3. Dr. Busch In 2010 ~50% of worldwide population was living in cities  increase from 3.5 bn to 4.7 bn until 2030 Population "Urban Millennium" 50% of world GDPis produced in cities with a populationover 750k 3/4 of energy consumed in cities; 80% of CO2 emission produced in cities Major energy and climate factor Regionalpower-houses Carsten Böse – Germany – RT 1a/5a

4. Thought leadership initiatives on “Urban Infrastructures” Conclusion Ekatarinburg ‘Care free package‘ • 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 Munich Cutting Co2 by 90% without impairing the quality of life of inhabitants London Two-third of all CO2-abating technologies pay back their investment Vienna A model city of modern mobility with a high performance traffic system Biggest impact on • Transportation • Healthcare • Energy Efficiency • Water & Wastewater Carsten Böse – Germany – RT 1a/5a

5. Result of the study • 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 Sustainability Study – Example Munich Motivation for 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 Carsten Böse – Germany – RT 1a/5a

6. Cities are a key element in the New Electricity Age • 75% of energy will be consumed in cities • 80% of CO2 emissions in cities • Optimization of energy mix • Increase efficiency • Systemic Optimization (Smart Grid) Carsten Böse – Germany – RT 1a/5a
