The Adelaide to Zero Carbon Challenge Ambition is to deliver Adelaide as the world's first carbon neutral city.

In 2013, the City of Adelaide emitted 939,532 tonnes of greenhouse gas. Stationary energy and transport were the main sources of carbon emissions, contributing 60% and 35% respectively.

Waste disposed to landfill contributed 5% of Adelaide’s emissions.

1. The big picture:

  • commercial energy use - 43%
  • residential engergy use - 3%
  • industrial energy use - 5%
  • electricity network losses - 9%
  • transport fuels - 35%
  • waste to landfill - 5%

2. Main areas of engagement:

  • energy
  • transport
  • waste

3. Developing our main areas of engagement

  • Energy consumption
    • commercial - 74%
    • residential - 4.5%
    • industrial - 7.5%
    • T&D electricity losses - 14%
  • Transport emissions
    • passenger - 91%
    • motorcycle - 1%
    • truck - 0%
    • public transport - 8%
  • Waste to landfill
    • landfill waste - 99%
    • wastewater - 1%
    • greenwaste - 0.1%
  • Liveability
    • We’re looking for ideas that can reduce emissions and also make our city more liveable – it could be in our parklands, the streetscape and the intersection between the built and natural environments as well as cultural, entertainment and recreation opportunities. For example, increased tree canopies improve the liveabilty of the city by reducing the urban heat island effect. In Adelaide, increased tree canopy cover has been shown to decrease the temperature of areas of the city by up to 9 degrees. It might be you have a great idea about water, clean green food from our healthy environment or how to make our city more vibrant that will increase the liveability in our city while making a difference to carbon emissions.

4. What are we looking for?

Our process identifies seven value creations against which we will evaluate the validity and effectiveness of any proposed competition entry. They are as follows:

  1. significant impact
  2. cost effectiveness
  3. economic benefit for South Australians
  4. co-benefits
  5. engagement
  6. credibility
  7. visibility

5. What is the selection criteria?

E1. Project appears to be technically feasible.

With the limited information provided, there do not appear to be any technical fatal flaws presented. For example, it is not a perpetual motion machine or similar!

E2. Project will reduce carbon emissions within the City of Adelaide (CBD + North Adelaide + (Parklands)

The impact of the Project will be that emissions from Energy, Waste or Transport are reduced within the City of Adelaide. Other emissions reductions might be considered after review but it is these three priority areas that are of most interest.

E3. Project can be primarily delivered within South Australia

The Project itself does not need to be delivered within the boundaries of the City of Adelaide but should be primarily delivered within South Australia. For instance, parts might be manufactured elsewhere in SA but installed in the city, or waste might be taken from the city and utilised in an innovative way elsewhere within SA.

E4. Project appears to be innovative and original

Whilst it is impossible for the Jurors to know whether the Project is entirely innovative, to the best of your knowledge is the Project something that does not appear to have been done globally in the same way as proposed?

E5. Entrant is willing to enter into a local partnership in the delivery of the project

Where the entrant is outside of SA, is the proposal structured so that it can be delivered with a local partner company?

M1. An innovative solution that will help the City of Adelaide to become the world’s first carbon neutral city.

Has the potential to deliver a unique low carbon solution in Adelaide that might later be exported to other cities.

M2. Reduces emissions in the City of Adelaide.

Has a material impact on emissions within the city boundary with respect to Energy, Waste or

M3. Improves the liveability of Adelaide and the lives of our community.

Has the potential to have a significant impact to how people live in Adelaide if adopted widely.

M4. Develops new partnerships, attracts investment and creates opportunities for local business, new economy jobs, and industries.

Delivers economic development benefits to the city.

M5. Strengthens entrepreneurial and innovation capacity in low carbon technologies, renewables and clean technology.

Has the potential to drive or inspire further low carbon innovation activity.

M6. Provides a catalyst for local action and behaviour change.

Engages the community in a way that has the potential to have a significant impact on emissions.

M7. Has great potential but needs an initial support to enable further development.

Has a need for funding or, in other words, it is unlikely to happen without the support offered by the Prize.

Outcome: Adelaide is the world's first carbon neutral city.
