This study examined four scenarios to explore the possible impacts on employment, carbon emissions and energy use for the state of South Australia if it adopted certain practices to become a more circular economy in 2030:
- The business as usual scenario of the South Australian economy was established for 2030 based on existing baseline trends. All other scenarios are compared against this as the base case.
- The efficient and renewable energy scenario is based on the ‘towards net zero emissions’ energy efficiency, Low carbon electricity, electrification and fuel switching approaches set out in the SA Government’s ambitious Climate Change Strategy 2015-2050.
- The material efficiency scenario uses three key assumptions around material efficiency, use of secondary materials and longer product lifetimes, inspired by a 2015 report to the Club of Rome. To further investigate the role of biological materials in a more circular economy, the project team also included assumptions around renewable materials in long lived products and biogas.
- The circular economy scenario combines the material and energy measures, reflecting that a truly circular economy addresses the careful use of finite stocks of both energy and materials.
