“We all have a responsibility to learn how to live and develop sustainably in a world of finite resources.”– Archbishop Emeritus Desmond Tutu, 2009


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 CO2 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


…that has also dawned in Africa

Population

1950: Two African cities with populations >1 million

2010: Forty-seven such cities

2050: 60% urbanised (currently at 40%)

Economic powerhouses

African cities contribute 80% of the continent’s GDP

Large cities are economic centres (Lagos, Nairobi)

Globalisation impacting trade and infrastructure

Major energy and climate factors

Resource efficiency (energy and water) is key

Planning and good governance for sustainability

Cape Town’s population growth in the urban millennium

2.4% p.a.

2.8% p.a.

Population growth strains existing infrastructure

and could increases greenhouse gas emissions.

Challenges in the urban millennium

Mobility

Over the past decade, traffic volumes grew by 3% p.a. leading to lengthier travel

delays and more accidents

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


Coal-based energy production – an environmental risk

Energy


Traffic congestion –a health risk

“...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.”


What are cities doing on the sustainability path?

London

Low Emission Zone – battling air pollutionMasdar

Carbon neutral despite expansion of energy capacity

Abu Dhabi City

Desalination to address growing water demand
