Cities have to face serious sustainablity challenges
Mid-2007, 50% of the world population will be living in cities

Increasing scarcityof natural resources
Traffic congestion on city streets in Western Europe will increase 188% by 2010
Increasing mobility
Cities account for 80% of theworld’s greenhouse gases, while covering only 0.4% of earth's surface
Growing need forenvironmental care Malfunctions of critical infra-
structures pose high risks to urban economies: in 2003 3-day power outage in New York City caused loss of 1 bn USD
Growing demand forsafety and security
Urban air pollution causes an estimated 130,000 premature deaths each year in developing countries (Source: WHO)

Urban development is a key topic of Siemens’ research programs
Research approach
Research project undertaken with McKinsey & Company and the Economist Intelligence Unit
Describes a series of technological levers of varying effectiveness, and with different cost implications, which can all contribute to greater environmental sustainability in cities
Looks at financial andother implementation barriers to these technologies as well as selected strategies to overcome them
Sustainable Urban Infrastructure
Global research project undertaken by MRC McLean Hazel and Globescan, with the support of Siemens
More than 500 public and private sector experts from 25 global cities interviewed
Shows how challenges and solution approaches are prioritized for five infrastructures (transpor-tation, energy, water, health, safety & security) as well as for city governance and finance
