressway Differing de�nitions and data make international comparisons of metropolitan regions dif�cult. Each region’s urbanized area map is based on a minimum population density and the contiguity of the built-up urban area, and adjusted to accommodate differences in settlement patterns. Only limited-access expressways are shown. Other roads and transit facilities such as subways and commuter railways are not mapped due large variations in their levels of service. For a complete description of data sources and mapping methodology, visit http://www.neptis.org/atlas/show.cfm?id=60&cat_id=29. Data sources INDICATORS URBANIZED AREA DEFINITION Transportation mode share, The urbanized area for each city is generated from government data sources. For the European cities, the de�nition is based centre-line road length, annual primarily on land uses that constitute the built-up urban fabric of a region. The extent of a European region is limited to those distance traveled by private local municipalities that are contiguous to the central municipality and have a minimum population density of 4 people per motorized vehicle, and vehicle hectare, a threshold employed by the US census bureau. For the U.S., Canadian and Australian cities, the de�nition is based on ownership statistics are from the urban area de�nitions employed by each country’s census bureau, a combination of population density measured within the Millennium Cities Database census geographic units and the contiguity of those census units. Some alterations were made to the urbanized area shapes 2001 by J. Kenworthy and F. to make them more comparable in area and extent. For the Canadian cities, the census-de�ned ‘urban area’ was used as a Laube, published by the Inter- base and large, green spaces and agriculture reserve land at the edge were removed using local data sources. For the U.S. and national Association of Public Australian cities, census-de�ned ‘urban area’ and ‘urban centre-locality’ were not altered since comparable density thresholds Transport. and �ne-grained census units were employed in the rule base.
