You might be aware that the NSW government recently released the 2036 regional plan for the South East and Tablelands, which includes not only measures for climate change mitigation and adaptation, but also recognises the role of the ACT despite the jurisdiction differences.
Increasingly, the scale of the challenge of climate change mitigation and adaptation is directly linked to land use-planning decisions, which by their nature demand a regional approach. It is a challenge that state and local governments are increasingly required to meet, as long as we continue to more generally see a lack of national government leadership on climate policy.
