Partnerships to Sustain Cape Town

  1. 1. Marvin Benjamin 18 November 2011, Cape Town Sustaining Cape Town
  2. 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. 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's population was living in cities Economic powerhouses In 2008 the largest 100 cities accounted for around 30% of global GDP
  4. 4. … that has also dawned in Africa <ul><ul><li>Population </li></ul></ul><ul><ul><li>1950: Two African cities with populations >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. 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. 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. 7. Coal-based energy production – an environmental risk Energy
  8. 8. Traffic congestion – a health risk Mobility
  9. 9. There are however opportunities (1) Energy
  10. 10. There are however opportunities (2) Mobility
  11. 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. 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. 13. “ 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. 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. 15. <ul><li>Thank you for your time and attention! </li></ul>
