In this final inquiry report, the PC presents recommendations focused on three key policy reform areas:

  • Reducing the cost of meeting emissions targets
  • Speeding up approvals for new energy infrastructure
  • Addressing barriers to private investment in adaptation.

This inquiry report was handed to the Australian Government on 10 December 2025 and released on 19 December 2025.
