  • 1. Marvin Benjamin 18 November 2011, Cape Town Sustaining Cape Town
  • 2. <ul><li>“ We all have a responsibility to learn how to live and develop sustainably in a world of finite resources.” </li></ul><ul><li>– Archbishop Emeritus Desmond Tutu, 2009 </li></ul>
  • 3. We live in the urban millennium… Urban Millenium Major energy and climate factors Cities consume 75% of the world’s energy and produce 80% of CO 2 emissions Population In 2007 ~50% of the world&apos;s population was living in cities Economic powerhouses In 2008 the largest 100 cities accounted for around 30% of global GDP
  • 4. … that has also dawned in Africa <ul><ul><li>Population </li></ul></ul><ul><ul><li>1950: Two African cities with populations &gt;1 million </li></ul></ul><ul><ul><li>2010: Forty-seven such cities </li></ul></ul><ul><ul><li>2050: 60% urbanised (currently at 40%) </li></ul></ul><ul><ul><li>Economic powerhouses </li></ul></ul><ul><ul><li>African cities contribute 80% of the continent’s GDP </li></ul></ul><ul><ul><li>Large cities are economic centres (Lagos, Nairobi) </li></ul></ul><ul><ul><li>Globalisation impacting trade and infrastructure </li></ul></ul>Major energy and climate factors Resource efficiency (energy and water) is key Planning and good governance for sustainability
  • 5. Cape Town’s population growth in the urban millennium Population growth strains existing infrastructure and could increases greenhouse gas emissions. Million Expected in 2015 2.4% p.a. 2.8% p.a.
  • 6. Challenges in the urban millennium <ul><li>Mobility </li></ul><ul><li>Over the past decade, traffic volumes grew by 3% p.a. leading to lengthier travel </li></ul><ul><li>delays and more accidents </li></ul>Water The demand for surface water is outstripping supply while adequate maintenance of infrastructure remains a challenge Energy Energy consumption is largely derived from carbon intensive sources Healthcare Despite existing initiatives (disease management, better air quality) more can be done (substance abuse) – investment needed
  • 7. Coal-based energy production – an environmental risk Energy
  • 8. Traffic congestion – a health risk Mobility
  • 9. There are however opportunities (1) Energy
  • 10. There are however opportunities (2) Mobility
  • 11. Cape Town is already pursuing sustainability with defined goals Targeted reduction in CO 2 (Million Tonnes) 2007 2014 20.0 22.7 10 278 2007 2012 -10% Targeted reduction in electricity use (GWh) 43% 57% 2020 47% 53% 2015 50% 50% 2010 52% 48% Pre-2010 % private % public Year Targeted transport modal splits Current 2020 Renewable Energy as % Total Energy 1% 10%
  • 12. Globally, cities pursue sustainability – an opportunity for engagement *16% below business-as-usual levels ** 40% below 1990 levels Implemented Planned/Drafted Not planned Solar energy solutions Energy optimisation / retrofit Green Building legislation Waste-to-energy programme Electric vehicles for public/private mobility Wind energy solutions 40%** (by 2025) San Francisco 16%* (by 2020) Singapore 12% (by 2014) Cape Town CO 2 neutral (by 2025) Copenhagen Carbon reduction targets Activities / Programmes / Goals
  • 13. “ ...my administration will explore avenues to make Cape Town a city desirable for green technology firms“. “ The creation of economic opportunities will also require a full appreciation of global trends with a view to … fulfilling our responsibilities to the environment. ”
  • 14. What are cities doing on the sustainability path? London Low Emission Zone – battling air pollution Masdar Carbon neutral despite expansion of energy capacity Abu Dhabi City Desalination to address growing water demand
  • 15. <ul><li>Thank you for your time and attention! </li></ul>
