Frankfurt (Germany), 6-9 June 2011 Carsten Böse – Germany – RT 1a/5a  Transportation  Healthcare Biggest impact on Thought leadership initiatives on “Urban Infrastructures”  There is a broad spectrum of technical solutions available – already today  Technology investments have reasonable return rate  Achieving efficiency on infrastructure investment is crucial  Every region has to define its own prioritization  A central city management is major success factor Conclusion Vienna A model city of modern mobility with a high performance traffic system Munich Cutting Co 2 by 90% without impairing the quality of life of inhabitants London Two-third of all CO 2 -abating technologies pay back their investment Ekatarinburg ‘Care free package‘  Energy Efficiency  Water & Wastewater

5. Frankfurt (Germany), 6-9 June 2011 Sustainability Study – Example Munich Carsten Böse – Germany – RT 1a/5a  Munich can cut its carbon emissions by up to 90 percent by mid-century compared to 1990 levels –without impairing the quality of life for its inhabitants  Key levers: heat insulation for buildings, energy efficiency, renewable and low carbon power generation  Electricity requirements could be met for the most part from renewable sources  In a period of just 30 years low-carbon city districts could be realized Result of the study  Science calls for GHG emission reductions of up to 90 percent by 2050 from industrialized countries  Munich has set itself the goal to reduce carbon emissions by 50 percent by 2030  The study aims to develop a visionary model for a carbon free and sustainable Munich by mid- century to show that science’s targets can be met  The goal of the study was to show what alternatives are available and how they can be intelligently bundled to form sustainable solutions Motivation for the study
