Introductionp Clear relationship between the transport
sector, energy consumption and the impacts of climate change
p Government policy direction focused on public transport (and non-motorised transport) over private vehicles
p 2010 legacy of sustainable, efficient, reliable and safe transport system, based on public transport

Transport, Energy and Climate Change

Energy Consumption in the Transport Sectorp The transport sector consumes approximately
20% of global energy reserves and 13% of GHG emissions
p It consumes up to 90% of oil reserves, globally p Concerns around
■ Global peak oil; ■ Increased urbanisation and economic development in
developing countries ■ Increased use of private vehicles
p Impact on the future of private vehicles as the preferred mode of travel
p Decrease in fuel consumed = a reduction in CO2 emissions

2010 World Cup Travel Plans and Projectionsp 2010 resources used to create a lasting
legacy of quality transport services, infrastructure and systems – focused on public transport
p Green Goal target of 50% of spectators using public transport to and from the stadium of match days
p UNDP/GEF funded projects (with NDoT and 2010 Host Cities) aims to mitigate GHG emissions through implementation of sustainable transport systems
![Page 17: sustainability and energy issues and implicationssacitiesnetwork.co.za/wp-content/uploads/2014/10/sustainability_an… · (Energy and Climate Change Strategy) p Economic Commuter](https://reader034.fdocuments.us/reader034/viewer/2022042403/5f15be945c78861e555873be/html5/thumbnails/17.jpg)
2010 Travel Demand Projectionsp The number of international visitors is greater
than every experienced in the country p International visitors projects @ 700 000
throughout the event (½ without tickets) p The maximum number of international visitors
with tickets will be 220 000 on day 5 p The maximum number of international visitors
(with and without tickets) will be 400 000 on days 12 and 13
p The current transport systems can currently not deal with these numbers adequately

UNDP/GEF Sustainable Transport Projectp Part-funding of transport systems improvements
in 7 2010 Host Cities ■ Johannesburg, Nelson Mandela Bay, Polokwane,
Mbombela, Mangaung, Rustenburg and Cape Town ■ Focused on improvement of public transport, road
management, non-motorised transport and travel demand management
p The project aims to reduce or avoid CO2 emissions in the order of 423 000 tonnes of CO2 (over a 10 year period)
p Aim to increase the annual number of person trips on sustainable transport modes by 20% (over a 10 year period)

Making the Case for Public Transport
![Page 20: sustainability and energy issues and implicationssacitiesnetwork.co.za/wp-content/uploads/2014/10/sustainability_an… · (Energy and Climate Change Strategy) p Economic Commuter](https://reader034.fdocuments.us/reader034/viewer/2022042403/5f15be945c78861e555873be/html5/thumbnails/20.jpg)
The Case for Cape Townp 10% shift in commuters from private to public
transport by 2020 (Energy and Climate Change Strategy)
p Economic ■ Commuter savings on fuel and maintenance costs ■ Reduced road maintenance costs
p Environmental ■ Reduction in fuel used by private vehicles ■ Reduction in CO2 emissions and air pollution
p Social benefits / Poverty alleviation ■ Assess to employment, education, health ■ Decrease air pollution, which lead to improved health ■ Decrease in daily traveling time

Concluding Remarksp Sustainability and energy considerations cannot
be ignored in transport planning ■ The relationship between energy use (liquid fuels in
particular) and transport ■ The impacts of global peak oil
p Move towards sustainable public transport ■ More energy-efficient service ■ More environmentally-friendly
p Planning and implementation in an integrated manner taking into account the energy and sustainability issues and implications
