South Australia’s Climate Change Challenge and Opportunity Ross Garnaut September 2020 PB South Australia’s Climate Change Challenge and Opportunity Ross Garnaut September 2020 1 Summary of key points South Australia has a compelling interest in the success of the global effort to reduce damage from climate change.

Its rich agricultural endowment of human skills and experience for areas share the Mediterranean climates that understanding, mitigating and adapting to climate have been the first to experience disruptive change and utilising low-emission technologies warming and drying all over the world. It is for economic development. The Government of damaged by the shrinkage of water flows South Australia has always been at the forefront through the Murray–Darling river system. South of innovation for the transition that the world must Australians’ health and wellbeing have recently make soon to zero net emissions. been disrupted by the most severe bushfires on record and are affected by more and more South Australia has a compelling interest in frequent extreme heat. South Australia stands the success of the global effort to avoid the out in a vulnerable world for its vulnerability to worst effects of climate change. It would be climate change. damaged immensely by failure. It can prosper exceptionally in success. At the same time, South Australia is better equipped to respond to the challenges and opportunities of climate change than any other Now is the right time for Australian state and nearly all of the world’s high levels of investment in sub-national jurisdictions. It used to have more expensive and less reliable wholesale the low-carbon future electricity than the more populous states. With more electricity coming from solar and wind The international scene is right. While traditional and investment in balancing technologies, that trade and investment will remain weak in a has been reversed. Low electricity prices can depressed global economy, there will be be the foundation for global competitiveness opportunities in building the low-carbon global in new manufacturing, including the processing economy. For the time being, uncertainties exist in of South Australian raw materials into zero- the United States (US), but the world now seems emission products experiencing strong likely to emerge from the pandemic recession international demand now and increasingly in with strengthened commitment to meeting the future. South Australia has large opportunities objectives agreed in Paris in December 2015. The for producing biomass on land and in the sea, international economy is ready for deepening trade which will become increasingly valuable as the and investment with Australia if we embrace the world moves to zero net emissions. It has rich low-emissions transition. opportunities for sequestering carbon in its landscape, sea and geology. COVID-19 has tipped us into by far the deepest Australian recession since the Great Depression. The Government of South Australia, under South Australia has thus far fared better than both major political parties, has implemented the most populous states in containing the virus productive responses to climate change. It has but shares the nation’s need for large business led transition to a lower cost and more secure investment to restore incomes and employment. and reliable low-carbon power supply, and is Business is ready to commit large amounts of leading transformation elsewhere in the economy. investment in the low carbon economy in South It is providing sound and clear information about Australia.

Few South Australians are aware of how tall their state stands in innovation in the low-carbon economy. Drive by electric car or bus from Adelaide, around the coast through Port Augusta and Whyalla to Port Lincoln, with a short detour through Jamestown, and you will see in operation or under development many of the leading zero- emission energy technologies. These include a solar-thermal-powered arid-zone greenhouse; the world’s largest battery; innovative virtual power plants; floating solar; many large solar and wind farms; innovative use of algae; synchronous condensers; and development sites for pumped hydro and renewable hydrogen. No drive of similar length in the world would expose you so intensively to the energy systems of the future. Start in Mt Gambier on a longer journey and you will see even more, including the use of pyrolysis to convert wood waste into char and energy, and biomass heating systems for a greenhouse and aquatic centre. Along the journey, you pass centres of world-class research and innovation related to constraining the increase in temperatures and adapting to climate change. South Australia’s high standing on climate change and the energy transition can attract interest, visitors, innovative new citizens and investment. 4 South Australia’s Climate Change Challenge and Opportunity Ross Garnaut September 2020 5 South Australian emissions and the mitigation challenge South Australia, like all Australian states and A 50 per cent reduction by 2030 is within reach, with territories, aims to achieve zero net emissions by major contributions from low-emission manufacturing 2050. This objective is broadly in line with the Paris and mining,
