This is another initiative of the Greening Durban 2010 Programme. The aim is for Durban to run a carbon-neutral World Cup in 2010, and a number of projects have been established to try and achieve this. The Greening Moses Mabhida Stadium (the main Durban stadium to be used in the World Cup) focused on making the reconstruction of the old Kings Park stadium completely carbon neutral, by off-setting all the carbon emissions of building, running and maintenance process. This contributed to 62% of the total footprint of the event – a significant part of the carbon offset. Although all tenders for building the new stadium had to focus on “green” stadium design, the eThekwini Municipality then carried out a Green Review of the stadium, looking for further ways to add to the greening process. The process involved specific plans for Sustainable Waste Management, Water Resource Management (including demand management, storm-water control, and pollution avoidance), Energy Management (including demand management and proper maintenance), Transportation Systems Management, and Sustainable Landscape Management. The demolition of the old stadium was also taken into account; and the entire process has been calculated to be carbon neutral.
Innovation: Creating entirely carbon-neutral stadia is an ambitious goal, but one that the eThekwini Municipality has set for itself in its preparation for the 2010 World Cup. This initiative has now also been taken up by other host cities, including Cape Town, Rustenburg and Polokwane.
Effectiveness: The Stadium Energy Footprint has been reduced by 30%, through sustainable building design that maximizes natural ventilation, minimizing the need for air-conditioning. Energy-savings have also been achieved in the mechanical and lighting systems. The Stadium Water Footprint was reduced by 74%, through implementing efficient water fixtures, rainwater harvesting and residual re-use, waterwise landscaping, and good irrigation designs. In terms of Waste Management, all the concrete from the demolished Kings Park stadium was used to create the base for the new stadium; and over 400 tons of steel, 4000m³ of topsoil, and 40 000 bricks were recovered, re-used at local schools or recycled. There are also systems in place for waste separation at source, secondary separation at a depot within the stadium, and holding and collection for recyclables. There are also composting facilities to reduce the amount of green waste sent to landfill sites.
Poverty Impact: The energy footprint reduction will save approximately R700 000 per annum in running costs; the water footprint reduction will save roughly R703 000. The value of recovered materials through the waste management programme was around R950 000, and the value of the pre-cast concrete seats was roughly R1m. The project has also succeeded in creating a carbon-neutral stadium, which contributes to the ongoing goal of lessening the impact that cities have on their environment.
Sustainability: Once construction of the stadium is finished, the main sustainability goal will be ensuring that the stadium remains carbon-neutral in the future. The design and planning of the project included offsetting future emissions; thus hopefully the gains from this project will continue as long as the stadium is in use. The project has also meant that a number of contractors have had to develop green building strategies, which can hopefully be used on future construction projects in the city. The Green Building Council of SA was also established, which will encourage further green building in the future. The majority of the funding was supplied by the eThekwini Municipality (R2.6billion); while the remainder came from DANIDA (R4.17m).
Replication: Similar projects have already been run in 3 other host cities in South Africa (Cape Town, Polokwane, and Rustenburg.). It is unlikely that projects on this scale will be replicated very often, as this is in response to an extraordinary event (the Football World Cup). However, similar projects on a smaller scale (eg. to develop other smaller sports grounds, office buildings, housing estates) could easily be replicated all across the country. Depending on the scale of the project, it would likely require sufficient support and buy-in from local municipalities or communities; and would also require funding. But as greening seems to be the way forward, it would make sense for more companies to begin to include carbon-neutral plans in all construction projects in the future.
