The road to COP30

Looking ahead to COP30 and the next round of Nationally Determined Contributions (NDC 3.0), what cities and regions do in advance of this global climate summit may matter more than the conference itself. On the road to Belém, local and regional governments have a unique opportunity to engage with their national governments, shift the trajectory of the climate emergency, and push for inclusive, multilevel climate action.

City of Adelaide, Australia

Adelaide is the capital of South Australia, one of Australia’s six states. Home to 1.3 million people, it ranks among the world’s most liveable cities due to its strong performance in health, education, infrastructure, and environment.

An ICLEI member since 2015, the city is led by Lord Mayor Jane Lomax-Smith, who joined the Daring Cities Bonn Dialogues in June 2025 to share insights on how Australian local governments are advancing climate action.

Known as a “city within a park,” Adelaide is surrounded by 760 hectares of heritage-listed Park Lands, the largest inner-urban park system in Australia. With 33% tree canopy cover and a target of 40% by 2035, Adelaide is setting the pace as a climate-ready, green city that fosters healthy, active living.
